Tutorial: 1/2 Watt Guitar Amp

amp and slide

"Little Gem" amp runs off a 9v battery and can be built with just a handful of small parts. It has a great natural distortion and works well as a practice amp for camping or traveling.

"The Doorman"

The Doorman is a Halloween animatronic made with 3d printing and Raspberry Pi

Cricut Alien

I built this motion activated fellow in between projects at work. I used gimp photo editor to design the pieces for the alien and his articulating arm, which I cut using a Cricut Maker.

utrasonic

This was fun quick project; the hardware required is just a raspberry pico, an ultrasonic distance sensor and two servo motors. The HC-SR04 Ultrasonic Range Sensor sends an ultrasonic signal several times each second. The signal bounces off of an object, reflecting back to the sensor. Using the duration of time between emission of the signal, to when the signal bounces back to the sensor, you can determine the distance between the sensor and an object. So when a coworker walks within a few feet of Cricut Bot, he'll greet them with a wave.

Trashkoloshe

In Xhosa and Zulu culture, the Tokoloshe is a small impish demon that can be summoned to cause mischief and misfortune.

Because we like spooky things in our family, and because I was eager to show off my raspberry pi skills, I decided to make each member of my family a 'Trashkoloshe'; a motion activated trash can that played from a random list of catch phrases each time someone threw something away.
