Trivet Light

    One of my favorite places to visit often is the Ballard ReStore.  It is a reclaimed building supply place.  A non-profit.  And they also do a good job of passing on some of the odder things found when pulling down old buildings.  They will at times have old meters or photography or lab equipment in addition to the windows and doors and cabinets and other more normal stuff.

    Anyway, one of the sort of interesting things they had when i was walking through a while back was plastic bathroom tile.  These are 4″ square slightly translucent swirled plastic tiles.  I wondered if LEDs would look interesting shining through them.  So I bought 4 of them.  This is another nice thing about this place, the boxes are generally all open.

    So I took two of these tiles and framed them with some random wood i scrounged from my back yard and made a sort of trivet out of them as you can see on the right.

    Then I took some tricolor LED modules I had and an ATTiny85 and some FETs and added some internal lighting.

    This was my first time playing with an ATTiny, and my first time actually ‘producing’–as opposed to breadboarding–an AVR based device.  I used an annoying prototyping method I had seen mentioned on the web.  I will never try that again.  Ick.  Anyway, here is the board

    Trivetlight all soldered up. And here is the back of the board Solder side. showing the insane prototyping method involving enameled magnet wire.

    It works.  I would like to add some batteries and an inductive power pickup to it so the power cord could be hidden under the table.  Also the plastic tiles are somewhat too opaque, so something clearer would be better.
