What's the benefit of adding photodiodess to a photopopper? If one uses two separate solar cells and Miller SEs, isn't it already inherently photosensitive?...
Hi Eric, I was astounded with the performance difference between the Lil' Miller and the Fred photopoppers. Very impressive. Great video's. Just want to...
Wow! thanks for the great compliment. Lil' Miller is one of the few designs I can take credit for... partially. I guess "Frankendaddy" would be the grandfather...
Great design! Glad to know the originator. CostaRicaBeam is one of my top two websites on my favorties list (Solarbotics.net is the other). Both are incredible...
hi Mycroft I love the performance! the lil miller popper has a 3V .5F polyacene battery for storage, and the blue bug has a 2200uF cap. It wouldn't be a bad...
I'm finishing up a series of SE's and circuits on pcb's, all terminating in a 4 pin plug (+, -, motor in, motor out). They will plug into my photoppper test ...
I did a one-motor walker called FaxWalker (because most of the parts came from an old fax machine) that will reverse and turn. There are details, not quite a...
Well, I'm reading this on Sunday morning....More than 24 hours notice would be a help! Keep BEAMing and dreaming and giving us a week in advance :) Tom ... ...
You have the August issue already? I won't see it in my mailbox for another two weeks! But thanks for your interest in building Grant's BBPV from our...
No need to remind you to keep us posted, but I would be really interested to see how it stacks up. Which photopopper circuits are you planing to test? Juan has...
Hey Eric where is the scematic of the lil miller popper. I found the miller popper but it uses two 1381's so I asume your using a totaly diffrent circit. Gord...
hi Gord It first caught my attention durring a discussion a couple months ago and there was a schematic in the files section. this link is to the schematic I...
... Hmm. I had a project book back in the 70s that included a 'radio powered radio." Essentially it had an 'extra' "crystal" tuner whose output was rectified...
Thanks for the link Eric I'm going to try it using photo diodes so I shouldn't need the second mod. (BTW http://groups.yahoo.com/group/beam/files/PQSE1_2.gif...
A large antenna and normally a "true" ground. Would only work for stationary bots tike a head. I'm not sot sure I want a bot I would have to take down every...
Hi guys, I remember when that was posted and I had an idea for a neat use for it. Use it as a free roving bot recharging station. maybe for the charging ...
Hi I keep on ripping up hard drives only to end up with the spindle motor and the platters left over. Has anyone built a robot out of these parts? Does...
Thanks Tom, Looks good, but.... don't laugh at me, but how does it actually work? I know how the circuit works but I can't work out how the reversing and...
Hi folks I've always been interested in magnetism and the awesome, seemingly impossible things it can accomplish. Recently I saw a generic magnetic levitation...
It's not just the Herbie circuit that's simple and inspirational at the same time, but also the "Junkbots" Herbie body/frame. I've been quietly collecting...
As far as getting cheap NIB's (and cool levitation etc. experiments) check out forcefield.com. The idea of a wall of mags, with a hover-er on top will not work...
The magnet are great for Mag bots like the junk bots pendulem or a home built magbot butterfly. The bearings are usefull for making castors. Gord ... ...
Hola. Attempting to go to the FRED page on Gorobotics.net to print out for my little sister, and I get a "Cannot find server". Also was going to check my mail,...

I have already been working on this for a bit. I am 'producing' a consistant 1.5v. It consists of a 75' antenna (strung along 2 garage walls); a full-wave...
