Found a lovely old calculator whilst in a second hand shop. The case was broken so I thought I’d make it a nice colourless acrylic case so you can see the internals. Check the vintage display and PCB traces!

Can’t beat having a physical calculator to hand, even if it is relatively simple.

Continued electric skateboard motor build photos: here we are glueing magnets into the bell. Magnets ordered from http://www.supermagnete.de/eng/

Magnet spacers were traced from plans designed at http://www.gobrushless.com/ 

Thinking that http://supermagnete.de may be my new favourite magnet supplier - look at the goodies, including tiny packet of German Haribo bears!

Weekend collection

Scott Towler is building me a 3 phase motor to put on a skateboard. Outer bell turned from found object pipe. Bearings recycled from original donor brushless motor. Small bearing: 6mm inner diameter, 17mm outer. Larger 35mm inner 55mm outer. Aluminium bearing bush 58.3mm outer diameter.

A breakthrough on the continued development of the drawing robot / polargraph kits I’ve been working on, alongside Matthew Venn and Sandy Noble. We had tried several different ways of attaching the reels / spindles to the smooth shafts of the stepper motors we’ve been using:

- friction / push fit directly onto the shaft: hard to achieve, depends on fine tolerance of laser cutter, eventually starts slipping under load / over time

- a clamping technique using two laser cut pieces to ‘sandwich’ the stepper shaft and bolts to drive the reels / spindles: this worked but seemed hugely over-engineered for the job.

We feel this captive nut solution is a touch more elegant and will be running some tests…
