Comments on: Palm TX Modified for Voice Recording

Palm OS programmer Dmitry Grinberg has added voice recording to his Palm TX with a few spare electronics parts. All that he added was a capacitor, resistor, a small microphone inside the case and the voice recording software from the LifeDrive.

1 down, 5 to go...

sremick @ 11/28/2005 3:30:12 PM # Q
Sweet! 1 down, 5 to go:

- Vibrating alert
- charge/alert LED
- speaker pointing to front where it makes sense and is actually useful
- G1 option
- SD slot dust flap

Not sure why we're not only Palm's beta-test group, but their R&D group as well...

You can already get G1 on the TX by using Igor Nesterov's hack. Just do a full backup first, because it can sometimes cause a hard reset.

- Vibrating alert>

this is 2nd on my mod list

- charge/alert LED

this is first on my mod list

- speaker pointing to front where it makes sense and is actually useful

this is not on my mod list at all

- SD slot dust flap

this is #4 on my mod list

what's #4?
camera.
why?
because its same proc as zire 72. no chip for cam. processor has camera support built in so its just a matter or wiring it to it and copying camLib :-)

Full CDMA Bluetooth support would be nice for the CDMA phones that DO support DUN profiles. I'd offer $50 PayPal immediately if a working solution was achieved.

SUPERB work, by the way.

And, 100% stable G1 would be superb (ie no crashing in text entry boxes in Blazer) etc.

>Cool hack, but where's the step by step?

here:

1. go to radioshack and by the cheapest wired headset you can find ($9.99 likely) it should have a wire then a mic module then a wire to earbud

2. crack the mic module open and desolder the microphone.

3. open the TX, disconnect the cables from LCD and Buttons and turn the motherboard over so you see the side with the processor on it

4. solder mic in as i showed here: http://www.palmpowerups.com/priv/diymictx.jpg

I wonder how many $304 Tx sales were lost so that you could save $5 on a Tx without your "kitchen sink" voice recording?

$5 is all it costs me to buy those components at retail in the UK, I'm sure that even Palm could have negotiated a greater volume discount on these components.

It's not so much the parts themselves as it is the fact that they'd have to redesign the TE style case to accomodate things like a microphone, LED, and decent power button. To do even those minor tweaks would cost a lot more than just buying the parts. Retaining the same case design is one of the reasons that the T5, TE2, and TX have to be insanely cheap for Palm to produce. I'm not saying it's right, just that you're suffering because of Palm's greed in the past, not any current greed.

RE: 1 down, 5 to go...
Simony @ 11/29/2005 5:13:34 AM # Q
Agreed. If they are to redesign the case for basic units like the TE2, I'd prefer it if they made the new unit much thinner and lighter (ie, rather than adding microphones, vibrating alarms, etc).

> $5 is all it costs me to buy those components at retail in the UK, I'm sure that even Palm could have negotiated a greater volume discount on these components.

Yes, but add the incidental costs the manufacturer would suffer - transport and storage, additional working capital costs, etc. Then add the manufacturer's mark-up on top of that (contract manufacturers often use a 'cost plus' pricing methodology). Then add the wholesaler's mark-up to that and then the retailer's mark-up on top of that. Then add sales tax to the retail purchase price.

If the manufacturer, wholesaler and retailer mark-ups are 30%, 50% and 50% respectively, a $5 component would add $14.63 to the retail price (before sales taxes).

RE: 1 down, 5 to go...
ChiA @ 11/29/2005 8:47:56 AM # Q
Simony said Yes, but add the incidental costs... blah blah blah

You've missed the point, $5 is the RETAIL PRICE of the components, i.e. how much I, as an end of chain consumer, pay for buying them in the shop. That means all these mark ups and taxes you refer to are already included in the $5 price. It'll be cheaper still for Palm as they'd be paying wholesale prices for these components.

True, a case design would have added to the cost of the unit; it's ironic that one man could get a microphone to work well without any case modification whereas a company full of designers, engineers etc couldn't! Someone at Palm should give Dmitry a job!

