Budget/Refrigerator grow
I don't like household wiring, AC, analog, or anything like that, but I just now got done with an analog class in school. And I generally know how to deal with it all.

Getting just the right amount of feedback, and canceling all the noise was really tough.
When it comes to digital, I know what the hell's going on. I can design just about anything with logic gates.
And yeah, shake, Music theory test this morning at 8am.... hard to believe I'm still awake. haha.
I have two primary pieces to buy now, a timer (which won't really be needed till later, but I'm thinking about giving em 20/4 or 18/6) and even though I went back to lowe's, and home depot, I didn't walk out with a thermometer...
