Here is how to use an Evo T20 thin client as a stand alone Internet radio receiver :

Why do it Well I did it for 3 reasons
1] because it was a challenge

2]To have a noiseless low consumption unit only 20 watts at peak rather than run a noisey power hungry Full Desktop PC ( I have measured mine and once Booted uses 8 Watts)

3]To find a use for something that otherwise was junk -

These older thin clients are currently getting pulled out of many businesses and can be picked up for anything from a few dollars to $50 dependant on how lucky you are. Have a look on Ebay or better still in the Dumpster out the back of a Network Dealer. Once fully configered no Screen key Board or Mouse is needed - Simply press the on button and after the 2 minutes of booting - Audio of your favorite Internet radio station comes out of the 3.5mm stereo plug ready for headphones or a suitable amplifier - Once you have finished press and hold the same button and the unit turns itself off

To Make things easier a Networked computer on the same Network with a "Shared" directory as a place to store files in the build stage helps, as does an extra mouse keyboard and monitor. The networked computer needs to be running Windows 2000, XP or Vista I do not Know about 7 yet!! There is a way round this using a pendrive which I have posted here http://www.instructables.com/id/Adding-Memory-to-an-EVO-T20-with-NT4e-to-make-a-u/

Step 1: First Buy Your EVO T20

Not all Evo T20 thin clients are the same some are quite high specificationed and some are basically Junk - To do this you Need one of them that Runs Windows Nt4e or Windows XPe with enough flash memory basically the 64 megabyte or better . The Windows Ce ones are totally unsuitable for this Project and are basically a Door stop: They all look the same and use the same 5 volt 4 amp power supply the only way to tell them apart is by the part number ; This is located underneath the unit. Other Thin Clients that I have tested and work are the Compaq EVO T30 Thin Client and for the Ultimate Version the " Hp T5700 which can be used as a Video Host".

Fortunately lots of information is available online at the HP web site and other sources http://h18000.www1.hp.com/products/quickspecs/10865_div/10865_div.HTML
The following Part numbers are the ones it should work on from the HP list
305253-xxx 308791-xxx 311334-xxx

306480-001 is what I have used (128megs of ram and 128meg of flash ) in the demo After several trials any T20 or T30 with 64 megs or more is a possible candidate. With a 64 meg flash you have the options to source a 32 Meg smart media card ( if you can find one ) - slip that into the socket on the EVO's mother board then reflash it as a 96 Meg unit.I have found no way of making a Ce Unit into a NTe. With Windows media player installed a 64meg flash unit still has 9megs of spare space
You will also need a USB mouse a USB key board and a VGA monitor and Wired Internet (a Rj45 cable feeding broadband Internet From a router Ideally set in DHCP mode to give out network Ip addresses)
I've been able to do quite a bit with my 48/96 ( now a 48/192 with optional usb flash drive). Mine has Sonique as its media player. I also installed an old copy of Mozilla Firebird, the Windows 3.1 Best of Windows Entertainment Pack, Solitaire, Frecell, and probably the coolest two programs are Mini vMac and WinQuake, all on the flash stick. The NTe T20s are surprisingly versatile little machines.
Great to Hear that as they use so little current and are cilent I find that to do small simple tasks much better than starting a fully optioned computer
Excellent project.&nbsp; I have a lot of thin clients floating around, with the intention of doing something like this.&nbsp; But, alas, I am always at a loss for time.&nbsp; This is one that I might actually take the time to do.&nbsp; Pandora over the whole-house audio, here I come.<br />
Glad to hear My Idea is being used : Have a few other none standard uses for these machines they make great network printer adaptors so you can use cheap USB printers&nbsp;and anyone can print to them across the network basically converting them into Ethernet printers which normally cost&nbsp;$100+ more - Also have managed to make&nbsp; a T30&nbsp;into a&nbsp;Programmable Stream recorder to record my favorite overseas&nbsp;Internet radio and to play it back when I&nbsp;want it ! &nbsp;
If you installed a Windows version with Remote Control Desktop included, you can control the Thin Client around the home. I have a old iMac G3 and i'm planning to make it a second monitor for Virtual PC, Remote Control Desktop and any other thing i need a second desktop for.
Which Thin client are you working with ?
Good ol' HP/Compaq T5500 i believe, or one out of the family. It comes with Windows CE for VPC itself, but it's able of USB booting, and i guess Windows 98 should work fine on it. Also, my plan has changed, i will make this my Media PC for games and TV. Than i don't need to extend my Coax cable for a few meter in my room. And i can play Petz 5 and 4 on the TV :3
Only Issue I can think of is are they generic mice with just the 2 buttons and maybe a single scroll wheel or very &nbsp;fancy multi button mice[ Usb Ports are class 1.1 I believe and&nbsp;so some modern equipment is not compatible ]&nbsp;- Never had issues with any generic &nbsp;mice in any of th3 T20s I have used -Would suggest trying a new cheap&nbsp; generic mouse first ?&nbsp;&nbsp;Is a key board working- If&nbsp;a key board is working suggests USB ports are good &nbsp;first thing I would do is reset back to factory settings in case &quot;&nbsp;mouse function&quot; has been turned off - press and hold G when doing a restart while the Led is still amber - if that fails then may need to do a full&nbsp;reflash back to the factory setting - or possibly the T20 unit is faulty?&nbsp; Hope that helps
I buyed a brandnew USB-keyboard from Konig and plugged in a USB mouse, works fine in BIOS.
Hmmm my evos wont boot onto a desktop, they keep booting into the Compaq Connections Manager, and I cannot seem to connect to anything from there, (well i have no terminal server) :(
Connect a USB drive with a Windows Pre-installed enviorment, or connect a Laptop HDD if possible.
The Higher spec T5500 will allow connection of Laptop IDe Hard drives or CF drives in a Laptop Ide adaptor internally and happily access a USB memory stick they will access a USB stick in the preboot stage as that is how you re flash them - (however it is expecting to see the standard flash image and you would probably need to modify that rather than just pulg in a Pre Install enviroment of your choice and hope.) The T20 and T30 units just expect to see mice and keyboards and ignor USB memory sticks
USB is not the most friendly way. Here's a list why:<br>Windows 2000 - INACCESSABLE BOOT DEVICE<br>Windows XP - Reboot loop, no safe mode will get around it.<br>Windows 95 - Does not do anything, it goes to network boot<br>BartPE - ERROR 16<br><br>That didn't work that well.
One thing that will sometimes get it out of this logic Loop is to Turn it on without any Ethernet cable plugged in some times it wont start the logon sequence then - if it has been extensively changed from factory " flash " might need reflashing before you can do anything - Important question look on bottom on silver bracket what is the Part number on sticker !
I picked up a HP Thin Client (T5500) on a secondhand shop for 9 Euro! They had a big load of them, and they had other Network PC's. So yes, they get pulled out of offices, but they are NOT useless!
hey, i bet this could also make a nice intercom system.
I am trying do do internet radio on a T20 - but the one I got off ebay, neither of the usb mice that work on my other computer work on the T20. Do you have any tips?<br />
Hmmm This sounds like something I might have to do, acutally I was planning on building something like this and running it over my extra pair of wires in my home network, then I can have internet radio everywhere!!! LOL, I just ordered Three thin clients on ebay, they still have their original boxes keyboards and mouses and everything, I am soo excited........
Cool ible. I've had the guts of one of these sitting in a nice wood box acting as a juke box. It net boots Linux and runs mpd, these are just powerful enough to be useful.
Yes Good project .I have managed to get one similar but booting from the Flash Image- the Songs on a pen drive and remote network access to change songs Amazing little computers really .