In fairness we don't know what effect the microphone has on battery life.

hkklife @ 11/29/2005 12:10:27 PM # Q
A case redesign might've have cost XXX dollars, yes BUT look at it this way:

They redesigned the back panel of the TX to accomodate the larger reset button. In a horrible pinch they could've mounted the mic opening somewhere on the back panel. A muffled VR is better than NO VR!

Secondly, this is going to be Palm's main meat'n potatoes non-Treo model for the fall of '05 and through most of '06. A FEW $ could have been scraped out of the coffers to redesign the top panel ONLY of the unit.

They could have added, with very little rearranging/modding:

1. Charge LED and/or a better sized/bulbous power button
2. Mic opening for a voice recorder
3. (Debatable) A small remappable hard button for screen rotation/wireles on/off ala the Treo, Then they could have had a LD-style DIA bar with the home button & wireless icons on it but relegate screen rotation to a hard button somewhere. The TX could then still use the same bottom panel and front/rear bezels it has now.
I'm not an injection molding or tooling expert but this doesn't seem like a huge challenge. With the costs reduced from the T5 by both feature-cutting & economies of scale, a charge LED & a VR would NOT be big deals to include!

Or here's something I suggested here earlier this year...they could've adapted the Zire 72 case design by making it black, dropping the camera, adding an Athena connector & 320*480 screen and ended up with an arguably better TX design.

Perhaps the modification violates someone's patent.

Maybe there are unusual feedback problems that show up when inside a car that couldn't be overcome.

Perhaps...well, ya get the idea - maybe upfront simple cost was not the reason.

hoodoo @ 11/29/2005 2:45:36 PM # Q
I had a quick look at the specs on Palm's web site:

The T5 and TX cases are exactly the same. So no mods there. The case for the TE2 is slightly different in height (6mm) and width (1mm), so therefore the T5/TX would have required a new injection mould anyways, so they could have made changes for mic's and led's when introducing the T5.

As far as running the business for accounting purposes, the cost of the TE/2 case would have probably been amortized to zero by the time the T5 was introduced, so the T5 design was probably changed slightly so they could amortize it again.

Either Palm liked the styling so much, or they could only afford couple of hours on the CAD program to redesign the T5. :)

I think everyone has missed the point.. I dont think its a matter of cost or re-engineering or whatever. I think its a deliberate marketing move to provide some differentiation between this and the lifedrive / any future models.

As for the vibrate alarm that is the one thing I desperately miss. The Lifedrive did not have one of those (I cannot fathom why) so they could not put one in this unit either. why does no current palm model have a vib alarm!!!! dimitry is going to have his work cutout to put in a vib alarm since the current required will likely necessitate additional driver circuitry (I will scream if its already in there) and mounting etc will be difficult.

nb: I recently traded my lifedrive for a TX and could not be happier!

Not to brag or anything, but I have all of these on my T|T3.

Ironically enough, I use all of those features (cept for G1. I'm happy with G2, but not that unhappy with it that I would switch back to G1). I just didn't know it till i paid attn.

On the flip side, I wouldn't mind having pictures in Contacts, wifi, more updated BT, more updated OS, and even more one handed navigation in all.... but I just wouldn't give up the T|T3 for the T|X. The pics in Contacts would be nice, but everything else would get used very little. I hear in some places, the enhanced one handed nav is more trouble than its worth.

Thanks to everyone for their thoughts on this. While a number of us are passionate about the need for voice recorders, vibrating alarms, etc, I can't help thinking that we are mising the wood for the trees.

Let me give you a 'for instance'. I went to a meeting with 4 investment bankers yesterday - 3 of them had blackberries. At one stage, I took out my TE2 to check my availability for a proposed meeting, and they asked me what kind of 'blackberry' it is. I told them that it is a 'palmpilot' - they looked at me like I was a martian - so then I said that it is a just an 'organiser' which does not have email - and they made some derisory remarks about it. (It was only when I showed them a spreadsheet with Docs to Go they they were even mildly interested.)

