This was the main project of the Mechanics & Electronics module at Loughborugh University in my final year. Despite being a piss poor module which came under fire from our entire cohort, the outcome was rather fun. The brief was to design a device that would automagically plunge an Aeropress coffee maker (with as much pizazz as possible).
The result was a voice activated, self-inverting, X winged plunger that used the inverted Aeropress brewing method. It’s even equipped with a surprisingly intelligent homing sequence in the case of power loss – or emergency shutdown in the face of imminent finger loss.
This was a group project, but since the teaching was so poor that no one else had any clue what was going on, I took the managerial role – having the most experience with electronics so far. Initially we each came up with a design, then chose our favourite to take forward to the manufacturing stage. We chose my design, so I was head of design/CAD, coding and final assembly/debugging. Izzy headed up machine learning and voice control. Bii and Taz wrote the bulk of the report and did a lot of the boring box ticking exercises needed to score marks – as well as manufacturing the laser and water jet cut parts. Big thanks to those guys for doing all the bits I didn’t want to do – you’re heroes.
