Re: dcc digital

You might be better supporting the Wago by the wires going in near to the Wago using these; https://www.screwfix.com/p/cable-tie-base-natural-20-x-19mm-100-pack/36085 With a cable tie, just make sure the surface is sealed otherwise the adhesive pad may not stick well. Alternatively, these and cable ...

Re: Adjustable multi angle vice.

Aldi recently had some hobby vices available, the suction one is useless go for the edge clamp version. I have the latter and it’s been OK but then I never put it under strain really having a Record engineers vice for any robust work.

Re: Mimic board fixing.

The first thing I would do with either board is seal them particularly the MDF which tends to have a “dusty” surface which will take PVA but most other adhesives will have a poor bond. A coat of varnish will do or you can use PVA as a sealer. The laminated back of your mimic diagram will not produce...

Re: dcc digital

Hi Bob You mentioned your layout was a DC layout originally with a bus system, what you did not say is what the bus wire specification is. Too thin a bus will on a large layout introduce voltage drops which might explain the stuttering. Since it was a DC layout I assume you had switched sections if ...

Re: wiring LED

For safety sake I would still work on 12V, by ensuring you have adequate current limiting at 12V will also cover all other voltages. If you set your variable PSU at a lower voltage and calculate your current limiting resister at that voltage, there is always the potential to accidentally turn up the...

Re: wiring LED

Starting with your next to last question, it does not matter which leg anode or cathode the current limiting resistor goes. It seems you have a gantry with six two aspect signals and I take it that only six LEDs will be lit at any time be they red or green. Assuming you intend to run the LEDs @ 10mA...

Re: Three-leg common-anode leds in series ?????

Firstly, am I reading it right that you want all the red LEDs on the signals and mimic board to emit light together and likewise for the green? Bicolour two pin LEDs are simply two diodes reverse biased in one package therefore the current one way will switch on one and reversing the current switche...

Re: Multi pin connector plugs

If you have a reasonably sized wallet :o then the Jones plugs, sockets and covers (covers are called "Hoods") are possibly the Bees Knees of multi pin connectors. They are available in various pin configurations with 20 pin the largest . Example... https://www.mouser.co.uk/Search/Refine?Ntk=P_MarCo...

Re: Multi pin connector plugs

The use of multi pin connectors was discussed recently in this thread.
