Re: Triang Class 37 non runner, testing amature

Just to add to Irondukes advice.
With the meter connected and reading turn the motor slowly and as the commutator moves the reading will show the resistance of each armature pole winding, with a blip as it passes the gaps in the commutator segments.

Re: Old Locos, DCC decoders and Hornby Select

Although your v1.5 Select will operate all 29 functions (F0-F28) it still cannot amend CVs other than address, accel and decell. To be able to do this, which is an definite advantage, you need to send it back to Hornby for update to v1.6 (v2.0 is the functionally identical version for post facelift ...

Re: Dcc problem.

I have updated firmware before on accessory decoders and frustratingly found they would only read back as the old version, until I reset it just like a loco decoder whereupon the version now read correctly as the updated one. As you say this DCC can be fickle.

This will be a special rectifier that can cope with the frequencies of DCC. it's easy enough to obtain a replacement. https://au.element14.com/multicomp/bav99-7-f/diode-ultrafast-recovery-125ma/dp/2306039?st=bav99 UK folk...

Re: Station Layout - Suggestions/Feedback welcome

Whilst the concept is good, you won’t have room on those track lengths to get the rolling stock and loco movements in. One coach will practically fill an R601 straight and a small loco an R600 short straight. The small platforms will not take more than a small loco and one coach. Not really enough r...

Re: Best free/open source software for pc/phone?

SCARM but again the free version has a track piece limit, but the free version will still view larger plans made on another device, just that you cannot edit and resave such a plan.

If you buy the licence and need a second copy on another device then you can get it half price.

Re: Critique my layout and help setting the scene

Check that you have adequate clearance between the inner and outer loop curves at the front to avoid stock clashing when passing.

Re: Speed and acceleration problem

Surely the installed decoder decides what max voltage the motor and function outputs see. You can set what controller output track voltage you like within any particular decoder limits and the onboard gubbins will take the output voltage down to design spec. E.g. TTS decoders have a system limit of ...

Re: PCB board cutting

I used 6” x 4” single sided copper clad sheets cut into 1/2” strips. As I was using double tracks I screwed them down and soldered them to the rails before cutting just the copper between each rail pair and both tracks. 46F5E671-99F8-4E35-96D7-1D974D7FE33A.jpeg 505A2CB2-6AE8-4FDE-A3D1-E65A05FFB10F.j...