Having played with a blackberry for about 5 minutes, my impression is that it is pretty primitive, both as to software and hardware. However, it does have 'push' email and you can use it to make calls. Which is what a lot of people are happy to pay for.

The sooner that Palm can get 'push' email for the Treo line the better. In addition, they need to cut the price of the Treo line, to make a viable option for more people and to force out competitors.

whitemiata - do you really think a small little buzz from a vibrating alarm would cause more shock to a micro drive vs. the dramatic shocks, shakes, rattles, rolls, and drops of everyday life/transport/usage? lots of people strap ipods to themselves while aggressively working out and have no problems.

Notice on Palm's web site & marketing propaganda for the TX they say "The look is timeless" or something similar? That's their way of saying "look how many T|E derivatives we've forced down your throats. What was once the cheapest Tungsten is now masquerading as their flagship PDA (I'm talking about casing/styling, guys, not specs).

No, greed, arrogance and laziness (mostly greed) are the only reasons for the elimination of previously standard features (cahrge LED, VR, vibrating alarm, metal body, G1, cradle).

I got my 2nd T3 *NEW* for $339 new at BB in early '04. There's simply no reason they could sell it profitably at that price point then and something as cheap'n shoddy as the TX is still $300 MSRP nowadays. Palm is making GOOD margins on these things...if they are not then it's something they are doing wrong on their end. The tooling/CAD/R&D costs on something like a TX should have all been amortized by this point, aside from the continued hacking/tweaking/fixing of VM/Blazer/FrankenGarnet. Basically, the TX likely cost them more in terms of software work/testing/marketing than any part of its hardware did.

Gekko is spot on. These portable drives are designed to withstand a lot. And even if there was concern then there is no reason why they could not have software routine to ensure the drive was parked before initiating the vibration.

I have started to think a little more laterally regarding the vib alarm though. The main reason for it (for me) is when I switch device to silent in a meeting. Not to be notified during the meeting but for when I forget to switch the sound back on after.

How about a utility to switch to silent for a specified time period (length of meeting + some) then automatically switch it back on. Hey it could even sound an alarm at the end of the time if any alarms triped while in silent mode.

Is there something that can already do this (ive not checked yet)? or maybe it would be a good first project to learn about palmOS software development ;-)

As bogus as the NTP patents are, ordinarily I'd be outraged if the Supreme Court refuses to review the case + RIM ultimately loses. But this is Lawsuits In Motion we're talking about. I hope Gates lends NTP a few of his best Court Sharks and RIM gets fcuked up the a$$. Hard. With no lube. Mike Cane-style. A dead RIM sure would help Mr. Gates' Windows Mobile platform, wouldn't it...

I expect Palm to gradually fade away as they become uncompetitive with WinMob and Nokia phones. Losing PalmOS sealed Palm's fate and NetFrontLinux will turn PalmOS into a shell of its former self.

Gradually fading away? Didn't that start four years ago?

In all seriousness, and going slightly OT here, I have been putting a 2nd TX through its paces. I still think it's ENORMOUSLY underwhelming-again, regardless of the asking price or web prices in the ~$250 neighborhood.

FrankenGarnet is just CRIPPLED in its current execution, especially when asked (tasked?) to handle dual wireless & 320*480. How bad is it when you have two TXs or two LifeDrives side by side, BOTH totally "clean" from a hard reset and one crashes more often than the other or has strange quirks. I can see getting bad hardware batches but how do you get "bad" OS loads? Corrupt ROMs?

Remember, I consider a Palm's core functionality as its completely VIRGINAL out-of-the-box-state. If it's unstable/crash-prone with VersaMail/Blazer/Bluetooth then I write it off as a lost cause immediately since most Joe six-pack types don't even bother loading anything onto their Palms other than PIM data and a game or two.

