[Rik]’s Hexastorm laser scanner mission initially used a discrete polygon mirror controller+motor module from Sharp to spin a prism. However the scanner head was a bit troublesome to assemble and had lots of messy wires. This has all been changed by a single board that includes a PCB-printed motor, primarily based on the work of [Carl Bugeja]. The outcomes are promising up to now — see video under the break.

Because the prism will not be hooked up to something, at present it’ll fall off if mounted within the supposed vertical orientation. Considered one of [Rik]’s subsequent steps is to enhance the mount’s design to constrain the spinning prism. The earlier Sharp motor was specified to 21000 RPM, however was solely pushed to 2400 RPM in [Rik]’s first model. This new PCB motor spins at 2000 RPM in these exams, similar to his earlier experiments ( we’re undecided concerning the most RPM ).
