Built an RGB Bulbdial last week. The kit came together nicely. One problem. The Chronodot module furnished by Hackaday seems to have no effect whatever. Battery which came with Chronodot was on the decrepit side, measuring 2.66 (of nominal 3) volts. Put new one into module but no change. Is there a jumper unjumped? Or some other installation quirk I missed in the ream of instructions? When working, is the Chronodot supposed to read the last set time on the BulbDial, storing same for next power-up?
