Multimeters are great for determining if there is a connection between two points, measuring the voyage between those points, determining resistance, measuring transistors, and much more depending on the type.
Tia’s distortion is pretty cool. It almost sounds similar to a fuzz face but it’s slightly cleaner—almost closer to a tube screamer. Oh wait. It’s based off the Boss DS-1. That makes a lot of sense. Also I have the same color guitar.
Jaye’s polysynth is really awesome. I’m definitely interested in oscillators and polyphony. I’m especially interested in the incorporation of an LFO to control the VCA.
I really like Ryan’s use of an envelope follower to control a tremolo circuit. The use of an input which can change rapidly to control another aspect of the output is something I’m definitely interested in.
Oops I forgot the thing about breadboards.
Breadboards allow you to connect multiple components together by simply plugging them into electrically connected rows. The two columns on each side of the breadboard are electrically connected creating power rails. As for the ones in the center, each row of holes is electrically connected across horizontally up until the (horizontal) center of the board. After that point the rest of the holes in the row are connected. To put it simply, after the two columns at the right the first five holes are connected, and are separate from the next five holes which are themselves connected. The two outside columns on each side are all individually connected from top to bottom.
