Ken Murphy recently published his wonderful Blinky Bugs as a book and kit and was awesome enough to send us a copy. Blinky Bugs are easy to make LED critters with antennae as blinker switches that activate in response to vibration or air movement.
Chronicle did a very nice job with it–the book itself comes out of the nifty sleeve that holds the kit and book together. The cartoon illustrations by Alexander Tarrant are very clear and there’s a nice assortment of accessories to go with the core hardware.
The bug circuit went together very easily. These little guys are super compact and self contained, which means they’re adaptable to all kinds of uses. And while putting them on pipe cleaner legs is seasonally appropriate, they’re a perfect fit for a mini-pumpkin. The first thing to do after gutting the gourd is to mark and cut the holes for the LED eyes. A 3/16″ bit turned by hand makes a hole that is just snug enough to hold a 5 mm LED firmly in place.
A couple of slits let the LED leads stick up through the body of the pumpkin where the antenna wires will be able to reach them.
Finally, the pumpkin lid is trimmed to allow the antenna wires to move freely.
