Re: Bluetooth DC Control.

In a car it is often used to link a mobile phone to allow hands free operation via the cars inbuilt radio and speaker system. You keep the phone in your pocket/handbag/briefcase etc and make or receive calls from the cars display screen. I've only recently bought a car with Bluetooth in it and it wo...

Re: Bluetooth DC Control.

I'm a bit lost with understanding what blue tooth actually is. Apparently phones have them, but when I tried all I ever had was "Unable to connect" or "No device found to pair with" etc. Never found out what it does except that I need two Bluetooth devices to make it work? Seems...

Re: HST - chips and sound

That's certainly a plan, although powering two speakers in parallel requires that they each be of double the impedance of the single speaker the decoder is designed to drive, to avoid risk of overloading the audio amp. Wire the speakers in series, this will double the resistance/impedance (assuming...

Re: checking track with multimeter

If you have a controller connected to the bus or the track, it might look like a short circuit on the track, depending on the controller and the way it is set. If the controller has a reversing switch with a Forward-Off-Reverse action it should (usually) be open circuit in the "Off" positi...

Re: Self adhesive numbers

I agree with Timbersurf, Dymo machine is very useful for all sorts of things around the house/workshop/train layout. Search on the net for replacement tape cartridges - they can be much, much cheaper than buying from shops. My last one only cost me £2.95 for a genuine 9mm X 8 metre black on white on...

Re: Drs class 57 cutting out DCC

As I said, not likely to be a short circuit, more likely a poor connection.

A short circuit is an unwanted excessive current flow, a poor connection causes a lack of wanted current flow.

Re: Drs class 57 cutting out DCC

Could be a loose connection. Fishplates, power connectors or dirty points could all be at fault. A short circuit would usually cause the Elite to shut down unless it was an exceptionally brief short circuit.

Also make sure the wheels and pickups are clean.

Re: how to make a 'pickup' wagon

There is some sort of reaction between lead shot and PVA that causes swelling after a period of time. If the mixture is in a confined space it can cause the container, for example a model loco battery box, to split.

Whether sheet lead is affected by PVA or not, I don't know.

Re: Hatford Junction Loft Layout

You can stretch a length of string from one end to the other and then hang a line level (a small spirit level) on the string. Example of a line level. https://tinyurl.com/yawjdsp8
Stabila isn't the cheapest brand but they make good quality levels.

Reverse the motor connections if you are dc.
If you are DCC you can alter CV 29 to reverse loco direction.

Re: Packed away locomotives

A good clean to remove any old oil and grease which may have dried out and hardened, particularly around the motor, gears and axles and then re- lubricate with suitable oils and/or grease designed for use on models. DO NOT use general purpose oils such as 3 in 1 oil or WD40 which are not suitable an...

Re: The wonderfull world of HO couplers

@ Tom@crewe

Because a magnet can't push a plain steel or iron object, it can only attract it. If the paper clip/staple was sufficiently magnetised then there would be a pushing action (repulsion) if the clip and the magnet were at opposite polarities.

Re: Soldering iron cleaning

I agree with Flashbang, it's normal for the element to be discoloured when the soldering iron has been used for a while.
