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. |

|---|---|---|---|---|
| 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. |

| 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. | |||
