I recently bought a Hantek DSO5102P oscilloscope, everything work, except the "Save To USB" button doesn't actually save any data to the USB. This is a short article on how I find the solution for the problem. Continue reading "Fixing Hantek DSO5102P “Save to USB” issue"

NTP Clock Project Revisit and ESP8266 RTC Memory
When I built the NTP Clock project two years ago, I did a quick estimation that the battery will last for about 80 days for a single charge. I was wrong, it only last for 47 days. Of course, my original estimation was not precise but I was wondering why my estimation was far away from my estimation, so I recently decided to take a closer look.

Build a PalmTop handheld with STM32G070
For many makers, a project idea sometime may take a very long time to materialised. This project for creating a STM32G070-based PalpTop handheld took me almost a year, starting from the initial idea, to making the final PCB, and still not 100% completed yet. Continue reading "Build a PalmTop handheld with STM32G070"
Make megaTinyCore work for PlatformIO
The megaTinyCore work great when using with Arduino IDE, but not so with PlatformIO. This is my quest on making the megaTinyCore work for PlatformIO. Continue reading "Make megaTinyCore work for PlatformIO"
Install PHP on Apple Silicon Macbook Pro
I recently went through the process of install PHP on macOS Monterey on my MackBook Pro M1 (Apple Silicon), the installation of PHP itself is easy, the codesigning of the PHP module took a little while to figuring out, I thought it would be a good idea to document the walk-through on how I did it. Continue reading "Install PHP on Apple Silicon Macbook Pro"
ESP8266 NTP clock with NTP update and Charlieplexing
I had a classic Ikea clock that damaged by the leaking battery, during the new year cleaning, my family decided to throw it away, I took it back from trash bin and thinking of a weekend tinkering project to turn it into a digital clock. Continue reading "ESP8266 NTP clock with NTP update and Charlieplexing"
A better way to setup STM32CubeIDE
I have been using STM32CubeIDE for my STM32 development for past a couple of years, and there are things that I like about the IDE but there are also things that I don't like about it. In this blog I'd like to discuss how I setup the IDE to overcome some of the things that I don't like about the IDE. Continue reading "A better way to setup STM32CubeIDE"
Converting UYue Preheater into a Solder Reflow Hot-plate
This article talks about how I hack a UYue 946 preheater and convert it into a solder reflow hot-plate. Continue reading "Converting UYue Preheater into a Solder Reflow Hot-plate"
The simplest button debounce solution
Recently I came across a piece of code which is nearly 50 lines long, plus several global variables, a state machine, all it does is to debounce two buttons. Button debounce does not to be this complicate, in this article I will show you probably the simplest button debounce solution. Continue reading "The simplest button debounce solution"
How to Install STM32CubeIDE on Mac and STM32 LoRa Discovery Kit
Recently I got two STM32 LoRa Discovery boards(B-L072Z-LRWAN1) for my LoRa project, and I need to install STM32CubeIDE and an STM32 Expansion Package i-cube-lrwan in order to use the board. It took me a while to figure out everything and I thought it would be good to share how I set everything up. Continue reading "How to Install STM32CubeIDE on Mac and STM32 LoRa Discovery Kit"
