We brainstormed some ideas and came up with the following :
- Triggering : use a windshield wiper control - it already does variable speeds and allows for arbitrary delays. Most of these systems require 12V, which may be more than the motor for the mister needs, so regulation would be required. I suggested perhaps an optical sensor, but that requires extra circuitry. I suggested we start off with a simple switch and work up from there.
- Power : I suggested a rechargeable battery pack. Eric's SO Jenny suggested a generator which would require attachment to the bike. Perhaps solar? Again, I'm thinking start with a battery (like for a portable DVD player)
- Mounting : probably attach to the handlebars. If we used a bike water bottle, perhaps any existing water bottle holders could be used.
- Spray nozzle : I suggested a tube connected to a flexible stalk. If the water bottle holder was close enough to the handlebar, then everything could be attached to the water bottle
