honestly, I'm not too familiar with the mechanism with which reverse-biased infrared emitters/phototransistors work, particularly in reference to photopoppers....
The reverse-biased components are generally photodiodes. You can usually replace them with LDR's, however, this can depend on the circuit you're modifying. Do...
I'm happy to be corrected on this, but I don't think a direct replacement can be made. The original circuit relies, I think, on the photovoltaic output of the...
Here's another one you might want to look at, Jake. http://tech.groups.yahoo.com/group/beam/files/Jo%20C/393bug.gif It's Wilf's ultra simple 339bug. I've just...
Hi. BEAM fodder. I was doing some searching for a good deal on the 'AirHogs Havoc helicopter' and found a place that sells the motors, batteries, and defective...
Hi. I've been working on this off and on and I'm almost finished. What do I do whith the spare Enable pins on the L293D (pin 1 and pin 9)? Do I just connect...
do you have pics up of this creation? mike ... From: jabmechtech To: beam@yahoogroups.com Sent: Friday, October 05, 2007 9:34 PM Subject: [beam] DozerHexapod ...
The L293 dual bridge requires logic high enable signals, so to enable a L293 bridge, tie pin 1 and/or 9 to Vcc. To add a simple delay at start up, connect a...
Yes, but only of what I've done so far. It is not finnsed yet. I'll get a video of it and more pics when it is all done. jab ... pin ... to lack ... and ... an...

Hey, realy nice, clean and well made looking bots you've got there Jesse. It would be cool to see them in acttion. How small is the 5 motor walker? jab...
where are these pics? =) ... From: jabmechtech To: beam@yahoogroups.com Sent: Sunday, October 07, 2007 8:09 PM Subject: [beam] Nice pics Jesse Hey, realy nice,...
thanks guys! I just got around to taking pics of a few of my bots. the 5 motor walker is 7 inches long, 3 inches wide. i'm still experimenting with the nu...
Harold has a great site with a lot of pics and detailed descriptions of his work. he has built some 5 motor walkers. here is a link to his last 5 motor walker(...
I saw this and was pondering what BEAM applications this might have. http://www.youtube.com/watch?v=-GgOn66knqA&mode=related&search= Has anyone tried to build...
We had a good discussion about Theo Jansen a while back. Search the archive and you'll get quite a few hits. As for Beamish versions, James Watt from...
OK, I chased this down to a bad pager motor. One of the windings has an open and when the motor stops on this section, the solar engine cannot charge. Once I...
Hi. well, (scratching head) It is almost done. I have to wait for the batteries to charge befor I'll know what happens. I touched 6vdc to the main (+) and (-)...

Hello all! I just finished adding more images and some video clips of my walker, Hermit. This is also dedicated to all who wants to build one (as a reference)....
HI. IT LIVES! (evil laugh) I put the fully charged batteries in this morning and 3 1/2 hours, and much reworking of the wires, later it lives or at least it...
Very cool! I like the side step around the stick. Is turning gate and step hieght all done with the 18 dip socket and the resistor comboes? jab ... walker,...
Thanks, Jab! Well, I was just bored that's why I made another videos and pics of Hermit. The turning gates and the steps are all done by balancing the weight...
Wow! That's excellent, Jab! Really nice work, I like it! I think you should make a page for it. Thanks for sharing that cool bot of yours. I enjoyed watching...
Thanks Harold. Yah a page would be cool. there is a lot of info about the build and how important it is to get the whieght balanced at the mid point. and the...
I'm still pluggin away at prometheus with several redesigns to get the behaviour controller working just right. As some of you may remember that bot was hacked...
