Hack a Day
[Michael] wanted a stereo that he could use outside, be it at the beach, beside the pool, or while tailgating. He decided to build this boom box himself, and didn’t cut any corners when it came to a professional looking finish. Because of the locale in which he plans to use the stereo he went [...]

[Michael], [Tom], and a few other people on the Lucid Scribe Database project have been using off-the-shelf EEG equipment to invoke lucid dreaming. Yes, that’s where you take control of your dreams and become a god. This requires wearing an EEG setup while you sleep, and these products aren’t very comfortable sleeping wear. [Tom] decided to take [...]

We’ve tried building our own ARM cross compiler on a Linux box and it’s no picnic. Luckily there is a free cross compiling toolchain available through Mentor Graphics (formerly called Code Sourcery G++). But those looking to develop on a Mac aren’t so lucky. There is help via a script, and [Michael] wrote a guide [...]

The great thing about building with gates is the crazy speeds you can achieve by using hardware directly (as opposed to working with simple microcontrollers). This 100 MHz frequency counter is a great example. [Michael] just finished building it using a Papilio board. Of course we’re not talking about discreet chips here. The Papilio is [...]

Over the last few years, [Michael] has been developing a PIC microcontroller board. He calls his project USBPIC, and with the addition of a few FET drivers, H-bridges, and LED drivers his homemade dev board can handle just about anything thrown at it. [Michael]‘s board is build around a PIC18F2455 microcontroller with both an In Circuit [...]

[Michael] built his own clone of the popular MaKey MaKey Kickstarter project. His implementation uses an ATMega328 and the V-USB stack to connect as a USB Human Interface Device. He was showing it off at Toorcamp wired up to a banana piano, which captured the interest of kids and adults alike. The digital inputs are [...]

[Michael H] tipped us off about this guide to using view camera lens parts with DSLR cameras and lenses. We weren’t familiar with the term ‘view camera’ but we certainly recognize the accordion-like bellows that define that type of camera. The idea is that modern cameras with their fixed lenses miss out on some types [...]

Hack a Day
The newly released Arduino Leonardo has a few very interesting features, most notably the ability to act as a USB keyboard and mouse thanks to the new ATmega 32U4 microcontroller. This feature isn’t exclusive to the Leonoardo, as [Michael] explains in a build he sent in – the lowly Arduino Uno can also serve as a [...]

Hack a Day
Over the last few years, [Michael] has been working on the Lucid Scribe project, an online sleep research database to document lucid dreams. This project uses a combination of hardware and software to record rapid eye movements while sleeping. Not only is [Michael] able to get his computer to play music when he starts dreaming (thus [...]

[Michael] sent in a question regarding the latest advances in software defined radios available for $20 on eBay: I’ve been looking in to SDR lately, mainly for the possibility of using it for incredibly cheap radio astronomy. So far all I’ve found are whispers. I’m 18 and have very little experience, but I figured you [...]

Some of the very largest – and coolest – CNC machines use supported linear rail for their movement axes. For any home tinkerer trying to reproduce these supported rails, the problem of cost comes up very quick; these rails can run over $100 for just a few feet. [Michael] came up with a great way [...]

The more we think about this one the more we like it. [Michael] built himself a wind-powered persistence-of-vision weather station. Okay, that sounds interesting, but he ups the ante when you find out what’s included in the system. A stepper motor acts as the generator which powers the electronics. As we’ve seen before; if you spin [...]

Hack a Day
The Syma S107 IR is a popular little remote controlled helicopter. When a friend of [Michael]‘s started flying one around the office he decided to try and jam the signal, creating a no fly zone. Luckily some people on the internet have already decoded the IR signals used by the flying menace. From there, a [...]

Hack a Day
Even though everyone with a smart phone has a small, powerful computer in their pocket, we haven’t seen many applications of this portable processing power that use the built-in camera. [Michael] decided to change this and built an LED matrix that displays the data coming from the phone’s camera. For the build, [Michael] used two [...]

Hack a Day
[Michael] is a huge fan of old media formats. There’s something special about quarter-inch thick 78s, fragile blue cylinders holding music, and thin strips of mylar that preserve the human voice. He’s had an idea for a tape-based instrument for a while, and now that the Magnetotron is complete, we’re in awe of this glass harmonica and [...]

When it comes to Halloween costumes, [Michael] doesn’t like buying expensive and poorly made bits of cloth and fabric that resembles [random Disney character]. Last year, his son decided to be a robot for Halloween and although gray spray paint and dryer vent hose make a very good costume, that only goes so far. The [...]

Hackaday reader [Michael] wrote in to share the build details of an impressive lighting console he has been working on for some time. He says that the 36+ channel console is on par with lighting rigs costing upwards of $5,000, but his was constructed for just around $1,000 – quite the substantial savings. The console [...]

[Michael] from Nootropic Design wrote in to share an interesting and fun project he put together using one of the products his company sells. The gadget in question is their “Video Experimenter” shield which was designed for the Arduino. It is typically used to allow the manipulation of composite video streams via overlays and the [...]

Hack a Day
We see lots of persistence of vision projects around here, but we can’t recall any that involve a POV display facilitated by a living, breathing animal (humans aside, if you want to picky). [Michael] has a Miniature Pinscher that just loves to run and run…and run…in circles. Since she generally runs very fast and in [...]

Hack a Day
We know you just got a links post a couple hours ago, but more people tipped us off to some great Halloween stuff and we just couldn’t wait. [Michael] came up with this fantastic idea for a flying ghost. He’s using a twin prop tilt rotor design to fly his ghost all over the neighborhood. [...]

Hack a Day
[Michael] designed this display board to mimic the appearance of a police car pulling you over. It resides in the rear window of his car (facing forward) as the controller board measures the speed of the vehicle. An Arduino grabs NMEA data from a GPS module and compares it with a table of speed limits. [...]

[Michael] sent us a link to his RC robotic platform. He started with the same RC toy as the iPhone Robot (CAR) but ended up with a blank slate waiting for more features. What he has is an Arduino with a motor driver, three bump switches for the front and rear, and a XBee module. [...]