Palm really needs to step up to the plate and ensure that their future handhelds/Treos (assuming there are any) are absolutely bulletproof in every way imaginable in their default, factory fresh states.

Just commenting on your previous post about the virgin devices and one crashing and another crashing more...

Something I noticed about Garnet when I reviewed teh Qool QDA-700 was that Garnet is a really bare OS. All of the major functionality and dang near everything that we appreciate about the PalmOS is a faction of Palm/Sony's massaging, and not PalmSource development. So much to the point that the PalmSOurce Mail and Webbrowser 2.0 clients absoutley sucked on the QDA. And aside from the included Launcher II (yes it included), the OS is very raw and cannot do much of anything. If anything, the QDA makes TVOR's point of PalmSource needing Palm and vice versa painfully clear.

For one reason or another, some programs, not all, but some programs tap a bit hard at the core OS a bit more than others. The added in networking abilities cause anything network based to be unstable by design. Yes, the Treo 600 is a heck of a marvel, and after 3 attempts, Handspring really did get it right. But at its core the PalmOS really did suck wind.

We get mad at Palm, and rightfully so, for taking features out of "new" devices. But for the most part, I dont see an OS that can handle even those features without some level of OS hacking. And while NO OS should be this unstable when programs are added, the lack of some type of approval system by PalmSource for its licensees for the hacks and bundled programs has made for just as bad an experience for us, as it is finding out things are in the OS that were left out. PalmSource didnt give a heavy enough hand to its licensees and therefore we have Garnet, which could have lasted until PalmLinux, dying an embarassing death.

What are these "virgin devices"? ;-O

And aside from the included Launcher II (yes it included), the OS is very raw and cannot do much of anything. If anything, the QDA makes TVOR's point of PalmSource needing Palm and vice versa painfully clear.

PalmSource lacked the resources to create a polished, fully-debugged OS. They couldn't even fix PalmOS 5. It shuld be painfully obvious by now to everyone here why PalmOS 6 (cobalt) failed and why PalmOS 7 (PalmLinux) was destined to arrive far too late to matter.

For one reason or another, some programs, not all, but some programs tap a bit hard at the core OS a bit more than others. The added in networking abilities cause anything network based to be unstable by design. Yes, the Treo 600 is a heck of a marvel, and after 3 attempts, Handspring really did get it right. But at its core the PalmOS really did suck wind.

I don't think it's fair to bash PalmOS 5. It was asked to do so much more than it rightfully should have been expected to accomplish that it's amazing the OS didn't blow up. Telephony and Wi-Fi implementations are not something PalmSource is particularly adept at dealing with. As usual, the problem was Palm/PalmSource chose to avoid evolving the OS until it was almost too late and then had to rush things in an emergency situation. Designing an OS under severe time constraints is not a good idea - especially whe the OS is pushing into territory that the company is unfamiliar with.

We get mad at Palm, and rightfully so, for taking features out of "new" devices. But for the most part, I dont see an OS that can handle even those features without some level of OS hacking. And while NO OS should be this unstable when programs are added, the lack of some type of approval system by PalmSource for its licensees for the hacks and bundled programs has made for just as bad an experience for us, as it is finding out things are in the OS that were left out. PalmSource didnt give a heavy enough hand to its licensees and therefore we have Garnet, which could have lasted until PalmLinux, dying an embarassing death.

Palm/PalmSource was in no position to limit licensee's ability to customize PalmOS since Palm/PalmSource was too lazy/incompetent to provide licensees with the features being customized in the first place.

Cobalt, the bogus Palm "split" and Palm's refusal to evolve the OS when Palms were selling like hotcakes are the three main reasons PalmOS collapsed. I still am shocked by how poorly-managed Palm was. When people find out the details of Palm's failure I guarantee they'll be amazed that the company lasted as long as it did.

Those three parts must have cost $100, because omitting them was the only way Palm could hit the $300 mark... Now where's that $100 LED...

