    Another use for theseā€¦ they work well with the MQ-4 Methane sensor if you leave out the supplied battery and hook up to a 5 volt source instead. The alarm will go off for a few seconds until the sensor’s heater warms up, but new firmware could fix that.

    That,s correct. The black wire is the OPPOSITE side from ground. I made this elementary mistake and, though it took a while to debug, fortunately no harm was done.

No public wish lists :(
