Hi all,
I am building a project that requires an automatic intermittent ignition source. One option I have is to periodically (about every 20-60 seconds) create a spark over 2 or 3, one to two inch gaps. The discharge can either go back through the circuit (sorry if I am not using the proper terminology) or be immediately grounded via a metal piping system (i.e. jump from circuit to the ground). What are some ideas on as simple as possible ways to achieve this?
1. I prefer to use 110V A/C source unless a cheap, long lasting DC source will suffice (i.e. AA battery powered which can last 10+ hours of sparking).
2. Easy and cheap as possible.
3. I would like to make this as safe as possible (my friend and I will be working very near the spark gap paying attention to other things).
4. If multiple spark gaps complicate things I can live with one.
Thanks!
Dan