Capacitor and resistor and mic all together cost me $9.99 in radioshack in the form of the cheapest wired headset for cellphones. Inside it already had the capacitor and resistor attached to the mic as needed and it was just a matter of tuning the resistor to desired sensitivity and connecting it all to the inside of the palm.

The hardest part was placement. Believe it or not there is very little space inside. i placed it in the only place it fit and coincidentally it is next to the hotsync port so it has a hole to the outside and thus no need for me to make any extra holes.

Well done dmitrygr!!!

Given that Palm must have known that they could have voice recording ability for around $5.00, they must think that it is a little wanted/needed feature. I disagree. Given two identical Palms except one with voice-record, I wouldn't hesitate to pay $20 or $30 extra bucks for the recordable one. Seems like a big misstep for Palm.

Again, absolutely awesome dmitrygr!!!

I know it's fun to play armchair quarterback, but what you people are missing here is that companies operate on a "return on investment" (ROI) principle. Let's say there's $3 of additional parts, and $2 per unit of additional support costs (lets face it, some additional number of people WILL need support for that feature) and you've just raised the cost by $5 on an item that probably has a 4:1 markup. This means that in order to maintain the same return on their capital, the palm TX, with voice recorder would require being priced at $319 instead of $299. Would I pay that? Absolutely. Would everyone? No.

In fact, I would venture to say they have sold an much higher number of units (than they would have) by virtue pricing this unit just UNDER $300 instead of just OVER $300. The Fact is, some number of people don't give a crap about a voice recorder. I DO give a crap about it, and I wish everyone else did too. If all consumers were like me they would sell more units at $319 with a voice recorder than at $299 without. But alas, all consumers are not like me. On the bright side palm is making a dirty ransom on this product, and will be alive and well to come out with my next palm in the near future--hopefully with a voice recorder!! :-)

Remember, the money to build and run a business is competing with the ROI it can get in other businesses. If money gets a better ROI elsewhere, it leaves and goes there instead.

What's odd is that so much energy nowadays is going into hacking back IN the stuff that Palms USED to have...

...And Palm is now making the innovator's job even tougher - by doing things like coding the Treo OS to limit it to 32MB chips! I can understand Palm's jealousy that amateur hobbyists seem to be able to fix so many problems and overlooks with their devices that seem insurmountable to them, but limiting the hobbiest's ability to do so is kinda whacky.

I have found the smallest of the MIC in Hong Kong for just about $2.5 (US$0.32cent), I guess the resistor is just about that price.

elchino18 @ 11/29/2005 10:19:20 AM # Q
My enticement for this VR integration confused me ( this is because I have not upgraded from my Zire72 to TX), so the RadioShack Headset comes with all the parts that you need, even the variable resistor and all.

Becuase I thought the resistor was the SM (surface Mount Type) that you have soldered into, and then you buy additional MIC + CAP and solder it as per your picture.

Am I right in the above?

DMitry, will the VOICE MEMO software work from my Z72 to the TX, due to you have suggested to get it from LD instead.

Anyone has a picture of this HeadSet Cracked apart showing all the necessary parts that are needed? Many thanks for the trouble!

no. keep capacitor constant and change resistor values till you get desired sensitivity. without a resistor alltogether it is WAY too sensitive and clips sound. so just find a value that works for you. for me 10 K_ohm worked. if you get a more sensitive mic you might need 20, if you get less sensitive you might need 5. try a few and see what works for you.

Ok, so I bought the headset at RS, cracked it open, removed the mic....

1. How do I "keep capacitor constant?" It's connected to the mic you stated previously so I'm not sure what I need to do other than solder it (the mic) into my TX.

2. How do I "change resistor values?" Again, the resistor is part of the mic assembly right? So how, physically, is it adjusted?

elchino, no one is using a variable resistor, they are just trying different resistors.

Of further inspection, I found that in the PIC dissection photos, the chip you highlighted has a large WM on it instead of a waveform. I found a chip in my E2 with the same logo (the small square chip to the upper-left of the headphone jack in my picture, although the logo didn't show up in my pic), but the connections coming off it are all different.

