Rate Gyroscope circuitry explained

rate-gyroscope-driver

Hackaday alum [Adam Munich] shot a tutorial video on using a rate gyroscope.

Here he’s showing off the really fancy piece of ancient (technologically speaking) hardware. It would have set you back about fifteen grand in the 1960′s (inflation adjusted) but can be had these days for around $30. What a deal! These are not small, or power efficient … Read the rest

Quadcopter brain

quadcopter-brain

This project is the warm center of [Alan Kharsansky's] thesis in Electronic Engineering. It’s an all-in-one control board for a quadcopter. This is the second iteration of the board, the first version he actually etched himself. As you can see after the break the firmware is not quite ready for prime-time. But that doesn’t stop us from appreciating the … Read the rest

Pinoccio Web Rover

web-rover

Before assuming that the title should be “web crawler,” just shush your shussins’ and check out the video after the break. The Pinoccio, as previously noted, is a board in development as a sort of web-enabled by default Arduino. This makes it perfect for a project like this one where a little rover is controlled from 10,000 Kilometers awayRead the rest

Music challenge has you flapping your wrist to make sounds

glove-based-music-challenge

This glove controller let you play a musical game. The challenge is to perform the correct wrist motions at the right tempo to play the intro to the song Where is my Mind by the Pixies. This is demonstrated in the video clip after the break.

We often see flex sensors used on the fingers of glove projects, but … Read the rest

Heat-seeking firebot drowns out the flames

This robot can find and extinguish fires automatically. It is the culmination of an Embedded Design class project from last school year. [Dan] and his classmates developed a turret that holds both a spray nozzle and heat sensor which would be a fantastic building block for a real-life tower defense game.

The jewel of the sensor array is a TPA81 … Read the rest

LED cyber eyes; more nerdy than just taping your glasses

Regular glasses are okay, but these light up and respond to your movement. [Dr. Iguana] is at it again, designing a very interestingly shaped PCB to augment your visual augmentation devices.

The circuit board has two thin curving wings which conform to the shape of a pair of glasses. In the middle there’s a larger area that holds most … Read the rest

Fantastic programming makes this Arduino gaming device something special

The hardware that went into this Arduino gaming console is just fine. But the coding that produced this game called Twisted SNAKE is beyond compare. [Rodot] has programmed several games for the hardware, which uses an Arduino, 160×168 TFT screen, a 3 axis accelerometer, and two input buttons. If you’re interested, there is a forum thread in which he … Read the rest
