Thermistor circuit
Thermistor circuit with CD-ROM audio connector wiring (MPC-2 connector).
For $5.60 US you can order three of these boards from OSH Park. That includes free shipping within the USA. Note that OSH Park always sells in units of three. The URL is

The sole required component (beyond the 100K NTC thermistor itself) is one 4.7K resistor which you can likely buy at a Radio Shack (Digikey S4.7KCACT-ND). The optional components are a 0.1 uF capacitor (Digikey 339-4151-ND), a MPC-2 connector (CD-ROM audio; Molex 0705550038; Digikey WM4177-ND), and a two position screw down terminal (Phoenix 1729128; Digikey 277-1247-ND).
