Default Less than $50 for AutoDosing? Oh YEA!

I see some DIY peristaltic pump threads and think
DEER GEEZUS! you all spend alotta money

go the cheap route..I did

Pump Head w/ motor ($20)
Ebay: 281010726171

12v 1a power supply ($5)
Ebay: 261110138053

Enclosure ($6)
Radioshack: 2062281

Digital Timer ($10)
Walmart: 16816087

Total: $41

some tubing, some solder and some basic tools (a drill and screwdriver essentially) and VOILA! cheap autodosing

I actually went a little further and connected a speed control to fine tune the pump flow BUT I realize that at full speed, I get about 20mL (and could easily adjust my concentrations to dose everyday for about 2.5 months before refilling)
