Hello Jo, Could you provide some details on your mechanics? Turning by means of the rear motor appears to be most successful if the weight is in front, least...
If you think about it, charging a cap with a solar cell takes longer in low light conditions. Low light = lower current. Think of the cap, as in Wilf's...
MY understanding for the reason for the 3 second delay was to level the playing field by preventing exotic ($$$) high efficiency solar cell to directy drive ...
Thank you very much, David. There's lots to dig into. I keep coming across the "FAB" book and really must find the time to read it. J Wolfgang Goerlich...
... Great, for I would love to build one! Studying turbots with similar circuits and different mechanics is sure to lead to some new insights. Appreciate the...
Hello Myc, A level playing field is a noble goal. Yet it would not have been applicable in this case. There were no exotic parts, simply good construction. I...
As a side note, it occurs to me that adding steering phototaxis would make Disk Drive a fierce competitor in the Photovore Exhibition. J Wolfgang Goerlich...
Problem repaired. Now the circuit says "CMOS 555 x1". Sorry if I made anyone waste some components... jeje Juan Cubillo CostaRican Beamer!!! ... From: "J...
I´m also doing a bot and it´s going to be just GREAT! Many features, small size... I just have to hurry if I want to finish it on time. BTW Can I show my bot...
I took a look at the photos. Very nice design. Definately covered all the bases: geared motor, extra light capture, large wheels. Again, great design. Couldn't...

I just checked the website earlier today and it seem the deadline has been extended to Dec. 7th. http://solarlife.solarbotics.net/index_files/Page839.htm ...
I came across this new toy from Japan "Walkie Bits" They are these tiny walking Turtle robots from Japan. Here you can see a video of one in action. ...
Hello sir, This is to address Mr. Wilf Rigter and Mr J Wolfgang Goerlich, I think both of them are the most active in the group and probably one of the Best...
If they can turn, then they would probably be be a good source of gear motors, maybe even a small hackable platform, but otherwise, they are probably just bare...
The person that bought them says in his web page: "As soon as I figure out the Japanese manual, I should be able to teach it to chirp and move in predefined...
I have some Walkie Bits, and would be happy to put one on the operating table and dissect it, if people are interested. They are cute, and extremely popular...
I found some more information in a Takratoys PDF http://www.takaratoys.co.jp/ir/eng/company/press-release/PDF/050630.pdf They are 5cm in length and have a...
Thanks a lot Jo, Wolfgang and Bret for your replies. after I posted the questions I proceeded to strip yet another motor. I'm beginning to regret trying to...
Thats cool you got one :)im envious. I think im going to pick one up on Ebay even if they arent really hackable or a good source for parts. Perhaps down the...
... Looking at the pictures it would seem that the solar cell was higher than the 6 inch limit. It could just be the view of the pictures. Gord ... ...
Hey Eric, driving these motors form the AC240 chip limits the amount of torque and should (in theory) prevent the motor gearbox from stripping. Driving from a...
Hi J, Amy time records are shattered in competition, there will be a discussion of the 'legality' of the winner. This is no reflection on the organizers of the...

Hi Wilf, No I haven't found any 5m pots, I do have a few different ones ranging from 1k up to 500k but I think they're all different sizes. I stripped the...
A solar cell is a current source with a capped output voltage The voltage rise of a cap being charged by a solar cell is linear (straight line) up to about 80%...
