| Project | Status | Notes |
| Reconfigurable sailing proa | mostly inactive, built small bits | Rob Denny at http://www.harryproa.com has some interesting things to say about Proas and how they could be the basis for a cheap, high performance, spacious sailing cruising boat. Perhaps the ideal cruising boat :). I want to explore the sailing characteristics in a model. |
| LED lights and lenses for my bike | active | http://pilom.com/BicycleElectronics/DynamoCircuits.htm explains the matching of LEDs to bike generators. I plan to have several strings of LEDs with different beam angles and aiming points - and the appropriate string of LEDs turned on for the curent bike speed.
Success criteria:
|
| Low viscosity blood | thoughts | I have some more reading to do; but am intrigued by http://customers.hbci.com/~wenonah/new/mcdaniel.htm and http://en.wikipedia.org/wiki/Integrated_Pulmonary_Index |
| Make solar cell? | idea | Link http://www.freewebs.com/acselectronics/TiO2solar.html |
| Safe by design nuclear | meme | 2 hour promo |
| Money acceptor | idea | link the following up to the central credit server RFID tool control - a RFID reader for your ID, a camera, a computer, some reference images, an input tray, a money vault, message window (i think that is £2.00 - will you accept £2.00 credit for it?) or (i think that is 10.50 USD, will you accept £3.76 credit for it?) or (i think that is a bottle cap, will you accept a £0.02 charge to dispose of it)
and servos to shake the tray for better images, flip the tray over to accept money or dispose of trash. Given we had software that recognized stuff in sink, is it a big leap to recognize images on a tray? |
| mirrored coils | wild ass | wind two coils on the same core, one left hand the other right hand and link them together. I think they should act as a filter of some sort, because the emf generated by the first travels faster than the electrons and reinforces the current in the other coil, smoothing out the edges of each pulse. The filter frequency being related to the speed of light and electrons in copper and the coil winding length. Maybe there would be less energy lost in the filter? |
