Reconfigurable sailing proa plan 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 plan 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:

  • generate some light at low speed
  • generate more light at high speed
  • get it too work
  • dont break the bank
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

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?
