• Prototype 2, the DIY way

  PixJuan • 09/03/2022 at 05:41 • 0 comments

  At first I was thinking about another way of building my Cyclo-Greenhouse, much DIY, that would be more in Hack-A-Day spirit.

  Prototype 1 would be the safe way of testing the concept, prototype 2 would the fun way!

  It would be more interesting to build a prototype from scratch, and smart people have already tried to build pedal-powered things :

  And this one is exactly what I am trying to achieve

  The idea is to either build a frame or reuse a vintage exercise bike and build a generator and converter.

  the idea is to reuse a vintage flywheel exercise bike, but to put an old electric bike wheel on it and generate electricity with it.

  Constraints for the prototype
  

  • Not dangerous (no unprotected flywheel with spokes) if it is to be left in a school

  • Be within my time budget (not big for the moment)

  frame
     either an old stationary cycle where I could fit a generator, or  a few soldered tubes, a seat and a handle bar. We need a handle bar to properly cycle.

  generator
     https://www.k-tor.com/shop/generators/power-box-50/
     this pedal powered generator can directly charge a 12V lead battery, it is the simplest solution
  battery
     classic car lead battery
  greenhouse
  

  There the greenhouse itself, Ideally I would take a proper one with real glass, but it's too big an investment before being sure the concept works.

  lighting
  

  Concerning the LED system it looks like I need to have different kind of leds one to make the plants grow and another to get flowers.

  water

  A system to water the plant may be required, otherwise a human intervention is needed.
  I don't think I will use hydroponics, but it remains an option.
  

  heating
  

  I suppose a heating system is required to prevent the plants from freezing (and maybe to better simulate the summer)
