			This wiki page is still being worked on. What should we do next week?

			Ideas:

			* Re-visit the LM386 and make ourselves a nice line-level amplifier/speaker combo that'll run on batteries and provide us with a good source of 5v.

	~~== Onward ==~~		* Revisit the 74HC04 and work on filters some more

	~~At this point, you're going to know most of what I do. No more learning, only discovering...~~		* Ghetto ring modulation and pulse sync

			* Voltage control (?)

New page

== Overview ==

The Noisemaker Workshop will teach you how to build noise-making electrical devices from the ground up. We'll be mostly building our own gear, but we'll also borrow a couple tricks from the glitch/bender tradition.

This workshop series involves soldering, (ab)use of digital CMOS chips for analog ends, a smidgen of electronics knowledge (provided), and plenty of noise. You bring the musical sensibility (not required).

== Day 1: Getting Oscillating ==

This class focuses on the 74HC14 logic chip and how it can be used to make a square-wave oscillator. By using a light-dependent resistor in the feedback loop, you can control the pitch by waving your hands around.

== Day 2: Modulation ==

So you've got one oscillator. Great, now build another. Now have the second feed into the first. Fun.

In this class, we get around to Frequency Modulation, Ring Modulation, Gate/Sync, Pulse waveforms, and ghetto Amplitude Modulation. We'll also learn about the importance of buffering. LED's will blink rhythmically.

== Day 3: Sequencing, Clocking ==

Using a low-frequency as a clock source, we'll drive a counter which drives a multi-way switch. Point the switch at different resistors = different pitches = 8-step sequencer. Mayhem? Music?

== Day 4: Amplification and Filtration ==

Here we go a little bit analog. Using a 74hc04 chip as a buffer/amplifier, we start to get non-square waves. An amplifier with a capacitor in its feedback loop makes a nice lowpass filter. Here, we'll also do some real Amplitude Modulation.

Note: many of these resources require translating from old 4000-series CMOS into lower-voltage 74hc00 series chips:
* 40106 -> 74hc14 (Inverter with Schmitt trigger)
* 4051 -> 74hc4051 (8-channel switch)
* 4040 -> 74hc4040 (Binary Counter)
