I've started a rough inventory of electronic parts which can be used for music or other projects. Among some of the ICs/things I plan to bring:
- (3) SN76477 complex sound generator ICs
- (4) 74LS47 BCD to 7-segment decoder
- (3) 4066 quad analog switch
- 555 timers
- (1) Duemilanove Arduino and USB cable
- (2) photocells
- (4) 0.41" LED displays, common cathode
- (3) Red momentary pushbutton switches
- (2) LM741V op amps
- (4) LM741CN op amps
- (several) 1N914 diodes
- 7805 5V voltage regulator
- (several) general purpose transistors (2N3904, 2N3906, 2N2222)
- (several) low power Schottky and CMOS logic ICs
- (2) RS-232 sockets
- (2) 4017 decade counters
- telephone pickup coil (suction cup)
- (several) test clips with leads
- (several) small 8 ohm speakers
- (1) cable with mini stereo plugs on each end
- large breadboard
- (several) red LEDs
- (1) crystal microphone
- assortment of resistors and capacitors
- resistor substitution box
- (3) 9V battery clips
- tools, multimeter, soldering iron
I have a few more useful components such as 4060 ripple carry binary counters, TLC548 analog to digital converters, VN10KM and VN67AF VMOS power transistors, etc., but probably won't bring to this event as we'll probably not have enough time for the semi-complicated designs these would require.
I will also be bringing my collection of Engineer's Mini Notebooks from Forrest M. Mims. These have a lot of fabulous useful, fun, and instructive circuits. The titles I have are:
"Basic Semiconductor Circuits", "Communications Projects", "Op Amp IC Circuits", "Optoelectronics Circuits", "Science Projects", "555 Timer IC Circuits", "Formulas, Tables and Basic Circuits", "Digital Logic Circuits", and "Schematic Symbols, Device Packages, Design and Testing".
I'm willing to share the above for experimentation purposes while at the Music/Noise Night event.
Things that I'd ask others to bring to the event or locate at the Hack Factory, as far as electronic devices are concerned, would be:
- laptop computer (Windows) to share for Internet research, Arduino programming, midi playing
- benchtop variable power supply
- Arduino programming knowledge
- good potentiometers (rotary and slider) and rotary switches (mine are old and likely noisy)
- good set of resistors and capacitors with common values
- computer speakers
- incandescent bulbs or LEDs
- RS-232 plugs
- discrete mini stereo jacks, plugs, plug-to-plug cables
- interesting I/O components
- solenoids or magnet wire/parts to make some
I have some plans for other music/noise machines which I'd like to explore, involving more "macro" devices such as door bells, chimes, buzzers, pipes, and the like. If anyone else is actually bringing parts for such machines I'll also bring along some of my devices.
Also, if two or more people besides myself would be interested in hearing some midi performances/emulations on our kick-ass Hack Factory speakers, I'll try to find some time to put some files on a USB drive and run a demonstration. If there's little interest in this, I won't bother.
Maybe people have created other electronic pieces for computer/MP3 players too? If we aren't able to get live performers, maybe some attendees can show off their self-made tunes.
Kudos to Pat and Paul for their efforts on this event! Way to go, guys!
