Greetings! The Selfie Mission, conceived in 2013, started with simple experiments. Over a multi-year period, the design and payload emerged into something flyable. I invite you to read this brief

interesting

Hi Hank, The regulator doesn't seem to regulate, it is about 30psi out. Turning the knob on the front makes it open or close/stop the flow of Hydrogen. Maybe it never adjusted, it just seemed right

No need to spend more than about $100. Some regulators have to be built using special materials (like those for corrosive gases), but hydrogen and oxygen regulators are built the same and I have

Carlton, That's exactly the model Larry is looking at! It's listed by Smith as a single stage by the way with a 3 year limited warranty. Not likely you could find a two stage regulator, new,

One regulator to avoid might be Smith 30-100-350 It is a 2 stage regulator I bought off Ebay a number of years ago probably 2013-2014. I think i paid $45 + shipping for this regulator brand New in

Larry, On Amazon now it's $26.94. You can go lower than that on ebay right now.

hydrogen cylinders and regulators use a CGA-350 connector. https://www.concoa.com/cgachart.html

On this list right hand to left hand adapters have been discussed and bought by several groups. There were even part numbers specified, IIRC. That way their tried-and-true helium regulators didn't

That $500 price is totally nutz!!!! I can't imagine what device they have in mind. Just for grins you might ask them for a catalog sheet, or a make and model number. You can easily beat that $93

Yes, mine is adjustable. You definitely want that for pico balloons or a flow restrict or because they take so little gas.

I'm no expert on regulators so I'm hesitant to give an opinion. If you can find reputable reviews for this brand, it should be just fine. Mine is a well known brand thst I bought on ebay that wasn't

They key is for H2 is left hand thread. AND even for safety the pressure it can take. that one looks good in both cases. NOW the one we have been using 30+ years of

This one looks adjustable. I spent far less at my local welding shop for a regulator with fixed settings. Are you asking for an adjustable regulator? I think mine is permanently set for 30 PSI exit

I keep having to ask you questions. Well I appreciate your help anyway. So we are trying to shift over to hydrogen and the local welding supply place wants $500 for a regulator. Yet I see this $93

Yes which video you may also want to call nick Cell 337 258 2527 Helping UL become a world Class Engineering and Educational School Disagree I Learn

Mike ... Could I ask you some questions off line about how you streamed the video? Larry KJ6PBS

Hydrogen is the way to go. Avoid closed spaces and sparks! Jayant

I called and he assured me it was pure helium. ??? I can't see another explanation why it didn't lift. Anyway after checking the cost of gas and the cost of conversion .... Hydrogen here we
