Modified Schematic and Breadboard Time


I made a couple of modifications that worked for my Baby-10 sequencer project
The modified circuit was breadboarded and worked like a charm 👍
- I replaced the TL072 Op-Amp with an LM358 which resulted in a less noisy output signal.
- I replaced the 1uF electrolytic capacitor C1 for a 0.1 uF K63 film capacitor for better and well defined gliding voltage-range output.
Pcb and Silkscreen (made With DIY Layout Creator)


The bottom copper pcb and the silkscreen are both reversed and etching ready :)
Actually the only thing I can brag for is the actual PCB that I crafted myself as a personal learning tutorial on DIY Layout Creator

Etching


Tried to slightly reduce the etching surface for faster etching time
Final PCB

... and it worked !
