I Feel the Need – The Need for Hardware SPI… An insightful iteration on my Arduino Nano esp32 video. Despite criticism regarding the slow display update speed, a solution was found thanks to the helpful fellow, Nick. Turns out, the software SPI was the cause of the issue. A quick tweak in the code and voilà , we've got ourselves an SPI clock whizzing at 80 megahertz. Quite the speed boost for just a few lines of code alteration! 29 October 2025
Arduino Nano ESP32 - It's nice - But probably not for me. In this video, I took a deep dive into the Arduino Nano ESP32 and compared it with other available boards in the market. Despite its seemingly high cost as compared to the options on AliExpress, its overall quality, fantastic documentation, and the fact that it fits neatly into the Arduino ecosystem makes it a good buy, especially if you've already invested in the Arduino Nano and its shields. The board has a few interesting peculiarity, including the use of a NORA-W106 module, a switch mode step-down converter for power, and an RGB LED. However, I was disappointed to find out... 29 October 2025
A Lot of Hot Air - Soldering ESP32-S3 Boards In this video, I test out the new hot air rework station I just got to solder my Mini esp32 S3 boards. I dissect the hot air gun, encountering an Australian plug and a couple of interesting quirks inside the control PCB. I attempt to understand the circuit, welcome your thoughts on the build quality, and then solder on a new, hopefully safer, UK-compliant plug. Post-assembly, I apply way too much solder paste thanks to these tricky solder syringes, before setting the station to 300 degrees C for some hands-on rework. After some trials, I successfully fix some solder bridges... 29 October 2025
Lovely High Res E-Paper Display Just when we thought we'd done with our mailbag, some exciting new stuff tips up. This time, we've got a soldering kit, a fun-looking Dash, and extra bonus, an ink plate 10, which is a cool e-paper display from Soldered. We've unboxed it, pulling out a board with an esp32 module, an SD card, and a battery connector. One of the major selling points is its open-source nature, you can download all the schematics from GitHub, and for those inclined, learn about how to build pcbs. Also showcased a Simon Says game soldering kit, despite my modest soldering skills (we... 29 October 2025
Easy S3 PCB and Schematic - it’s really simple. In this video, I explore the functions of my newly arrived little boards - essentially a PCB that an esp32 S3 room module can be connected to. I put the board's voltage regulator, battery charger, and a 3 watt class D amplifier to the test, and damn, they work perfectly! I even use breadboards, connecting them together to facilitate a wider workspace. I gave the pcbs a spin, conducting sanity checks to ensure full functionality. With a successful battery charge and impressive voltage measurements, my PCB's are up to the challenge. I also dabble in some circuit jargon, explaining schematics,... 29 October 2025
Lots of Stuff - And a NEW PCB! It's a rare mailbag video. In today's episode, I'm unboxing some goodies from PCB way - my super tiny esp32 breakout boards, which I'm planning to use to recreate a mini TV complete with speakers and a display. Also received some convenient adapter boards for easier testing. Excited to explore a new Arduino Nano esp32 based on a different, tinier module, and contrasting it with other products like the Tiny Pico. Also up for testing is a new mini wear electronic load compared to my old one, and an ATX power adapter for more USB ports. I'll be testing power banks, playing with inexpensive yellow... 29 October 2025

Another Street Battery Salvage In this video, I plucked a battery from a Honey Melon street crystal, ending up with another 500-milliamp hour battery to add to my growing collection. After checking the connection, I added a protective PCB and tested the battery - a reasonable 3.5 volts at a flat level. Following the safe soldering of wires and wrapping it up, I hooked the revamped battery to my charger. It showed promising results, charging quickly at one amp with voltage visibly on rise. After a full recharge, I performed a load test which unfortunately gave a disappointing 311 milliamp hour. It falls short... 29 October 2025
