BOARD
COMPONENTS
Miscellaneous:
1x piece of Veroboard (stripboard), sized 15x9, with traces cut in the
marked areas
1x SPST ON-ON toggle switch (literally any two-position switch will
work, but the SPST is the smallest)
1x 8-pin DIP (chip) socket (I recommend the “tooled” type, where each
pin has its own round hole)
Wire
Resistors:
3x 10K
1x 1M
1x 2M (two 1M resistors in series will work, a 2.2M will also likely
work)
1x 220 ohm
1x 2.2K (this is for the LED)
Capacitors:
4x 100nF (0.1uF)
2x 1uF film capacitors (non-electrolytic)
Potentiometers:
1x 10KA (logarithmic taper)
1x 25KB (linear taper)
1x 1MB (linear taper)
Semiconductors:
1x LM741 chip
