Raspberry Pi Food Helper, LED Facemask, New Arduino, and more!

<p><span style="font-weight: 400;">Welcome to the Electromaker Show episode 60! This week we look at a reverse-engineered LED audio-reactive mask, a Raspberry PI powered purity checker for food, a new Arduino board, and more! Oh and we announce the RasPad 3 competition too!</span></p> <p>As I mentioned in the open, the audio is a bit weird this week, the quality is high but there are some dropouts due to a badly behaved gate! Shouldn't be a problem going forward.</p> <p><iframe title="YouTube video player" src= "https://www.youtube.com/embed/0SjUDn8sO5A" width="560" height= "315" frameborder="0"></iframe></p> <p><span style="font-weight: 400;">Watch the show: <a href= "https://www.youtube.com/watch?v=0SjUDn8sO5A">https://www.youtube.com/watch?0SjUDn8sO5A</a></span></p> <p><span style="font-weight: 400;">Housekeeping:</span></p> <p><span style="font-weight: 400;">We publish a new show every week.
