Count down to Christmas with an Arduino-powered Hackvent calendar

3 days 5 hours ago

Along with the typical Christmas decorations of trees and elves sitting on shelves, Tom Goff was motivated to build a DIY “Hackvent” calendar after being inspired by his son’s request for one. The project differs from the traditional Advent calendar in that it features an array of two dozen colored lights — one for December 1st to 24th […]

Schematic-o-matic automatically creates KiCAD schematics from your breadboard

3 days 21 hours ago

Breadboards are the first tool you break out in any prototyping journey and almost every project will utilize a breadboard at some point. Those breadboards often turn into a rats’ nest of overlapping wires that are difficult to trace, which makes it difficult to create an accurate schematic when it is time to design your […]

Converting a Fat Cat cushion into a controller for Final Fantasy XIV

1 week 3 days ago

Mounts in the video game Final Fantasy XIV act like how cars or horses do in our world since they allow players to travel around the map much faster than would otherwise be possible. But even better, mounts are ways to express personality and have some fun, which is especially evident with the infamous “Fatter […]

Meet RobBob, a 3D-printed robot head that works with an N64 controller

1 week 6 days ago

Inspired by a special two-axis mechanism that uses a pair of beveled gears to create panning and tilting motions, maker and YouTuber JBV Creative wanted to integrate it into a larger kinetic sculpture that could move electromechanically while also looking great at the same time. This led to the creation of RobBob, which is essentially a robot-shaped head […]

This Portal fan brought Wheatley to life as his own personal assistant

2 weeks 3 days ago

The video game Portal 2 is widely regarded as a classic that introduced players to several memorable characters, including one of the main protagonists-turned-antagonists, Wheatley. This anthropomorphized personal assistance robot was able to move, speak, and listen/respond to speech from a user, which is exactly what Steve Turner was trying to recreate when he built his own […]

This tinyML system helps soothe your dog’s separation anxiety with sounds of your voice

2 weeks 5 days ago

Due to the ongoing pandemic, Nathaniel Felleke’s family dog, Clairette, had gotten used to having people around her all the time and thus developed separation anxiety when the family would leave the house. But thanks to some clever thinking, Felleke came up with the idea to automatically detect when his dog started to bark and play […]

Hacking a USB battery bank to gather telemetry

2 weeks 5 days ago

USB battery banks are a dime-a-dozen and useful for recharging all of those devices in your life. But the typical cheap battery banks don’t provide you with much information about their status. You usually just get a few LEDs that provide a very general idea of how much battery life remains. Keenan Johnson needed more […]

Opa is an open source boat bot that navigates the open water

2 weeks 6 days ago

Starting with an idea in 2019, Redditor wesgood has been steadily working on the Opa — an autonomous 3D-printed boat that can navigate open water while relaying its telemetry back in real-time to a client device over WiFi. After creating a small prototype, Wes built a second one that featured a pair of pontoons held together with a […]

Cascading LED stair lights prevent late night tumbles — and put on a show during parties

3 weeks ago

Stephen Gidge and his roommate have a poorly-lit flight of stairs in their home. That isn’t a big deal during the day, but it is a recipe for late night tumbles. They could have setup some nightlights or installed a new hall light, but they were both experienced with Arduino and so they created these […]

Perfect your virtual production setup with this RGBW ceiling light

3 weeks ago

Integrating a green screen into a video or image is not as simply as merely tossing a green sheet onto a wall and calling it a day since the subject’s lighting also needs to match the lighting in the scene behind them. But rather than spending a fortune on specialty lighting or taking way too […]

This MKR WiFi 1010-based weather station sends readings to the Arduino Cloud

3 weeks 2 days ago

Constructing your very own IoT weather monitoring station can be a complicated ordeal, as getting values from the embedded device to some kind of web server in a secure manner takes a lot of effort and time to complete. For his system, Clem Mayer from element14 Presents was able to use a MKR WiFi 1010 […]

Time to put this DIY absolute position encoder to work as a clock

3 weeks 5 days ago

Being able to derive the absolute position of an object is vital in countless applications, primarily for anything that uses a motor. Instructables user holybaf had the idea to build their own rotary encoder, which has 60 degrees of resolution and utilizes a CD to act as a precise clock. To accomplish this, they first laid down a […]

James Bruton built a robot that moves like an earthworm

3 weeks 5 days ago

Self-propelling robots come in a whole host of shapes, sizes, and capabilities, with some being able to fly while others can walk on just a couple or many legs. But YouTuber James Bruton wanted to innovate on this concept even further by designing and building a robot that mimics an earthworm through extending and contracting segments at certain times […]

FarOut extends the range of Kinect-based touch sensing

3 weeks 5 days ago

Capacitive touchscreens today use a digitizer to pinpoint the coordinates of a finger tap. That makes sense for smartphones and tablets, but isn’t ideal for large scale applications. If you want to recognize touches on the scale of an entire wall, a Kinect sensor could be more appropriate. But such a setup traditionally has a […]

This MP3 player is controlled with a twirl of your finger and wave of your hand

3 weeks 6 days ago

The classic MP3 player was a truly innovative device for its time, however with the advent of modern smartphones and other do-it-all gadgets, they have largely fallen by the wayside. In order to add a new twist, Norbert Zare decided to implement an MP3 player that not only responds to user inputs by moving the volume knob and tilting […]
