Circuit-Sword Delivers Retro Justice

You can’t search for “retro gaming” without hitting a plethora of single board computers attached to all manner of controls, batteries, etc. Often these projects have an emphasis on functionality above all else but [Kite]’s Circuit-Sword is different. The Circuit-Sword is the heart of a RaspberryPi-based retro gaming machine with an enviable level of fit and finish.

Fundamentally the Circuit-Sword is a single board computer built around a Raspberry Pi Compute Module 3. We don’t see many projects which use a Compute Module instead of the full Pi, but here it is a perfect choice allowing [Kite] to useful peripherals …read more

Raspberry Pi Gets Faster CPU and Better Networking in the New Model 3 B+

While the Raspberry Pi’s birthday (and the traditional release date for the newest and best Pi) was a few weeks ago, Pi Day is a fitting enough date for the introduction of the best Pi to date. The Raspberry Pi 3 Model B+ is the latest from the Raspberry Pi foundation. It’s faster, it has better networking, and most interestingly, the Pi 3 Model B+ comes with modular compliance certification, allowing anyone to put the Pi into a product with vastly reduced compliance testing.

A Small Speed Boost For The CPU, A Huge Leap For The LAN

When the Raspberry …read more

PipeCam: Shallow-Water Exploration with Raspberry Pi

In what began as a personal challenge he issued to himself, [Fred] is in the process of building an underwater camera that’s capable of long-term photography in shallow waters. He’d like it to last about five hours on a charge while taking a photo every five minutes. Ideally, it will be as cheap as possible and constructed from readily available parts. Solving the cheap/available equation would theoretically make the camera easily to replicate, which is the third major requirement.

[Fred] has recently made great strides, both in the circuitry and the capsule design. The latest version uses a Raspberry Pi …read more

Haunting A Smart Mirror With Hue and Alexa

So, your smart mirror has been running for a while, but Halloween is coming up and you want to come up with some cool Halloween stuff to display on the mirror. If you’re looking for ideas, check out [Ben Eagan]’s cool Haunted Smart Mirror which connects the mirror via a Raspberry Pi with Amazon Alexa and Phillips Hue lighting.

[Ben] points to another of his blog pages for those readers interested in the nuances of setting up Alexa with a smart mirror, while concentrating on communication with the Hue bridge and creating the setup for a new Alexa command in …read more

Networking: Pin the Tail on the Headless Raspberry Pi

Eager to get deeper into robotics after dipping my toe in the water with my BB-8 droid, I purchased a Raspberry Pi 3 Model B. The first step was to connect to it. But while it has built-in 802.11n wireless, I at first didn’t have a wireless access point, though I eventually did get one. That meant I went through different ways of finding it and connecting to it with my desktop computer. Surely there are others seeking to do the same so let’s take a look at the secret incantations used to connect a Pi to a computer directly, …read more

Introduction To TensorFlow

I had great fun writing neural network software in the 90s, and I have been anxious to try creating some using TensorFlow.

Google’s machine intelligence framework is the new hotness right now. And when TensorFlow became installable on the Raspberry Pi, working with it became very easy to do. In a short time I made a neural network that counts in binary. So I thought I’d pass on what I’ve learned so far. Hopefully this makes it easier for anyone else who wants to try it, or for anyone who just wants some insight into neural networks.

What Is TensorFlow?

Gaming Beyond Retropie

Looking for something a bit more from your Raspberry Pi? Tired of the usual console and arcade games? Eltech’s Exagear Desktop is a virtual machine that runs on your Raspberry Pi and allows you to run x86 games. [Dmitry]’s done a write-up about running more modern games on your Raspberry Pi.

Up until now, the Pi has been a great platform for retro gaming. By running MAME or EmulationStation, you can play classic arcade games as well as the great console games you played as a kid. Exagear Desktop goes one further, allowing you to use Wine to play more …read more

Using SDR to Take Control of Your Home Security System

[Dan Englender] was working on implementing a home automation and security system, and while his house was teeming with sensors, they used a proprietary protocol which was not supported by the open source system he was trying to implement. The problem with home automation and security systems is the lack of standardization – or rather, the large number of (often incompatible) standards used to ensure consumers get tied in to one specific system. He has shared the result of his efforts at getting the two to talk to each other via his project decode345.

The result enabled him to receive …read more
