Hate to betray my technological ignorance.... but what’s the difference between each of the different downloads ? What equipment requirements are there ? Do I need a certain computer to watch streaming ? Is it limited to my phone, or is there a way to watch on my tv ?

Thanks

Excellent info from Peter Van derBerg himself. Way more complex info elsewhere on net to explain in greater detail, if I can find it  http://batchrocket.eu/en/building#belltheory

As a result, the gases could be pushing back and forth at that port, ebbing and flowing as pressure builds back and forth. Ultimately, the added draw from the chimney helps the gases escape in the positive direction. But, it could be leading to the pulsation Till you give it the extra air flow it needs to push thru

Shouldn't it instead be, each successive port should be higher than the preceding, so gases reach the next chamber entrance before the preceding, so no backflow ?

Hey all, haven't kept up on this for awhile due to life being busy, nor ha I read every comment. So, maybe this was already discussed or I'm remembering incorrectly. But aren't the ports between chambers positioned wrong ?

The drawings show port from chamber 2 to 3 being higher than 3 to exhaust. So stratified gases are trying to backflow instead of easily continuing thru the exhaust path.

Enjoying this project a lot, thanks for sharing !

Curious tho, why all the work for the octagon instead of a circle ? Turbulence ?

What's you're performance like ? I don't see any air intake at the front, nor the secondary "peter-channel". My understanding is, those are necessary for truly excellent combustion....
