Making a PiPlateBot with the Raspberry Pi

Turtle robots of the yesteryears had always fascinated Robert Doerr and he decided to create one with the popular single board computer, the raspberry Pi or RBPi. He hid all components of the robot inside the plate case, and decided to call his robot PiPlateBot. Robert Doerr is the owner of Robot Workshop, and a dedicated robot builder. He used the Bud Pi Plate case, as this was strikingly similar to the turtle-style robots computer science students used earlier. The Pi Plate has a circular Read more [...]

HiFiBerry & Raspberry Pi Put New Life into Old Loudspeakers

If you have some old stereo speakers stored away in your basement, chances are they connect through the old way—with wires—to an amplifier, and that is the reason they were banished to the basement. With HiFiBerry Amp+ and a single board computer, such as the Raspberry Pi (RBPi), you can resurrect your vintage speakers. Using the latest in open source technology, you can now use the renovated loudspeakers wherever you want, since they now operate wirelessly. HiFiBerry offers their Amp+ as an Read more [...]

Raspberry Pi and Traffic Lights

Although we come across traffic lights almost every time we step out of our homes, we rarely stop to think about how they work. However, Gunnar Pelpman has done just that, and he has put the hugely popular single board computer, Raspberry Pi to good use. While most of the tutorials introduce turning on and off LEDs, he has prepared a somewhat more complex tutorial, one that teaches how to program traffic lights. Moreover, he has done this with the Raspberry Pi (RBPi) running the Windows 10 IoT Core. Traffic Read more [...]

Researching Hearing Aids with the Raspberry Pi

All around the world, millions of people benefit from wearing hearing aids. Apart from helping them to hear in a better way, hearing aids lower people’s risk of developing dementia, the likelihood for loneliness, and the possibility of their withdrawing from society. Testing hearing aids outside the laboratory can be a tough task, but researchers have found the highly popular single board computer, the Raspberry Pi (RBPi) a sound investment for testing hearing aid algorithms. Therefore, for hearing Read more [...]

A Google Assistant with the Raspberry Pi

This is the age of smart home assistants, but not the human kind. The last couple of years a fever pitch has been building up over these smart home assistants, and every manufacture is now offering their own version. While Apple offers Siri, Amazon presents Echo and Alexa, Microsoft wants us to use Cortana, and Google tempts us with Google Home Assistant, there are several more in the race. However, in this melee, Raspberry Pi (RBPi) enthusiasts can make their own smart speaker using the SBC. Although Read more [...]

What is Raspberry Shake and BOOM?

The Earth below our feet is never still. Although we feel tremors only when they are substantially strong, such as during earthquakes, we can use the highly popular single board computer, the Raspberry Pi or RBPi to monitor what is happening just under us. This tiny seismograph, with an appropriate name of Raspberry Shake, is the smallest one can find. Although small, Raspberry Shake can record earthquakes of all magnitudes, even those no human senses can detect. It is also capable of recording Read more [...]

Ethoscope with the Raspberry Pi

Although ethoscopes are very popular instruments for detecting or recording the real-time activity of fruit flies, they can potentially be used on other animals as well. The ethoscope platform is actually a collection of interconnected tools that biologists use when designing experiments, to capture and analyze huge amounts of behavioral data. The ethoscope uses a free and open-source set of tools, both hardware and software. The hardware is a Raspberry Pi (RBPi) while the software is built on top Read more [...]

Raspberry Pi Makes the Pac-Man Game Go 3D

Some avid gamers of today are not even aware of the video games that flourished in the seventies and the eighties. Those who have a collection of retro games may have given their children time to catch up with the old games. One such classic game from the 1980s, a very addictive one, was the pellet-guzzling arcade game with the name of Pac-Man, from Namco. One of the youngsters, Emanuele Coletta, has come up with a 3-D rendition of Pac-Man. Emanuele wanted to make something funny, while at the same Read more [...]

ATtiny Remote Power Switch for the Raspberry Pi

One of the shortcomings of most highly popular single board computers such as the Raspberry Pi (RBPi) is the lack of an on/off power switch. The board springs to life as soon as you insert the micro USB power cable into its socket. If you simply switch off power or pull out the micro USB cable off the RBPi, you stand the risk of not only losing data but also of corrupting the file system. Therefore, to shutdown the RBPi safely, you need to call a shutdown command, which closes down the file system Read more [...]

ElectroSmash Pedal for the Raspberry Pi

Guitarists favor expensive gear. For instance, they hold online discussions about the best types of wire for guitar pickups. They even go to great lengths while selecting the type of transistors that will give them the best fuzz tone. They hold extensive discussions about the merits of the pentode rectifier over the tetrode type. While the geeks in the electronics world share several common characteristics with the guitar geeks, the ElectroSmash Pedal Pi would interest both. Both teams are already Read more [...]
