Solar Robotics

at 5:25 am. Filed under DIY Hacks, Electronic Hacks

This is an neat little solar robot that would be cheap and easy to build.

“Make your own solar powered robot at home using things you probably already have. Transistors, resistor, capacitor, solar battery and flashing LED are available at any electronic store, if you don’t already have them. Solar cells out of calculators work as well, you might want to use more than one since they are really small. If you do, connect the positive wire from each solar battery together. A small motor should be used like the ones in walkmans. Solder everything together and watch it come alive. Put it under a light and let it charge, it should take couple seconds for each burst of energy. Works best in sunlight. There are two solar panels connected in parallel providing more power, and there are two 2200uF capacitors connected in parallel giving 4400uF.”

    What’s a solar battery?

  2. Alan Parekh Says:

    He means a solar cell (solar voltage source).

    Sounds like a great way to get that extra ‘burst’ of energy that I often times need in the middle of the afternoon.

    hey where can i get the full info to build this solar robot? cuz i tried to make something like this a few months ago and i failed i would like to know more about the transistors used how do you connect them and about the capacitors i need the full information cuz i know a lot of electronics but i have trouble with theory he he.

    Hi Rafael,

    The link is in the article, it links here:

    Give us some feedback if you end up building it. 🙂

    hey thanks a lot i’m buiding it right a way, hope it works.
    I have some small proyects of my own (turning on a white led with just 1.5v batery,) i have already done this but the thing is that the transistor i used gets a little hot after a wile and i dont know a lot about the difference between transistors. do you know were can i have some info about this?
