Ever wanted to visualize your brain activity? Electroencephalography (EEG) uses electrodes placed against the scalp to detect the tiny electrical changes that occur when neurons fire. By amplifying these signals through a computer, you can observe brain activity in real-time.
It's really easy to program AVR microcontroller chips — but some of them don't fit the standard Atmel programmer. You need an adapter to connect the Atmel ISPMKII programmer to an ATtiny24 microcontroller Dual Inline Package (DIP) chip — and you can easily make this adapter with just a few components. Here's how.
Have you ever wanted to sculpt something out of ice? Here's an easy way to do it with a "hot wire ice cutter"
Build a low power watch from off-the-shelf components and breakout boards
After years of failed attempts with store-bought traps, we realized we had to make a trap as clever as the rats. In our Smart Rat Trap, the Arduino reads a proximity sensor, then powers electromagnets to drop a cage on even the cagiest of uninvited furry guests. Build it!
In this project, I am going to give you a basic introduction to 3D printing pens and how to use them
Think back to your first wearable tech experience: maybe it was the communicator badges in Star Trek, the palm flower crystals in Logan’s Run or the man-turned-machine in Terminator. We want science fiction to be real because we want to feel special, aware, and powerful. That’s why wearable tech is our now, and the Flora microcontroller is our BFF.

Ordinary kaleidoscopes must be pointed toward a light source to work. This one has built-in illumination, so you can hold it right up against a printed page.
This 15th-century English nun wrote the book on the technology of recreational fishing.
I decided to make programmable version of The Clapper using an Arduino microcontroller.
Vintage components that add character to your creations.
