Re: Wireless Camera repair
I'd be concerned about the word "outdoor" in that sentence. Being exposed to the elements opens up at least a few cans of worms.? Including corrosion.? Or frozen (compromised) components.? Some of

Re: Wireless Camera repair
I just realized that the problem is likely just the wifi card that the antenna connects to. Problem is that it's likely proprietary and? not obtainable.

Re: Wireless Camera repair
I just opened it up with a Phillips head screwdriver and all the connections look ok. The antenna connection is on the frame or housing of the camera and looks in fine shape. It travels through the

Re: Batteries
Question about the Lithium AA cells - I know they use a little buck regulator to get the voltage down to 1.5V (nominal) but that also means that they are current-limited. Finding out the current limit

Re: Wireless Camera repair
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

Re: Wireless Camera repair
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

Re: Batteries
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

Re: Wireless Camera repair
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. :-) --

Re: Batteries
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

Re: Batteries
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

Re: Batteries
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

Re: Batteries
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

Re: Batteries
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

Re: Batteries
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

Re: Batteries
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

Re: Batteries
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:
