Okay, time to spew my brainstew about bike things.
I bought a 1955 Schwinn traveler and spent most of this morning cleaning it and inspecting it. It has a small generator that powers a two lights, a tail light and a headlight. It is great because now I don't have to buy a light for night riding. So, naturally I wouldn't be using the lights during the day so i have all that extra power to use. The plan as it is in my brain is this:
Biking during the day supplies power to a battery which then can later be switched to power LED lights for night riding. Also, the battery would power a odometer and speedometer. More on how those would work later. This would involve wiring the power from the generator into a battery circuit. Then have a switch for the LEDs to turn on.
How would a DIY odometer work you ask. Well the most basic way that I have at the moment is using a calculator.You press + 3 (assuming 3ft is the cicumfrence of your bikes tire). then using a reed switch and some soldering, make it so the bike presses = every time your bike tire rotates once. this adds 3 to the total. So eventually you get where your going and you have how many ft you biked. If you want, you can use the MR+ button to store your mileage until next trip.
More on how to make a spedometer when i figure it out.
