New in the Maker Shed: Ephrem’s Deluxe Bottle Cutter

We’ve featured Ephrem’s Bottle Cutter in MAKE:Vol 28, Matt Richardson’s Video (shown below) and in Make:Projects, so it’s about time we made it available in the Maker Shed! This deluxe kit includes the bottle cutting jig, carbide polishing compound, a candle, instructions, and a special adapter to allow cutting on the neck of the bottle. Perfect making everything from drinking vessels to bottleneck guitar slides.

Laser Ball Is Life of the Party, Makes Regular Tennis Balls Feel Inferior

Laser Ball Is Life of the Party, Makes Regular Tennis Balls Feel Inferior

LeoneLabs on Instructables posted this fantastic how-to on adding 14 lasers to a regular tennis ball to make a Laser Ball. Why? He says that it’s fun to build, it can be done in an afternoon, and “lasers are cool.” The lasers are driven by a Teensy USB Development Board, which is stuffed inside the ball and controlled from outside with an infrared remote control. The Instructable shows you how to make your own in painstaking detail, but you can also follow the build step-by-step in this fun video.
