Audio Spectrum Analyzer
The name audio spectrum analyzer is probably a bit too high trotting. A more befitting name would be funny looking graph display that changes with the music. But this was my second electronics project in 2018. It uses only through-hole components on a two-layer PCB.

Pi Boy Gaming Handheld
Features The software runs on a RPi 3b. The handheld features a 3.5′ 320×240 px TFT-LCD screen that I salvaged from a car rear view monitor but via the RPi’s onboard HDMI interface, it can also be connected to a larger monitor. On the front of the device, there are eleven buttons with four additional ones on the back. The backlight metal button on the side is the console’s power switch which is connected to the “PowerBoost 1000C” charge controller with an integrated 5.1 V boost converter from Adafruit.
