Step 5Solder Everything Together
Now that everything works on the breadboard, we're going to move it over to the chip.
Start with the power connector. Leave maybe ten centimeters of wire, just in case something goes wrong and you need to cut it off and reuse it. When you solder the ground and 9 V in place, it will help remind you where things are.
From here, I like "transplanting" the circuit: you have the breadboard next to the chip you're soldering onto, and slowly move components from the breadboard to the chip. This is one way to make sure you haven't forgotten anything. Make sure you don't forget that the orientation is different if your chip is upside-down and your breadboard is right-side-up!
Next, add the capacitors. I wrap the legs around the chip so it stays in place, then solder them on once they're where I want. One of the capacitors might have to stretch if it's going to ground, just make sure the leg doesn't touch anything it shouldn't.
Next, add any extra wires. If you're doing the independent oscillator design, you'll need wires for giving each gate its logic high.
Finally, add your resistors and FSRs. Resistors can be fit snugly under the chip, FSRs should be coming off the sides of the chip's pins.
Don't add the 1/8" connector yet, since you want to make sure the circuit works first. Solder some temporary connections (long wires) to the 1/8" connector.
