I have been awful about keeping up with x0xb0x news as I am wrapping up the next run of x0xen (panels came in this week, yeah!) But I am completely stunned by this incredible x0xb0x casemod:
In fact I am so utterly entranced, I won’t say a thing about it. Just get your ass over to the website and order one of the limited editions. Is open source hardware awesome or WHAT?
If you have an Arduino project where the dev board is stuck inside a machine, or attached to the rafters or is inaccessible in some other way, a wireless programming/debugging link will save you tons of time. This tutorial is an extension on Rob’s version. In this version, no extra firmware or hardware (other than a capacitor) is necessary. Just use the default bootloader. I demonstrate it with a ‘classic’ Arduino but of course this can be easily adapted to any version or clone.
You will need 2 XBee adapter kits, 2 matching-protocol XBee modules, an FTDI cable (or other FTDI breakout board, if you can wire it up correctly) and a 0.1uF capacitor (although sometimes a 1.0uF capacitor worked better)
The big trick is turning on “Digital I/O passing” where the reset pin is wirelessly mirrored from one XBee to the other. I spent a few hours reading the datasheet to figure it out!
Check out this diagram, can you tell I spent 5 minutes on it?

I just wrapped up a little step-by-step on turning an FTDI cable into a Parallax Propeller programmer. The instructions can be applied to any FTDI breakout board, might be handy if you have a Propeller but no propplug kicking around.