Yes, IM, I can see it now.

yes, i have a Z72 and I have opened it as well, but the chip does not look like the one on the TX and I can't find the resistor that the TX showed, and comparing it to the Z72 I cannot see this resistor thing (SM type) Surface-Mount type, taht is.

I can take a picture tonight and mail it to you to see if we have the same wavi form logo on the chip, but it is different from the TX....

I don't know how to post the picture of my Z72 showing all the guts here in PIC web...

Anyways, i am out to look for a MIC that similar to the one you have...

Here in HK, it is different I have a mini earset (those that you hang on your ears instead of on your head) but when opened I cannot find any resistor of any kind, just MIC and Earphone...

Strange, but no worry, I try to get a more expensive one...

But this cheap one really work but on PC... don't know if on TX will work or not...

Let me know if you have a TX to try it on... as I am waiting for upgrade from my Z72.... to a TX full screen and with WiFi, VR is a MUST in my PDA!

RE: Crippled Palm: Arise!
mikkoam @ 12/1/2005 7:14:37 AM # Q
I strongly belive that the keyword for Palm not implementing microphone to PDA models beginning from T5 is VoIP.

This suggestion is also backed up by the fact, that their WiFI card was modified not to work with Treo 650, even if it could be accomplished by modding.

As long as most of their main models do not have VoIP capabilities, there is no reason to think any VoIP developer (Skype for instance) would create standardized software for Palm devices. Microphone & Wifi enabled LifeDrive on other hand is marginal device in comparsion to Treo or T-series and developers are not willing to create software for just one device in mind.

Exact reason why things are like that can only be guessed, maby its operator wish to no compete with Treo line, maby Palm is developing something VoIP related that they wish to be used only on their future models.

Palm is now carrier-dependent and VoIP hurts carriers. Not A Good Thing. VoIP in non-Treo devices could also hurt Palm by decreasing demand for high-margin Treos.

Only problem is Palm can't stick its head in the sand and ignore VoIP - it's already here and it's being used on other mobile platforms. Palm is being left behind again in the technology race. I don't see any technical reasons that Garnet (PalmOS 5) devices could not handle VoIP if the hardware was up to the task, but it ain'y gonna happen until Palm doesn't have a choice. I find it interesting that the Nokia 770 Internet Tablet is supposed to have an update that will enable VoIP in a few months. With Skype currently running on a ton of Windows Mobile/PPC devices, Palm's strategy might end up backfiring on them. VoIP is going to be HUGE, and 2006 is the year it will start to become mainstream.

VoIP: slightly overrated (at this point)
freakout @ 12/2/2005 5:58:18 AM # Q
Here in Australia , internet access simply isn't fast enough or reliable enough anywhere, I think, for people to completely trust their phone calls to it.

If there's one thing people have come to expect from their phones, it's reliability. You pick it up, you dial, you talk. It just works. Computers and the internet don't. Oh sure, most of the time they work, but the number of computer crashes and internet outages I've experienced in my life (far, far too many to count) far outweighs the number of phone outages (once for our landline, zero so far for my mobile).

Especially in rural areas of Australia, internet access simply sucks. And it may never get better, especially if our government's plans to privatise Telstra (national phone company, owns all the landlines) goes ahead (a private company will not care at all 'cause there's just not enough money to be made in those areas). Strike one for VoIP here.

And mobile phone call rates here aren't very expensive. The trend now is to pay a prepaid amount of about fifty bucks and get a couple of hundred dollars worth of calls. It's very, very good value. And wi-fi isn't widespread enough (yet) to ensure reliable coverage anywhere.

I certainly believe that VoIP will become big, but I don't think it's going to be this year. Or even the one after that.

Then again, the pace of technology often surprises me...

That is called "the 5 9s" in the plain old telephone system world - 99.999% availability.

