    Reed-Solomon code on a chessboard

    Prisoners smart enough to use Reed-Solomon code with rate 3/7 bits/symbol and erasure probability > 13%, not smart enough to use a subset of inputs to get rate 2 bits/symbol and erasure probability = 0?

    Odd one out

    A because all the other shapes are convex, B because it has no right angles, and C because it only has four sides? How am I supposed to know what criteria to use?

    Musical Christmas lights on Arduino

    (Signature) | Video released under CC BY 4.0.

    The nice thing about Christmas holidays is that you actually have the time to make shower thoughts a reality.

    Materials

    • 1 × Arduino Uno. It will also work on other Arduinos (subject to pin number changes), and should also work on other boards, as long as there are 3 digital GPIO pins that can sink ~30mA, 1 PWM output pin, and a 5V rail.
    • 3 × red LEDs, 3 × yellow LEDs and 3 × green LEDs. I’m using whatever comes with the Arduino kit. It should work if it drops ~2V drawing ~10mA each. The code can be easily adapted if you want to add more colours, as long as you have three LEDs for each colour.
    • 3 × 100Ω resistors. I don’t have them so I’m using two 220Ω resistors in parallel to replace each 100Ω.
    • 1 × passive buzzer or speaker. I’m using a KC-1206 which came with the Arduino kit, but I’ve also tested an AST-030C0MR-R (which came with the Chaotic Oscillator kit) and a 4Ω 3” speaker (part number starts with EAS8 but the rest is illegibe due to rust) which I scavenged from an FM radio receiver.
    • A breadboard and a bunch of breadboard wires.
    • A power supply. I’m using USB.

    Code

    A score for the song was looked up and its melody was written out as an array of the standard pitches in int song[]. int durations[] has the same length as song and denotes the relative length of each note. int durationScaleFactor controls the tempo of the song.

    Arduino code: xmas.ino (Signature), pitches.h (Signature).
