I'm sure a ton of people have asked, but I can't seem to find any threads about it here. Anyway, I want to take the plunge into pneumatics. I found an air compressor on eBay. It is a 12V 300 PSI portable air compressor. Also referred to as a tire inflator. I'm sure it has some use in pnuematics, but I'm also sure it has its limitations. Since I'm new to haunting with air (in the process of reading the tutorial on Phantasmechanics) I don't plan on doing much more than simple pop-ups. Also, I can't afford expensive relays and controllers and that sort of stuff. I plan on using scrap material for armatures and frames. Anybody use these comressors before? Should I save my $6? Thanks.
