    Testing a Boiler Thermistor

    It's not like thermostat. A thermistor changes resistance with temperature, it doesn't have contacts. If you can find the nominal resistance from documentation, you can check it with a suitable meter.

    RJ11 pinout

    If you disconnect the incoming analogue line from your existing master socket and connect the line from the router to 2 & 5 on an extension near the router it should work. Mine works fine that way. Or move the master socket to where the router is, BT won't know or care.

    RJ11 pinout

    Yes. Modern phones don't need a bell wire and bell wire can cause issues or speed reductions with adsl. Best disconnected at every socket.

    Strange Socket In Hospital

    Very unlikely each outlet on a twin pate would be on different circuits. I've seen plugs/sockets with "T" shaped earth pins used in hospitals for connecting medical equipment t deidcated/clean earth supply. You can still get them ...

    Fluoresent or LED

    My street was done about 8 months ago and the improvement in light coverage and quality over the old yellow sodium lamps is immense. In addition there is much less stray light both upwards and sideways. They did a one for one replacement of the existing lights, each one took about thirty...

    Mystery Wire Switched Fuse Spur to Blank

    If there is only a single cable connected to the FCU then just remove that too. Then you can remove the unused back box, fill and decorate over.

    Have you read the q&a on that offer. There's a severe restriction right at the bottom.

    Measuring resistance with Ohm's law does not work with sensors because? Does anyone with knowledge about alarms have an explanation

    What I was getting at is that all power sources have internal resistance and the available voltage will be split across the internal resistance and the load. This will be the case even if the load is just a simple resistance. For example, suppose you have a 10V supply and a 1000ohm (1k) load...

    Measuring resistance with Ohm's law does not work with sensors because? Does anyone with knowledge about alarms have an explanation

    How are you powering the circuit? The source impedance of the supply could be skewing the readings.. A diagram would be helpful

    New skool phone wiring

    What I did was to get OR to install the NTE 5 with the unfiltered faceplate, then I ran a normal phone extension from that upstairs to where I wanted the router, where I installed a NTE 5 with filtered faceplate to which I could connect both the router and a phone. For the dowstairs phone...

    What reasons for outdoor chrismtas led string lights not to work, even if electric signal detected?

    Those pens detect the presence of a voltage above a given level, not the flow of current.

    How many wires for phone VOIP

    Not these days. Very few, if any, modern phones require the "bell" wire to "ring".

    Home LAN access to a device...

    Not clear to me that there are any "incoming" connections. If the PI and the browser are on the same local subnet, then after the initial ARP query to determine the local MAC address of the Pi, no traffic goes through the routing function, only through the built-in wifi AP and switch. If the Pi...

    Broadband and telephones

    I was about to make that same point. When directly connected your laptop has a globally visible IP address and is open to port scans and all sorts of attacks.

    Excellent! That may not work for other ISPs though.
