Sony’s SmartWatch is an Android compatible watch based on an ARM Cortex-M3 CPU, STM32F205RGY6, from STMicroelectronics and includes Bluetooth capability and a touchscreen. It retails for around $100. Previously, developers could create apps for SmartWatch with the Sony Add-on SDK, but Sony is now opening up the project to allow hackers to create and flash […]

Controlling six 17-segment digits using three I/O pins

Wardy posted this article:  Controlling six 17-segment digits using three I/O pins Decided to start making good use of my “Propeller Professional Development Board” (PPDB) which has been sitting sadly idle and forlorn on the bench for a while. Set a goal of making a simple video game with some of the advanced features available […]

Spindicator clone with pulse and trail effect

In this video Viktor demonstrates his Spindicator clone with pulse and trail effect project: Although my “original” Spindicator itself was just a clone of this one, mine was well received by the geeks around the world! :) A fellow diy tinkerer made an even better one with PWM control (very cool, indeed!). Recently, I was asked […]

Reusing old Java ME devices in hacking projects

In this video from the Oracle Learning Library, Vinicius Senger and Marcelo Quinta demonstrate how to repurpose old Java ME mobile devices in hardware hacking projects. This talk, which was originally presented at last October’s Oracle Open World conference in San Francisco, concentrates on different ways to use Java ME for educational purposes, as well […]

Karma controller project

William built this Karma controller and wrote a detailed explanation on his blog describing the build: My latest project is the Karma Controller, which has seven buttons to control Reddit Enhancement Suite. I made two revisions. The second is custom etched (which looks super cool!). I’ll also be sending them off to a real PCB shop for […]

Wireless voice-controllable smart home project

Wireless voice-controllable smart home project by Jiayuan Wang and Sheng Zhang from Cornell University, built as a final project: There are two CPU in our project, ATmega328 and ATmega1284. We set up the wireless communication by two Xbee chips. One of them connects with ATmega328 working as the transmitter to transmit the signal, another one […]

MIDI OUT for vintage Korg CX-3

Michael from AcidBourbon writes, “This project is about adding a MIDI output to a vintage organ, the Korg CX-3 (famous Hammond compact organ clone). My Korg was built in 1979, so before the introduction of the General Midi standard. But tapping into the right (only three) conducting paths on the main PCB and using a […]

Stepper motor bluetooth serial driver (Attiny85 & L293D)

Trandi blogged about his Stepper motor bluetooth serial driver project: How to put together a simple bluetooth driver for a nice little stepper motor (Mitsumi M35SP-11HPK) that I salvaged from an old Canon printer. It uses a small Attiny85 (the more I use them the more I love them ! :) ) programmed in Arduino, […]

Chipper – ATtiny programming and prototyping shield

Here’s an interesting project the Chipper – ATtiny Programming and Prototyping Shield built by Ben Rothschild: As a high school senior and electronic enthusiast, I recently built a programming shield for 10 different types of ATtiny chips that can be used with either an AVR programmer or Arduino Board. Some of the features on the […]

Arduino guitar mod lets you type with a tune

David Neevel of W&K Blog had been thinking about modding a guitar to use as a keyboard for some time. As shown in this video, he recently got down to business, interfacing the MIDI output through an optoisolator circuit to the Arduino. The interpretation of notes to keyboard characters is accomplished in code, with the […]
