Digital Stethoscope

Thinklabs has the first stethoscope where you might need to say “iPod not included” when showing pictures of it. Although the $495.00 version does come with a 2GB iPod. Think you could build your own? You probably could, here is a reference to use as a head start. “In a conventional stethoscope, the diaphragm vibration causes air pressure behind the diaphragm to change, which passes up the tubes as a

Air Cannon,  Coil Gun, Exploding Wires, Can Smashing, etc

Hacked Gadgets friend FastMHz has been busy doing all sorts of experiments, and this crazy mad scientist has captured it on tape for our enjoyment! Not sure if all fingers and toes are still accounted for, I think I would be hiding (cowering) behind something solid for most of these tests. 🙂 After watching the video those wall mounted can crushers seem so useless, I want to crush cans using

LED Matrix Information

If you want to play with some LED matrix displays Nuxie1 has written a guide to help you get started. “An LED Matrix is an array of LED’s with the anode or positive terminal of each row connected together, and the cathode or negative terminal of each column connected together. Or the anode can be connected to a column, and cathode connected to a row. Using just a microcontroller with

A look inside various integrated circuits

If you have a burnt out IC (integrated circuit) why not crack the thing open to what makes it tick before tossing it in the trash. Nick Chernyy from uBlog has provided some details on how to do it. Just so happens that I cracked open a power regulator myself not too long ago… “Integrated circuits are very hard to design properly, so many people put substantial effort into doing

Top 5 Coil Guns

Here is a list of 5 cool coil guns, either one would be fun to try out. Remember that coil guns can be dangerous, if you build one and shoot out your eye don’t say you weren’t warned.

PIC16F88 Delorme Tripmate GPS Logger

Using an old serial GPS the guys as Semifluid have made a home made GPS data logger on the cheap. As usual schematics and directions are on the site. “This project focused on creating a simple serial data logger for the Delorme Tripmate (also known as the GPSTripmate). The Tripmate is an older GPS receiver that can be purchased on eBay for

Audio/Video Cabinet Fan Controller

John Carter made a nice AV fan controller for an audio/video cabinet. There is code and a diagram of the design on John’s site. This project uses the PIC AXE microcontroller, if you want to play with some of these chips I hear that Peter Anderson is a great resource with cheap shipping. “This is a fan controller for an audio/video cabinet. It uses a PICAXE 08M and a DS18B20
