-Waiting for a sunny day to try this out. I cut a few corners with this solar racer. Let's see if toothbrush heads can really substitute in for wheels: ...
The first link below takes you to a long list of prophecies that were issued in the mid-1990's, that have all come to pass exactly as predicted. It also...
... I think that you are an idiot. Malthus predicted mass starvation would occur in "his near future" because population growth appeared to be exponential and...
Are these components comparable? I found a circuit I want to replicate. Just wondering if I could substitute the 3904/3906 transistors. I will admit...The data...
... They're both amp/switch transistors that work at least in the Audio range, although the 3904 goes to "100Mhz". The 9013 carrys a LOT more current, but I...
Thanks! I'll breadboard the circuit in the morning and see what happens. Voltage shouldn't make a difference since the circuit is made to use no more than 1.5v...
I get the urge to build a BEAM-something...I have read forest mims, and can read a schematic but really suck at translating that into physical circuits but I...
Thanks for the inspiration from solarbotics.com, specifically http://smallbotics.solarbotics.net/symets.html Not only are there interesting photos of symets...
-Potable or portable radios? Possibly a typo there. Glad to know there are more transistors available than 3904 and 3906. I'm familiar with the 2222 and 2907...
-"It was predicted in advance": what grammar is this? Who predicted "it?" I consider this sort of writing Journalese. Some would call the sentence structure...
Here's one that I made, but it's not a pummer.  http://frankendaddy.deviantart.com/art/RoBonzai-66392238  It fires a motor in the base that jingles some...
like the bell idea... what would be the effect of doing the reverse, wired in series on each limb...then in parallel between limbs? I'm not sure what the...

Not 2 hours after looking at your tree I "StumbledUpon" this... http://www.igreenspot.com/recharge-your-appliances-through-a-solar-powered-plant/ ... I used...
Ya, I've seen that, but it was just a design, not an actual device.  I think that there's an old solarbotics.net page detailing how to make them. I did it...
I finished it up yesterday. Check it out here: http://akapplegarth.us/index.php?page=modified-edgebot The tail skid is a 10mm blue LED that is actually the...
now THAT is the way to describe your bot. Great detail and clear instructions. Good Job! Keith Applegarth <keith.applegarth@...> wrote: I finished it...
It was just weird that that came up only after I read about yours. I actually like the base of yours better, the techno tree from a old piece of techno junk....
-I trimmed the paper clip legs a bit. What a difference it made! The little bugbot, which I call Spidey, now moves about, as if in search of food, or perhaps...
Hi, I don't know if it is appropriate for a noob to post a question here? Please tell me if it is unappropriate. I am taking my first steps in electronics, and...
-I've noticed some motors are great for symets but others aren't so wonderful. Small motors from CD players seem compatible with at least some solar cells....
Thanks for the information! So do you think that the fact that I have no voltage difference across the engine, is because the engine is not good enough? I ...
I just realized that I did not mention the behavior of the circuit. I have updated my website with the information on my main page ( http://akapplegarth.us/...
Maybe someone else can help you in that regard. I just started building BEAM bots a couple of months ago, myself. Sort of shifted over from circuit bending,...
Btw: my experiences with robot building (as well as circuit bending) are based partially on trial and error experimentation. So if you pop in another motor and...
