Help Needed: Power Supply

by terencework7 on Thu Oct 22, 2009 1:54 am

Hi guys. Sorry. I'm really a amateur at this. MOre of a beginner actually, in terms of electronics, but i'm really determined to build this! So please be patient with me.

I wanna make sure I have all the tools and parts before I start working. So, here's the problem... On the preparation page, http://www.ladyada.net/make/wavebubble/prep.html, it says this:

Power Supply
It can be a thousand dollar arbitrary waveform generator, or a 9V hooked up to an LM317 & potentiometer. Whatever, just make sure you can get ~3-4 V out of it, for testing.

Of course i don't plan to get the thousand dollar arbitrary waveform generator, so I looking at the 9v thingy... But what exactly is this 9v? Is at a 9v adapter? Or is this the thingy i have to build in the sidetab that says power supp. Maybe attaching a pic for me wld be good. Thanks ALOT!
