Default Re: spirograph project help

For the pager vibrator motors, I've found that 100 ohms per volt of battery supply works well. It's just enough to bring the motor to a halt. (So for 1.5V I use 150 ohms, for 3v 300 ohms. Use less and the motor won't stop, more and the adjustment is only at 1 end of the pot.)

hope this helps,
kernelpanic

potentiometer wise i actually found a DIY on indestructible.com that had 1 very true statement, you can use the volume control from any electronic with a volume control as a potentiometer

I used a volume control on my first spiro, as they are usually logarithmic any speed change is over a very small part of the pot, as they soon get into the megohm range, making it hard to set slow patterns.
Most other pots are linear which makes them easier to set.
