Implement a version with a temperature compensated clock such as DS3231.

~The DS3231 does not have SQW other than 32kHz. We might need a frequency divider circuit such as this one that uses a 555 and two 4013. In our version, we might need three 4013 to produce a 4kHz signal from the 32kHz SQW.~ The DS3231 does actually have a SQW output at 1Hz, 1.024kHz, 4.096kHz and 8.192kHz, but I leave the link to the frequency divider for further reference...
