The device will use a ordinary digital alarm clock to trigger an electric motor momentarily. The average tinkerer can easily build a similar machine and I hope my Instructable guides you smoothly through the process.
Lets get to it!
Step 1: Lets Get The Parts We Need
(I have tried to include a part number to get most parts although some of these things can be found locally too)
1. A digital clock radio - the bigger and cheaper the better.
2. A car door lock actuator - (AllElectronics #DLA-1)
3. Machinists Magnetic Base - (LittleMachineShop.com #1237)
4. Prototype Circuit Board - (Digikey #V2012-ND)
5. NAND Logic Gate - (Digikey #CD40107BE)
6. MOSFET - (Digikey #IRFZ14PBF-ND)
7. Potentiometer 100k - (Digikey #490-2971-ND)
8. Capacitor 10uF - (Digikey # P5148-ND)
9. Resistor 1k (qty 2) - (Digikey #P1.00KCACT-ND)
10. Diode 1N4001 - (Digikey #1N4001FSCT-ND)
11. Battery 9v Alkaline
12. Miscellaneous - (zipties, wire, hardware, glue, elastic band, heatshrink, etc)
1. Various screwdrivers
2. Soldering Iron
4. Hand drill or drill press.
6. Hot glue gun
7.Heat gun or lighter
8. Hammer with center punch.
11. Permanent Marker
Step 2: Design The Circuitry
The solution is a simple circuit that will briefly turn out actuator on and then off, even though the input is always high.
