Hi,
Do you have any tips on where I should buy the parts for the USB-IR toy ? Especially the TSOP38238 IR receiver and the TSAL5300 IR emitter ?
seeed-studio and Gotronic don't have these components,
Farnell and Radiospares are too expensive for a single person.
Could you give me other references of IR LED an receiver which should work as well ? (I think any IR LED will do it... like this one : http://www.seeedstudio.com/depot/origin ... Path=32_28 (http://www.seeedstudio.com/depot/original-osram-ir-led-sfh485p-p-69.html?cPath=32_28) .. Am I wrong ?)
Thanks

Or 4 posts below yours.
Start with Mouser, they are excellent, can't say the same of others (-> Newark, although they look too similar).
Thanks liyin
Yes I went through this topic (I found the ref for IR emitter and receiver in your parts list!)
Mouser seems good, but delivery charge is 30USD (except for orders over 100USD), which is really too high for me!
Newark ships in US only and I'm currently in France...
International parts ordering is difficult. There are some chips which cannot be exported from the U.S. without special permission. For that matter, there are even chips that are available in every country EXCEPT the U.S. One of my clients has to order their regulator from Canada or the U.K.
For your sake, I hope there are hobbyists in France who can help you find a local source. I'm not certain, but I really doubt you'll find cheap shipping from U.S. sources for this kind of commercial parts supply.
Mouser is also useful for finding substitute parts.
I think any 38KHz IR receiver module for remote control applications could be used. These are the IR receivers you'll find in several IR circuits on the net:
TSOP1738, TSOP2238, TSOP38238
TSOP17xx => TSOP1838 => TSOP11xx (xx KHz)
SFH506-xx => SFH5110-xx => SFH5111-xx (xx KHz)
You can check the datasheets of these parts for possible substitutes, sometimes differences among them are small.
Its looks like you might have it under contol here.
Any IR LED with work, and any *modern* IR receiver centered on 38khz will work. By modern, I mean with an internal pull-up resistor. Really old receivers needed an external pull-up, but most new ones have an internal resistor.
Here's a place in germany (with english and french pages) that sells the approximate LED I used in the IR Toy prototype (instead of the funky LED used by Seeed - again, my fault):

Thanks all,
I'll try the IR receiver from Seeedstudio : http://www.seeedstudio.com/depot/infrar ... p-104.html (http://www.seeedstudio.com/depot/infrared-remote-control-receiver-module-wo-steel-shield-p-104.html)
with the LED ian suggested.
btw the IR receiver ref (IRL106A2B) seems strange to me (I cannot find it elsewhere)... but according to the description it should be good.
I saw this reference to that part [here] (http://http://www.mikrocontroller.net/attachment/76143/parts.txt):
TSOP TSOP1738, TSOP1736, SFH5110, no-name ones also worked fine for me (http://www.seeedstudio.com/depot/infrar ... Path=32_28 (http://www.seeedstudio.com/depot/infrared-remote-control-receiver-module-wo-steel-shield-p-104.html?cPath=32_28))
I tried the receiver from seeedstudio with the LEDs from www.led1.de (http://www.led1.de), and it works perfectly.
Thank you!!
By the way, I made my own version of the USB IR Toy, you can see it here : http://rousselmanu.free.fr/articles.php?lng=fr&pg=110 (http://rousselmanu.free.fr/articles.php?lng=fr&pg=110)
Looks nice, did you make the PCB?
I get 12 DRC errors in ARES.

@liyin: Yes, I made the PCB, as you can see on the pictures!
Yes there are some DRC errors. 6 of them are because of the 4 holes on the corners (to fit in the case) and because I wanted the USB connector to be aligned with the edge of the case.
You can just don't care about these 12 errors: I had no problem when I made the PCB.
This is the version I used, but I think I'll modify it slightly to be more "professional" soon..
