Question about voltage regulation and compressors

[bernierunns]

I built a Bear Hug compressor and posted about debugging on here when it didn't fire up right away. A fella mentioned in a reply that when I do get it working that I should probably run it off a nine volt battery because it is pretty sensitive to current and voltage fluctuations. Is there a solution to regulating voltage and current with a voltage regulator? Am I way off base?

I would run it off a nine volt but it is stuffed in a box with a Big Muff and there is just no room for it. The BMP sounds great but the compressor spits and farts. Maybe I don't have the circuit worked out yet. Although it sounds pretty nice when tested with a nine volt.

Anyone?

You say it works well with a battery, but spits with an adapter. Is the adapter regulated? That's what I would try first. If you don't have a regulated adapter, it's easy to use a cheap, unregulated 12V DC adapter, a 7809 or 78L09, and a few caps to get a steady, noise-free, regulated 9V.  Let me know if you need more guidance with that.

Other than that, I recommend asking your question on DIYSB. The designer of the circuit is very active over there and will probably be glad to help.

Thanks for the reply. I'll head over to DIYSB and see what i can dig up. I might be back for some help with a regulated power supply though. By the way Induction, thanks for the help getting this compressor to work the first time through.

My pleasure.
