Is the screw on connector mounted on the PCB or is there a jumper? Most cameras I've worked with have a short, 5" or so, jumper with a press on RF connector on the PCB. A few have the SMA directly on

I will see if I can get into the camera and post pics of what I find or see inside. I probably have the correct tools to get into it as I have some gun tool kits that have an assortment of bits along

You don't need to cut anything open. Just grab one corner of the sheet metal where it joins with a pair of needle nosed pliers, and twist. Keep going like that and eventually you peel all of the

Harbor Freight has a set of bits like that too. They've pretty much covered my needs when I encounter some of that weird stuff. I try not to do business with amazon to the extent possible. :-) --

One more battery detail: Pagers (beepers) used N-cells and later AA-cels. Mercury cells were popular with the much longer life. I collected dead cells and recovered the mercury that I then

Nobody but engineers and chemists called them by their proper name. Leclanché cells were the first practical "dry cell." They started out dry but the electrolyte was replaced with magnesium dioxide

It appears to me that the alkaline batteries have gotten worse. Presumably thinner shell to save money and increased performance. It also appears that the free carbon-zinc batteries from China leak

If rumors are to be believed (I know, there's a major problem with that), then some brands are considerably better than others in this respect. I have been warned never to buy name-brand "X" because

I've heard of "wet cells" versus "dry cells".? That Wikipedia article suggests that Leclanche cells would be called "wet cells" and were *not* the same as the normal "dry cells" that were commonly

Really?? So what you're saying is that all the carbon/zinc batteries that everyone around here (USA) used for decades before Alkalines came out, were actually Leclanche cells.? Then why didn't they

My wife has something that uses one.? I think it goes with her tablet.? From about 5 years ago. I got replacement AAAA cells at either CVS or the local grocery store.? They were relatively cheap

Nice! I've never met a flashlight I didn't fall in love with. I have some Soviet flashlights, varnished cardboard tubes and reflector and the glass has rough edges like it was snipped from window

Noone has mentioned the flat 4.5 V flashlight battery. It was very common when I was growing up in Sweden. The size was 65 x 60 x 23mm and fit nicely in a pocket. See:

If you can open the case, many security devices use "odd" screws, you might find the antenna connector popped loose. Most of these connectors are press fit and not 'real' microwave cables. Amazon has

I have a Lorex wireless security system that uses it's own receiver for the outdoor wireless cameras. I just recently had another camera appear to fail but I can "pair" it with the receiver if I am

There were 4 "F" cells inside the lantern battery case. You can still buy them (at least as of 2023) but almost all had 4 "D" cells with a spacer at the bottom. I used the lantern batteries with screw

I must have made a typo I meant *Leclanché cell.* **https://en.wikipedia.org/wiki/Leclanch%C3%A9_cell** **Up until alkaline cells replaced the *Leclanché, the *Leclanché was the standard "D" "C"

My father wore a hearing air starting in the late 30's. I recall him having a 45 volt and 1.5 volt battery that he would put in his right rear pocket. These powered the vacuum tubes in the aid. When
