A StickDuino shield Adapter

Why has nothing like this been made yet? this adapter I'm working on will allow a StickDuino to accept any standard Arduino Shield.

I'm wondering if cross talk will be a problem on the digital pins though? add a

add a battery pack http://www.liquidware.com/shop/show/BP/Lithium+Backpack+Stealth then a gps shield http://www.ladyada.net/make/gpsshield/ and you have one sweet setup that you can plug easily into any computer

I honestly didn't know how much demand there'd be for a stickduino sheild. I didn't expect the "small USB stick sized" crowd and the "shield prototyping" crowd to overlap much.

A few quick ideas though: - Cross talk shouldn't bee too much a concern at the speeds the Arduino switches at. Outputs are also usually driven against less than 10K of output impedance. - The 3 VCC pins are only present on original stickduinos, recent stickduinos have "VCC, RESET, and GND" in the top left instead. - With all the board space available, you could add a prototype area or a small boost converter. - The Stickduino has 17 pins/side. Unfortunately, 17 pin female headers are basically non-existent. You might consider using two 16-pin headers and just ignoring the extra ground on the lower right and the extra VCC on the upper left.

Feel free to hit me up for some collaboration.

I agree it's a niche item, but the design seems simple enough, if you want to make homebrew PCBs... it's good practice.

Unfortunately, 17 pin female headers are basically non-existent.

Buy the 40-pin headers, and snip them down. With the male "breakaway" headers, you just snap them in between the pins and you don't lose anything. With the female headers, you snip your way through the middle of a hole with your angle-snips, and you lose that hole. You can then trim the snipped rough edges down if you like. You can get two 17-pins and a 4-pin header out of a single 40-pin stick.

I don't see the use for this. In my case, I bought my iDuino after I had a couple of Diecimila's, so if I want to use a shield I use the standard board.

But in general some arduino/freeduino variant isn't that expensive. How much will you really save by buying/building an adaptor instead of just a second Arduino?
