Controlling Traffic Lights with Micro Speech

A TensorFlow Lite Micro Speech model that detects wake words and turns on a different coloured LED light to emulate traffic lights.

Machine learning typically involves lots of computing power, and these are usually in the form of a large data center with GPUs and the costs of training a deep neural network can be astronomical. The emergence of tiny neural networks, which are as small as 14 KB, opens a plethora of doors to new applications that can analyze data right on the microprocessor itself and derive actionable insights (Warden and Situnayake, 2019). This saves time and prevents latency because we do not have to transmit data to a cloud data center for it to be processed and wait for it to come back (Warden and Situnayake, 2019). Such a phenomenon is called Edge Computing and allows for data to be processed and computed on the device that it is stored (Lea, 2020).

Coil Winding Machine Makes it Easy

[Mr Innovative] needed to wind some coils, and decided to make a machine to do the work. Making such machines has become a lot easier over the years. There was a time when we might probably have had to hack an old printer or scanner to get linear rods and stepper motors. Now, thanks to widespread 3D printing, we can order parts like that from lots of places. The 3D printing helps, too, to fabricate all the little custom widgets you need to put something like that together.

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.

How to Configure an ESP Mesh Network using Arduino IDE – Communicate among and between ESP32, ESP8266, and NodeMCU

Internet of Things (IoT) has seen exponential growth over the past couple of years. A new study from International Data Corporation (IDC) estimates that there will be almost 42 billion connected devices within the year 2025, generating over 80 zettabytes (ZB) of data. As the number of IoT devices grows; the amount of data grows, along with that, grows the need for superior network instruments; which can support this load.

However, if we consider a common host (like a generic router), it can connect to a limited number of nodes, less than 32 to be exact. And with an increasing number of IoT devices that could be in our home or industry, this is not sufficient. Currently, there are two solutions to this problem: The first one is to use a Mesh Router that can handle a lot more connections compared to a generic one, or we can use a network protocol known as Mesh Network.

LucidVR Budget Haptic Glove

A functional glove that lets you use (and eventually feel) your hands in VR.

This is a project to try to make VR Haptic Glove technology more available for the public. Currently, most VR Haptic Glove products out there are extremely expensive and are targeted for commercial use. In starting this project, I wanted to create a budget, but still well-functioning VR Haptic Glove that’s cheap and easy for people to get their hands on (or in, lol).

Super Mario Odyssey demake shows what it would look like as a 2D NES game

Super Mario Odyssey has been reimagined as an NES game to see what it would have looked like 30 years ago. And the best part? It’s free to download right now.

TeddyRoseKidd, a Twitch streamer and YouTuber has uploaded a video to his channel where he showcases exactly how he reimagined Super Mario Odyssey as a 2D NES game.

Drill Depth Display with Gyro Sensor

If you have to drill a certain depth for a project, you need a bench drill with depth display. Most bench drills have a ruler with an arrow for reading. The success of the drilling depends on how accurately you can read the desired position. In this Arduino project I present an alternative proposal: A drilling depth display with a gyro sensor and 7-segment display with Arduino support.

The machine I use most frequently in my workshop is not a saw or a grinding machine. It is by far the bench drill. Regardless of the project, it is actually always used. If I need a certain drilling depth, I can use the built-in ruler on the machine. And remember the depth to which I have to drill. It actually works well.

This Tiny 3D-Printed Dump Truck Is Remotely Controlled with an Arduino

Most of us have some experience with RC vehicles — at least the cheap toy variety. But those are just the start of what is available and the RC hobby is full of really impressive vehicles that put those toys to shame. Some are meant for speed and can outrun your Honda Civic. But others are designed to replicate their full-size counterparts as faithfully as possible. For example, it isn’t uncommon to see RC airplanes with accurate interiors. Redditor EnosCamare wanted to try their hand at a replica and built this adorable 3D-printed dump truck that is remotely controlled with an Arduino.

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.
