Re: Charger circuit questions

Oh, I totally made this because I'm the type that like.. buys batteries in bulk for a lot of things and liked testing stuff. I wanted to see how good the top 5 AA's were on amazon before I purchased...

Re: Charger circuit questions

I could send you guys a simple Arduino load tester/schematic/spreadsheet I made a while back for testing batteries. Basically, it's basically just two voltage dividers and a current sense resistor....

Re: Why does my Uni-T multimeter not measure anything?

Ah... it's a shame a board that spacious doesn't have A) a 10a fuse and B) HRC fuses...

Ironically, that little gap where the trace was would probably fit one of those tiny 10a hrc axial lead...

Re: Why does my Uni-T multimeter not measure anything?

STJ speaks wise words. lol

Also, I know that this situation is a bit different since you were testing the socket, but if you work commonly with mains stuff I would suggest making a light bulb...

Re: Charger circuit questions

AH, actually, DGW purched a lot of different obviously fake batteries like that one and did a full load test and such. Many of them came out closer to 500mAh than 5000. He definitely knows that they...

Hmmm..... From what I could trace visually Sir, if you reversed the red and black wires, you would then need to touch the green wire to the NEGATIVE of the battery. Give that a shot. You may want to...

Re: Charger circuit questions

Wow, I was so wrong with what was on the circuit board... that was embarrassing. Ahahahaha There isn't even a second chip on the board! Just half-bridge rectification, some support components to...

Re: CCTV cameras: single PSU or individual PSUs ?

AH, yeah, honestly this whole thing just stemmed from the thought that you could do a pretty simple active/passive failover with a relay and a few support components. ^.^; I didn't even really have...

Re: CCTV cameras: single PSU or individual PSUs ?

Okay! I drew up the schematic in everycircuit to try to explain this a little bit better. there are some limitations to the layout capabilities of everycircuit so it's a bit of a mess. ...

Re: CCTV cameras: single PSU or individual PSUs ?

That would depend on what the latch circuit is. if you're talking about the simple circuit with the relay then just turning on the primary PSU would click the relay on. Since the relay on. If the...

Re: CCTV cameras: single PSU or individual PSUs ?

Ah, I will do so later for sure.

In the simple circuit, I would be relying on something like this circuit (low-tech 12v battery undervoltage protection). ...

Re: CCTV cameras: single PSU or individual PSUs ?

Hmm... You know, you could make a super simple failover for a 12v bus by using a relay. So like, you could get 2 of those meanwell supplies and then have the psu's sitting in an active/passive setup....

Re: Ubiquiti Nano Loco M5 5ghz, does not turn on, internal buzz

I would probably take my meter and check how many ohms are reading on either side of some of the power rail capacitors. You might have a short that is pulling something to ground. For instance, you...

Re: Feed-thru 8P8C's
