Beam Symet

This beam Symet was built unlike most, this beam Symet is not solar powered. The circuit used is a modified version of "Led Flashing Circuit" by steven123654. The brains of the Symet is a 555 timer chip used to make the motor spin once per second.

You can use a 3 volt solar panel.

That's a great idea, when I built this I didn't have many parts to work with and no cash for any panels. But I've got some now so I just may make a solar version. Thanks!!!

go to your local dollar store. They usually have some sort of solar garden light, and those solar cells are 2.5-4volts each :)

does the capacitor have to be 470 Uf??

Nope, you can change it out to different values, that will change the amount of time the motor runs (which in turn the recharge time).

thats so cool and is that 555 chip an ic? btw i built the "old-fashioned" symet using a solar cell. nice job too, your robot is one of a kind :) !

thanks, and yes the 555 chip is acting as an IC. I really like your symet, the book you used, "junkbots,bugbots, and bots on wheels" was what first got me into this as well. I would love to see more of beam robots as you create them and if you need any help, i would be glad to try to help.
Happy Beam-bot-ing
