Looks like it is using an Arduino clone as the main board.

I suppose if the overhead catenary is supported on gantries across the track the angle at which you view the scene may have quite an effect on what you can see. A bit like Venetian blinds the angle at which you look through them determines how much you can see.

At my last house because the central heating system had been altered at least three times by the previous owners and was a maze of imperial and metric pipework, the simplist thing to do was strip it all out and start again. I stripped it there was just a stub of pipe coming out the floor where the s...

I got the suction version sometime back but found out unless you had a glass or equally smooth surface it eventually came off and I was trying to secure it on what I thought was a smooth varnished desk top. Got the edge clamp version next time round and although it is not the most accurate in the se...

Apologies BNB you are absolutely right this is a classic case on my part of getting an idea rolling at the back of my head and managing to get 2+2=5 or should that be 3. :mrgreen: After your first post mentioning 2 diodes the classic full wave rectifier with a centre tapped common came to mind and I...

Could you power the signals with ac and then use the seep switch to change the polarity by using diodes. https://i.postimg.cc/k2y732Nd/ac-dc.jpg Er! No I think you have a slight misunderstanding of AC, a true AC supply does not have a positive and negative both terminals alternate according to a si...

Aye, thanks Richard, I assumed the Seep wouldn't be up to it on it's own so will look at the other options. Early days yet. Mind you, this does lead me onto what might be termed a fundamental question re signalling - with colour lighting, the nice pretty colours are only viewable along the "line of...

If you have SEEP PM 1 then you will not be able to reverse the current as the built in switch is merely a changeover switch. If you are using the PECO motors, I think you can rig up polarity switching using 2 PL-32 microswitches mounted on a PL-15 mounting plate, as far as I can remember the movemen...

Assuming these lamps have bulbs rather than LEDs 1. Connect one connection on all the bulbs together. 2. From the connection you have just made connect a wire to the 0V (-) connection on your PSU. 3. Connect the other connection on each lamp to one of the outside terminals on each switch. 4. Connect...
