Halloween Revisited
This is my first solo SXB code and my first project with an SX28 Proto Board.· And it was a lot of fun.
There's nothing really new here.· Just a twist of a couple projects previously posted.· One is Jon Williams' "Spooky Eyes".· I could not find the other post so if anyone can recall it, please note it here in this thread.· It showed lighting a jack-o-lantern internally with UV LEDs.· The interior was painted with flourescent paint.· It's a very cool effect.
I have posted the code and some photos of the construction.· The hardest part was making the eyes (see photos).· They are made by·glueing a piece of black plastic (1/16" ABS I had laying around) to a clear·acrylic half-ball and drilling out the backside to accommadate·3mm UV LEDs.· The black plastic was cut so that a tab was protruding from one side.· The tabs are used to hot glue the eyes to the jack-o-lantern. I then painted the front side of the acrylic with fluorescent paint.· Then the LEDs were glued in and I painted the back side black to absorb light emitted from the back.
The interior of the jack-o-lantern is lit with four 10mm UV LEDs soldered to the SX28 Proto board.· Each LED has a series resistor and all four are controlled at once through a transistor.· Same thing with the two LEDs in the eyes.

I used UV LEDs for the "Faux candles".

Just kidding, it's good to see you have found time to play around with SX/B.
Cool project, I'd like to see a video too.
