a CR1220 coin cell holder to keep the RTC running and allow warm starts and a tiny bright red LED

For instance a 10 dB + 30dB attenuators connected in series will give you 40dB total attenuation

SoftPot Membrane Potentiometer - 50mm Shipping:1 day then connect one of theThese are very thin variable potentiometers. By pressing down on various parts of the strip, the resistance linearly changes from 100Ohms to 10,000Ohms allowing the user to very accurately calculate the relative position on the strip. Can be used as an accurate positional indicator for CNC head positioning, variable user input (volume level input for example), straight user input (multiple button areas translate to given resistance levels), and many
