Some people love to launch model rockets, and personally I’ve always wanted to launch a stratospheric balloon up to “the edge of space.” We don’t exactly do the same thing for the same reasons, but there’s one thing we would all love: to have our payload come back to Earth exactly where we want.
The Solar Bottle Lamp is a solar-powered light that reuses a waste plastic bottle by attaching a 3D-printed solar lamp in place of the old plastic cap.
Edge-lit displays typically consist of an etched sheet of acrylic, with one edge embedded in an opaque base containing a light source. The light diffuses through the acrylic to make the etchings glow.
It is a profoundly human compulsion to change our environment to suit ourselves, and the quarter-trillion-dollar US home décor industry presents a playful (and profitable) example: We bedeck our living spaces to express ourselves and illustrate our individuality.

It’s 15 years since LilyPad — learn what’s new and make your first iron-on circuit!
It’s fun to use mini solar cells to charge your gear or power small gadgets, and once you’ve learned the basics you can scale up to bigger panels. Let’s explore ways you can harness solar energy for your own DIY projects — mobile, wearable, or otherwise — and say goodbye to (some) batteries and plugging things […]
It’s now possible to build remote, low-power microcontroller projects that can operate indefinitely without batteries and still not crash, even if power is interrupted.
Working with “wireless” LEDs feels a bit like magic. These tiny LED assemblies can emit light without directly connecting to a power supply.
On December 21st, 1968, exactly 55 years ago today, NASA sent humans outside of low earth orbit for the first time, captivating the world and ushering in a new era of space travel.
Textile printing — the application of colored patterns to fabric — is not a new phenomenon. Woodblock-printed fabric dates back hundreds, perhaps thousands of years, and has been widely available in forms such as chintz and calico since before the Industrial Revolution.
In the early 1950s, aircraft development created an urgent need for simulations, and analog computers were ideally suited to run flight simulators.
