Re: Slow Motion Combustion Video
Nice to see this stuff with the high frames per second camera. We've operated for years knowing that multiple spark gaps will allow a more complete and faster chamber burn. Also it was interesting to see the forces and "back waves" of pressure in the chamber even before the potato left the muzzle. A...

Remember this, I don't want to spend more than I really need to. This project is more of a "lets see if I can really do it" and a "practice" project so I can get better with soldering and electrical. Sorry for all the theoriticals here. Car speakers are typically 4 ohms and will probably overload a...

Those 2 x 25w will be more than enough for what he's doing. He's not going down an audiophile trail with this project. He can always go with the 100w model for $20 more if he so desires. I too was skeptical as an old class AB man but Class D amps are now the high end of the high end in the pro sound...

I know, double post but different subject. I find the way they rate amplifiers is designed to decieve. The 2X40 watt amp is listed at putting out 80 watts total, but only draws about 12. :D I like to know that the amp's real power is as measured in RMS watts out per channel with both channels driven...

Yes I do. I build them for my audio and sound business. You'll need speakers, a stereo amp and a power supply, some interconnecting cables and some patience. Here's a good place to start for a modern class D (digital) amp, 2 watts - 100 watts your choice. Can drive 4 ohm car speakers in good shape. ...

I believe keeping a primary focus on Spudgunning is the best approach for the site...basically the world's premiere authority on the subject. I also work in audio/recording and information technology but I wouldn't expect a spudgun site to seriously deal in those areas...even on a hobbyist basis. I ...

Dude I didn't say I was poor. I don't see a point to paying for a professional system at this point or on a experimental build like this one. I don't even know if all the additions will work so pouring extra money into it on a cannon that is purely a testbed is pretty stupid to me. Maybe on the nex...

Propane isn't really cheap. Just to do it I've seen most go for 100 to just get the meter and the parts. Out of the price range. I don't know, I might switch to something else. Gasoline came to mind only because I haven't heard of any that used it. Figured it was worth looking at. Perhaps then you ...
