I’ve used off-the-shelf wireless charging kit to add wireless charging to my Logitech MX Master 2S mouse and Lenovo keyboard. It’s easy, fun and also very convenient.
I keep losing my TV remote and then spend embarrassing amount of time searching for it… So I figured, obviously I’m not getting better at finding it, so I’ll make the TV remote better! 🙂 Enter ESP32 WiFi Remote.
As always, all the source files that you need to make one by yourself are available for download on GitHub.
In this video I’m going to show you how to create a nice touch controller for your light setup. Using a voltage regulator to control the brightness and touch sensor to turn it on and off, you can build an awesome controller to turn on and off your lights or any other DC powered unit.
In this video I’m going to show you how to build a night light or ambient light for your room, but you can use the same guide to light up your media room, book shelve, display case or anything else that you want to. This project is quick and super easy to build so it’s perfect weekend project. Also, all parts are easy to get and available off the shelf and end result is… awesome!
DigiKey Fetch Tool helps you when working on bill of material (BOM) for your projects. This simple Python script will fetch all relevant information about a part (Manufacturer, Manufacturer Part Number etc) and allow you to paste/type that information into any application using global hotkeys. This saves a significant amount of time by removing the need to do many alt+tab and copy&paste operation to copy information from your distributor’s website.
See it in action
In the video above, you can see first a power up sequence where all four dials go from zero to 100% and back to zero after which they start showing real time CPU, Memory, Network and GPU usage. After that we run a internet speed test to show how the real-time information is displayed on the dials.
First, let’s see it in action
It’s a bit hard to capture how this clock really looks, especially since my camera doesn’t really appreciate when there are sixty LEDs glowing into it. Trust me, it looks even cooler when you see it live.
While ago I backed up a SPIDriver’s crowd supply campaign to make an open-source, open-hardware SPI tool. Even though I have plenty of professional tools to do this job, but at $30 it was worth buying this tool even if I never end up using it, right? Two weeks ago I received it in the mail and gave it a quick demo run; it looked great, worked as expected but I didn’t had a real chance to put it to the test. Last week there was an issue on the production line and few bricked units ended up on my table. Since I needed to extract data from the SPI Flash and analyze it, I though this was a perfect opportunity to put the SPIDriver to the test.
Making a IoT LED dimmer that you can control via your PC, phone, tablet or any other device connected to the network is super simple, and I’m going to show you how.
I’m sharing my three channel LED dimmer that you can use to dim single RGB LED strip or dim three separate LED channels. I want to be able to control lights above my desk and also mix warm white and cool white strip to give me more flexibility over lighting while I’m working, taking pictures or watching movies.
This is going to be a very short and very simple project that if you follow steps below, you can build it in an hour (excluding lead time for components).
