Flickering Jack-O-Lantern #ElectronicHalloween

Charles Merkel posted about his project in the Adafruit forums and shared this video on Youtube!

Since my last post regarding the Jack-o-lantern, I have rebuilt the device to allow use in other projects. I removed the header pins from the trinket and installed a two pin connector for the power. The jewel is connected to the trinket with two buss wires and the 220ohm resistor for the data input. I used sleeving on the other two leads. These wires are flexible enough to allow the jewel to be positioned as required. Then I mounted the electronics to a 4AA battery box that has a switch. I cut a 1.5in hole in the bottom of the pumpkin. I then mounted two sets of velcro strips to the pumpkin and to the battery box. The trinket is held to the battery box with tacky putty. I adjusted the jewel so that it favors the back of the pumpkin. I also added a diffuser tube over the jewel to soften the light. The diffuser is nothing more than wax paper rolled into two layers. The pumpkins came from Walmart and are mostly plastic and foam.

I am living proof that the Trinket will work but please don’t ask me how I did it. I had most of the troubles others have described here but apparently even the blind hog finds an acorn once in awhile!!!
