  • Extraction is heavily controlled by amount of water, temperature, grind size, and time.

    To get an under extracted brew, you would use more water with a shorter brew time with a course grind at a lower temperature. This should give you something that’s sour, weak, watery, with a thin mouthfeel.

    Overextraction would be the opposite. Boiling water in a preheated brewing device, fine grind, less water, steeped for a longer time. This should taste dark, bitter, burnt, strong, with a soupy grimy mouthfeel.

    You can make one cup of each at the extremes to taste the difference, and then use that information to tweak your regular brew one variable at a time. Look up the coffee compass to help understand what you’re tasting and which direction to move.










  • It’s the internal power supply of a bar of LED garage lights. This one made a loud pop when I wired them all up.

    The pad ripped off the board.

    I was able to fix it by using an empty pin on the same circuit. Soldered a wire through it, then used a butt connector for the input line and the line to the other end of the LED bar.
