Collaborate Disseminate
With the prevalence of libraries, it has never been easier to communicate with hundreds of different sensors, displays, and submodules. But what is really happening when you type SPI.begin() into …read more Continue reading Taking A Deep Dive into SPI
Embedded Linux devices are everywhere these days, and sooner or later, you’re going to want to poke around in one of them. But how? That’s where posts like this one …read more Continue reading Camera Hack Peels Back Layers of Embedded Linux
Although protocols like I2C and SPI are great for communicating between embedded devices and their peripherals, it can be a pain to interface these low-level digital interfaces to a PC. …read more Continue reading Bridging the PC and Embedded Worlds with Pico and Python
Traditionally, a forum full of technical users trying integrate their own hardware into a game system for the purposes of gaining unfettered access to its entire software library was the kind of thing that would keep engineers at Sony and …read more

The basic test instrument suite — a bench power supply, a good multimeter and perhaps an oscilloscope — is extremely flexible, but not exactly “plug and play” when it comes to diagnosing problems with some common hardware setups. A problem …read more

Since its debut back in 2012 there have been a variety of inventive displays used with the Raspberry Pi. Perhaps you remember the repurposed Motorola phone docks, or you have one of those little displays that plugs into the expansion port. Inevitably the smaller options become disappointing as desktop displays, …read more

I did something silly. I bought a lot of ten “broken” cheesy indoor quadcopters on eBay — to hopefully cobble one working one together and to amuse my son. At this point, I’ve got eight working. The bad news is that they all come with dirt-cheap transmitters that aren’t really …read more
Recreating the arcade smash hit Pong in a device small enough to plug into a home television was a considerable technical challenge back in 1975. Of course, a big part of that was the fact that it needed to be cheap enough that consumers would actually buy it. But had …read more
If you’ve got a personal website that needs hosting or a few hundred gigabytes of files that could use a centralized storage location, the Raspberry Pi’s small size and extreme energy efficiency make it a compelling server choice compared to that curbside Pentium 4 box you’ve been trying to find …read more
