[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.
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).
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.
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.
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…
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.
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.
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.
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.
Drones are fun to fly, and it’s possible to do limited flying using brainwaves. The headset senses my brainwaves and transmits them to a small computer. When I increase my attention level, the computer converts the signals and passes them to the drone’s controller, which I have connected to the computer. When I relax my mind, the drone lands.
