Hi Forrest

I can only imagine its a cooker in California or places like it, certainly a air condition unit would be a challenge to fit

Viv

My first thought on seeing that was "Wimshurst machine" but then I noticed the crank and thought WTF a reciprocating Wimshurst machine :-) Very interesting find that, I enjoyed looking it up and realizing it was capacitive commutation, here are a few links for those interested in further reading Ben...

Yes I think the Swedish one with the pop up stabilizers is the better solution for peace of mind, I would still have that terrible urge to put my feet down every time I stopped though

Viv

Hi Forrest

Ouch! those training wheels are not a good idea at all are they ;-( I wonder what happens at high speed when they touch down on a corner? not good I imagine

Viv

Haha great photo

Viv

first can someone tell me if you vaporize gasoline and use it instead of propane will it work? if its does will you get more thurst. second And I know this might be stupid but at the temp a pulse jet works while its running if you vaporize water and inject it in might it work like nos in a car the ...

Hi Metiz

Nice run on that engine, very clean and solid

Viv

Hi Forrest

I think I know the one your talking about, is it this http://www.monotracer.ch/ I have seen these before but not the one above, that was a new one to me

Viv

Drag, turbulence, thermodynamics, these are just some of the things that get in the way of what you want to do, consider for a moment that a Ram jet is an energy exchange device, you are swapping the speed of your incoming flow for pressure then adding heat to it, and then expanding it out through a...

Its just a link spambot Linus, ignore it Mike will delete it when he gets time

Your probably familiar with the small BD5 micro jet airframe as it has appeared on here a few times (I have posted some pictures from Bagotville airshow previously) but I was surprised to see a motorcycle variant appear on one of my favorite motorcycle web sites. The bike is called a Bede BD-200 Lit...

Remember you want an ignition that won't kill you if you should accidentally become part of the high voltage system. Pulsejets are very distracting and it only takes "one time" to forget your concentration with a lethal voltage as mentioned in this strobe article. "Since the circuit operates at gre...

Hi Zono

Keep it simple and go for the transistor ones as it will be easier for you to interface than the triac versions (better for high power operation in PSU)

Viv

@metiz: I think 1...2 Hz. Filling is the bottleneck. @Viv: thanks, opto-coupling is expensive, but you are right! Best for safety. zono Hi Zono Sorry expensive? are talking about the same thing, should be cheap as chips. http://en.wikipedia.org/wiki/Opto-isolator http://www.electronicrepairguide.co...
