Projects

Completed Projects

Name	Description	Images
Sliding Gloves	Heavy-Duty sliding gloves for downhill skateboarding. Made from leather welding gauntlets and 10mm nylon sheet. Nylon was attached by melting the reverse side with a blowtorch and pressing to the glove.
Bedside table	With integrated USB charging ports and mains sockets. Made fron oversize weathered timber for a 'Railyway sleeper' type effect.	Complete
Shoe & Skateboard Rack	4 staggered shoe shelves, rack for 6 skateboards and 2 hockey sticks.
Chopping Board	With gravy / crumb catching slot. Made from scrap timber.

Active Projects

Name	Description	Images
4 foot Floorstanding Loudspeakers	Hi-Fi Loudspeakers based around a 12" bass driver and a 5" Tweeter.	In Progress
Rotary Subwoofer	A complete redesign of the Thigpen TRW-17. A variable-pitch fan will create sound by oscillating the blade angle at the desired frequency. This will permit the speaker to produce sub-audible frequencies at very high sound pressure levels compared to a conventional cone driver. Amplification will be via an existing Quad 44 monoblock valve amplifier.	In Progress
Chip Amp	Power Audio Ampifier using LM3886 National Semiconductor Opamps.	In Progress
ErgoDox Keyboard	Mechanical Keyboard split into two halves for ergonomics.	In Progress
