Automatic pool stick vs. strangers

An automatic pool playing robot – how hard could it be? Turns out harder than I thought. It took me quite a while to work through all the difficulties of this project but when it all finally came together is so worth it. To my surprise the most interesting aspect of this project is using the cue to play real games of pool over the internet. Let me know if you think twitch plays billiards would be worthwhile…

3D-printed mobile robot based on the Arduino Due

Although an Arduino can be a great way to provide computing power for a mobile robot, you’ll need a variety of other electronics and mechanical components to get it going. In his write-up, computer science student Niels Post outlines how he constructed a robotic platform that travels via two stepper motors, along with casters to keep it upright. Its round chassis is 3D-printed and runs on three rechargeable 18650 batteries.

This Gameboy Can Play N64, Sega Saturn, PSP and much More! The CM4 Boy

In this video we take a look at and test out the all new LCL CM4 Boy The CM4 Boy is an awesome Raspberry pi compute Modula 4 powered DMG Gameboy with and analog stick and enough power to run N64,PSP,Dreamcast and Sega Saturn and cabinet of running RetroPie,Recalbox or bat overs plus we have the option of using the built in HDMI port so we can connect this to much larger screen!

Arduino Powered Weather Balloon Datalogger

Hey everyone!! You’re probably wondering, wait, you can send an Arduino to space? Almost. Using a weather balloon, you can send an Arduino, camera, garlic bread, or anything else you want to a third of a way to space! Even though it is a third of the way to space, almost 99% of the atmosphere isn’t present, so we call it “the edge of space.” This guide is super long, but unless you are just checking this project out, make sure to read everything until Path 1. Anyways, let’s get into how you can do this.

Meet The World’s Smallest Portable N64

We’re all about a portable N64, but having one that fits in your hands and plays original cartridges is something we only thought the Nintendo gods could create.
But no, the modding maniac known as GmanModz is back at it again with the world’s smallest portable N64. He previously built the Nintendo 64 handheld that looked like a Gameboy Advance SP.
Somehow he has managed to modify a N64 console to fit in a tiny shell with the ability to play your best N64 games on the cartridges you still have hiding in your garage.

A Hi-Fi Speaker From Some Foil and Magnets

In the world of speakers, mass is the enemy of high frequency response. In order to get the crispest highs, some audiophiles swear by speakers in which the moving element is just a thin ribbon of metal foil. As the first step towards building a set of ribbon headphones, [JGJMatt] has designed a compact ribbon speaker made from aluminum foil.

A 3D-printed body holds six permanent magnets, which produce the static magnetic field necessary for the speaker to work. The sound itself is produced by a corrugated aluminum diaphragm made by taking a strip of foil and creasing it with a gear. Aluminum is difficult to solder, so electrical contact is made with a couple of short segments of copper tape. A little Blu Tack and glue hold it all together, and the result is stunning in its simplicity.

Gameboy Glasses Exist And They’re For Video Gamers With Eye Strain

Have you ever wondered what would happen if Nintendo released Gameboy Glasses for retro gamers? No, me neither, but the geeks over at Mutrics, have invented just that and we love it.

No they can’t play your best Gameboy Color games, but they can reduce eye strain, and connect to your smartphone to play audio through the built-in speakers at the back.

This bin will sort your trash and recyclables automatically

Often you might see a recycling bin next to a trash can, and notice that someone else has thrown their waste into the wrong container. To help with this conundrum, the team of Shalin Jain, Viraj Singh, Edward Chen, and Joshua Kim created a double-sided container that sorts things automatically.

Their device, dubbed “Splash,” takes a webcam image of the item presented to it, analyzes this with a Python script and the Azure Custom Vision API, and reports back to an Arduino Uno controller with its findings. Depending on the results, the Arduino then uses a driver board and motor to properly position a flap, directing refuse into in the correct bin.

Creating an over-engineered random number generator Arduino shield

Often when working with Arduino projects, you’ll need to generate a random number. There’s a random() function built into the IDE that works acceptably in many cases, but maker_ATOM wanted to take things to the next level, creating an “over engineered true random value generator.”

This device sits on top of an Arduino Uno as a shield, and features input from a floating pin seed value. It adds light input as a second seed value with an LDR, and ambient noise via a microphone as a third value. These are used to choose from an array of Pi digit values, which are also random, revealing outputs on its OLED display at the push of a button that would be exceedingly difficult to predict! 

More details on the project can be found in maker_ATOM’s Instructables post.
