    End of Life: Scheduled for obsolescence and will be discontinued by the supplier.
    Atmel is going to discontinue the usb key sooner or later, but I think the sudden demand for their module is going to make them reconsider

    Oh wait, nevermind, they are all sold out, you can though just buy a SMD to DIP board and an avr with hardware usb. It should be much cheaper and if you want to get into AVR programming, you already have a nice setup

    http://uk.farnell.com/atmel/at90usbkey/evaluation-kit-avr-usb/dp/1455078 UK link.

    For Europeans or people in Asia, you can use farnell for buying your avr's. If you need a board NOW, just get a soldering iron, some solder and flux, a breadboard, a SMD to DIP adapter, an old USB cable, and a crystal, I will work on making a list for people interested.
    i'm interested and would love some more info. i've got a soldering iron and solder still and know how to use them and would much rather give it a go myself then bother farting around finding someone that has a board in stock.

    i'm in australia and its hard as to find anywhere that sells these, and most places that do charge more then the jailbreak dongle would cost lol

    There expecting new stock come the 10th. Also there based in the UK so quids in
    Thanks, its also cheaper then the Farnell's board.

    I'm wondering the same thing. Looks like it will cost about 10$ and an hour of solder fumes to build this... just need to know how to flash it, and if the code released is compatible with this the Atmega164PA.

    +1 for this

    I'd rather build my own!

    yeah its confirmed working on the AT90USB162 right?

    if so i can just get one of these http://au.farnell.com/atmel/at90usb162-16au/avr-usb-mcu-16k-flash-smd-tqfp32/dp/1455073 right?

    then just need some solder and a way to flash it with the hex code and then solder on the usb cable?

    Aye, you can get the ic's from octopoart.com

    For example, the AT90USB162 you can type into the site and when you click the first link (always go for the first link) you will see this.

    http://octopart.com/at90usb162-16au-atmel-5836169

    Choose any supplier, it lists suppliers in the states as well as Europe and Asia.
    As an example I picked Farnell, which gave me this.

    http://uk.farnell.com/jsp/displayProduct.jsp?sku=1455073&action=view&CMP=GRHB-OCTOPART-1000082

    The problem with just getting the ic's is that you need a programmer to flash it, you can get one from sparkfun for not too cheap.

    Some distributers will flash the chip for you if you send them the .hex, which is shared from the guy who made this open source, but I have not seen such a company doing that for small <100's units.

    So now you have the IC, you need a crystal and USB cable. The crystal you can get from farnel as well.

    You need a 16 MHZ crystal. You can desolder a 16mhz crystal from something you already have, such as a remote control or anything of the sort if you are REALLY cheap

    http://uk.farnell.com/iqd-frequency-products/lf-x355a/crystal-oscillator-16mhz/dp/9712526
    or
    http://www.sparkfun.com/commerce/product_info.php?products_id=536

    You should use a breadboard, which you can get from radioshack for a few bucks.

    You can get a 5volt voltage regulator from RS as well if you want to power the jig from some outer source such as a wall wart, or you can power it from the USB Vcc from the ps3.

    The SMD to DIP adapter is a PITA, you can get one from:
    http://www.proto-advantage.com/store/product_info.php?products_id=2200117

    The ic's are .8 pitch and 64 pins from what I see, so stick with that one. You can solder magnet wires to the ic and not use a SMD adapter, but you need very steady hands, good lighting, a good tip, and a hell of a lot of luck/skill

    All in all, this is more expensive than the JIG when you count together the shipping, but if you have some of these parts already, which I guess you do, such as the crystal and breadboard, then it should break even.

    Best of luck!

    this is a doc containing the specs for the AT90USBKEY very nice diagram of the hardware... if you wish to build your own i would suggest using these schematics...

    Yes, just take any ole USB cable, cut the connector that is NOT type A (cut the end of cable that does not fit into your computer) and strip the wires and wire them up to the IC/bread board

    I said in the earlier post about soldering it, you can get that SMD adapter and stick it onto your breadboard.

    The programming might be difficult, but you can make one if you have a parallel port in your computer or if you want to buy more ic's you can make one yourself Though I would recommend buying a programmer for someone just starting out with microcontrollers.

    awesome man thanks for all your help.

    i'm really thinking i want to give this a try the only thing stopping me at this point is being able to programme the chip. if i can't find someone to do it for me its going to be a pain cause the programmers themselves are fairly expensive over here and it would be better off just buying the board for $50.

    but i can get a cheap breadboard from dicksmiths for $2, the chip for $5 and the crystal for cheap as well so might be worth it and would be more fun

    Anyone know if one of thse will work Arduino Nano V3.0 (ATmega328)

    http://cgi.ebay.co.uk/New-Arduino-Nano-V3-0-ATmega328-D-Robotics-UK-/130420360016?pt=UK_BOI_Electrical_Components_Supplies_ET

    Thanks
