Hardware and Firmware Engineer
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.

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!
Leave a CommentDigiKey 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.

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.
I am very pleased to announce that this project has turned into a product!
Thanks to collaboration with Streacom, you can now purchase VU Dials.
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).
Making a BOM (bill of material) for projects and keeping them up to date is really important. But also it is a tedious task that few people enjoy.
In effort to improve workflow when creating new components or updating existing ones, I have create a Python script that will fetch all important data for a component that you might want to use.
This tool has greatly reduced number of alt+tab / copy & paste juggling from my creating/maintaining BOM workflow, and I hope it does the same for you.

This one is a very simple but cool project, something that I would recommend to anyone who is interested into DIY electronics, gadgets and learning new stuff in general. It is definitely one of those projects that don’t require too much time but you can learn a lot by making it and also earn a lot of credit by sharing it with your friends and family.
Below you can see a final product. It’s a heart shaped, touch sensitive, keychain for your loved ones. On the front side there is a smiley face drawing that has eyes and mouth. Eyes have two red LEDs that will start to pulse once you touch the keychain or place you finger on the smiley face (see it in action below)
