Project Ideas

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 current bike speed.

Success criteria:

  • generate some light at low speed
  • generate more light at high speed
  • get it too work
  • don't break the bank
Visible surge arrestor project I want to know when power surges happen, and if possible stop them cheaply and quickly. Project:Surge Arrestor
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

mirrored coils wild ass; might exist as a Common mode choke 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?
bike trailer sketches on envelopes to carry standard building 2.44 x 1.22 M sheets, 2up kayak, etc. Considering
  • extending the bike rack so the trailer can be carried inverted over the rack;
  • wheel mounts that can be pivoted to vary the trailers wheelbase
    • narrow for storage on bike
    • wider for normal use
    • extra wide to control the windage of a building sheet
