Both variants of the hardware have now been completed and tested on a breadboard. The code which drives all of this stuff is also pretty much ready to go.So it is all off to JLCPCB to get it manufactured. The down side is that it is the start of Chinese...
While I am waiting for the boards to arrive, the time could be spent explaining the idea behind a separate programmer/debug board. As mentioned in a previous post, there is no way of programming the microcontroller while it is installed on the...
Currently finishing out the design phase of the robot, along with acquiring/building all of the parts. Done-Tested PICO board controlling a motor and a servo Printed main chassis and it failed Redesigned main chassisAdded LoRa COM module...
A bit 'o BackgroundEver since I got to visit a "Riding Railway" somewhere in Western, MA (US), I've always wanted to have a backyard railway that:I could rideHad some sort of purpose (moving firewood, rocks, etc)I've been interested in trains my whole...
I was think that I need get my hands on a a caliper first and disassemble it. To be honest I did not get any super interesting information out of that. I just ruined perfectly good caliper. The t-scale PCB is 0.5mm thick and has copper only on one side...
From the image above you can see the front, the back and the t-scale for my caliper. Bellow I will list a few things I considered while making this design. I chose the STM32F103 used in the blue pill because it is capable, cheap and schematic is...
Hello all, I got the first board assembled! Everything seems to come together really nicely. I am missing one differential driver, but I will get another one soon. Let the coding begin! With a display it looks even better!

I've been busy working on the PCB and routing on the computer, but while I'm getting much quicker and better at it, I've ran myself into a corner. We're gonna need a bigger board... This project is one of odd anachronistic design choices, pulling in...

Every tile job now must feature a niche. It's just one of society's rules. Fabricating a custom niche out of waterproof foam board seems straightforward, and that's the way I would do it if I had more experience with this. Instead, I've decided to go...
When I started this project I first made several prototypes to test all the features of the LPC1756. The first prototype was to make sure I could power up the LPC1756 and connect using JTAG and SWD.After the first basic prototype I made a small...
