Ouija Be Mine? Here’s an animated pop-up Valentine's card you can make in a few minutes. When you slowly open the card, a hand sweeps across and moves the heart-shaped planchette over the Ouija board, spelling out the message: “HAPPY VALENTINE’S DAY!” It’s both mysterious and romantic, perfect for any secret admirer to make and send.
How you can use a Joule Thief to charge batteries with low-voltage power sources.
Here’s a little project that we’ve been working on for a long time: a custom-painted leather flight jacket featuring the “Classic Lego Space” logo. If you’ve ever wanted to make your own painted leather jacket — whatever the theme — here’s how to do it.
Fabricate an incredibly small and capable vibrobot using a handful of components.
What do you do with coffee filters after you brew your coffee?
Just for fun, I designed my own variation of a treasure hunt game
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
