Fuck fuck fuck.


Fuckers. Especially the Darlingtons.

Oh well.

The Mitochondrion isn’t going to be at Kiwiburn. I think I could get the current version to stumble into life, but the next debugging step would involve taking it to pieces and fiddling with them. The way it’s made, this would be getting towards as much work as changing the design and rebuilding it properly. So, I’m going to do it properly. This will take a while.

But, doing this for the third time round should be much faster, coz I’m made many of the mistakes already, and learnt from them. Like: hardwiring batteries is dumb, surface mount soldering isn’t that hard, lead-free solder is not ideal, IDC connectors are awesome, and just coz you can do 0.25 mm wide copper tracks, doesn’t mean you should.

So plan is to have the Mark 3 working by the Juggling Festival, end of March. Also, you should go to the Juggling Festival. Put it in your diary. There will be hooping.

This did make me realise that I’m not doing this for Kiwiburn, I’m doing this for me. The new design should also reduce the chip count from 35 to 13, which is only going to make life easier. Still, you will have to put up with me grumbling about not having it there.

    1. Well, there’s other problems, but the extra oomph is alteratively raising the voltage high enough that the picaxe should work, and raising one battery pack temperature high enough that it nearly caught fire. Debugging the other problems is tricky in this situation.

      So, another approach is needed.

      Can I bring the kit back on friday at Fidel’s?
