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.
With the proliferation of single-board computers and the various flavors that they come in, it can be a bit daunting to a newcomer. Added to the vast array of programmable microcontrollers like the Arduino, it only makes platform decisions that much more complicated. In fact, we are frequently asked about the difference between the Raspberry […]
With all the microcontrollers and single board computers on the market, sometimes it’s hard to see all your options. That’s why we made up this quick reference sheet for the 8 most popular boards we sell in the Maker Shed.
Jason Birch built a hand held MAME device using a Raspberry Pi connected to a 3.5″ LCD screen. The unit is powered from a battery pack and runs for around 2.5 hours.
This Wednesday, Shawn Wallace and I will be hosting an O’Reilly webcast about the basics of how to get a Raspberry Pi up and running. It’s a free webcast, but you do have to register to attend. If you can’t make it to the webcast, check out our book, Getting Started with Raspberry Pi, which […]
