Stir Plate

Feeling motivated after reading about DIY stir plates on a few brew forums, I decided to give it a go. This is a list of parts that I used:
  • Rheostat - 3 watt, 25-Ohm (RadioShack part #271-265, $3.99)
  • Flip Switch - most will work (RadioShack part #275-711, $2.99)
  • Control Knob - most will work (RadioShack part #274-407, $1.99)
  • Project Enclosure - 8x6x3" (RadioShack part #270-1809, $6.99)
  • 120mm Case Fan - a smaller fan might fit better (RadioShack part #28-1108, $9.99)
  • 2 - 1/2"x1/8" Rare Earth Magnets - a 15 pack on Amazon ($8.99)
  • Large Washer - from HD ($.29)
  • #6 2" Machine Screws & Washers & Spacers - from ACE Hardware (about $2)
  • Cell Phone Charger - from a retired Samsung cell phone
  • Stir Bar - octagonal bar with pivot ring from Ebay ($4)
