While a keyboard and mouse work well for general computing tasks, if you really want to get your button-mashing on, then you need a stick setup with buttons and a joystick. Unfortunately, not all o… → Read More
Power Supply Rail Splitter
When outfitting your electronics workbench, one of the most essential tools is a variable DC power supply. In fact, I’d argue it’s firmly in the top 5. Such power supplies typically fea… → Read More
AiryFi ESP8266 Air Quality Monitor
As you go about your day-to-day life, you probably have some vague understanding that there is air pollution around you. However, actually putting a number on how air quality changes from one day, … → Read More
USB-C Cable Tester
USB Type-C, or simply USB-C, is an interesting beast. On the one hand, the fact that it’s reversible is amazing when compared to its predecessors, and USB-C’s potential data tran… → Read More
WiFi and BLE Capable ePaper Dev Board
An ePaper display can be a fantastic solution when you need to show static or slowly changing information. Since this type of display uses power only when swapping states, they can be great for low… → Read More
USB Type-C 2.0 Breakout Board
USB, or Universal Serial Bus, was a rather fantastic idea when it was released in the 1990s. No longer would we need a separate serial port, parallel port, game port, PS/2 port, etc. We could simpl… → Read More
Coin Cell Battery Emulator
Coin cell batteries power many an embedded electronics project, and are excellent if you need a tiny bit of power in a compact size. Because of their minimal power capacity–3V in the 200 mAh range … → Read More
Blinky Adds Labels and Diagnostic Lights to Raspberry Pi SBCs
While Raspberry Pi single-board computers are generally fantastic, one frustration with them (besides availability) is that the GPIO pins are unlabeled. This can leave you guessing and/or searching… → Read More
CAT-CAT Walker Soldering Kit
PCB Soldering kits come in all shapes and sizes, but few allow you to make a walking–or at least sliding–electronic device in an hour or so. The CAT-CAT Walker kit by Patchr does just that, featuri… → Read More
uMyo: Wireless EMG Device
EMG, or electromyography, is a technique for measuring electrical muscle signals. It can be used for diagnostics, and such signals can also be applied to control prostheses or other devices. While … → Read More
Hands-On With the USB-C PDTricker
Last month I wrote an article about the PDTricker Fast Charge Deception Tool by MuseLab, and like many products I write about here I was tempted to get one. My presumptive use case is that while I … → Read More
9V LED Lighting Kit Drains “Dead” Batteries
Nine-volt power pack batteries are used for various purposes, but perhaps most commonly these days they often power smoke alarms. As such, one needs to change them well before they’re fully d… → Read More
Tindarians at Maker Faire Orlando 2022
This weekend (November 5th and 6th, 2022) marked the 10th annual Maker Faire Orlando, a rather large event that features everything from electronics, to art, cosplay, robot fighting, 3D printers, e… → Read More
PDTricker Fast Charge Deception Tool
The PDTricker Fast Charge Deception Tool by Muse Lab connects to a USB-C PD source, and can produce voltages on an output USB-C port of 5, 9, 12, 15, and 20V. Voltage selections are made via an onb… → Read More
3D-Printed PCB Test Jig
While I write for Tindie, I also sell things on the JC Devices store. My most successful product is the EZ Fan2 board, which is meant to help control a simple fan (or any other small load) with Ras… → Read More
Solve Steam Deck Cooling Issues With This Extreme Solution
Valve’s Steam Deck is a fantastic piece of hardware. However, like all advanced computing devices it generates heat, and being in a small enclosed form factor this thermal energy doesn’t alwa… → Read More
LoRaWAN GPS Tracker
LoraWAN is a fantastic wireless protocol, designed to use very little power while transmitting small bits of data over several kilometres or more (depending on conditions). Combine this tech with a… → Read More
Foxie Clock 2.0 is an Edge-Lit Masterpiece
Clocks come in all shapes and sizes, but you’d be hard pressed to find one that combines a retro feel, with modern technology and excellent craftsmanship, better than the Foxie Clock 2.0. The devic… → Read More
Snag-Free Ethernet Cable Puller
Installing Ethernet cable is a great way to enhance speed, range, and/or latency in your network. That being said, considering the staggering number of 1s and 0s flowing through through these wires… → Read More
