Multimeters are one of the most essential tools for working with electronics. Learn how to use a multimeter to check continuity and to measure continuity, voltage, resistance, and current. Then, learn some troubleshooting tips and best practices. If you’re new to electronics or just want to brush up on how best to use this valuable tool, be sure to check out this video by @BeckyStern

Here’s how to make a super functional and stylish canvas backpack from scratch. Whether you need something for everyday carry or a weekend adventure, this bag is sturdy, customizable, and beginner-friendly.
The final bag dimensions are 34cm tall by 24 cm wide by 12cm deep (13.5 inches tall by 9.5 inches wide by 5 inches deep).
For the Ikea-specific colorway, here are the
Today, we’re taking a look inside the Belkin Auto-tracking Stand Pro. We’ll try it out, take it apart, and analyze the design and manufacturing of the circuitry inside.
So here’s the Belkin Auto-Tracking Stand Pro. It’s got a simple but solid design. Snap your phone into the Magsafe connector, and the stand automatically rotates to track you. It’s a cool piece of tech, and the first product to use Apple’s new DockKit accessories standard. Previously, products like this would be limited to capturing with their own apps, but now the DockKit system allows the stand to seamlessly integrate with the native camera app while capturing content or during video calls.
It has a battery inside, which makes it portable and a tripod mount on the bottom. It moves super smoothly and quietly, so I’m curious what’s going on inside.
If you are curious about connectors, but don’t know where to start, this video will quickly bring you up to speed. Explore the many different low-voltage connector types that you can use in your projects in this video by @BeckyStern

Today we’re taking a look inside the two most popular continuous glucose monitors, or CGMs: The Abbott FreeStyle Libre 3 and the Dexcom 7.
Originally developed for diabetes blood sugar monitoring, CGMs are gaining wider appeal among nondiabetics looking to track their metabolic health. It feels pretty cyborg to wear a biosensor that streams data to my phone over Bluetooth.
Here’s a guide I’ve been meaning to make for a while– consider it your jumping-off point if you want to get started making your own wearable tech. I’ve published dozens of DIY wearables projects over the years, from LED costumes to Internet-connected sensor jewelry. Here are my best tips for beginners, including answers to common questions.
The first thing you need to get started is an idea. Think about solving a problem or enhancing an experience, either for yourself or someone you know. Maybe there’s a costume or cosplay you’ve always wanted to wear.
The second thing you need is the curiosity, drive, and resourcefulness to learn the skills needed for your idea, which you do not already possess. I’m hoping this guide will help with some of that.
The final thing you need is some motivation to start and/or finish your project, which may come from within, or maybe an event or contest.
It’s important to evaluate your skill level and bite off an appropriate amount of new material to chew on, so as not to get too frustrated to finish your project. Work smarter, not harder. Readymade battery-powered fairy lights, LED strips, and EL wire are perfectly acceptable materials, especially if you’re not ready to take on microcontroller programming or soldering.
(more…)Welcome to another teardown! This time we’re taking a look at the CurrentBody LED red light therapy mask. Masks like these promise to improve various signs of skin aging.
This project was a collaboration across three continents: my friend Michelle from Lab Muffin Beauty Science in Australia, my other friend Ruth Amos in the UK, and myself (in NYC). We were very curious about these devices. How do they work? What’s the science backing up the marketing claims? Is it really worth the $400 price tag? Could we make a DIY version? We all got on the horn to talk about it.

This year for YouTube Makers Secret Santa, I got Look Mum No Comupter. Sam performs with his modular synth and other cool audio equipment and collects obsolete technology for his museum in Kent UK. We share a love for hacking toys and other ways to use electronics to be creative. I built him an audio sequencer in an old PS4 controller using sounds from his museum’s sample packs.
