rarely

I have a samsung galaxy s22 phone with android. I had a wear OS device that I paired with the phone but cannot now remember the passcode. Sometime around the time I paired my wear OS device and maybe due to an app I had installed on that device, my android now beeps on the hour, every hour, all hours of the day and night. It is a little annoying and it causes me to turn off my notifications and notification bell so that I am not constantly interrupted. Today it started beeping twice on the hour. I fear I may need to do a factory reset on the phone because i cannot stop this beeping. I have roughly 700 apps on my phone but few have notifications enabled. When I get a beep on the hour there is no notification, just the beep. My alarms are all disabled.

Is there a way I can stop this without wiping everything on my phone and starting from scratch with a factory reset? I have factory reset my wearos device and re-paired it with my phone but the hourly beeps continue.

Serious question from a beginner in electronics. For reasons I do not fully understand, I have become fixated on the idea of collecting small amounts of electricity from “interesting” sources. I don’t mean “free energy”, instead, I mean things like extracting a few mV from being so close to a AM radio tower using two tuned loop antennas in phase with each other, or getting a few mV from the rain’s kinetic energy with PTFE and using two electrodes which are shorted when a drop of rain hits it. In short, I’ve done small experiments to confirm that I can get a few mV and enough to get me excited but not much more. I know I’m not going to get much power out of this, but I’ve been able to charge a NiMH battery a few mV by being a quarter mile from an AM radio station with my antenna setup. It would be fascinating to me if I could store these small charges in something like a 5V USB power brick eventually.

The smarter idea would be for me to harvest energy with the sun or from the wind or a stream. I’m tinkering with this as well, but larger amounts of electricity scare me for right now. I guess I’ve seen enough experimental sources of harvesting electricity and I’ve gotten the itch to invent, which is a dangerous itch for a newbie like me to have.

The best advice I’ve seen online (ok, it was ChatGPT) is that it’s just not worth it to work with such small amounts of electricity, because the equipment required is too expensive and sophisticated (e.g, devices to read the charge of a capacitor without discharging it) to make anything that’s efficient enough to be worthwhile. Would you agree? Do you know of some other fascinating source of gathering electricity that I should also waste lots of time on?

I just have all these electronic components and magnets and when I move them together the numbers on multimeter get bigger. it’s neat.
