I also have other ideas for projects I want to make. Many of them centering around cooling:
Also using a Peltier Module - cool grow "chamber"
For this, I intend to section off a small part of the balcony and cool it more dramatically using a combination of thermacol for insulation, evaporative cooling and two peltier modules (in this case given current and moving heat from one side to the other (and thus re-moving heat from the chamber). I have the equipment I need to make this. Matter of making it. I am useless at electrical wiring. If anyone can help, grateful.
Mini wind turbine from scrap bicycle wheels
Taping adjacent spokes of a bicycle wheel to create angled blades, taking out the bearings and attaching the wheel to a generator motor, which in turn attaches to a charge controller and whatever after that (did I mention I was useless with the electrical stuff?). The ball bearings part of the wheel could probably be repurposed to make a swivel mount, so that the gadget can always face the wind for maximum generation (like you see in commercial windmills) - no rocket science, just a single vertical “wing” attached to the opposite side of the turbine. Wind blows, gadget swivels to offer least resistance, making our generator face the wind head on. Done.
There are some others. Not sure if they should be mentioned here, or separate threads or if you people are interested… will see replies and decide how to proceed.
Happy to be here.
