... Both depressing and rather heartening. A Robosapien AND another toy is only worth $2.00 - only. But then, given what jabmechtech sez, it is definitely time...
I recently picked up a roomba for $5 at the goodwill as-is store and my good friend Dan Gates picked up a friendly robotics lawn mower at a yard sale for $25 ...
Finally got the circuit working correctly. I'm extremely happy with the results. It flies, but for some reason, optimum operation is in part shade, it...
I had gotten it into my head that it would be fun to make a colony of pummers - but I haven't progressed much further than that. I've got a few notions, but...
I think this is a great idea,and one I'm sort of working on too.I've got quite a few record player "arms"which are great for making pummers. A bunch of those...
I definitely agree that it should be solar, I had imagined a giant communal battery that was contributed to by all of the individual pummers' personal solar...
If each Pummer has it's own BEAM core controlling it you could do all sorts of things by allowing individual Pummers to communicate with each other. The first...
I made a solar powered led flasher from a 74HC04 but instead of a normal resistor I used a ldr. I was out in the full sun and the led was going so fast it...
I believe there is a project from EMSL that is similar to what you are talking about.. They don't make a colony, and the communication is via wires instead of...
I love this idea of interactivity. I have hundreds of salvaged LEDs of all colours and shapes I could use. The possibility of harvesting all available light by...
... The short answer is a definite yes - normal LEDs will act as a photodiode when reversed biased, with their peak sensitivity being the same frequency/colour...
The popular 'Joule Thief' circuit is fantastic thanks to it's simple design, robustness and tiny size. If efficiency is a higher priority however, BEAMers...
Telefox I agree with your post but further to it, the joule thief (or its like) are designed to pull the remaining power from non recyclable cells such as...
Just thinking out loud, but, instead of using a microcontoller, would this switching using the LED be feasable using many fewer 'controlling' circuits but...
Hi. What was your first BEAM or BEAM style Robot? there will be an intergroup meeting in Second Life on how to freeform a FLED and make a Symit. next week...
... Solar engine on a scaffold (think: thing they hang people from) that had a set of chimes attached to it. The trick was to get the chimes to hit each other...
1. 1972!! Photo-Head using OC44 transistors as sensors, AF114 transistor motor driver( from my Dads NEW Transistor radio!!! ) 2. 1974. 2 x OC71 transistors...
2000 1) separate light activated transistor switches hooked up to motors. solar powered. Actually phototropic. 2)Photopopper style photovore 3)2 Motor...
I don't think there would be any problem with increasing the mode switching speed, provided both the 'sense' and 'light' phases were long enough for the LED to...
Hey all. A while back, I believe there was a post concerning the control of Nv timing in a microcore with one potentiometer. I think the rationale was used in...
Just over a year ago I stumbled across the whole BEAM/ANN concept, and the first circuits I made were all things that flashed and chirped using 1/2/4/6Nv...
Thanks for the information, the link doesn't work though. I think I get have an understanding of what you have written. The key was the diodes, I didn't think...
