As tired as I am after a long and difficult tow truck adventure this morning, I'm too excited to rest at the moment. I discovered devduck on YouTube and his Dauphin game. It's a RPG game where a marine biologist travels the world to clean it up and clean...
Revolution Pi is an open, modular, and durable industrial PC based on the established Raspberry Pi while meeting the EN61131-2 standard. Equipped with the Raspberry Pi Compute Module, the RevPi Core base can be expanded seamlessly using appropriate I/O...
A very quick update, with a new motherboard design. The concept with Iteration 8 is to have a science-tricorder-like device that fits on the back of a smartphone. The central challenges have been figuring out how to interface high-bandwidth sensors...
It is possible to read the GPIO (General Purpose Input Output) pins on the Raspberry Pi to record events from the Cosmic Ray Detectors. There is a library (Wiring Pi) which makes this access to the GPIO Pins really easy. Included in the software is a...
… that never was the question. Rather, the question was which SBC shall it be? During the last year we have tested quite a few Single Board Computers, as our project has specific requirements. During that time, SBCs have evolved enough to satisfy our...
"Navio+ is an improved version of Navio autopilot shield for Raspberry Pi A+/B+. It was designed both for your own custom robotic projects and as a platform for Linux version of APM (ArduPilot). Navio+ eliminates the need in multiple controllers onboard...
Finally got around to doing a few full 24 bit performance tests using the Raspberry Pi. Both THD+N and dynamic range were almost exactly what they had been using the Teensy as a test platform. Measured THD+Ns were -100dB on the left channel and -101dB...
I chose for this project to use a Raspberry Pi for the connected part, storing data, etc. Hovever, i also use a microcontroller (Atmega328p, because i have some, but a Attiny will also do!). I could have used the RaspberryPi GPIO to control the lights...
Well, there they are, the four prototypes:I played around a bit with connectivity options. So two PiDPs use a Raspberry Pi Model A+, the other two a Model B+. The machine in front has a slot on top to access the HDMI monitor connector (slot not necessary...
OverviewThe robot-avatar will have data sent/received using TCP/IP. The data we will be sending/receiving will comprise: commands for motor control (forward, left, right, back, control nerf gun), streaming video & audio from control computer to robot-avatar,...
As I've observed MQTT data there have been a few things I needed to tweak. Traditionally with ESPHome you would edit code through the console and click "upload". Since this device is deployed remotely I needed a way to update the code without going on-site....
The test start by building a bad looking DVP cable than can be inserted into the Orange Pi Plus's camera interface and that split each signal into individual wire that can be connected into the Lattice MachX03 development board. I use a 24 pins 0.5mm...
I soldered headers for two Pico W's. Unfortunately, one of the boards seems to be fried, or maybe it's a short-circuit that I need to go in and fix. Either way, my laptop wasn't recognizing it. Soldering iron was non-adjustable in terms of temperature,...
The Raspberry PiAs a router My original idea was to run a MITM and see if I could actually intercept the push notifications as my phone received them. I would have been fine not being able to decrypt/read them, I just wanted to know they were there and...
I researched Fast Fournier Transforms (FFT) on the Raspberry Pi and decided to implement it in this vest for gamers. I tested the vest using the Call of Duty game. The wearer can now feel the recoil when they shoot their gun and other bass sounds like...
