I have a bunch of 283s and I've just rigged up an external 6v battery pack (with a sealed lead acid / SLA) battery. Works great. I have a few spare sensors and I'm wondering if it would be worth it to just solder in a resistor instead of a pot to give a defined power fraction. Any idea what resistance 1/4 power and 1/8 power would be? I don't need full vari-power, and a small resistor should fit inside the sensor module, which would be more discreet than this (admittedly very nice) hack.
