About $200 US with for everything you need to get it running. I have found that some of the more expensive parts go on sale from time to time. I actually built mine for around $140. The Infrared flashlight will cost about $50 with a battery and charger and the micro DVR cost $12. Not much considering the thousands of dollars you could spend on a new NV optic.

I'm happy to answer any questions!!! FIRE AWAY!!!

Your kinda right. PLA is generally considered safe and you can buy specialized PLA that is food grade. But PLA will dissolve over a long period of time which is a disadvantage (obviously). PET and PETG I'm pretty sure are food safe. ABS is for sure not food safe and the chemicals can be absorbed into your food and mouth.

yrralguthrie Did the rock contain any gold? It might have been gold just extremely impure. What is your point you are trying to make? Are you saying that a mixture of hydrogen and oxygen is not allowed to be referred to as oxy-hydrogen or HHO(which makes sense) or hydroxy gas and should only be referred to as "H2 + O2" or "oxygen gas hydrogen gas mix"?

I call it oxy-hydrogen. Just like a mixture of acetylene and oxygen is generally referred to as oxy-acetylene. It doesn't have to be a defined mixture to exist.

Yeah, a trigger mech would be nice. My air compressor is one of those big upright industrial ones. I think it is about 180-200 in the tank but its regulated down to 120. I do have a bike pump as shown in the video that makes it up there to 160ish but its held together with JB weld because some of the plastic parts broke from that pressure. Would like to get one of those PCP pumps but to much pressure will fold the seal of the dart, making it less powerful. Something I found out trying to shoot these with a homemade oxy-hydrogen gun.

Checked out your video and it looks pretty good! I actually have oiled the ball valve and "broke it in" so there no resistance. Furthermore, I have placed the ball valve in a spot so it is pulled easily with one finger allowing you to keep both hands steadying the airgun. Still, it does take some practice to pull the valve fast enough and it might be handy to put some trigger system like yours on it. Oh and the black iron pipe is rated for 750 psi. Yep. And that is seamed black iron pipe. Seamless black iron pipe can withstand pressure well past 2,000 psi. Although I'd probably have to change out the Shrader valve and the ball valve before putting any more the 300 psi in it.
