I had to repair one of my wife's solar garden light ornaments, which is shaped like a snail. An LED glows through a transparent, coloured plastic shell. ...
Solar-powering the tutorial Turbot is possible with a few modifications. First, use a high-power solar cell or substitute the motors for something more...
Hey, thanks a lot JWG! Well, I just hope I can still do more interesting BEAM bots. Oops, by the way, Rovore is nearly fully- charged by means of my 100 watts...
Nice example of a solar engine with relatively high leakage current, in this case, ~400ua. There are other hyper simple circuits with similar performance. ...
Guys guys guys! Hi again to all! Hey, I just finished uploading 2 new video clips of Rovore, under the video clips section. Enjoy and happy BEAMing! See yah! ...
Well done Harold! I am in awe with the depth of detail and marvelous presentation of the project. Some of your best work yet! I will have some more technical...
Hi Wilf, Sir! Nice to see you again here! :D Oh, thank you so much for the warm compliments. Thank you! ;) Well, I know there are some technical issues about...

... Hello Jabmechtech! You're welcome! Well, I'm not yet in turbots, bu I guess you can use solar engines to make a small turbot. The idea here is to use a ...
Oh and by the way, you may want to experiment with "voltage pump" circuits for your turbot. You can use the voltage pump or the voltage doubler to kick more...

Hi all, I recently spent an enjoyable afternoon helping my 8yo son build a kit robot at a school holiday program run by the Australian Commonwealth Scientific...
What about this circuit using a small bridge rectifier? http://www.user.dccnet.com/wrigter/motordecoder.gif wilf ... kit ... produces ... care ... the ... have...
Or this 2 diode motor decoder that has 4 distinct motor states: http://www.user.dccnet.com/wrigter/motordecoder2.gif You can even drive motors directly with...
Has anyone seen the paper "Systematic Deployment of Stratified Roboecologies" by Mark Tilden? I am looking for a link or a reference. Any help appreciated. J...
Thanks, Wilf. Your circuits have given me food for thought. (I especially like the 2 diode decoder). Unfortunately, they don't give the required 'stop, rotate,...
Hi Jo, Sorry bout that! I should have read your post first but I just had time to glance at your circuit and replied without understanding the actual...
Robots That Feel Like Rats By Greg Miller http://sciencenow.sciencemag.org/cgi/content/full/2006/1004/4 With their dismal vision, rats rely on their whiskers...
Jo, I understand it better now. The bridge rectifier version I posted should do the job but you need a Gray code counter and the Beamsonic circuit to drive it...
Nice work, Wilf. I don't have a 74XX74 in the spare parts draw at the moment, but I will pick one up for a play when I next pass a Jaycar store. (Like...

G'day Bill, I'd be glad to try an explanation. These things always work better with hastily scribbled sketches and lots of hand gestures, though! Can't supply...
Thanks Jo for your excellent explanation. It abuses the principles of good gear design the way BEAM abuses digital IC's. I have spent the day building...
Oh, that is so clever! It's marvellous what a good mechanical design can do. Having been a bit neglectful of the 'M' in BEAM in the past (concentrating on the ...
Hi Wolfgang, Nice link. It had me wondering how I could implement whiskers. I don't have any strain guages to measure the torque on some whiskers, but I was...
