Prototype on stripboard for R2’s smoke machine circuit. Needs trimming a bit, but works nicely. I2c controlled, with a variable duration from 1 to 9 seconds. It’s running at about 6v to produce a decent amount of vapour, so don’t want it running too long and burn out the coil. May do a PCB for it with the relay on board, as it is a fairly generic device so could be useful for other things.

Base white coat done in a late night painting/sanding session. As it’s a replacement head for R2 it’s going to need some blue, just not sure on what design to do. Tempted with a thin line around at the layer shift (even tho it’s now hardly noticeable). But will need more. Radar eye will be blue, hp cowl too possibly. Time for a think….
