Hellow fellow

This device is perfect for your home experiment about security in Hydrogen made by electrolysis, it (like in description picture) hold a flashback to the place where is generated the flammable gaz.
THis device have been personnaly tested with Hydrogene and Acetylene and i find it pretty wonderfull but knowing people struggle about that part and (as i used to fail and explode a Hydrogen tank in front of me) i decided to make this security device and publish it.

This is composed with 4 parts, two

"Couvercle vissable base gaz" and "Type 1 et 3 vis de couvercle vissable gaz" are the two part that fit together for the flashback, the long tube is the entering gaz and tho second hole is for the outgoing, gravity hold back water on the bottom, the long tube must go 4 cm under the water level for making bubble that preserve direct contact if gaz burn, the more water there is, the less will burn and may explode if confined if the gaz flashback
If you don't have bottle you can simply print the "Type 2 couvercle vissable bouteille" that is a bottle for the bubbling and don't need to print "Type 1 et 3 vis de couvercle vissable"
Both are tools that permit for the first let you parameter the file for your need.

Simply take a jar and drill a 35 or 36 mm diameter hole at the lid. Use glue or sealant between the two part when screwed to be perfectly sealed

The parts : "COuvercle vissable basecable,gaz" is if you want directly for the generating case where you produce your hydrogene, it have 3 holes, one big where you can hotglue or glue a tube for the gaz, the two little holes are for the cabling with positive and negative born for the electrolysis. Don't forget to use a decent cable diameter if you have a lot of plate with a lot of surface if you don't want to overkill it :p
It fit with the Type 1 et 3 couvercle vissable" inside the container.

Hope those tools that are really cheap make your hydrogen and other flammable gaz project more accessible friendly :)

Don't forget if it help you or find it interesting to hit like, i'm oopen for all the question you can have.
