Solder wick, coffee, and paper towels keep SparkFun running. You can steal someone's diagonal cutters for a minute, but you'd better ask before touching their solder wick. Solder wick is composed of copper threads braided together. Flux is normally added to help the solder flow from where it is not supposed to be (the jumper) to the wick. Hence, solder wick is sometimes called desolder braid. Yes, you really can solder anything, and solder wick is a large part of the process. This wick is...

This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip is like a rotary switch - it internally routes the common pin (COM in the schematic, SIG on the board) to one of 16 channel pins (CHANxx). It works with both digital and analog signals (the voltage can't be higher than VCC), and the connections function in either direction. To control it, connect 4 digital outputs to the chip's address select pins (S0-S3), and send it the...
