Raspberry Pi Hidden Settings - Setup Hostname, SSH and WiFi from the Pi Imager Application. - Uncover a hidden screen in the Raspberry Pi Imager Application to easily set up SSH, WiFi, and hostnames for your device without creating additional files. Just press Ctrl+Shift+X!

ESP32-S3 Hardware SPI on the Adafruit ST7789 - I've had some commenters point out the issue with the slow display updates in my recent Arduino Nano ESP32 video. It turns out, the software SPI of the Adafruit_ST7789 library was the culprit. Lo and behold, the solution is simple - using the hardware SPI constructor of the library. Apparently, this isn't well documented, so I wrote some code to serve as reference for myself and others who might run into the same snags. Trust me, the difference in speed is absolutely bonkers. Check out the video to see the magic in action.

Flashing the TS80P with IronOS - In this blog post, I explore the TS80P soldering iron, a tool that has been generating buzz. One of the highlights is that its firmware can be flashed with an open source system called IronOS. Here, I share my process of flashing the TS80P with IronOS and testing it out on a Raspberry Pico W. Please note, a Quick Charge or Power Delivery supporting power supply is needed for this iron. While running some tests, I observed that using a fast charger can heat this iron up twice as fast as using an Apple charger. Also, flashing the firmware is straightforward but you might need a little patience if you are using a basic USB supply.

ESP32 TV Version 3 - In the latest board revision, I've successfully resolved some key issues, including a USB interface conflict between the USB2244 and the ESP32 and a risky battery charging mistake—no more direct USB 5V to the battery! Plus, I managed to wrap this up without any clumsy bodge wiring. I've even introduced a new feature: a microphone is now on board, setting the stage for some exciting future projects. Stay tuned for what's coming!

Decoding AVI Files for Fun and... - After some quality time with my ESP32 microcontroller, I've developed a version of the TinyTV and learned a lot about video and audio streaming along the way. Using Python and Wi-Fi technology, I was able to set up the streaming server with audio data, video frames, and metadata. I've can also explored the picture quality challenges of uncompressed image data and learned about MJPEG frames. Together with JPEGDEC for depth decoding, I've managed to effectively use ESP32's dual cores to achieve an inspiring 28 frames per second. Discussing audio sync, storage options and the intricacies of container file formats for video storage led me to the AVI format. The process of reading and processing AVI file headers and the listing subtype 'movi' allowed me to make significant headway in my project. All in all, I'm pretty chuffed with my portable battery powered video player. You can check out my code over on Github!

Forget SSH and vim, Use VSCode to Remote Develop on the Raspberry Pi - In this blog post, I share how you can avoid hassles of SSH and use VSCode for remotely developing on the Raspberry Pi. I walk through how to initially configure the Pi in a headless setup using the Pi imager app. Then, we install the 'Remote Development' extension in VSCode. I illustrate how easy it is to connect to the Pi using our SSH credentials, clone a GitHub project, and install python extensions. Finally, I explore how to run the code and debug it. However, note that the method doesn't support armv6, so you can't use it on Pi Zero.
