Re: Craftsman Multimeter
Thanks but there's something wrong with that ad. It actually leads to a Klein meter. No joy.

Craftsman Multimeter
Looking for the operating manual for an old autoranging multimeter:
Craftsman Autoranging Multimeter 82028
Googled, but couldn't find it. It's maybe 15-18 years old.
TIA!

Re: A grounding 'feel good'
Have you tested it? Maybe the plastic is conductive!

No doubt made in a country where looks trumps function.

Probably saw some of these transformerless AC-to-DC circuits:

Re: Need a Schematic for: NEWCOMB Model: B-100A AM Radio
If that is a 6V6 audio output tube, a 5,000:3.2 ohm output transformer will be fine.
Break out a drill to remove the spot welds, and insert screws/nuts to mount the new transformer.

Re: Battery powered mower issue Solaris Brand.
Monitor the drive to the motor, and see if the drive signal is varying?

Re: Grid-Tied AC microinverter
Yes, definitely an off-grid situation. If you're wondering why not use an off-the-shelf Walmart or Harbor Freight inverter, the solar panels I have output 30-40 volts DC, and those inverters do not handle those voltages. A microinverter, however, is made for that input range. Good ideas folks, and w...

Re: A Slightly Uncommon Monitor Cleaning Problem
I'd be very cautious with any acetone anywhere near a plastic screen.
Never tried it in light doses, but unless you have the likes of lard or vaseline on the screen, avoid acetone.

Grid-Tied AC microinverter
These devices have a unique feature- they must first see 120 VAC, 60 Hz on their output, before they switch on and contribute power to that AC line. The purpose is to disable the output of a solar module in the event the grid goes down. If the inverter did not shut down, it would be supplying AC to ...

Re: need help looking for a DC input led power supply (12-24
Why not build yourself a rechargeable Li-Ion battery pack? Size it to whatever your voltage/current needs may be.
18650 size Li-Ion cells are all over ebay for cheap.

Re: Copper Theft
It does make perfect sense, especially for overhead lines, aluminum being lighter. Maybe Alcoa/Reynolds don't have the same political power with the utilities that the existing copper suppliers have.
