A Simple and Cheap Dark-Detecting LED Circuit
![]() | ![]() |
![]()
In this article we show how to build a very simple– perhaps even the simplest– darkness-activated LED circuit. To our LED and battery we add just three components, which cost less than thirty cents altogether (and much less if you buy in bulk). You can build it in less than five minutes or less (much less with practice).

Looking back at Maker Faire
It has been reported that Maker Media is shutting down and that Maker Faire is at its end. Evil Mad Scientist has its roots in Maker Faire, and has been presenting there from the very beginning, so it seems fitting to look back at our Maker Faire projects now. For the very first event in … Continue reading Looking back at Maker Faire
A round up of our “Basics” articles
Over the course of the past few years, we’ve been writing occasional “Basics” articles, about introductory topics in electronics and microcontrollers. In the spirit of making things easy to find, we’ve now tagged them so that you can find them with this link, and we’re collecting them together in this index that will … Continue reading A round up of our “Basics” articles
Halloween Projects from Evil Mad Scientist Laboratories

Make A Cylon Jack-O-Lantern
![]() |
It’s a pumpkin! It’s a Jack-o-lantern! It’s an electronics project! It’s… a Cylon!
For halloween this year, we made Cylon Jack-o-lanterns in both large and small versions.
This week’s Weekend Projects Podcast at Make Magazine is about making a programmable LED pumkin. Our Cylon is made with a very different approach. It runs on a 9V battery and uses two cheap integrated circuits (a 555 and 4017) that together control six LEDs (or six groups of LEDs). |
