So far I have been able to acquire for free an 80mm case fan, the hard drive magnets needed, a cigar box, and a 12v 500mA AC to DC adapter and a stir bar.
The one thing I am needing is something to regulate the voltage. I have been looking at pots as an option, but most of those I am looking at are 2W at the highest. Based on calculations the AC/DC adapter will be pushing out 6W of power, thus making the pots wattage limit exceeded. What other suggestions to you guys have in regards to this or where can I find one that will meet my needs?
