Hack a Day
While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus. [Louis] sent in a tutorial for getting hardware SPI on his Raspi, and even though it’s rather limited [...]

Back at the turn of the century, shoving MiniITX motherboards into just about everything was all the rage with the technologist crowd. [waterbury] had the idea of making a computer out of an SNES, but with the added ability of reading SNES cartridges. This idea had been floating around in [waterbury]‘s head for years now, [...]

To put on a live pyrotechnic show at a music festival, [Chris] built the FireHero 3. The result is remotely controlled flames shooting up to 100 feet in the air. The system is controlled by a Raspberry Pi and an Arduino. A server runs on the Pi and allows a remote computer to control the [...]

Over on the Parts People blog, [Nathan] created his own Raspberry Pi laptop. It’s got all the bells and whistles, including a keyboard, trackpad, battery, and even a 3D printed case. Of course [Nathan]‘s laptop contains a Raspi, but the other included parts are where this palmtop computer is turned into something useful. For powering [...]

With so many uses for a Raspberry Pi in a headless configuration – especially with the impending release of the Raspi Model A – we’re surprised it has taken so long for someone to send in a way to create a custom message of the day that is displayed whenever you SSH into everyone’s favorite Linux [...]

Along with the growing popularity of the Raspberry Pi, we’ve also seen a related uptick in MAME arcade cabinet builds. Putting this $35 computer in an arcade cabinet makes a lot of sense, but connecting it to one of the monitors found in old arcade cabinets is a bit of a pain. Luckily, [Celso] figured [...]

[Stephen] took the safe route when getting his Raspberry Pi to dim an AC light bulb. He didn’t roll his own outlet box with a mains-rated relay inside, going with a mechanical connection instead of electrical. By attaching a servo motor to the dimmer knob the RPi can adjust the light level without risk of electric shock. [...]

If you’re lacking useful equipment for your Raspberry Pi hacking adventure, such as an HDMI monitor or power supply, this handy write-up will show you how to continue your hacking. All you’ll need is a laptop, the Raspberry Pi itself, an SD card, and an Ethernet and micro-USB cable. As noted in the article, it’s [...]

[Liz] over at the Raspberry Pi foundation took a trip over to the manufacturing facility in Wales and found some of the very first Model A Raspi samples. They’re just samples, but this means we should be seeing a few Model A Raspberry Pis pop up on Element 14 sometime very soon. As the lower-cost [...]

Yet another operating system has been ported to the Raspberry Pi. No, it’s not Haiku, sadly, but it is something just as weird and interesting. This time it’s Plan 9 from Bell Labs, an 80′s era OS from the same company that brought you C and Unix. As a research operating system, Plan 9 has [...]

So the Raspberry Pi sometimes doesn’t have the juice needed to run power-hungry USB dongles. The most common issue is with WiFi adapters. The solution has long been to use a powered USB hub, but [Mike Worth] didn’t want to take up that much extra space. The solution he worked out injects power directly into [...]

The folks over at the Raspberry Pi Foundation often gets asked “does it run Minecraft?” Mojang, the team behind the block building game, has announced that they will be releasing Minecraft: Pi Edition. This port will be based off the Pocket Edition of the game, but with a revised set of features. So what does [...]

We’ve seen hundreds of builds tinker around with the GPIO pins on the Raspberry Pi. They’re great for bridging the gap between physical sensors and a virtual world, but there are a few more unused and ignored pins on the Raspberry Pi. The folks at the Raspberry Pi foundation are finally giving these unused pins a life of [...]

This polar graph draws some amazing shapes on a dry erase board. Part of that is due to the mounting brackets used for the two stepper motors and the stylus. But credit is also due for the code which takes velocity into account in order to plan for the next set of movements. The Go [...]

Since he’s got several Raspberry Pi boards on hand [Eric Erfanian] decided to see what he could pull off using the robust networking tools present in every Linux installation. His four-part series takes you from loading an image on the SD cards to building a mesh network from RPi boards and WiFi dongles. He didn’t include [...]

The processor in the Raspberry Pi – an ARM11 built by Broadcom – actually has a long and storied history. Much as how the Intel i7 in a top-of-the-line desktop can still run code written for the original IBM PC, the ARM chip in the Raspberry Pi is also based on decades-old technology. The first [...]

[Ben] needed a case for his Raspberry Pi. Instead of going the usual laser-cut plastic or 3D printed route, he took a path far more familiar to us here at Hackaday. His case is built out of aluminum found in his basement, providing a neat reuse for some old aluminum extrusion he had lying around. Part one of [...]

There is buzz all over the reddits and Element 14 discussion boards about an updated version of the Raspberry Pi that bumps the amount of RAM from 256 MB to 512 MB. This new update comes after the announcement of an upgraded version of the yet-to-be-released Raspi Model A (from 128 MB of RAM to [...]

For this month’s release of Adafruit’s Raspberry Pi Linux distribution, [Limor], et al. decided to build a web-based IDE for the Raspberry Pi. The Raspberry Pi WebIDE is a web server that runs on the Raspi. By connecting to your raspi in a web browser, you’re able to create your own Python programs that are [...]

What you see here is a Raspberry Pi shoehorned into a power strip. The idea is to leverage the power and low-cost of this board into a stealthy network observation device. It packs a similar punch as the Power Pwn but should cost at least $1100 less! The fact that when you plug your Ethernet [...]

Up next on the continual march of expansion boards for the Raspberry Pi is the Raspy Juice, a board designed to break out the GPIO pins on the Raspberry Pi into servo, serial, and other miscellaneous connections. The Raspy Juice features an ATMega168A microcontroller connected to the Raspberry Pi as an I2C slave device. Not only does [...]

Do you think you could travel for the entire summer and leave your laptop at home? [Gef] did just that. With the help of his Kindle he used a Raspberry Pi as his travel computer. This was an easy association to think up, since he planned to bring the Kindle along as his reading material [...]

[Zaion] grabbed an ATX power supply to source the 5V the Raspberry Pi needs to run. The common problem when it comes to RPi supplies is a shortfall in how much current a USB wall adapter can source. The ATX shouldn’t have this problem, but none-the-less he found that the USB ports were only reading [...]

Ever wonder how an aerospace engineer would build a telepresence rover? Well, if [algorythmic] can be used as our reference, he’d cram a Raspberry Pi AND an Arduino into an RC truck frame. The arduino is being used for motor control while the Raspberry pi is doing the communicating back and forth to the base. [...]

We’re not sure why this use didn’t immediately come to mind when we got our hands on a Raspberry Pi board, but the hardware is almost perfect as a PBX system. PBX, or Private Branch Exchange, is basically an in-house phone system. This guide which [Ward] put together shows you how to do some interesting [...]

The folks at Adafruit are busy as a bee working on bringing some of their really cool boards to the Raspberry Pi platform. Here’s a few that came in over the last few days: 16 servos is almost too many Servos require a PWM output but the Raspi only has hardware support for PWM on [...]
