Somehow I was unable to save the file, so here is a substitute https://drive.google.com/file/d/1rsuT0AaQXD_cGVXSRHxi2pdLTecQDQ_M/view?usp=sharing (a file that exported) Here is a light switch using monostable 555 timer.

lab13 1.)Nick Royall has a really complicated sequencer, keyboard and drum. And it is even able to switch sound source. It can be played as a keyboard and used as 8 step sequencer. It can even change the light.  Paul Odenwaldt’s GrainCube is cool. It allows users to use gamecube controller to sample and createContinue reading “Lab 13”

Ground Control audio There isn’t much description about the company, except it develop one amp at a time. And the art on the pedal is really cool. Like: It is really cool. Like Amaterasu and Serpent, the harmonics sounds cool.  Dislike: god its expensive. A distortion pedal cost $170. And the lower end of distortionContinue reading “lab 11”

1)b 2)b 3)the two will not sound the same, because the two diodes will interfere with the output if connected, because the two diodes act as resistors, and make the volume way smaller than that. 4)clean signal, distorted signal 5)half clean signal half distorted

1) With the oscillator we’re studying the comparator outputs a _______(square) wave and the integrator outputs a _______ (square/triangle )wave. 2) With an integrator, if Vin is positive the output voltage ramps ______down (up/down). If Vin is negative the output voltage ramps _______up (up/down). 3) With a comparator, if the op amp’s + input isContinue reading “Week 8 Lab Report”

I think I could build a amplifier, some kind of gain that adds harmonic distortion a multi-band filter would take more work but fine? compressor. It’s a really helpful mixing tool, give my track fire. I would love to pay my respect by building one

DC Blockers: Resistors are inserted into the circuit to prevent large current, protecting the circuit. Capacitors prevents the flowing of DC, and allows AC. This protect the signal output Non-inverting amplifiers: to have a gain of two, meaning 1+r2/r1=2, r2 is equal to r1. when gain is one it means r2 is 0. when gainContinue reading “Lab Report #5”

power turns on -volt/div 0.5 both it is the scale of the display. 0.5 volt/div means one square represent 0.5 volt -position in the middle: it puts the display in the middle -mode dual it means showing both channel 1 and channel 2’s status -horizontal 0.5 adjust wavelengths narrowness i think ‘time’ knob do theContinue reading “Lab Report #4”
