Here’s a cool DIY on howto build your own heart rate monitoring device using an Atmel Atmega8 microcontroller. You can probably easily make this idea work with any other microcontroller out on the market with an ADC.
After a little introduction into ECG we will move on to the electronic description. The simplest way to explain how it works is to make a block diagram! The signal from the body is being amplified(the signals from the body are small and weak, ra
Check out this cool DNA extraction using everyday materials! Although I am no where near a genetic scientist, this might be something I can try… (So I can find out which dog left their pee mark on my walls…)
DNA extraction and separation by agarose gel electrophoresis is a simple and exciting process that anyone can perform. However, the high cost of specialized equipment and chemicals often hinder such an experiment from being carried by members of the high school community. Here, we describe a cost eff

Here’s a cool little science experiment to put out some fire.
Wow, here’s a cool way to make some etched candy box for Valentines day using some everyday hacker’s parts!
Speaking of killing you, as we are using water and electricity here, please be supper-duper cautious. I can’t be held responsible for burned fingers, house fires, dead cats or any combination thereof. Please use some common sense!
This is a decent project that should cost you little or no money, depending on what you have laying around the house. The idea is to u
Wow, check this out, you can make a cloud lamp using your old vodka bottle! cheers!
Here’s some cool looking homemade brushless motors made using some PC Hard drive parts and power tools…. wow!
My first home-built outrunner motor from hard drive stators (Western Digital Caviar). Motor designation is 280-10-6 as it has a 28dia x 10mm long stator. I used 6 windings of 3-strand 0.35mm wire with a delta connection and a distributed winding pattern. It spins 12,300 RPM @ 23.3A with a 8×4 Graupner SLIM prop.
This 350-20 is the biggest motor I’ve built so far. The 12-tooth

I’ve been witness to some retro Atari’s you can buy at Target for like 30 bucks. Here’s some cool kits you can actually put sensors and make it act as an MCU.
AtariLab is a sensor kit for the 8-bit Atari computers. I ordered two of the kits recently, the starter kit and the light kit, and they both arrived in pristine condition. They work great with the Atari 130XE, but the light sensor was giving me some random readings (replacing the photoresistor in that wouldn’t be hard). The breakout board attaches to the
Here’s a cool little design for your future FM transmitter. (I’ve built similar ones before, the challenge is, can you build one that’s stereo and noise-free?)
Using the simple designs of Tetsuo Kogawa, Japanese engineer famous for “party radio” and “polymorphous radio,” Neighborhood Public Radio will spread the gospel of micro-transmission in a 3-hour build your own pocket micro-transmitter workshop. Bring your soldering iron (if you have one) and an Altoids tin… and Ne
I just ran into this balancing bot kit. Kinda pricey but cool that you can get one. (Can we get some samples?)
Now, you can build your balbot using this kit instead of starting from scratch!
The BalBot Advanced kit includes everything the Basic kit does, PLUS the BrainBoard microcontroller board, 2 forward-looking infrared distance sensors, a programmer, serial cable, C-compiler, and more (see kit contents below for details)!
In short, the BalBot Advanced kit includes all the

Check out this cool orb that has a mini ITX that serves as a HTPC, Fileserver, and HTTP Server! Cool space looking design, maybe a grill was used here… You can make your next media PC like this and put it next to your TV and let your friends admire it.
