Raspberry Pi Helps Vintage Psion Find its Voice

Ask a hacker to imagine computing in the 1980s, and they might think of the classic 8-bit all-in-one machines from the likes of Commodore and Atari, or perhaps the early PCs and Macs. No matter the flavor, they’ll likely have one thing in common: a lack of mobility thanks to …read more

3D Printed Snap Gun for Automatic Lock Picking

At a far flung, wind blown, outpost of Hackaday, we were watching a spy film with a bottle of suitably cheap Russian vodka when suddenly a blonde triple agent presented a fascinating looking gadget to a lock and proceeded to unpick it automatically. We all know very well that we …read more

E-Book Reader Gets Page Turn Buttons, Is None The Wiser

Most e-book readers don’t have physical page turn buttons. Why? They just don’t. Virtual page turns are accomplished with a tap at a screen edge. Determined to reduce the awkwardness of one-handed use, [Sagar Vaze] modified a Kobo e-reader with two physical page turn buttons as a weekend project.

[Sagar] …read more

The ArduBoy Community Rolled Their Own Cartridge

The ArduBoy, as you might have guessed from the name, was designed as a love letter to the Nintendo Game Boy that many a hacker spent their formative years squinting at. While the open source handheld is far smaller than the classic DMG-01, it retains the same general form factor, …read more

One Arduino Handheld to Rule Them All

There’s nothing quite as annoying as duplicated effort. Having to jump through the same hoops over and over again is a perfect way to burn yourself out, and might even keep you from tackling the project that’s been floating around in the back of your mind. [Alain Mauer] found that …read more

Building An ESP8266 Game System With MicroPython

After a seemingly endless stream of projects that see the ESP8266 open doors or report the current temperature, it can be easy to forget just how powerful the little WiFi-enabled microcontroller really is. In fact, you could argue that most hackers aren’t even scratching the surface of what the hardware …read more

A Keyboard For Your Thumb

Here’s an interesting problem that no one has cracked. There are no small keyboards that are completely configurable. Yes, you have some Blackberry keyboards connected to an Arduino, but you’re stuck with the key layout. You could get one of those Xbox controller chat pads, but again, you’re stuck with …read more

A Practical Portable Wii Emerges from the Memes

A few months ago, [Shank] built what will almost certainly go down in history as the world’s smallest portable Nintendo Wii. As it turns out, the Wii motherboard is home to a lot of unnecessary hardware, and with a careful hand and an eye for detail, it’s possible to physically cut it down to a much smaller unit; allowing this particularly tenacious hacker to put an actual Wii, along with everything else required to make it portable, into an Altoids tin.

As you might expect, between the cramped controls, comically short battery life, and the fact that the whole thing …read more

Classroom Gadget Turned Arduino Compatible

Cheap second-hand hardware is usually a fertile ground for hacking, and by looks of this project, the digital classroom aids that were all the rage a few years back are no exception. [is0-mick] writes in to tell us how he managed to hack one of these devices, a Smart Reponse XE, into an Arduboy compatible game system. As it turns out, this particular gadget is powered by an ATmega128RFA, which is essentially an Arduino-compatible AVR microcontroller with a 2.4GHz RF transceiver tacked on. This makes it an extremely interesting platform for hacking, especially since they are going for as little …read more

Sonar in Your Hand

Sonar measures distance by emitting a sound and clocking how long it takes the sound to travel. This works in any medium capable of transmitting sound such as water, air, or in the case of FingerPing, flesh and bone. FingerPing is a project at Georgia Tech headed by [Cheng Zhang] which measures hand position by sending soundwaves through the thumb and measuring the time on four different receivers. These readings tell which bones the sound travels through and allow the device to figure out where the thumb is touching. Hand positions like this include American Sign Language one through ten. …read more
