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, 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

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
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

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
As you may know, we’re rather big fans of building things here at Hackaday. But we’re also quite partial to repairing things which might otherwise end up in a landfill. Especially when those things happen to be interesting pieces of vintage hardware. So the work [ekriirke] put in to get …read more
Figuring out the maximum number of peripherals which can be sensed or controlled with a minimum number of IOs is a classic optimization trap with a lot of viable solutions. The easiest might be something like an i2c IO expander, which would give you N outputs for 4 wires (SDA, …read more

The RetroPie project is a software suite for the Raspberry Pi that allows the user to easily play classic video games through emulators. It’s been around for a while now, so it’s relatively trivial to get this set up with a basic controller and video output. That means that the race is on for novel ways of implementing a RetroPie, which [Christian] has taken as a sort of challenge, building the tiniest RetroPie he possibly could.
The constraints he set for himself were to get the project in at under 100 mm. For that he used a Pi Zero loaded …read more
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

Head-mounted displays range from cumbersome to glass-hole-ish. Smart watches have their niche, but they still take your eyes away from whatever you are doing, like driving. Voice assistants can read to you, but they require a speaker that everyone else in the car has to listen to, or a headset that blocks out important sound. Ignoring incoming messages is out of the question so the answer may be to use a different sense than vision. A joint project between Facebook Inc. and the Massachusetts Institute of Technology have a solution which uses the somatosensory reception of your forearm.
A similar …read more
