Hack a Day
[Andrew Holme] wrote in to tell us about some work he’s done to improve his scratch-built GPS receiver. He figured out a way to use the same hardware but double the number of satellites it can track to a total of eight. When we looked at the original hardware about a year ago it was [...]

What does a hacker do when going into battle for the freedom of their country? He builds a tank from scratch, of course. It’s a little bit of a stretch calling it a tank as it lacks treads. But it’s got a high-caliber gun mounted on top and has been heavily armored. There is room enough [...]

[Rob] lives in a 100-year-old house, and with these antique lath and plaster walls and old window frames comes a terrible amount of drafts. The usual way to combat this energy inefficiency is with a thermal imaging camera, a device that overlays the temperature of an object with a video image. These cameras are hideously [...]

This Portal gun will really make [aNoodleJMC's] costume pop this year. He actually built the video game weapon replica from scratch. It even includes some electronics to light it up blue or orange depending on which portal he’s planning to fire at an available flat surface. There’s a lot of parts that went into the project, [...]

Extremely powerful ARM microcontrollers have been around for ages now, but only recently have they been available for just a few dollars with a good enough toolchain for some serious development work. [Jose] wanted to develop something awesome with an ARM chip he had lying around, so he built a PDA (Spanish, translation) that can be used [...]

CD and DVD payers can often keep the music or movie going despite a small scratch. But occasionally you’ll have to skip to the next chapter/track or the player will just give up. But with data back-ups, a scratch can bork a whole set of files. We think that most of the time these headaches can be [...]

[Kevin Osborn] is making it a bit easier for young programmers to write programs that interact with the physical world. The device he’s holding in the picture is an Arduino based accelerometer and distance sensor meant for the Scratch language. Scratch is a programming language developed at MIT. It has kids in mind, and focuses on [...]

We know that most of you will have no reason to ever make a miniature X-ray tube. However, we also know that many of you will find this video mesmerizing like we did. [Glasslinger] does a fantastic job of explaining the entire process of creating the mini x-ray tube from, procuring the uranium glass and [...]

[Radek] from Poland sent in a neat video of a bionic prosthetic leg he made for one of his patients. Even though [Radek] says it’s a ‘prototype of a prototype,’ we’d have to agree with him that it’s a very neat build that could provide inexpensive motorized prosthetic legs to amputees in the future. [Radek] has been [...]

After over a year of work, [dmw] is nearly done with his Humble Hacker Keyboard. It’s a keyboard that has been influenced by some pretty crazy looking designs, but meets all of [dmw]‘s needs for a compact, programmer-oriented key layout that’s easy to type on. [dmw] posted a pseudo-build log over at the geekhack keyboard forums. [...]

Sure, [Stan] could have bought a nice full-frame DSLR like a Canon 5D or a Nikon D3, but where’s the fun in that when he could build his own digital camera? The build isn’t done yet, but [Stan] did manage to take a few sample pics. The 14 Megapixel sensor [Stan] found was originally used [...]

If you’re looking to build a really big Android tablet the trick is not to start from scratch. [Peter] pulled off a 23″ Android Tablet hack using a collection of easily acquired parts, leaving the hard work up to hardware that was designed to do it. He didn’t really build a tablet, as much as [...]

We had some interesting High Voltage posts over the past couple of weeks. Today we are announcing the next theme: Engine Hacks. Each day for the next two weeks we will be doing a new post about some sort of interesting engine project. We’ll be showing projects where engines are built from scratch, engines are [...]

[Rhys] wrote in to share a custom project box he built from scratch using polyester resin. He states that in New Zealand, he tends to have problems finding the perfect project box. They are typically too big or small to get the job done, so he figured he might as well just build his own [...]

It took us a while to stop drooling long enough to write about this amazing machining project. [Denis MO] made a single-lens reflex camera from scratch. The banner image above is not the finished product, but just one step in the production chain. [Denis] has been thinking about doing this project for 25 years and [...]

[Kenneth] built this scoreboard for use at a ballpark that lacks such luxuries. We think this a phenomenal application for his skill and his pocketbook. He laid out PCBs for each digit in Eagle and etched them himself, then installed the indicators for home score, visitor score, inning, balls, strikes, and outs in a laser cut case. [...]

There’s something viscerally pleasing about simple solutions. [Kip] came up with one in the form of a scratch controller. The spindle from an optical drive is used to hold a CD in place, which acts as the LP for scratching. The sensor from an optical mouse is mounted upside down below the CD and detects [...]
