I'm Seb. Day job involves mechanical design on jet engines, and figuring out what screwed up first when an engine decides to melt a bearing or spit blades all over the floor.

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.
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.
AI Lens conversion for Nikkor-H 300mm Telephoto lens.	Includes aperture coupling slot as well as minimum aperture slot for compatibility with newer digital bodies.

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.
Rotary Subwoofer
Chip Amp	Power Audio Ampifier using LM3886 National Semiconductor Opamps.	In Progress
ErgoDox Keyboard	Mechanical Keyboard split into two halves for ergonomics.	In Progress
Tilt-Shift Lens	To fit a 35mm Nikon SLR camera. Will use an existing Mamiya-Sekor C 45mm f2.8 Lens. This medium format lens has increased coverage compared to a 35mm lens to allow for movements relative to the image area.
Hackspace Wire Rack	Needs more broomhandles and caps on the end of the rack, plus labeling.
LED Skateboard Deck	Taken an old cruiser board, drilled around 400 holes and fitted blue hi-bri LEDs pointing downwards.
TV Table	Including shelf space for various consoles, HTPC and an amplifier.
LED Lamp	With spare LEDs from the Skateboard deck, a high-voltage linear circuit to power 300 LEDs at 50mA each.
