When in Rome, most people visit great works of art, see masterpieces of architecture, or simply try to convince random tourists that a modern recreation of naval battles in the Colosseum would be really cool and somebody should really get on that. [Andrew] had a different idea, though. He thought meeting up with Slic3r developer [Alessandro Ranellucci] [...]

[Andrew] has enjoyed the company of [Pepper] the parrot for more than a decade, but the screeching of a bird in the next room is something you just don’t get used to. [Pepper] gets very lonely some times, and short of having someone carry him around on a shoulder, there’s not much that will calm [...]

[Andrew Gibiansky] has just started a tutorial series called Computing with Transistors. It’s purpose is to pull back the many veiled layers between high level languages and the controlling of electrons. And fittingly this first post starts off by explaining voltage source, load, and current. Don’t be thrown by its simplicity though. [Andrew] quickly moves [...]

[Andrew] picked up a handful of these big STC 8051 chips for a song and dance. The problem he has with them is the clunky VB6 programming software that only wants to run on a Windows box. He buckled down and wrote his own programming software called stcdude. As you have probably guessed, it’s meant [...]

At the center of that green PCB is a tiny little processor with way too many cores. It’s the GA144 which was taken for a test-drive on a breadboard by [Andrew Back]. We saw a multi-core Kickstarter project last month. This will cost a lot less and get you more than twice the number of [...]

[Andrew] has been pining for an Optimus Maximus – a keyboard with a small LCD screen in each key – for years. Like a lot of people, he love the idea of a completely configurable keyboard, but balked at the two thousand dollar price tag. Although it doesn’t have full color OLED screens behind each key, [...]

[Andrew] recently got the authorization to install Linux on his work PC, and he was looking for a way to control his music without relying on keyboard shortcuts to do so. Additionally, he wanted an unmistakable visual cue when he received messages in Pidgin, so he decided to build an external input/notification box. The control [...]

[Andrew] and his brother had some time (and a lot of ping pong balls) on their hands, so they decided to have some fun and built a remote-controlled ping pong ball turret. Arduino aside, the turret is cheap and easy to build as [Andrew’s] writeup explains. The firing mechanism was constructed using a pair of [...]

[Andrew Robinson] and his co-workers are lucky enough to have a Keurig coffee maker in their office, though they have a hard time keeping track of who owes what to the community coffee fund. Since K-Cups are more expensive than bulk coffee, [Andrew] decided that they needed a better way to log everyone’s drinking habits [...]

[Andrew] is trying to buckle down and hammer out his PhD project but was surprised by the sorry state of the configuration options for his FPGA/ARM dev board. Using JTAG was painfully slow, so he studied the datasheet to see if there was another way. It turns out the Xilinx FPGA he’s using does have [...]

[Andrew] has an ASUS wl520-gU router that he is pretty fond of, despite its numerous problems. CPU clock bug aside, the router only has 16MB or memory like many others on the market. While tooling around with the bootloader he bricked the device, so he decided it was time for an overhaul. After some searching [...]

The best laid plans of mice and men oft go awry. At least that’s what we’d tell ourselves if we couldn’t find a 30-year-old computer monitor. [Andrew] picked up an old IBM XT on eBay recently and tried to get the video working. He hasn’t seen any success yet, but the way he goes about [...]

GPS receivers may be available for well under $100 these days, but what’s the fun in buying one when you can build it yourself? According to [Andrew], the creator of this device, he was inspired by Matjaž Vidmar who developed a GPS receiver from scratch over 20 years ago. His article can be found here [...]

For his A-level electronic course work, [Andrew] decided to build a digital sound recorder that doesn’t use a microcontroller. [Andrew]‘s build captures audio from an on board microphone at 8000 samples/second. The audio is digitized into 8-bit sound data and sent to an SRAM. The recording and playback functions are controlled entirely by 4000-series logic chips. He [...]

[Andrew] recently ordered some lockets to bejewel them with some LEDs but got a bonus small locket for free with the order. Not really having a plan for the small locket it kind of sat around until finally some inspiration hit. Meet the ee-locket which contains a tiny circular pcb with a 64k eeprom, a [...]

As an amateur radio enthusiast, [Andrew] sometimes has to set up impromptu antennas up to 160 meters in length. The easiest way to get these antennas off the ground is to drape them over trees, a feat normally accomplished by lofting fishing line into the air with a slingshot or bow and arrow. [Andrew] thought [...]

Sometimes it’s apparent that there is no practical use for something featured on Hack a Day, but we don’t know if [Andrew Filer]‘s Apple ][ USB keyboard qualifies for this. After reading through the very thorough documentation available in electronic and dead tree formats, [Andrew] decided that Apple ][ would make a great USB keyboard. [...]

Brushless motors and the way in which they are controlled can be a bit of an enigma to those just starting out in hobby electronics. [Andrew] from spingarage thought it would be helpful to put together a quick tutorial showing how he built a simple brushless motor controller in about a day’s time. He constructs [...]

Long before drum machines played samples from an SD card or EPROM, drum sounds were analog – just filtered waveforms and noise. To the modern eye, these are very primitive machines, but for [Andrew], they’re the inspiration for this brilliant hack. [Andrew] took a Roland CR-68 drum machine from 1978 and added MIDI input with the [...]

While the Sega Dreamcast has long been out of production, there is an avid fanbase that loves the console dearly. As with many CD/DVD-based consoles, the Dreamcast can sometimes run into issues reading discs, at which point all games are unplayable.

[Andrew] recently offered to help out a friend who was looking to get her husband a SNES controller belt buckle. Rather than simply slap one together, he decided that it would be far cooler if the belt buckle played audio as well. He gutted a broken SNES controller, removing most everything inside, leaving just the [...]

[Andrew] built himself a stoplight that flashes along with the music. Unlike the traffic signal we checked in on a year ago, this one’s not a reused municipal fixture. [Andrew] imported a 3D model into Sketchup, printed out the results, and traced them onto Bristol board to make his templates. He cut out the parts, [...]

One complaint we hear about often is ear-bud’s cables getting tangled within backpacks. [Andrew] was having this “spaghetti” wire problem, and also wanted to listen to his music with ear protection on – where ear-buds are usually uncomfortable. The latter problem is fixed by placing speakers inside of folding ear protectors, and the cable is [...]
