Let The Conductive Chaos Continue
Some "Are you OK?" messages in my inbox. So yes, I am, for given values of OK. I have a commission to fulfil, which got reduced in time by 70% so am in flat panic mode doing little else.
On the μRepRap front, I've been totally unable to secure conductive resin. This means most other people won't either, so a DIY approach may be necessary. I'm looking at two approaches:
1. Source some PEDOT from Asia and mix my own using standard UV resin. In theory I can make something that will work. However, the stuff is expensive, and other reagents are needed which may be illegal in some jurisdictions, so convenient synthesis may have to be developed too.
2. Good ol' graphite. Unfortunately the graphite dust available at hardware stores is somewhat chunky on the scale that μRepRap works on. It may be possible to put it in an ultrasonic cleaner and break it down to smaller particles.
Sadly, no time to play. If anyone else wants to have a go, please do.
