Automatic Cereal Dispenser With Facial Recognition

A device that automatically dispenses cereal when a face is recognized on a Raspberry Pi camera running OpenCV.

Breakfast is arguably the most important meal of the day. Nearly a quarter of individuals in the U.S do not eat breakfast and this mainly due to not having enough time in the mornings. I believe that time is not the issue robbing us of our sweet sustenance and is a simple fact that cereal boxes are too heavy. I wanted to create a machine that would use Artificial Intelligence to detect specific people and pour the cereal they like for them to conserve the critical energy that is needed to tackle the day. Picking up a cereal box has gotten more and more difficult throughout the years with the increase in cereal box size. To combat the strain to muscles that daily cereal box pouring can cause, my device makes it easy to keep your weak muscles safe and nourished.

RaspberryPi Assisted ‘Anti-Mosquito Laser Turret’ Has Been Developed

Russian computer scientist named Ildar Rakhmatulin produced a mosquito laser using Raspberry Pi and laser. An expert working on brain-computer interfaces at Russia’s South Ural State University claims that with his invention, he neutralized two mosquitoes per second.

” Raspberry Pi to kill mosquitoes laser ” online as a non-peer reviewed preprint in January. In it, he lays out a plan to snipe mosquitoes out of the air using a Raspberry Pi equipped with a Pi camera, a galvanometer that detects electrical currents, and a commercially-available laser pointer that’s 450 nanometers and one wavelength—powerful enough to kill a mosquito and blind someone looking directly at it, but not enough to burn skin.

Robin Grosset Takes a RaspberryPi Pico’s RP2040 to New Heights with an Overclock to 420MHz

Impressive overclock boosts the RP2040’s Arm cores to more than three times their official upper limit of 133MHz.

Engineer Robin Grosset has pushed a Raspberry Pi Pico and its RP2040 microcontroller to its limits, successfully overclocking the chip from its stock 133MHz to an impressive 420MHz.

Launched earlier this year the Raspberry Pi Pico development board plays host to Raspberry Pi’s first in-house silicon, the RP2040 microcontroller. Officially, the chip can be clocked at speeds of up to 133MHz — but unofficially the part can run considerably quicker, as is often required to get the best performance out of hacks like turning one into a fully-functional BBC Micro emulator.

Thomas Megel’s OpenScan Offers 10-Micron 3D Scanning on a RaspberryPi and HQ Camera Module

Low-cost 3D-scanning system offers sub-30-micron accuracy on a cheap Raspberry Pi Camera Module v2.1, or 10-micron on the HQ Camera.

Thomas Megel is aiming to bring down the cost and complexity of accurate 3D scanning — and to prove it, he’s scanned a Raspberry Pi single-board computer using another Raspberry Pi single-board computer.

Machine Learning Inference on Raspberry Pico 2040

This is another article in know-how series, which focuses solely on a specific feature or technique and today I’ll tell you how to use neural network trained with Edge Impulse with new Raspberry Pico 2040. Also make sure to watch the tutorial video with step-by-step instructions.

Edge Impulse is a platform that enables developers to easily train and deploy deep learning models on embedded devices. You can read the full introduction in my first article of the series about TinyML. Now, let’s jump straight to action.

MicroNova’s AmpliPi Is a RaspberryPi Powered Open Source Audio System for Your Entire Home

Driven by a Raspberry Pi Compute Module 3+, this Python-powered audio system supports up to six stereos zones — expandable to 36.

MicroNova has launched a crowdfunding campaign for AmpliPi — an open source, whole-home audio system powered by a Raspberry Pi Compute Module 3+ and running a Python REST API and mobile-first web application.

“AmpliPi is a multi room/zone home audio controller and amplifier made for whole house audio systems with many zones,” explains MicroNova co-founder Jason Gorski of the device. “It can play up to 4 simultaneous audio streams (Pandora, Spotify, AirPlay, etc) or sources (RCA inputs), each routed to one or many zones, all of which are configurable in real-time using the self-hosted AmpliPi Web App or its underlying REST API.”

This RaspberryPi Pico-Based Macro Keyboard Features a 3D-Printed Circuit Board

As makers, we are extremely lucky that today we can have affordable, professional-level PCBs fabricated on demand in small quantities and shipped to our doorsteps in just a week or two. Those are absolutely your best option if you’re working on projects that require custom boards and you want them to come as close as possible to consumer devices. But the week or two it takes to get PCBs fabricated and shipped can be too long for quick projects and you may not want to spend the money anyway. That’s why Redditor Duzitbetter came up with a really clever way to 3D print the circuit board for this Raspberry Pi Pico-based macro keyboard.
