Controlling dangerous things safely

Fire When Ready – A Pyro-Electric Safety Primer is a great document on issues around controlling dangerous things electrically. The document tells the techniques used on pyro/fireworks electrical control. Quite similar practices are used in other control applications where potentially dangerous things are controlled using electrical circuits or electronics.

    Pyrotechnics sequencer with wireless trigger

    This device will light fireworks in sequence with a wireless remote. Version one will have 64 positions

    With it, he will be able to setup all the pyros during daylight, then arm the system at show time and sit back and enjoy the show at a safe distance with the rest of the party using a simple remote to ignite fuses in sequence.

    Inside a special effect pyrotechnic “robotic”.

    If you’ve ever seen a film where electrical things like spaceship control panels and robots were blowing up and shooting out showers of sparks, then this is probably what was being used to create the effect. It’s a simple pyrotechnic device that is designed to shoot out a shower of sparks when triggered.

    Aladdin Lamp Shoots Flames With A Snap Of Your Fingers

    Despite their dangers, even Marie Kondo would not convince us to abandon flamethrower projects because they literally spark joy in us. To make this flame shooting Aladdin lamp [YeleLabs] just used a 3D printer and some basic electronics.

    The lamp body consists of two 3D-printed halves held together by neodymium magnets. They house a 400 kV spark generator, a fuel pump plus tank, and a 18650 Li-ion battery.

    Although they proclaim that the device is a hand sanitizer it is probably safer to stick to using soap. The project still goes on the list of cool flamethrower props right next to the flame shooting Jack-o-Lantern.

    Programmable firework firing system with remote

    This project is using the Arduino Nano and WS2811 LEDs for a 50 channel (cues) remote firework firing system.
