My first self-designed printed circuit board (that works).
#electronics

A red printed circuit board populated with integrated circuits, resistors, and capacitors. The upper right corner reads "Lorenz Attractor" and the lower right corner reads "June 2025 Rev 2".

Here it is in action numerically solving the Lorenz Attractor differential equations.
#electronics

The printed circuit board from the previous post connected to a power supply and oscilloscope. On the scope is the famous Lorenz attractor butterfly.

I did some experiments measuring propagation delay in a simple chain of 3 digital inverters (NOT gates) (74LS04).
I'm honestly not sure my entry-level scope is fast enough to accurately measure this, but it's fun to try.
It's also interesting to watch the signals completely freak out when you change the input voltage too slowly, but I didn't make a screenshot of that.

Electronics lab bench with oscilloscope, signal generator, and power supply with leads connected to a small breadboard circuit.
Oscilloscope screenshot with four traces. Rising input voltage (yellow) and outputs of successive inverters (cyan, magenta, blue). Cursors measure the total propagation delay to be about 30ns.

Scored a 65W USB-C "Hama" charging block for €5 (down from €20) at "expert" #Germany. 🤓
I don't know about the brand, but the charger works fine with my devices. Crazy though the company website wants €60 for it. 🙄
