I started this project quite a while ago, and it was an unlucky one — always when the parts arrived, I was in a bit of slump, busy with some urgent thing, travelling, or just simply burned out. So the progress was slow, and I only took it as far as assembling and soldering the whole thing — I didn't have the energy to actually write the software to test it.

And now I'm bringing it back from the dead, so to speak, to enter it in this contest, but... I can't find it. I clearly remember assembling the prototype, but it's not anywhere in my drawers or boxes. I found the un-assembled PCBs, so I could get another chip and start again, but I would much prefer not having to do that.

I guess I will need to do a proper cleanup of my workspace.
