You have two you've never used, while I have 20 week shipping delays for one unit ordered six months ago, and a heap of schematics and already-wired modules to plug into the GPIO sitting uselessly, and a head full of further designs yet.
Goodness. I need to go for a walk. This thread is threatening to get the best of me.
I feel bad for you. Where are you located? If it is in the continental US I'll send you mine. I installed debian on it and did nothing else due to other commitments. I really don't know when I'll have chance to start playing with it.
I couldn't ask you to send me your RPi. I've put all that stuff in a box under my workbench and moved on to new Arduino projects. Someday maybe my RPi will show up out of the blue and will be a nice surprise and I can pull that stuff back out, but if I got it tomorrow it would likely end up like yours. I've just moved on for now.
