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.

Hrmm, I forgot you can just print these kinds of things out. Will help when assembling the new NES power/AV board.

This is kind of fun. Using an infrared receiver module (TSOP38238) to display the signals produced by a Blu-Ray player remote control on an oscilloscope. The signals are active-low and pulse-width modulated.
#electronics #oscilloscope

A TV/Blu-Ray player remote control pointed at a simple circuit on a proto-board. When buttons are pressed on the remote, the oscilloscope in the background displays pulse-width modulated patterns. Next to the remote is a datasheet for the IR receiver module on the proto-board.

Okay, had to make a second order of components because we're kinda off the script for hooking up the NESRGB on the NESessity board. Grabbed a 7 pin header for the P1 controller so I can use the controller to change the RGB palette in use as I don't want to use a mechanical switch. Also, I really want to ensure I can remove the NESRGB without desoldering anything.
Also, it's recommended to use a second 5V linear voltage regulator, but I'm going to skip it. The reason it's recommended is that the OG NES frontloader 5V voltage regulator will overheat due to the small heatsink size. On this build, I'm pretty sure the regulator is more than sufficient to dissipate the extra heat...lol

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. 🙄
