Spent most of today creating inventory templates for workshop stock. After unexpectedly running out of materials yesterday, I’ve realised I need to manage it all much more actively.

I also have an order of electronic sundries on their way to me, including some Darlington transistor arrays and stepper-driver ICs. This should be enough to get prototyping of the Bonsai Repstrap to the next stage.
Comparing the price of dedicated driver ICs, I’m wondering if I couldn’t make quite a saving (on cost and part-count) by using a Sanguino rather than direct Paralell-port control.
The Reprap still uses stepper driver ICs as well, but could a Sanguino drive the Darlington array directly? It sounds like it would have enough processing power spare to manage the sequencing.

Anyway, time to see how the castings are doing in the heated cabinet, and get some inventory done.
