You wait for a bus

Then three come along at once.

I was showing my partner progress with the Time Machine at the weekend and it suddenly died.

As expected when I looked tonight this was down to crappy power distribution, something had come loose.

It's been obvious for a while that I need to sort this out so I'd already ordered some busbars to do it. For the wire gauges and amount of current involved they're OTT but they are nice and tidy.

I also suspect the tiny switched mode DC to DC converter I bought to generate 5V has died. Most of this runs off 12V and the Arduino makes 5V for the odd bit like the remote control but it's not enough current to power all those servos.
