... I should have mentioned that my first 'cat' was connected by nothing more than double-sided foam tape (DSFT), with just that in mind. However, that was not...
I just built my first 2 motor walker before the year was up. I wanna build a three motor walker kinda like Chiu's. I have never built a microcore before so...
Hello all, hope you had a good xmas and new year. Since i started beaming, i'v always liked pummers. The gentle fade in/ fade out of an led. Trouble is, every...
is there a Circuit that will work with 3 different motors. my idea is to use one for direction, one for forward and reverse, and one to turn a bot body to...
Shawn asked: Thursday, January 03, 2008 3:58 PM ... Perhaps you mean something like this? http://www.semiconductor-sanyo.com/ds_e/ENN6195A.pdf So it could give...
That does look good but im trying to run a gear box and needs more high voltage for it to turn or run. i have it hooked up to a 5 volt source and it works...
ok i have a panel (4.2 volts) a cell phone battery 3.6 v now i just need a circuit to charge the battery so i can charge or power devices via usb connection,...
hi. just a thought. you could use a Dozer with motor driver (L293) and reverse,to drive the bot and look for light. this would solve the motor gear box...

Hi Randy, Sanyo hasa number of very nice low votage / low dropout motor drivers. The LB1630 is basically BEAM on a chip, check the files section forsome ...
You best friend in this world when looking for an answer is google.com Have you ask google your question? "charging lithium battery usb" what are the first two...
... have done this before, it works well. I have done the same thing with my escap. I suggest buying them and sell the rest on ebay. They will go quick! Good...
The gear box is for the bot turning the whole body in either direction not for forward or reverse i have a chasis for that and the motors are already installed...
hi. here it is, finnished for now. the legs might need some more tweeking, but it looks GOOD. :) http://www.youtube.com/watch?v=sSR8ctQtGNQ thanks for all the...
Hey all, I have a surplus of small microphone elements (the two-wire type you find in phones, etc.) - and I am looking for a circuit that will amplify the...
I just saw a video of a very cool small dolphin robot... http://www.youtube.com/watch?v=YaXnBrSt6kw It uses a magnetic field to make it move...any idea how to...
An appeal to the gurus of BEAM... How could one implement the following behavior on a BEAM headbot: If the head has been at rest for some period of time (say,...
The LM386's datasheet has basic amplifier circuits. I'm not sure what microphone elements you have, but assuming they are condenser elements you just need a...
Something simple that turns the head 180 degrees from its resting position, then switches it back to light seeking mode? This would allow the head to find...
... Neat! The mechanism is similar to magbot designs. Check out Solarbotics' SunDancer kit for one example. You can occasionally find these in one piece in...
Hello Groups, Can anyone tell me if there is a MAXIM chip that could be used as a motor driver(like a L293D) and can power a standard dc motor? Thanks in...

Hey everyone, hope all had a good holdays. I wanted to build a 1 motor tumbler in the confines of a 24X33 mm solarcell, and the first attempt was quick and...
