Mine is called Glow and was adopted by me in August last year!
I need to use Oxygen for my torch and this is the safest (and cheapest) way for me to do so, rather than using an oxygen tank.
Glow is a 5L refurbished medical oxygen concentrator that uses air and coverts it into oxygen to feed into my torch. He makes a noise when he's working, so he's not a quiet bead making companion by any stretch of the imagination but it's a noise you get used to!
He has a pressure guage so I can check that he's breathing properly, and much like getting a torch it was all a bit overwhelming to start with, but now he's my trusty beadmaking buddy.
When I brought him home I even strapped him into the seatbelt of my car to make sure he didn't get hurt on the journey home... any sane person would have just have had him delivered rather than chauffer him door to door, but who wants to be sane?
Do you have a non-human trusty companion whilst you work?
