1. I really liked Margaret Sohn’s project. It seemed like a simple concept at first, but then the lights changed colors and I really liked that addition. I think this project was really fun to make and write a song for. Another one I liked was by Ethan Bailey, who created a little machine that played the glockenspiel when you would sing into microphone while pressing a button. The pitch you sing would be the pitch played on the instrument. It seemed really funny and a creative idea, but also looked like it was a little difficult to do. The last one that I really liked was by Jordan Bombi who created a pair of gloves that controlled sounds. This is by far my favorite, the concept and execution are just super cool and a little creepy. I would love to see a performance with these.
2. I loved this one, where you would touch a plant and it would “sing”. It uses the concept that when 2 conductive objects touch the capacitance between the objects changes, then it converts the capacitance into sound. One non-music project that was cool was this one, which buzzes when you are less than 6 feet away from humans which is really funny and I think handy for the times.
3. Digital, digital, digital
4. The programming I’ve done is at NYU, one Intro class that used python, and an AI class that also used python.

2. There’s a cool musical horn circuit that combines two 555 timers IC’s and it creates astable multivibrators.

1a. I love the T-Rex replicator tape echo pedal, not only for the really cool design but for how clear and beautiful the tape delay sounds. I also really liked the JAM Retrovibe pedal that gives a really cool vibrato to the sound and makes it feel like it’s from the 60’s. The last one that caught my eye was the Ghosty. Modulation pedal, which has a really cool lo-fi souring effect that makes the guitar just a little muted and also gives it a little vibrato.

1b. I feel like the smaller companies make pedals that not only produce cool effect, but also look really cool on the outside. The bigger companies are definitely super reliable and popular with a larger amount of people because they’re coming from sucha reputable source.

1c. I definitely think that the T-Rex replicator tape echo pedal is way different than anything I have seen. It incorporates an actual cassette tape in its design which makes it look really cool and gives the sound of the plugged in instrument a delay that can’t really be replicated.

2. This switch is used to switch between one “single” pathway.

3. The momentary button will stay pressed down and connect the circuit only when you press it and will disconnect the circuit when you let go, and the latching button will connect the circuit when you press it and let go, and you need to press it a second time to disconnect the circuit.

Lab 9 answers:

1. A
2. B
3. No
4. Distorted signal, clean signal
5. The exact averages of the 2 signals

Lab 8 Answers:

1. Integrator – triangle wave, comparator – square wave
2. Down, up
3. Positive, negative
4. Slower
5. Add more oscillators

Part 4) You increase the resistance so it cancels out a higher number of frequencies.

Part 5a) I think that I could make a revert guitar pedal. I personally don’t play guitar, but based off of the videos of previous projects I watched, I feel like I could make one and it would be fun to make.

Part 5b) I feel like building a monophonic synth would be more difficult but also very interesting to build.

Part 5c) I really love the Role Seaboard. I own one and it’s really cool to play around with, and I’m curious as to what’s inside making it work.

1. Adding a resistor and capacitor to this circuit is good because it protects the audio jack and audio system in your device from getting fried.
2. The differences between the inverting and non-inverting amplifiers on the oscilloscope is that the inverting amplifier shows a wave that’s inverted and that goes to 0 when turned all the way down on the potentiometer.

Using the oscilloscope:

• The input modes for bot channel 1 and 2: this receives the sound, can be set to ground so you don’t get anything through, just channel 1, just channel 2, or bot channel 1 and 2
• Volt/Div. knob: lets you zoom in and out across the y axis by changing how many volts are shown by each vertical line
• AC, GND, DC switch: let’s you switch to either Ac, Ground or DC audio
• Vertical Position knob: lets you move up and down in the vertical direction
• Time/Div. knob: lets you zoom in and out across the x axis by changing how much time is shown by each horizontal line
• Trig level knob: lets you stabilize the waveform, can do tis to just channel 1, just channel 2, both channels using the trigger source switch

The circuit components:

Part 1a) Before you touch the soldering iron to what you’re about to solder, you must to a few things. Turn it on to 350 degrees and wait for it to warm up in the holder. Make sure to have a wet sponge nearby to clean off you soldering iron with when it gets dirty, and clean it off before you start to use it.

Part 1b) Before you step away from the soldering iron, make sure it’s turned off and left in the holder. Make sure that your sponge is wet or damp for the next person. The wire should be left nearby and made neat for the next person.

Part 2a) You should always check where the red wire is plugged into on the multimeter because the position changes depending on what you are measuring.

Part 2b and Part 3)
