Why not pressurize the chamber using the electrolysis cell itself as the pressure source? I imagine it would actually be a very thermodynamically efficient compressor. Heck, you could probably make the electrolysis cell the chamber itself.

Been a while! Had some trouble with the air gap flash- apparently the iphone’s ‘Bulb mode’ is not a true bulb mode. If I can get my hands on a real dsrl camera I’ll get it working. It was fun working with high voltage again, though. Anyway, what I’m going to do now is make my hybrid a bit more, uh, ...

That's really surprising, huh. I guess intuition only goes so far with stuff like this. Also, air gap flash is done. The 20nF, 30kV field distortion triggered spark is almost as loud as the hybrid. It should have a peak intensity duration on the order of a few hundred nanoseconds. The trigger is act...

Whenever I'm in the shop, I got earplugs, safety glasses and a hat on. It was required dress code in the machine shop where I learned and it's stuck with me ever since. Had a carbide router bit crash into the fixture one time at ~12K rpm and launch a fragment into the wall past my head. Hole is stil...

O.O Wat. Just experienced my first hybrid shot. Before I started machining, I figured I should test out my fueling system and sabots first. Threw together some black iron pipe, fired it at 5x and saw the light. According to HGDT, that little dart was moving at right under 2000 fps. According to my e...

Keep in mind that if you go H2 + O2 you are almost certainly going to be experiencing detonations. There's even a very real possibility of spontaneous ignition during fueling. Translation: I wouldn't recommend such. If I was going to take any one person’s advice, it would probably be yours. I’m goi...

Looks like you're going to be busy :shock: That’s exactly what I’m hoping for! That said, I want my busy-ness (definitely not business) to produce something worthwhile, so I want to be smart about this. I have tentatively decided on a 20x hybrid, with the barrel and chamber safe for up to 200x if i...

So, I've been making things that shoot things on and off for a very long time. I was a here lurker when Larda punched some serious holes in steel with that insane 200x hybrid. I made a few combustions, some simple pneumatics and a decent piston pneumatic that I still have. Now, I have a job that lea...
