I use 16 gram CO2 cartridges for emergency filling of bicycle tires. Saw a gun designed to incorporate them into use on computers and bought it. It is kind of week, short lived and expensive @ $2.5 each. Hadn't considered the environmental aspect. But it is rare-use. Also have a vacuum cleaner attachment for keyboards. It has 23 tubes, 3/16 x 4 inches, with tiny brushes on the ends. Looks like a strange sex toy. Can't remember where I got it. Surprisingly, the silicon rubber tubes are still very bendy. Works really well but I don't know about components with the brushes. -- Kind Regards, Freeman -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
