Health experts advise washing your hands with soap for 20 seconds to reduce the risk of spreading the coronavirus and COVID-19. And over the last few weeks we’ve seen a bunch of ways to help you get to 20 without counting — you could sing part of a song, recite the introduction to a favorite TV show, or even generate a poster with the song lyrics or custom content of your choice.

Or if you want to get really geeky about it, you could build a DIY, internet-connected soap dispenser that plays 20 seconds of music from your Spotify playlist every time you squeeze some soap onto your hands.

The folks at Deeplocal took that least approach, assembling a soap dispenser-activated speaker that incorporates a Raspberry Pi W Zero mini computer, an Adafruit Speaker Bonnet, a bit of tape and wire, and some open source software — which they’ve posted to github for anyone who wants to build their own.

The end result is a musical soap dispenser called Scrubber, which the developer say contains about $30 in parts and takes about 4 hours to assemble.

You’ll also need some wood or plastic to make a box to hold the soap, a soldering iron, knife or scissors, wire cutters, and a few other tools though — so this could get a bit more expensive if you don’t have some of those things lying around.

But having washed my hands roughly 4,000 times in the past week, the idea of a musical timer to relieve the monotony of the process certainly holds some charm.

    1. Wait, that doesn’t sound right.
      4,000 washes x 20 seconds = 80,000 seconds
      /60 = 1,333 minutes
      /60 = 22.22

      …that’s 22 hours + 13 minutes. = 1 non-stop full-day (roughly).
      Holy carp, you’re right.

      He’s either miscalculated, or Brad’s using some US/Imperial number system instead of the International Metric Numerals that we’re unaware of.

      1. That would be 22.21 hours per week, or about
        3.17 hours a day, ,
        or 0.26 hours 15,8 minutes an hour per 12 hour day.
        We assume that Brad Linder does sleep at night.
        Though as you know in Act 5 Lady Macbeth enters, holding a candle, but asleep. Lady Macbeth keeps rubbing her hands as if to wash them while saying “out, damned spot” (5.1.30). Then Lady Macbeth seems to relive her attempt to convince Macbeth to kill Duncan, And recalling her line “A little water clears us of this deed” in Act II,

    2. Me thinks Brad just gave up and was soaking in the bathtub all day with a cigar and a waterproof laptop.

  1. I think washing your hands is good no matter what is coming around. Perhaps if this was routine in every ones life, there would be a lot less diseases spreading around? I think soap and water beats hand sanitizers since I don’t believe germs / bugs would adapt to it.

  2. “About 4000 times” !!!
    There is not a display showing a count-down from 20 seconds!!? Daily summary?
    Hourly reminder? Low soap container alarm?

    And is the soap that dissolves the lipid (fatty) coating of the virus,, spread by droplets (thankfully not an airborne virus)
