Number Six of One's Electronics Projects

The big mystery make project, what is it, can you guess? Will it work when I'm finished? It's desktop sized, and fairly complex, in fact, it's the most complex thing I've tackled to date, and I'm worried about it. Building it involves Stepper motors, wires, gears, a microcontroller, computer interface, and lots of 3d printing and metalwork. This is a long one, so, give yourself some time.

So there have been no techie/DIY videos from me for a while, and the last one revolved around installing software. Why no tech videos? Why no DIY videos? Watch and see!

BN-880 GPS Module - Part III - Tying It All Together Wrapping up the breadboarding of an Arduino Uno, A GLCD Module and a BN-880 GPS/Compass Module. Here's a link to the wiring diagram and the code for this project: https://cat-walker.blogspot.com/2022/06/beitian-bn-880-gps-and-compass-module.html

BN-880 GPS Module - Part II - GLCD Module Carrying on with the BN-880 GPS module. This time, prepping a GLCD module for use. Hee is a link to the code and the wiring diagram: https://cat-walker.blogspot.com/2022/06/beitian-bn-880-gps-module-part-ii-lets.html

Heathkit HD 1416 Code Practice Oscillator. I take a trip down memory lane, engage in a bit of nostalgia, and scratch-build an old CPO. Video was recorded almost three years ago now.The circuit description is a little oversimplified (not by much) and the circuit animations are also a little oversimplified (and a touch out of sync with the audio) but I wanted this off of my hard drive after almost three years.

In my first (new) tech video in two years, I hook up a Beitian BN-880 GPS/Compass module to an Arduino Uno. This a short video, only a few minutes. TinyGPS++ Library is here: https://github.com/mikalhart/TinyGPSPlus Downloading this gives you a zip file with the example projects.

This is to be a continuation of the antenna analyzer project, and we do two other project boards as well.

Using Ferric Chloride to etch away the unwanted copper from our board. I can't emphasize this enough, this stuff is corrosive, if you use it, you do so at your own risk!

Soaking the board with the ironed-on pattern in warm water, then slowly rubbing the paper off.

Let's iron the PCB traces, in toner, onto the blank board.

This video contains part one of my antenna sweeper project, this is the breadboard stage, to make sure the LCD screen is going to work.Part two is a long way down the road :(