It is debateable whether such rigid uptime is really REALLY necessary but it is THE measure used by carriers out there.

=====

I do not remember when my tv/data cable connectivity was not there. It's almost certain, however that 99.999$ is way better than what it is (That's about 5+ minutes of outage per year, BTW).

Surur @ 12/2/2005 10:26:31 AM # Q
Ive recently moved my telephone service from the government incumbent to my small DSL provider, and thereby got a great discount on my DSL service. My wife was very concerned about the stability and availability of the landline, but I convinced her the 3 cellphones we have at home would be more than sufficient to cover us. She was right to be concerned, as Ive lost telephone service twice now, lasting at least 8 hours, in the last 4 months, but I sure enjoy my 8Mbits/second DSL line.

As long as you have your own redundancy you can do 99.999 for yourself.

The old thinking that you build a telecommunications system for the benefit of everybody has well and truly died. Now they're only built & run to turn a profit. A young boy died two years ago because of our telco's greed and ineptitude:

http://www.smh.com.au/articles/2003/06/24/1056449244747.html

It's for this reason mainly I expect a lot more dragging of feet when it comes to wi-fi/wi-max/whatever coverage in Australia. Sam Boulding is not the only COT (Casualty of Telstra). No want wants to build a system with complete coverage anymore, 'cause in a country like ours, where people can live kilometres apart in rural ares, there's no profits.

I think VoIP's future is as a complement to existing phone services, as you've pointed out, Surur. It'll *really* take off when your standard phone handsets can switch from a VoIP service to a landline/cellular connection without you noticing or having to do anything special.

Are the chip numbers between the different units the same and what are they?

Special Thanks to dmitry for this cool idea

I'm also wondering if there is a way to fix the god-awful hiss when listening thru the headphone jack!

Crippled Palm: Arise!

Yo Flatacat,

If you find a way, please let me know....

I also need to know if there is a way to lower or kill that high-tone hizzi sound coming out of my z72 screen, all Palm has it! but the Sony ones are the minimal of all, almost cannot hear this! not to mentioned the mp3 is perfect!

Regards,

-Nel

elchino18: warpSpeed form PalmPowerups will do that
flatacat : you need to use mic1 input

Great program!

Dmitry ,

would a eletrite microphone work on this circuit.
I thought in using this circuit instead of destroying a headset ;) :

| +5v
|
-
| |
| | 4,7 kohms
-
|--------| | --------> to codec MIC input
[ ] 100nF
[ ]eletrite MIC
|
| GND

Thanks,

bertoli

Just had a thought... What voltage does a tiny vibration motor need to operate? And what voltage does the Palm output to the speaker? Do you see where I'm getting at? I'd be willing to sacrifice sound alerts & mp3's to get my vibrating alarm back! And an added bonus - mp3's should still work thru the headphone jack...

Dmitry;

Do you have any idea why the TX & LifeDrive are crippled when trying to connect to CDMA (Verizon, Alltel, US Cellular) Bluetooth phones? The T5, T3, E2 and all earlier BT-enabled Palms work perfectly with such telephones (provided they have a BT DUN profile enabled or present of course).

Any chance you'd be able to take a crack at this issue (put the BT stack of the T5 onto the TX, for example)?

Pilot 1000-->Pilot 5000-->PalmPilot Pro-->IIIe-->Vx-->m505-->T|T-->T|T2-->T|C-->T|T3-->T|T5-->TX

RE: offer:
vwykchr @ 12/7/2005 1:19:35 PM # Q
If you manage to include a LED for indication of charging, then it's sold!

PS - how easy do you think it would be to increase the TX's ram to 256MB? Is the memory the same type as in the T5? Do you think it might be interchangable?

Groete/Greetings

Dmitry, thank you for above. Just wanted to know if warpspeed tends to decrease battery life? and that's without increasing any other apps speed, except Screen Noise...?

Since I have found that on my Z72 battery life doesn't last as usual when activated...

