Why buy test equipment when you can make your own? Edwin made a capacitance meter using a PIC16F873A as the brains. If you want to make your own there is code and a schematic provided on his site. “This is an autoranged version, which means one does not need to adjust the range settings. Furthermore, the measuring range is quite large, from 5pF all the way to 2600uF. It is
The Jack-o-LED project lights up a pumpkin with color changing LEDs. This puts the single color pumpkins to shame… “So a couple of weeks ago I was grocery shopping, and on a whim, I bought a pumpkin. I hadn’t made a jack-o-lantern since I was a kid, and I decided to try to do something interesting with it. I found some really cool patterns that I was going to

Full details on how to construct this remote controlled scissor halloween prop is available. The build plans are well done, but it does look like a complex build process. After Halloween you could mount a huge boxing glove to it, I can’t think of a better way to get rid of door to door salesmen who don’t take no for an answer!
Here is a nice LEGO hack that will put a smile on anyone’s face! Seems that a standard 5mm LED fits quite well into the heads of LEGO people. 🙂 “It’s a good idea to carve your head before putting the LED in. (No, not your head, the head of your Lego minifigure.) This is particularly important if you’re starting with an older Lego head, since the suction can make
Instead of going to Walmart and buying some creatures for your lawn why not build your own? “Our gargoyles are hollow rubber skins, supported by an internal skeleton of PVC pipe. Note that the garg is sitting on a “rock” that is also molded into the skin. We’ll put the fogger inside that area. We tucked a fogger under the garg, in the space between the skeleton parts. Ductwork carries
Scary Terry has come up with a Flaming LED Skull project that would be good to greet all your guests on Halloween. Terry also links to this site as a good flaming skull resource. “I came up with my version of the Flaming Bucky. Instead of mounting the fan inside the head, I use a 4″ fan mounted near the ground and PVC pipe to direct the air into the
