How do I build an extremely cheap, easily mass produced delay for my fireworks effects?
sec, 0.25 sec, 0.5 sec), 'power in' connections, and power out connections. We use 22 gauge wire for our power feed from a 24V source. I am looking to make these delays no larger than 2"l x 2" w x 1.5" h not including the delay set knob. As an example - Instead of 10 comets firing off at one time, the delays would allow me to set them off, say, half a second apart. Is there a cheap reliable product already out there and available? Can I take resistors of different ohms and just twist them into the wire? Thanks for your assistance!