Please let me know. Regards.

ps. did you get to sell your Tricoder TX? ;-) that would have
been a sold device if sold here in HK in just seconds!
and if in minutes & with a few stocks, they would have been
SOLD OUT!!

mp3 hiss

Alpha143 @ 12/18/2005 12:01:26 AM # Q
Whenever I play mp3 or podcasts, I hear this unbearable hiss. What is wrong with it, what can I do to fix it? Do any of you have this problem? Or is mine just faulty?

Thanks

I think it would be interesting if one could make good quality recordings with the TX. I can use my cell phone to make quick voice notes when needed. Is it possible to just add a connector for an external mic. are the standard mics which are made for computers, MD-recorders and such compatible with the circuitry? Are there any other limitations for the voice quality above the microphone? I'd like to use the TX to replace my MD-recorder when dictating my personal stuff..

Hi Visavo,

Any joy finding and answer to your "Microphone In" question?

It would be great to know.

I know of an iPod product called 'Griffin italk' - but I understand it wont work with the TX.

A good question is whois going to make something like that for the TX, and ....

why, WHY is Dimitry selling his modified one?

Does anyone know of any solution to:

1. The microphone in question, external device or otherwise (like a 'griffin italk', that would work for a Palm TX)

2. To get Skype to work on a Palm TX


Thanks,

nTX

AdamaDBrown @ 12/30/2005 1:50:00 AM # Q
You can install a microphone if you follow the instructions Dimitry has laid out here. It requires some skill with electronics, though.

There's no chance of getting Skype to work on the TX. Even if you had a microphone, there's no Palm OS version of Skype, nor one in the works.

Any updates from anyone re: microphone in for the TX??



RE: Microphone In
nTX @ 1/1/2006 2:12:27 AM # Q
An external microphone in - I would like to keep my warrantee intact ;)

nTX

RE: Microphone In
AdamaDBrown @ 1/1/2006 3:27:13 AM # Q
Well, there's no chance of that with any kind of hardware modification, and there's no option for an external audio input through the docking connector or any other warranty-friendly means.

RE: Microphone In
nTX @ 1/1/2006 9:44:28 AM # Q
Ther is an external device for the ipod, called the 'Griffin italk' - which plugs into the ipod speaker jack and makes it an external microphone in. This device only works for teh ipod given the location of the power connection.

Do you know of any such device, or what could be done to create or modify such a device so it worked for the palm TX?

nTX

RE: Microphone In
AdamaDBrown @ 1/1/2006 12:59:44 PM # Q
No, there would have to be the preexisting circuitry for a microphone jack, which the TX doesn't have.

RE: Microphone In
nTX @ 1/1/2006 8:14:21 PM # Q
Thats interesting, coz the Griffin 'italk' device is designed for just that situation, when there is no hardware to do the microphone task.

Any thoughts from from anyone?

No actual microphone hardware, perhaps, but the device would still have to be capable of an audio input. The TX isn't without hardware modification.

Mi_An @ 1/9/2006 12:33:00 AM # Q
Brown:

The pinout for the multi-connector shows a mic-in pin, why can't that be used?

RE: Microphone In
AdamaDBrown @ 1/12/2006 11:41:40 AM # Q
Well, I've never seen a pinout that includes a microphone option in the connector. The multiconnector does have audio out to headphones or speakers, but as far as I'm aware, that's it. If the MC did have a mic-in option, you might be able to use that, but I'd have to see this pinout before I was convinced.

TX mic mod

eeleye @ 4/15/2007 2:44:35 PM # Q
Thank you, Dmitry, for the great soldering pics. On a bored Saturday, I followed your instructions, and wired a microphone into my TX. It works great. Instead of placing the mic in the bottom beside the hotsync port, however, I dremeled a hole up top in front, and placed the mic there. Right between the SD slot and the infrared lights. I think the result looks good enough that most people can't tell Palm didn't put the mic in at the factory.
Here's the picture of the result. The only difference is that the wires are routed inside to allow for a different mic placement.
