Re: Auto Signal Control: IR LED transmitter / Receiver Problems

Paul have you tried the obvious and tried the IR LED both ways. It could be just the angle of the photo but the small flat that appears on the bottom rim of 5mm LEDs indicating the leg nearest being the cathode is towards the positive side from what I can discern? Edit: The leg of the 220R resistor ...

Re: Brake van rear red light

Reed switches were only designed for low current signal level switching. Although in my time I have seen some quite hefty ones what is mainly available now are only suitable for low current. As Brian has said NO, NC & changeover are the most commonly available. The need for latching has somewhat dis...

Re: Brake van rear red light

Yes you can. I would rather use a coin cell either 2032 or 2025 both commonly available from supermarkets etc. Make sure they are Lithium 3V and not Alkaline(1.5V). Get a coin cell holder appropriate to whichever cell you have chosen, l would go for one that can be soldered to strip board. I would a...

Re: Auto Signal Control: IR LED transmitter / Receiver Problems

OK, slightly misread what you were trying to do, I thought you were triggering the circuit by a break the beam type of sensor rather than reflecting IR on the IR Rx. Having watched the video I would not have constructed the sensor circuit as EJ has done but would have rather I would have mounted all...

Re: Auto Signal Control: IR LED transmitter / Receiver Problems

Try using a non-reflective material as a IR barrier. IR can reflect off many surfaces you can often change channels on a TV by pointing the remote at a wall behind you if it is light enough. Your bit of tin foil might be reflecting IR all round and causing the sequence to re-start. I would suggest i...

Re: Solenoid Power Supply : plaited 3 wire

I cannot see induction being an issue with solenoid motors and I am a little unclear how the plaiting will save switch contacts, I presume they are talking about the BEMF spike you will get as the magnetic field in the solenoid coils collapses. Anyway, a quick method of plaiting individual wires is ...

Re: Digital n gauge query

DCC ready usually means it has a socket that will simply accept a plug in decoder. DCC fitted is the term used when the manufacturer has pre- fitted a decoder. Do take care to establish which type of socket is in the loco as there are several different versions, but as you are talking N-gauge it is ...

Re: What DCC Controler ?

I think you will find all DCC controllers can run 3 trains simultaneously it will be more a case of you being able to keep track of what is going on ('scuse the pun). As for your other question I am afraid you will probably get a lot of people claiming their particular controller is the best thing s...

Re: The great model railway challenge

Looks like there is going to be a second series, the voice over at the credits in heat 5 invited people to sign up for another series. I think heat 5 was the best so far with Aberdean MRC worthy winners. I also think it was the toughest challenge incorporating water real or fake was going to be hard...
