Happy Halloween! I’m in the mood for an extra, and I’ve got some stuff that’s been turning to zombies from the tipline.
Pictured above is a nice simple LED pumpkin sent in by [John]- perfect for the hacker with less than stellar art skills.
Let’s not forget [mastershake]s Hack-A-Day pumpkin from last year. Where’s the THAD pumpkin you promised? … Read the rest

Ion Cooler 3.0 (return of InventGeek)
October 30, 2007 By 30 Comments
[Jared]s been taking a bit of a hiatus, but he assures me that he’s gearing up for a bunch of new projects. The first sign that he’s awakened from his slumber is his latest take on the Ion Cooler. This time he’s built a CPU specific version. The cooler is made from off the shelf materials – heap pipe heat … Read the rest
DIY Ultra Wide Band Radar
October 29, 2007 By 23 Comments
[Andy] sent in this pdf (mirror) describing a simply diy UWB Radar project. It’s not intuitive, but by using a wide frequency range for low power, short distance purposes, the system should avoid interfering with other radio systems. The paper has a complete circuit schematic, and offers some suggestions for adding communications to the signal. Unfortunately, to really … Read the rest
USB Gameboy cartridge project

Speaker as a microphone
October 27, 2007 By 22 Comments
[Nathan] sent in his speaker microphone project. Speakers and microphones are physically similar – usually mics are much smaller to allow decent high frequency response. In this case, [Nathan] wanted something to pick up kick drums or bass guitars, without the cost of a commercial version like the subkick. It’s build around a dual coil 6.5 inch subwoofer. … Read the rest
Stroboscope LED fan clock
October 26, 2007 By 7 Comments
[sprite_tm] sent in one of his latest little adventures – and I love it. To create his stroboscope fan clock, he put a couple of red and green clock hands onto a standard PC fan(I love Panaflo fans), then he built a circuit to strobe a RGB LED to create a set of virtual clock hands on the spinning fan. … Read the rest
