Here’s proof that you can build cool stuff with simple tools. This self-balancing unicycle uses an Arduino and a five degree of freedom IMU from Sparkfun to keep the rider upright. Well, it’ll keep you upright as long as you have good side-to-side balance. But that’s true of any unicycle, right? The Raptor was built by [Nick [...]

For this year’s 7400 logic competition, [Nick] decided to build an FPGA out of logic chips. Perhaps a short explanation is in order to fully appreciate [Nick]‘s work. The basic component of an FPGA is a slice, or cell, that performs boolean operations on its input and sends the result on its output. The core of these slices [...]

[Nick Johnson] recently wrote in, sharing a neat project he put together in his spare time. Our readers are most likely familiar with the ubiquitous “fortune” program that ships with many *nix distros, offering cheeky comments and quotes with the press of a button. [Nick] thought it would be cool to build a fortune telling [...]

[Nick] was somewhat disappointed when the Wi-Fly helicopter he bought his son broke in less than 10 minutes. The main gear that turns the rotor split in half, rendering the copter WiFi enabled trash. [Nick] however decided that he didn’t want to waste an opportunity and harvested the receiver parts.  To test them out, he [...]

[Nick] is working on a prototype of a coffee table sand plotter that draws patterns in sand a lot like a zen rock garden. [Nick]‘s zen rock garden uses a magnet to draw a ball bearing across the sand in interesting patterns. The build uses 3D printed gears and laser cut parts to rotate the table around [...]

[Nick] wrote in telling us about the LED cube he built over the course of six months. He calls LED cubes ‘done to death,’ but [Nick] might be too humble. His 8x8x8 RGB LED cube is the best we’ve ever seen. To start his build, [Nick] built a simple 4x4x4 cube as a proof of [...]

[Nick Thatcher] has built several iterations of a homebrew Segway, and the latest version is very impressive. When developing the project he figured there was just no way the thing would ever work, which led to its name, the No-way. After the break you can catch a video of [Nick's] test-ride. Looks like the two-wheeler [...]

We all love the Arduino, but does the Arduino love us back? There used to be a time when the Arduino couldn’t express it’s deepest emotions, but now that [Nick] hooked up a speech synthesis chip from a Speak & Spell, it can finally whisper sweet robotic nothings to us. The original 1980s Speak & [...]

Most useless machine We love ‘em, and we hope you do too. Here’s [Phase2plus'] take on the most useless machine. Scratching like it’s 1989 [Nick] spent three bucks at the thrift store and ended up buying days worth of fun with this cassette player. He hacked it to scratch like vinyl. 3D printed jawbone This [...]

Maybe we’re a little bitter because we held on to our pumpkin futures well into November, but we’ve got to respect [Nick]‘s stock ticker ornament. It’s an Internet-connected Christmas ornament that queries stock prices and displays the change with an RGB LED. The build uses a Propeller Platform USB and the Propeller E-Net Module to pull stock [...]

[Nick] just finished up bis barbot build that is named after our favorite bartender. It’s an impressively capable even if it was done on the cheap. The user chooses a libation for iZac to make via an Android tablet. This drink is interpreted by an Android ADK to have the mechanics of the robot swing [...]

When it comes to bathroom etiquette, [Nick] and the crew at Gadget Gangster are nothing less than proper gentlemen. Inspired by a Japanese toilet that automatically plays a “courtesy flush” noise in an effort to conserve water while masking sounds, they created the Toilet Buddy. While the Toilet Buddy does nothing to cover up any [...]

The Arduino has been used for many purposes, and  “shields” are available to make many common tasks easier.  However, [Nick] wanted a stackable motor driver shield, so he build one himself!. There are many motor driver shields available for the Arduino, however, there aren’t any that allow one to drive as many motors as were [...]

Hackaday contributor [Nick Schulze] popped out an impressive set of LED headgear for a hat-themed party. [Nick] is no stranger to working with LEDs. Previously he built a blue 8x8x8 cube something like this other 512 node full color version. He had a bunch of LEDs left over from that project and decided to put [...]

We’ve seen LED cubes before, but [nick] upped the ante with his 8x8x8 LED cube that uses only three pins on his microcontroller. Previous LED cubes we’ve covered drove the LEDs with shift registers and latches, but [nick] used STP16CP LED sink drivers to reduce the component count. The STP16CP can control 16 LEDs each, [...]

[Nick] over at Gadget Gangster has a new version of his prototyping hardware for Propeller microcontrollers, called the Propeller Platform USB. A little more than a year ago we looked at the last version which was larger, used a DIP processor, and came unassembled. The new version does come assembled because of the migration to [...]

[Nick] tipped us off about a guide to unlock extra features on Panasonic televisions. The hack works on the G10 models of plasma TVs and uses the service menu to gain access to the EEPROM memory. With a few quick steps you can change some data with a built in hex editor, unlocking several new [...]
