Two fettles combined with upcycling today.
Firstly a motorised valve on the central heating system had the gear jumping. Repaired with the motor and gear assembly from an older valve. I don't know exactly where the older one came from, but I guess it was one that was replaced when heating was changed to valves on each radiator. I may have to change the whole valve operator soon as the rack was somewhat worn.
Secondly, a bluetooth speaker had stopped charging, but otherwise worked fine. It turned out to be a failed charging IC. I could have obtained one of those if I was prepared to wait a week or two, but instead I cut the Li-Ion charger section out of an old circuit board, and soldered wires from that to where the failed charging IC had been.
Give the cost of bluetooth speakers, while fixing it gives me a sense of satisfaction, it's not really worth my time fixing stuff that cheap. Repairing the motorised valve makes much better financial sense as they are expensive, and the valve operator can be changed while leaving the valve body, and the water, in place.
