Merry Christmas from DoES Liverpool (plus an Oscilloscope and an Arduino Due…)

‘Twas the night before Christmas… okay, it was the night before the night before Christmas when this happened, but that doesn’t sound so poetic, and I’m writing this blog post on Christmas Eve…

‘Twas the night before Christmas, and all through DoES Liverpool not a creature was stirring, except for a couple of hackers tinkering around.

Mathew Carr had called into the space in search of an oscilloscope and an Arduino, so he could try out some code he’d been slaving over at home. His initial plan was to run it all on an Arduino Duemilanove using two of the PWM outputs, smoothed with capacitors, but we couldn’t find any of quite the right value to generate a good output.

So, plan B, which was to switch to using an Arduino Due, which has two digital-to-analogue converter channels to produce proper analogue outputs. That worked much better, as you can see in the video below…

Merry Christmas from DoES Liverpool!

  1. Merry Christmas and a very Happy new year to all of you!

    I showed this to the young people we had here at Christmas and they were excited, amazed and impressed. See you soon.

    1. Cool. You should send them along to Maker Night sometime 🙂

      Hope you had a good festive season – see you soon!
