I felt that the battery powered Bluetooth speaker I made could be improved with more colour! Taking a leaf from the VU meters on amplifiers of the 80s, I decided it would be neat to sandwich clear acrylic between the plywood layers, each with an integrated LED that would form a full body amplitude meter.

I wanted to create a special birthday present for my girlfriend, whom had no speaker system. I decided a battery powered Bluetooth speaker would be neat, and having just learnt use of the laser cutter I came up with a layered design. The internals consist of a 2x15W RMS digital amp, 2x15W 80 cones, a […]

I was assigned design of the gliding sub-system (a long-range AUV it had to optimise energy use) and was also the business […]
