The photo above beautifully combines two things I really like a lot: Raspberry Pi and cake. To celebrate the Raspberry Pi’s first birthday, our friends at Element-14 presented an enormous Raspberry Pi-shaped cake to Pete Lomas from the Raspberry Pi Foundation and Andrew Robinson, the creator of the PiFace. Element-14, one of the official distributors […]
When I first started prototyping electronics projects with the Raspberry Pi, I noticed that I was wasting a lot of time looking at the GPIO pin chart and counting pins on the board when I wanted to connect a jumper to a particular pin. It made me realize that I take for granted the boards […]
Kevin Osborn was tired of worrying about getting dust from his ShapeOko CNC mill into his computer. Using a Raspberry Pi and an AlaMode shield he can now send G-Code to the machine over his wireless network, leaving his computer clean and available for other tasks. According to Kevin, “this is of the simplest and most rewarding applications of AlaMode.”
I’ll admit it: I’m an enclosure geek. From the sleek, brushed-metal case I got for my first Mini-ITX computer, to the sheet steel box I wrapped around the electronics in my Nerf Sentry Gun build, I put a lot of thought into selecting the right case for the job. For my new Raspberry Pi Model B computer, however, I didn’t have to think very long. Not after I first laid eyes on the Barch Designs Raspberry PiHolder.
Without an external digital to analog converter circuit, getting pulse width modulation out of more than a single PWM pin on the Raspberry Pi could be achieved by writing your own code to set the pins high and low at the appropriate time (i.e. bitbanging). The solution isn’t perfect, however. Since you’re sharing the CPU […]
When Shawn Wallace and I wrote Getting Started with Raspberry Pi, we wanted to include a few projects that demonstrated the strengths of the single-board computer. One of those strengths is the ability to run a fully-fledged dynamic web server that could take direct control of the GPIO pins for turning on and off household […]
Right now there are two new micro-controller boards seeking funding—one on Kickstarter, and the other on Dragon Innovation’s new crowdfunding platform—that are slightly different. These boards aren’t just yet another Arduino clone, or yet another possible “Raspberry Pi killer.” These two boards, the Tessel from technical.io and the Espruino from Pur3, intend to take the path least travelled and co-op an existing community not traditionally associated with the maker community.
