I attended another pyrotechnics course at the same place as I took my general operator’s courses. The class was focused on proximate fireworks: fireworks designed to be used quite close to audiences and performers in theater, movie, television, concert, and sporting venues.
Flashpots, strobes, comets, crossettes, mines, gerbs, lances, airbursts, etc. Lotsa stuff to choose from. I’ve made and used many of these over the years and had a great time with them. You’d be amazed to see how close you can be to a properly designed and constructed pyrotechnic device…

A concussion mortar. Loaded with an ounce of flash powder and ignited by an electric match, it sounds like a cannon…
Here’s my video of the live fire demonstration given today:
Also demonstrated was a commercial flame projector. Though nothing like the ones that I build, it’s still impressive for the simplicity of the device.

Another highlight at today’s class was my friend Espressodude whom I build stuff with and camp with at Burning man. He has built “The God of Hellfire”, a motorized flame effect platform that traverses a full 360 degrees and elevates from 0 to 90 degrees (horizontal to vertical). With twin “flamethrowers” and an all electric firing system, it is quite possibly the coolest thing I’ve ever seen anyone build in their garage. He brought the flamethrowers out to my property a few weeks back for testing after the fire department asked him not to do it at his house anymore… Today was the first full system test. He had a custom trailer built to carry the self mobile platform that allows operation without unloading.

I’ll share more on this particular project in weeks to come…
