Blimey End2 a busy weekend, it looks like it's been a most successful one too. Are the damaged moulds repairable at all ?

I'm not sure to be honest Dublo. Once I've tried to clean the crud off I'll have a better picture but as they are the flimsy moulds I don't hold out much hope.

Oh and on top of all that we also have a new kitten. :D
Thanks

Beware of it going to sleep on that patch of new grass you've just glued down.....

The new station master's cat, "Marley" (no relation to the singer) says hello. :D

Today I've been playing with an idea for a multi socket decoder tester. I need to buy the actual sockets but I have been trying to work out the wiring diagram for a piece of vero board. I then expanded the diagram to include being able to test the front and rear lights but I am not sure if it will work.
Can someone take a look at the diagram (below) and see if it would actually work please?
The 2 LEDs would have a 1KOHm resistor but would this need to be on the Blue (COMMON) leg or the Yellow / White leg?

I've just noticed a glaring error on the plan. One LED should connect between White and Blue not Yellow and White. :roll:
So there should be 2 LEDS, one LED connected to Yellow & Blue and one LED connected to White & Blue.
Pretend it's that way. :oops: :arrow: :lol:
Thanks

Can I just bump these last 2 questions as IF my design would work I'd like to buy the componants I need.

The 0-4-0 motor turned up today for my ECC 08 shunter so I have fitted it and run it in and also greased and oiled the loco, cleaned the wheels and painted the buffers black. I do have a couple of decoders that may fit the bill but I need to test them first, hopefully with my decoder tester once built and if it works. (see a previous post a couple of posts up for the design)

Linkaonline have finally posted the mould I ordered on the 28th :roll: so hopefully I should get that in the post by the weekend or the start of next week.
Also today I received Timbersurf's Linka windows so expect some test pieces soon. :D
Thanks

I will eventually need one myself, so I had a go at proving your diagram. The issue is that the 8 pin has a blue wire, but the 6 pin has no common pin for the LED's!. Apparently you connect them to black! So when using a 6 and 8 pin, the common would need to be switched to the appropriate colour.

OH...erm....yes...but
I only meant LED's for the 8 pin decoders. I wasn't aware you could get 6 pin decoders with lights so didn't include them in the design.
Probably something to do with me not knowing and no actual specific lighting wire on the 6 pin decoders.

The LED's (for 8 pin decoders with the associated wiring) was an afterthought of the design so no provision was made for any other decoders LED's, deeming it unnecessary. This circuit is mainly to test that a decoder works, as in motor function.
It will never have more than one decoder plugged in at a time.
As this is the case, looking at your design Timbersurf, would I really need a switch or could I just hard wire the black permanently?
OR
personally preferable, do away with the switch and the wiring for the 6 pin LED's completely, leaving the original design with LED's ONLY for the 8 pin socket with the full compliment of wiring and the 3 decoder sockets.

I know this way, I won't be able to test 6 pin lighting nor other decoder functions, but do many of us use 6 pin decoders in a lit loco?
I'd plump for an 8 pin in that case with the extra wire to make life easier.
Thanks

The easiest may be to wire for 8 pin, forget the switch and just wire the LED's to blue and not connect yellow and white from the 6 pin.

Thanks Timbersurf. :)
I've gone ahead and ordered a 6 pin and an 8 pin socket. I need to raise some more funds for the 4 pin socket, motor and mount but this is looking promising. :idea: :mrgreen:
Thanks

A quick couple of questions on the circuit board before I start if I may.
What size sould the "on-board" wiring be?
Should the wire on the board be the same size as the wires coming off the board from the DCC controller and to the motor?
I have 7, 16 and 32.
Thanks

7/02 is good for 1.5Amps, so will do for all the wiring

After sending a message to the seller, what I thought was a 4 pin DCC lead with socket to attach a decoder to my circuit actually isn't so can anyone point in the right direction please?
Ideally it would be leads to a 4 pin DCC SOCKET also with an adaptor to change the end from a socket to 4 pins.
Or vice versa, as long as the end can be change.
So reguardless wether a 4 pin DCC decoder has a socket or pins on the end the tester would be able test it.
Thanks
