Interested in making a useless box? Building this project was a really fun experience for me. Having very little prior knowledge about circuits, making this simple gadget was a great introduction to circuits for me. And, it’s really fun to play with once completed! This project is meant for beginners with little or no experience […]
So much of our lives is spent making choices. Cut down on that time by making your own “Don’t Make Me Choose” project. This project uses the lights on a Circuit Playground to point to a specific item you have listed on the whiteboard. This project is great for choosing a date night activity, place
Don’t Make Me Choose – a Randomized Light Wheel Continue Reading
This Li-Po/Li-ion Arduino charger shield is mainly designed to power up the Arduino from single 3.6V Li-Po battery. Li-Ion and Li-Pol Charger/ DC-DC Boost converter Arduino shield provides 6.5V/400mA from single Lithium Polymer battery. The Arduino shield is equipped with BQ21040 battery charger IC and CS5171 step up DC-DC converter. The shield also has prototype area to utilize the maximum area

Raise you’re hand if you’ve ever soldered directly to a battery even though you know better. We’ve all been there. Sometimes we get away with it when we have a small pack and don’t care about longevity. But when [Robert Dunn] needed to build a battery pack out of about 120 Lithium Ion cells, he
With the world opening up again, [Niklas Roy] and [Kati Hyyppä] have been busy making a public and collaborative project. Meet the Vektor Kollektor, a portable drawing machine experience, complete with a chip-tune soundtrack. It’s great to see public art meet the maker community with zero pretension and a whole lot of fun! The build started
Walking robots were once the purview of major corporations spending huge dollars on research programs. Now, they’re something you can experiment with at home. [Technovation] has been doing just that with his micro quadruped build. The build runs twelve servos – three per leg – to enable for a great range of movement for each limb.
We’ll admit we are suckers for clock projects, and the more unusual, the better. We liked the look of [Peter Balch’s] astronomical clock, especially since it was handcrafted and was a relatively simple mechanism. [Peter] admits that it looks like an astronomical clock, but it isn’t the same as a complex instrument from medieval times. Instead,

One of the most beautiful features which the ESP32 has over the ESP-12e is the fact that, asides the WiFi, it has two other communication modules onboard. The ESP32 comes with an onboard Classic Bluetooth and Bluetooth Low Energy modules. For today’s tutorial, we will explore how the Bluetooth Low Energy Module onboard the ESP-32 can be used in projects. INTRODUCTION TO BLUETOOTH LOW ENERGY
The MAXREFDES96# from Maxim Integrated Products is an Arduino Uno R3-compatible board that provides battery charge, boost, and data-logging capabilities. The board can be operated tethered to a power supply or computer to charge a battery and operate untethered to use the battery to power the Arduino board. Typical applications are expected to include charger/fuel gauge evaluation and portable

Our first thought was that having big fins coming out of your VR goggles might not look very cool. But then we realized if you are wearing VR goggles, that’s probably not your biggest concern. (Ba-doom, tss.) Seriously, though, high-intensity graphics can cause your phone or device to get pretty toasty up there pressed against
