Tried that before, didn't work,, But i did find this out... Once the meter beeps right about the 14 min mark (warning turn off beep 3x) When it does this press the HOLD button 1x and and it'll stay on... Will also work after it cuts off, just press the HOLD button and it'll stay on. Hmmm..............

Press the Mode button to awaken the meter. To defeat this feature, follow the steps below. 1. With the meter OFF, press and hold the M (MO...

Hmmm.................. I wonder........... Try this: Just turn on the meter and start the egg timer at the same time. Do Not Connect The Probes To Anything. Now see what happens. If the meter shuts off, after 30 minutes. Then I'd say. The meter starts it's sleep timer when it doesn't sense anything...

I've also looked at the manual. There doesn't seem to be a way to shut off the "Sleep Mode" on this meter. :sad: Though..... I'd check to see if it really is shutting off sooner than the 30 minutes. Simple enough to have a egg timer ready and set for 30 minutes. Connect the meter to a volt...

Why not use a Baby Monitor? Plug the Baby Monitor Base unit into the circuit you want to check, with a radio nearby playing. Take the hand held receiver with you to the breaker box. You can listen to the receiver, as you toggle on and off breaker switches. When you no longer can hear the radio on th...

Happy Holidays everyone! One more year of COVID. But the current strain seems to be not as bad as the previous ones. :| Well, the weather has been nasty this past last year. Hail storm back in May, put holes in the roof, and thus had to get it repaired. {Ugh!} :( The Air Fryer's that I got from Men...

RFID Antenna...... What about a standard FM 88 MHz to 108 MHz Frequencies Antenna? I have a little GE Clock Radio that uses a antenna wire wrapped around the AC Power Cord for reception. This normally works okay, but I have to move the Power Cord around sometimes to get the station in better. Or Re...

Dacflyer.png If it looks okay, I'll go to spec and recalculate the resistors. Unless you want the fun :grin: That would be awsome.. I wish there was a cookbook on this LM3914/15/16 series of chips.. I could think of so many thngs to make, but i can't get enough understanding of this things, even fr...

Dacflyer, Your still looking, Huh? Well, like I said before. Get a bunch of Blue Rectangle LED's. A Protoboard, Wire, the Display Wiring Schematic. And make up the display yourself. Edit: I came across this video: https://www.youtube.com/watch?v=r_yobwaBWr0 Give it a look. The guy came up with a way...

High level signal into an external amp, aka speaker level like in car audio or even some subwoofer audio. Yeah, it's a pain to add more stuff onto the end run, but it seems to be the easiest way to gain access for analog solutions like we used to have. Anyway, years ago it was the blanking between ...
