I am building a RF controlled flash pot for a magic trick. I have a 1 channel coded Rx/Tx that controls a single relay (momentary switching). When the Receiver gets a signal, it triggers a relay which provides power to a glow plug that ignites flash paper in the prop.
Currently I am using two independent power sources (9V batteries), one for the Receiver, and one for the glow plug, and it works fine.
However, I would like use just one 9V, but I'm running into a problem. When the receiver is triggered, it switches the glow plug on, which then draws so much current, the receiver shuts off! Of course as soon as the receiver is off, the relay opens, which then makes the receiver turn on again, which starts the thing all over again. This on/off happens at about 15 switches a second, so the glow plug never gets hot enough to light the flash paper.
Is there a way to do this, or should I just stick with the two independent power sources?
Thanks,
Clinton
