OO Cabin Shelf - finding why CDU isn't switching 2 point motors simultaneously
Вставка
- Опубліковано 14 жов 2024
- This past few evenings I've been doing loads of bits and bobs, I've made wire frame trees with seafoam, but had issues with the quality from wwscenics so only managed 3.
I've glued down some more of the trackwork over by station 1, and also added landform to the tunnel entrance by this station in prep for static grass.
I've been messing about with electrics and fitted a tester station lamp fitted to a 3v battery pack for the time being.
Finally I set about getting the points all wired into the same loop, moving the CDU and testing the mimic board. That's when I ran into issues, this video focus is on the issue where when firing 2 points motors, only 1 was moving and what I did to find the root cause.
Please leave a comment if you have any 💡 ideas on better approach to the mimic board.

The trees look great lights looks great too.
Am not electrician.
@@AdiPullen thanks Adi. Trees were fun but I got poor quality seafoam from Wwscenics as end of Harvest season so that was a bit frustrating. Getting there.
The electrics are quite fun but totally limited in my knowledge
Prewired Sub D connectors have very small wires to the plug in the multicore, that means high resistance, for the high surge current that solenoids use. Cat5 cable is similarly too high resistance for solenoid motors, especially if they are a long way away. Sub D connectors are OK, but dont use the cheapest as they wont handle the current, use minimum of commercial or better, industrial type (gold plated) that can handle over 3 amps, and you will then need to solder to the connectors with decent size wire (equal or greater than 16/02). As multicore cable gets expensive after 7 core, I think you will end up with 4 multicores
@@TimberSurf wow ! Fantastic insight Timbersurf thanks. So you don't think I'll be able to get a single cable from the points? 😞
@@TimberSurf reread this and understand now I've activated brain lol 🤣 the cable is 30v rated, no idea on amperes but should be fine. Have you seen anything similar to what I'm trying to do before? I'm sure I'm not the only one trying to make a single walkabout panel. Appreciate your post and advice. Thanks 👍
@@TimberSurf would these work better you think? uk.rs-online.com/web/p/automotive-connectors/8010941?cm_mmc=UK-PLA-DS3A-_-google-_-CSS_UK_EN_ePMax_Prio2-_--_-8010941&matchtype=&&gad_source=1&gclid=CjwKCAjwmaO4BhAhEiwA5p4YLwtTJcl1VYJYvHFTwYfA7vYxwmDnhMS4mYahj4vmcMvBzeZDFOMVsRoCV8sQAvD_BwE&gclsrc=aw.ds
@@_RandomPea Not really, the male is for pcb mounting only and the female will need the pins crimping with a specialist tool. Cheapest, most robust, easy to wire solder able, are GX16 Aviation Connector, available inline and panel mount and only £1ish per side.
@@_RandomPea Not really, the pins need crimping with a special tool and the male is for PCB mounting!. The cheapest, most robust flexible range of solderable connectors, is the "GX16 Aviation Connector", they can handle the power and are inline or panel mount and are just £1ish each. Up to 8 pin only
