Inspired by this thread and out of frustration about stirrplates on ebay selling for € 50 - 100 and even more, i decided to build my own
- 12 V plastic PC-fan
- 4 screws M5 x 40
- on/off switch
- led
- 650 Ohm resistor
- 1 kOhm potentiometer
- 12 V - 500 mA powersupply
- PS box approx 150 x 150 x 60 mm
- 2 neodymium powermagnets 8 x 5 mm
Overall cost ~ € 25.- and I could have saved half of it by ordering things online instead of buying at the local electro place.
This only took two evenings… I need a new project already
