Here's a test board for something I have in the hopper - Because an empty canvas is a terrible thing to waste.
I've written more about how I did it (in Altium) here, but the important takeaway is the colour pallet I sampled:

Thanks for Liking and Following my #LED Matrix Display project!

Wow, thanks!

Glad you liked the project #Know your place, trace! - Oscilloscope vs. Magnet

Decided to make a series of similar projects, then later turn them all in a collection, or maybe an e-book called "Advanced measurement techniques with the Rigol DS1054Z oscilloscope" or something less boring.

This is the second in the series: #Know your place, trace! - Oscilloscope vs. Noise
It is about how to use the oscilloscope as a lock-in amplifier.

Like, share and subscribe, keep the Internet alive, wheeeee!

Thanks for the follow. I recently also made a tiny ESP32 design. With esp32-pico-d4, lte-m/nb-iot module, gps module, mcp73831 battery charger and solar input, all in 50x27mm. The ESP32 part was only 1/4th of the surface area.
