looking to build my first solar powerd beam bot - Electronic Circuits Projects Diagrams Free

davidbball13 · 10th May 2008, 01:38 PM

can i use calculator solar cells for a beam bot this would be my first bot and cells have about 1.9 volts in full sun light and for the ma i dont know i have a very shitty AMM it was like 5 bucks from the shack.

also do you guy have any advise about building one.

Solar cells generally are only low power, and calculator ones are absolutely miniscule - although in bright sunlight they may be enough to give it an occasional 'kick'.

so they will work

Try it and see, personally I suspect they are too low a power to be workable.

ok i need better solar cells/pannels for future bots i will make this bot later today. but were is a good/cheap sourse of solar cells i have seen the solar garden lamps they are like 4.75 on allelectronics.com

I think there is a whole seller of broken ones that would be cheap ?

This is just one of them.

Except for the shipping I think 9+ us dollars it's cheap. Start scraping out the seat cushen's in the couch then order them and do some testing. If anything but a cheap lesson. Keep some around for other project's ?

Each one will measure a different voltage of course. The first time I saw this I was tempted.

$2.50... There are two cells, about 2 inches square. Each gives about 3 volts no load, and about 20 ma. About as cheap as you can find, unless your neighbor has some in the yard...

http://www.solarbotics.net/

The most complete B.E.A.M. site I know of, and has many circuits and build plans. Plenty of of information about what you can do. Most of the solar powered ones use a small solar cell, like from your calculator to charge a capacitor, then dump it quickly to a motor, for a short burst of movement. Plenty of videos of these there as well.

Don't steal them idiot! Just buy them. Better yet find some broken yard lights.

killivolt · 11th May 2008, 02:48 AM

Tell the guy if he didn't give you 9 bucks 5 of his yard lights might come up missing. Better yet take five and tell him if he gives you nine bucks you'll now where to find'em.

But if you want to be a true experimental Project builder you'll go over and ask him to donate to your project throw in a free lawn cutting ? When it's done you can show him how it works.

Start the lawn mower and go get it. Market yourself.
