Re: another first DIY spirograph w/ red, green, bl
Eep, then I wonder what they put in the box that should arrive here Monday?
I'll report back here when I get the package.[/quote]
yeah, i bought a lot of those and they said they don't offer it anymore... they gave me a discount on the $5 mirrors though b/c i wanted so many, i bought like 18 for $3.90 each about.
not bad.
i hope to make a few 3 mirror spiros in project boxes and sell them. should be an interesting venture
i'm also going to use mine for parties and try and find a automatic pot to switch randomly between different values to change the design, that would be awesome. anyone know how to do that?

You can figure out the resistances you need for each motor for the design you want, then create a resistor path with that resistance. Then figure out the resistance for a different pattern you like, set up another resistor path etc etc etc. Finally, put all those paths on a multi-position switch such that when you switch it to a given position, it completes the circuit on the resistance path you want for a given design. Or if you want to get fancy you could do it with a programmable IC
