Third Project: Creating a Sound Circuit
After reading the schematic, the necessary components were gathered. Unfortunately for me there were no 100K left to complete my circuit, so I improvised. I at first considered using a combination of a 15K and 82K resistors, but in the end I just used 120K resistors. I also redrew the schematic to make a more realistic representation of the terminals of the 555 timer.
After receiving a copper plate, I made an outline of where I wanted to manually etch the circuit paths.
Due to the dremel at the Interaction Station repeatedly losing power, I went to the woodshop and used a drill to etch the rest of the plate.
Soldering with the original 555 timer provide to be quite difficult, so I replaced it with a larger 555 timer that was easier to handle.
Final circuit - completely operational.
