Hi Mark; ... I have never liked this part. OK, it has it's uses. I have used it. My basic problem with the L298 and others like it is the poor efficiency. It...
Hey all. I'm confused. I know that if I hook 2 1F 2.5v caps in Parralle I get .5F at 5V. But if I hook 2 1F caps in series do I get 2F at 1.15V or 2F at...
... Nope. If you connect two 1F, 2.5V caps in parallel you will have a 2F, 2.5V cap. ... In series you would get 0.5F at 5V ... OK, you need 1F at 5V, so this...
... Dough that's what I ment to say. (I knew that) :) ... Thanks that's what I thought but wasn't sure. ... Making a cybug solar powered. ... Thanks Ori. ...
I just got my hands on several electrolyte caps. I'm looking into a charge pump circuit design (my own). But I need to hook the caps in "parallel" to charge,...
Making a Cybug QueenAnt solar powered is easily done, since it sips very little current, but making the Cybug Scarab solar powered would be tougher. It's a...
There are a buncjh more interesting "thyristors in dc motor driver circuits" in this application note http://us.st.com/stonline/books/pdf/docs/5201.pdf wilf ...
... This discussion resembles one that took place recently on the Open Source Motor Controller (osmc) group recently. The following is a copy of a post I made...
I just made a post regarding using relays as the high side switching element for an H-bridge. I got to thinking (always a dangerous thing!) and realized that...
Decreasing the resistors didn't seem to help. It think it needs a bigger deadband zone between the motor rotating left and right. How do you make the zone...
... Not necessarily, Dwayne. I had to use electronic braking on Hider (a relatively fast wheeled robot). It turned by stopping or slowing one wheel; without...
Hi all, I don't know about you guys, but I am used to charging up a battery by figuring out what resistor I need to provide the right current, set my power ...
cool! ive been looking for something like that to make a robot that could sense when the battery was low, and head for a charging station and charge up or...
From Wired News yesterday: "A self-proclaimed "digital god" and the author of Creation: Life and How to Make It, Grand has been called Britain's most...
Hiya all, after lurking for ages I've finally had some time off for beaming again. I've taken on the ShokPopper2 and have a few questions regarding that. My...
... I've done a quick search on Google with little luck. Still I only turned up 3 hits! I think it could be refined by basic knowledge of search terms. I...
Bruce's Hider was an inspiration to all BEAMers, and I think that everyone considered building at least one similar robot, that has a handful of layered...
Hi, I am new here. I have not touched a breadboard for 8 years, but recently have become interested in BEAM. I have read about the bicore, both grounded and...
I just got one of those Zip Zap micro rc cars from radio shack. Its a great car, but far from perfect. It will become perfect, one mod at a time :-) Its got...
Forgive me if this is duplicate, it didn't come up yesterday...And this has revised diagrams... Anybody looking for a mini-sumo circuit? I am almost finished...
There have been some BIG delays - That "Behavior Prioritization" one that was just recently received in my inbox (I guess everyone else also got it at 8:10?)...
I tried to solder some wires to a Panasonic 2422 cell but after the flux cooled, the whole bump peeled off and I couldn't get it to stick to the cell after...
Oooh, that happened to me with the very first solar panel I got - the pad ripped off. It was so disappointing! There are some ways to make a connection, but it...
I (and probally others) would like to see this pick up a lot of steam ... From: Paul L. Robertson To: Wade Cornell ; Teresa Jafry ; Susan Lewis ; Shawn Hamil ;...
Hello Dwayne, Sounds interesting. Do you have some links to the various motor controllers that have evolved during discussions on the Open Source Motor...
You can try making a small C shaped clip (out of springy metal) that will fit tightly around the cell pressing on the area where the pad was. A bit of tinfoil...
