Miscellaneous Electronics: Repair ultrasonic jewelry cleaner that just quit working

Tue, 28 Apr 2026 18:33:27 -0700

I have an old international silver company ultrasonic jewelry cleaner. I left on a little too long and it quit working. It's got a small simple copper motor with wires to an on/off switch and plug in and that's basically it with motor being a attached to flat metal piece. Nothing looks like like it was fried or burned out.

Miscellaneous Electronics: Damaged video surveillance system electronic board

Sat, 27 Dec 2025 23:02:54 -0700

I have this card that the technician replaced because it wasn't working. I want to test it using a multimeter (tester) and maybe try to repair it.

Update:

1) I checked continuity between +VCC and the first DD1 pin: it sounds;

2) I checked in diode mode between the two DD1 pins: I read 0.739;

3) capacitor resistance (ohms): 11.39;

Does anyone have schematic or info on fixing a Milwaukee Power Plus universal tool battery charger 9.6-18 volt? Model (cat no) is 48-59-0245. Any version of 48-59 will help. I’d rather fix it then go E-baying else I update! Two views, same board. Fuse is good, no caps are expanded.

BTW, I have two of em shot. The company is classic mute on the subject.

Ember Mug: How to change the battery in an Ember Mug

Tue, 11 Nov 2025 12:59:33 -0700

Ember’s (ember.com) original 10oz. mug is awesome! When I first got it it kept my drink hot for so long.

Now, a few years later, the battery dies after just 10–20 minutes. Unfortunately, the company does not offer a battery replacement service for the built-in rechargeable battery.

Has anyone successfully replaced the battery in an Ember mug? How did you do it? Where did you get a replacement from?

Miscellaneous Electronics: How to adjust a Franz LM-4 Electric Metronome?

Sun, 12 Oct 2025 13:58:26 -0700

I have a Franz LM-4 electric Metronome. I don't think the company repairs them anymore. Yes, there was something wrong, since my wife couldn't adjust the beats per second. I opened it up and found that the center screw needed to be tightened to the adjustment shaft - BUT at what position of the shaft?

While I had it open, the copper strip with an ~90 degree bend in it got loose and fell out. Don't know what it does or where it should be inside.

There are 2 metal screws that are probably supposed to be used for speed adjustment, but there must be some procedure to follow & I don't know what it is. Any help out there? Any former Franz technicians able to help?

Thanks, George

Miscellaneous Electronics: any trick to unsolder capacitors and other components from older board

Sun, 21 Sep 2025 10:19:51 -0700

Capacitors tend to be a very common component that fail. i have several old boards of various devices that have lots of them, but my solder iron with temp variable cant seem to soften and melt the solder adequately. in some of my efforts, the component got damaged by the heat and the solder was intact.

Is there a trick ? or old components are really difficult to salvage?

Thank you, André

Marco UP Series Electric Pump: Can UP3/E function on slow speed with SCS?

Tue, 09 Sep 2025 13:29:40 -0700

I have installed a Speed Control System together with my UP3/E pump. Normal speed, pump is working perfect. When I select slow speed, the pump is pumping slowly for a while until it stops completely and it will not pump again until I press reset button. LED is steady red as from the moment I select low speed. When pumping the red and blue led blinks alternatively. When I select the high speed again, the pump is working perfect again. My question: Does someone recognize what I wrote down? Is the SCS compatible with the UP3/E or is it maybe not?
