Things I've Built

Electronic Dummy-launcher

An adapted Coil-gun, meant to accelerate a Nd-magnet by subsequent powering of 15 coils. The result should be to shoot away the payload with 20m/s in a ballistic track to come down >>30m from the gun. Stalled for unknown time.

CCDpos

This high precision (sub um) displacement sensor with a range of 14mm is build with a small diode-laser, a 90 degree prism, a TCD1304 linear CCD and a STM32F401CCU (blackpill) MCU. Readout + analysis is done on a PC.
