    This is actually quite easy to make so long as you can get hold of acrylic / perspex blocks reasonably cheap.
    Parts:
    1. Arduino Uno R3.
    2. 4 x 12 pixel WS2812B addressable LED strips from ebay in parallel attached via 200 ohm resistor to pin 6 to limit current.
    3. Adafruit max 9814 autogain mic attached to pin A0 https://www.adafruit.com/product/1713
    4. 24 x Perspex / acrylic blocks in 2 x 12 sets held together with threaded rods and nuts (each set of 12 has 2 LED strips hotglued to the back so that they light up the blocks).
    5. A 60cm x 40cm stainless steel shelf to sit the blocks on and reflect the light back.
    6. Powered by 12000mAh External Battery Pack (PowerGen Power Bank Backup USB 5v Charger) with 1000uf electrolytic capacitor across +ve / -ve to protect strips when powering up. This avoids using a mains adapter and needing to be near a socket.
    Arduino code:
    I learned how to edit and write the code for this with Programming Electronics Academy – I really recommend this course. I have been playing around with the Arduino for a couple of years but could never really get the hang of coding until I did the course. https://programmingelectronics.com/ Michael James is an excellent teacher and there is a free version if you want to sample it first (check out his youtube videos here https://www.youtube.com/user/OSHJunkies ). I don’t claim to be a coder and this is not the most elegant code you will find but it works.

    a. The code uses the adafruit neopixel library https://learn.adafruit.com/adafruit-neopixel-uberguide/overview
    b. The first part of the code is Adafruit’s own mic code which calibrates the sound level so that whether you’re using a big speaker or, as in the video, a tiny ipad speaker, the mic remains sensitive.
    c. The second part of the code maps the sound level onto 12 if statements so that when quiet it idles with the neopixel library rainbow but then as the sound level gets higher more effects are triggered.
    d. Within each if statement I have then included a random() function so that the display stays interesting.
    e. You can edit each individual strip pixel to create patterns in an infinite variety of ways and using the random () function you can keep on building so you never get bored.
    f. The code works best with music with a wide dynamic range (soft and loud parts).
