  1. When he said "You need some 'uppers' for the late night track laying session" that's not what he meant.
  2. They would twist the other way "down under".
  3. If you have a noisy bus they will help. No harm in fitting them anyway. Don't get too hung up about where you fit them. They are purely filters for high frequency noise. DCC is not a transmission line, it's not about reflections, and they do not need to be at the end of every bus run.
  4. They've been discussed plenty of times on RMWeb. The bad reports are due to improper use. It's imperative that the correct connector is used (colour coded) for the wire being used. When joining droppers you need a splice connector, designed for exactly this sort of situation, that takes two different wire sizes. Still only works if the dropper is the appropriate size. That's really not the way to use scotchloks
  5. Every time a loco bridges the gap where you removed a feed, you are back where you started! Doesn't happen. You are up against the speed of light and would need a VERY large layout. It's almost certainly noise causing packets to be corrupted, usually due to poor wiring. To repeat an earlier question, what gauge wires are you using for the bus and droppers? How long are the droppers?
  6. You can use +Whetstone to force google to include that word. The problem then is you get all the pages where some idiot has misspelled wheatstone
  7. Why? Are you perhaps thinking of Wheastone Bridge? There is a Whetstone Viaduct http://www.forgottenrelics.co.uk/bridges/gallery/whetstone.html
  8. Having posted that, you may find your luck just ran out Seriously, we can get away with all sorts of corner cutting. Best practice is just that, the best you can do. Anything less will work, until it doesn't.
  9. No. If there were enough interest it would perhaps be a possibility for our SBOOST booster, but I'm too busy at the moment to even think about it
  10. Ah, the car that the wheels used to fall off!!! I learned to drive in my father's Allegro It was the version with the normal, round, steering wheel.
  11. If the booster doesn't shut down on a short then either it's not a short, the booster is faulty or your wiring is not up to scratch. Circuit breakers are useful for splitting the layout into different power districts so that a fault in one does not bring the whole layout to a halt. Using it to isolate track and accessories is one example of this. It's a waste of money to simply replicate a boosters own current limit. If you are using a booster with a stupidly high current limit then there may be a case for multiple circuit breakers but this comes under power
  12. If storing long term, make sure the foam is suitable and will not react with the paint on your models, or wrap in archive quality tissue.
  13. There will be some tolerance in the current trip level and the time delay but electronic devices are not like fuses or circuit breakers that rely on thermal effects and take time to trip. They can be designed to cut out very quickly at levels only a little above normal. Only Roco (or someone who has experimented) could say with confidence exactly how the cut out works. You should not assume you could operate above the stated limit. Old fashioned rewireable fuses, for example, could sustain an overload for many hours and would only break instantly on a dead short circuit (a fault in
  14. What rail material? You need to look at the resistance compared to copper bus wiring and satisfy yourself that it will be reliable when overloads or shorts occur. It's not necessarily a good idea, especially on large layouts.
  15. Back to 2D and etching I have often wondered whether PCB design software could be used. Set it up for two layers and draw copper areas for the two sides of the etch.
