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 :p

Re: another first DIY spirograph w/ red, green, bl

If u are still wondering of a good way to cut glass, u can take a utility cutter( a box cutter blade inside of a sturdier casing) and score the glass. When the glass is weaker, it should break evenly along the line that was scored.

The mirrors arrived today. They only charged me the original $6 for 10 of the #L1313's, but each of the ten little envelopes contained a single
#L3129D - i.e. the $5US mirrors. I basically got a free $44US discount, and the mirrors appear to be better than the ones I ordered. I'm pretty happy with this purchase.
