Miscellaneous Electronics: The drive is busy on

Tue, 17 Feb 2026 02:11:44 -0700

Hello,

Misschien kunnen jullie me helpen met de volgende vraag?

Ik heb een Yamaha Arranger Home Workstation Keyboard PSR-S 710 .

Regelmatig verschijnt het bericht: “The drive is busy on” wanneer ik een lied speel en op neem met de interne audio recorder op mijn keyboard PSR-s710. Dat is natuurlijk vervelend want dan moet ik telkens opnieuw beginnen.

Ik kan ook liedjes opnemen zonder problemen, maar ik weet nooit als ik begin te spelen om op te nemen op de audio recorder of dit bericht zal verschijnen of niet.

Ik weet ook niet hoeveel gigabytes de usb sticks mogen hebben voor het opnemen van de wave bestanden met de interne audiorecorder.

Graag uw antwoord om dit op te lossen.

Grtz,

gerald

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;

Miscellaneous Electronics: Milwaukee Tool Battery charger kaput

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
