Hi group! I'm just wondering, maybe we could use a photoflash/er from a disposable camera, to make a photovore or some sort. My idea is to attach a solar cell...

Well, think of it.... the photoflasher I'm experimenting with, uses a 1F cap. When you apply power to it and switch it ON, a small light bulb lights up which...

Remember that the flash unit charges the 100uF high voltage capacitor up to 300V. Since the energy is 0.5C x V xV, that is a lot of stored energy which can...
Hi Wilf, thanks for the reply! Yeah, you're absolutely right. Well, my cap (in the photoflasher) indicates that it's a "1F" cap but no voltage labeled. I'll...
Hello again Wilf! Oops, I was wrong. The cap in my photoflasher says 160uF 330V. I didn't notice, hehehe! My bad. :) Well, it's my free time today, I should do...
... supplies several amps of current. So you need to have some heavy duty storage eg a 1F / 5V cap for one or two flashes or a rechargable battery to run at...
... as i understood it this was just how photopoppers work - you pour charge into a large capacitor and once it hits a certain voltage (significantly higher...
... A "typical" photoflash takes about 5 to 10s to charge up the 100uF cap to 300V or so from 3V. One reason some flash units seem to charge the cap quickly...
I have been interested in building a Headbot with a dual power source consisting of both solar and battery power, with the solar cell recharging the batteries...
I think Wayne Christensen did something similar recently. There is a circuit here: http://downloads.solarbotics.com/PDF/kit7.pdf that flashes an LED when the...
... Why not try your hand at a Turbot? The mechanics are much more forgiving that walker. The motors and battery packs can be reused in robots as you progress....
Hey everyone, I'm drawing up my plans for the next hexapod and was hoping for some input in regards to turning. Assuming I use the same circuit as I have for...
Hi Wolfgang! The legs movement during a turn would be as follows: 1. Form basic tripod by lifting two legs on one side and one on the other. 2. Move the two...
Hello all, If I hook up a motor to a 5v regulated supply that can supply a maximum of 1A and then deliberately stall the motor what will happen if the stalled...
Hi Tom! In regards to hexapod project, here's a friend of mine, Ralph Cañas, who've made this nice hexapod. Pls. check it out, he also got schematics and a...
Good question Chris! The photoflash works similarly to an car ignition system which uses a ignition coil (transformer) with a 12V primary winding and a high...
Well, I made sure all of my solder connections were good. Resoldered as needed and I have a working BEAM bot. Yeah! So for the begginners out there like me...
I'm a beginner too and I just finished a Solar Bug 1 Combo kit from PagerMotors.com. It has a circuit board which I thought would be easier than a free form...
Thanks Harold, thats a very interesting hexapod. It appears that the front are rear legs are connected, allowing the robot to only use 3 motors!! ... ...
I have thought more about my initial concept for turning and realised that its oncorrect and would only result in a robot which turned a bit in one direction,...
Hello group! Well, as of now, Ithe photoflasher-photovore idea is still in the experiment on my workbench. But right now, I'm breadboarding my upcoming bot...
I have less time to spend on bots than I'd like so I thought perhaps to keep it going by converting one of my toy tanks that I never play with. I was wondering...
Hi Tom! Thanks! But this is not a walker, it's just a photovore. The main goals (process) are just to seek out light...stop/pause near it...then recharge. When...
Hello Henrik! Well, if I were you, I'll take off all the parts in your toy tank except the motor/gears and its tread. I mean, only the electronics will be...
Oh and by the way, the Li-Po batt I'm using is 3.6v 800mA, slim type. I think I'll stick with these kind of batteries for my bots. It's light and strong (more...
