As said, yesterday and today I was and I am busy with cleanup of the electronics parts album that I got. I found many unused IC(see ) which I want to utilize in future projects and circuits. Another electronics part I found is the MMSZ5226B which is a 3.3V Zener diode designed for voltage regulation and protection in electronic circuits. Manufactured by companies like Vishay and Diodes Incorporated, it is commonly used in low-power applications to maintain a stable voltage reference.
