This project describes how to build a simple, safe, and reliable electronic detonator. All the parts should total under 25$, and all but one of the parts can be bought at radio shack. This detonator includes numerous safety features such as a detachable power supply, an ARM switch, and an indicator light.
Step 1: Parts list
1. Project box (As close to 3x2x1.5 as you can get, remember you need enough room to hold the components but you want a good fit for your hand)
2. A momentary push switch (Model: 275-609)
3. Toggle Switch with On/Off Label Plate (Model:275-602)
4. 5mm Green LED (Model: 276-022)
5. 1/8" Mono Panel-Mount Audio Jack (Model: 274-251) its a 3 pack see but you only need 1.
6. 1/4" mono Panel-Mount Audio Jack (Catalog #: 274-252)
7. 1/8 Mono Phone Plug (Model: 274-286)
8. 2-Conductor Standard Phone Plug (Model: 274-1544) I think thats the one I got, Its got the picture on the website that most looks like mine, however, I'm sure any 1/4" mono (even stereo but then you'd have to pay closer attention to your wiring) plug would work.
9. Soldering Iron and solder
10. 2-Conductor Intercom Wire (Model: 278-857) Im pretty sure thats the wire I bought.
11. Heavy-Duty 9V Snap Connectors (Model: 270-324) Like the other packages it has more then you need
12. 8 AA Battery Holder (Model: 270-407)
13. 8-Pack AA Enercell® Alkaline Batteries (Model: 23-874)
14. Slim Line 2" Alligator Clips (Model: 270-346)
15. Drill with assorted bits
16. Spare hookup wire (You can cut off some of the intercom wire if you need to)
17. Nichrome wire (Can either be bought on e-bay or Unitednuclear.com) make sure you don't get the wire too thick I use unitednuclear.com, but I don't know what gauge it is.
18. I'm assuming you have tools like screwdrivers and wire cutters.
