Can ou help on overal cost of this project?
A really great project that I would like to build but I am stuck for a parts list for Actobotics. Does anyone have one? Also the author talks of a second version which would have a real time clock and that would help. Any news on that?
What a brilliant idea. The kids where I am are spinning away and this project is one way to utilise the spin. I regret I find the spinners that are popular rather dull. All they do is just spin. So thanks for renovating an old idea and turning it into something much more interesting. Are you or anyone here able and willing to contribute more film strips?
What was the power source? I know it was batteries but how many, what type and what voltage?
"Failure to operate a device like this in a poorly ventilated area could bring permanent personal injury or death."You may want to re-word that. Your device must only be operated out of doors where there is very good ventilation. Operating it in closed spaces will cause the serious problems you mention.
