Creating a Dr. Who Handles replica



John F. has created a slick replica of Handles from Doctor Who that was recently featured on the official Adafruit blog.

The build uses an Atmel-based Arduino Uno (ATmega328 MCU), Wave Shield, Proto-Screw shield, triple axis accelerometer and a class D stereo amplifier. All of the components were purchased directly from Adafruit.

In related news, YouTube user Jamison Go is constructing an impressive Mercury Hammer that Debonair Jayce of League of Legends would be proud of! The cosplay hammer even transforms into a Mercury Canon – complete with lighting effects and moving parts.

According to the official Adafruit blog, Go’s iteration of the Mercury Hammer is packed with an RGB LED to change the prop’s colors between yellow and cyan, a servo to power the wings on the sides, solenoid valve to activate the extending rods and an Atmel-based Arduino board.

Building a speaking ultrasonic distance sensor

A Maker by the name of Klaus recently built a “speaking distance sensor” to help him park his car.

According to the HackADay crew, the platform is built around an Atmel-based Arduino Uno (ATmega328), an HC-SR04 ultrasonic distance sensor and Adafruit’s Wave Shield.

“Originally, this parking/distance sensor used a small TFT to display the distance to an object, but after a few revisions, Klaus redesigned the device to speak the current distance, courtesy of an SD card and a soothing female voice,” explained HackADay’s Brian Benchoff.

“Right now, the voice is set up to speak the distance from an object to the sensor from 10 cm to 1 m in 5cm increments. This isn’t the limit of the sensor, though, and the device can be easily reconfigured to sense a distance up to four meters.”

Currently, the board lacks an on-board amplifier/speaker, although adding a small amplifier (courtesy of Adafruit) should be sufficiently loud to be heard inside the noisiest parking lots and out in the street.
