  • LiPo/LIon Batteries From Laptop Cells

    Balance Charger: I bought a pair of these...will be easy to use and cheap.http://www.ebay.com/itm/12V-BMS-Charging-Charger-Protection-Board-Circuit-3-Pack-18650-Lithium-Battery/132088051421?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

  • Electromagnetic Fidget Spinner Accelerator

    Hmmm how about the power of light? I have some 2 watt lasers that pack a punch ( goggle mandatory ) but perhaps photons can spin something for fun? I may try this.

    How to Make Faux Rocks

    Another method is to dig a hole in the ground the shape you want (upside down of course) then make a sticky mix of your concrete and line the hole. When dry just lift the hollow rock out and turn over. You can line the hole with plastic drop cloth and sprinkle in some colorant before adding the concrete and finish off later with other coloring methods if you like. The drop cloth provides nice handles with which to extract your masterpiece. No form to make!

    A friend of mine and I cooked this up several years ago. No pics sorry we did that at his place but I moved about 7 hours away since then. You can dig the hole any shape, depending of course on the consistency of the ground. Soft sand you might need to add water so it holds shape. The plastic will help and also add texture if you don't smooth it out.You would just have to try in your conditions. I reserected this idea because I am getting ready (for two years) to build some kind of garden with pond and here in Florida rocks are as common as hen's teeth.Good luck.

    Build a Plastic Vacuum Former

    Why not a small fan (metal blade protruding inside ) to circulate hot air? Mount motor outside the cement board with only steel shaft poking through and put a metal blade to stir the air. Slow speed, just enough to make for even temperature. Thinking small DC motor so you can easily control RPM

    Cool idea. I have wondered what to do with the 1500 watt heater elements saved from a defunct space heater. There are three, nicly shaped like very thin bricks!I already have a pump, originally from an O2 generator. Twin cylinder. Also have an air tank gathering dust.Since electrical and electronics are my thing I think what I would do is wire so the pump and heater would not run at same time to avoid tripping a breaker. Once you have saved a vacuum in the tank than your heat switch turns the pump off and the heat on.Limit switches on the arm wired so when you pull down to form, it automatically disconnects heaters and reconnects the pump.Another limit switch at bottom travel to operate a solenoid valve to allow vacuum to pull down plastic when it reaches the platen. (alternativly a bu...

(alternativly a button on the handle)I may make a slightly smaller version due to space and the fact that I mostly would make smaller items.

    I have a new electronic temperature controller laying around. I think one of those would do the trick. You can buy them on Amazon for $17 giving you dial in temperature with digital read out. Be sure to get the 120 V verson as they are also avalable in other voltages.

  • World First! DIY Real 4k (UHD) Beam Projector

    Wondering: A couple of years ago I made a laser projector (ILD) using an RGB laser module. In un-modulated mode when turned on it delivers a REALLY powerful white light beam. Could this be expanded to provide a light souce for this project. They are really not all that expensive for the 250mw version.
