some workshop_notes
day 1 [wed.20051026]
- physical computing > http://www.tigoe.net/pcomp/index.shtml
basic electronics
- circuit diagrams
- conductors/insulators/resistors
- two formulas to remember “V=IR” and “P=VI”
- Voltage (V) measured in Volts
- Current (I) measured in Amps
- Resistance (R) measured in Ohms
- avoid short circuits
- sensors → transducers
- directional/non-directional components (in general, directional components are marked (eg. +/-, lines, etc))
- resistors (nd)
- variable resitors / thermistors / photoresistors /FSRs
- capacitors (can be n or nd)
- diodes /LEDs (d)
- switches
- quite versatile. anything which connects/disconnects 2 conductors
- transistors / relays
- switching devices
- piezoelectric
- serial (in series) & parallel circuits
- using breadboards → [ ]
- using a multimeter → [ ]
- using thermochromic ink to demonstrate resistance
- soft circuits
- electrically identical to breadboard circuits
- use traditional techniques for working with fabrics (cut,sew,stick)
- rely on conductive expoxy rather than soldering components
- silver organza → woven silver/silk in warp/weft
- conductive threads → often uses threads, rather than wires. 2 approaches, either non conductive core, wrapped with conductor; or threads saturated with metalic particles, then spun.
- silver/gold coated threads, conductive, low resistance, easily frayed
- bekaert > nylon coated with stainless steel, sturdier (can be used in sewing machine), higher resitance.
- bekaert > silvered
- various combinations, woven threads.
- see examples → [ ]
- gorex > resistive heating
- nitinol > SMA nickel/titanium, variable temp. for setting, flexible when cold
- conductive EM shielding materials > http://lessemf.com/
- color/colour changing/conductive textiles > http://xslabs.net/color-change
