  1. The big issue writing your own control system is firstly you have to write interface code so you can control an existing command station , depending on the system this can be quite complex then once you have control of the system you need to decide what functionality you need , again. This results in significant code all in all a big task
  2. personally I have used the new App extensively for shunting ( no kadee shuffle however ) and I do not find NoelGs issue with control. I find I can keep my finger position instinctively and move it around. I think there is always an issue with coming to conclusions after a small amount of usage. Over time you build up a " muscle " memory and often what is clumsy initially becomes second nature with practice. I have no issue accurately buffering up etc and Noel can see this in operation at our Easter exhibition if he wishes I also dont find it an issue to glance at the screen from time to time and with sound equipped locos , you end up looking the screen a lot anyway ( and again particularly with locos that require a brake function key to stop ) . Ive used the NCE pro dog-bone and I personally don't like its operation , so its very much horse for courses I have also customised the sensitivity of the apps throttle.
  3. Just for clarity For others Noel, there is no “ software bug “ in relation to short address 100-127. Roco , as did many other DCC manufacturers chose to limit the short address range to 2 digits , ie 1-99 and to interpret 3+ digits as extended addresses. This is entirely consistent with the nmra spec as the standard doesn’t mandate what specific address range any particular manufacturer has to provide. This is only an issue where you switch locos from one command station to another and only for locos programmed with short addresses in the 100-127 range the oft quoted advice is that in general for interoperability don’t use short addrsess 100-127 i just wanted to clear up the issue over a suggestion in Noel’s post that the Z21 isn’t following the nmra spec the underlying mistake is actually nmra should not have allowed the primary addressing and extended addressing scheme to have overlapping ranges Our experiences with the z21 and Z21 have been very positive and while we have a WiFi Multimaus , it almost never gets used Dave
  4. Thanks Mike nice pic , neat edges , that'll do me me ! dave
  5. A limited number of advance discounted e-tickets are on sale https://billetto.ie/e/wexford-model-railway-club-easter-exhibition-tickets-347160 Come and visit whats promises to be one of the biggest , if not THE biggest model railway exhibition in the country with 35 layouts , great trade support and fabulous catering ( check out our Station cafe , inside the hall , for home cooked treats and great value ) Dont miss it ( and its in the sunny south east , I mean can it get any better )
  6. The prototype had the barrow crossing to facilitate the signalman unfortunately , moving the crossing , so that it runs perpendicular creates an end point that is trapped in a loop and looks non sensical . The angle across is about 20 degrees off perpendicular. Should i build it , or drop the whole idea
  7. Take a 2m length of wood , try keeping it level while rotating it through 180. Now imagine it’s filled with 300-400 quids worth of stock next .....
  8. My BR ( W) layout needs a barrow crossing from the signal box to the opposing main platform. The prototype had one in in my case the nature of the compromise is the barrow crossing will not be perpendicular to the track but slant across 4 lines I’ve never seen a barrow crossing from memory that’s not perpendicular but maybe they existed would the edges of the timbers be cut or simply standard lengths staggered across etc thanks again Dave
  9. I think thats definitive from that perspective , ie if it has a dcc decoder run it in on dcc else DC Clearly from the manufacturers perspective , the issue is dismantling the loco , not the issue of DC versus DCC
  10. Indeed , it is , I severely admonished my calculator
  11. 12V white light led strips tend to be around 5 - 7watts per metre , ie around 2-2,5 A, so a 3A system should be fine
  12. The magnet needs to briefly trigger the sensor and the led should start flashing , retriggering the sensor will stop the flashing , so make sure you dont have the magnet near the sensor . Also if you are testing the system , you need to move the magnet reasonably quickly away from the sensor, if you leave it near or move it very slowly my experience is you can get false triggers. and hence it briefly is enabled and then disabled
  13. To me the track plan looks so unprototypical as to render it unbelievable , especially the lower section. The run around using the platform is OK , as in lightly used branches , it was common enough configuration The whole goods yard is far too complex for a prototypical layout , there seems to be complexity for the sake of it , yet Railway companies tended to justify everything based on running need and costs, here the general desire for simplicity also if those are 1 foot squares, the loco release is tight enough !
  14. in my experience plungers but too much pressure on the rims and in certain cases start to interfere with the sideways movements of the axle my own solution is phosphor bronze wire , rolled to create a "spring" with a extended arm that rubs on the top of the tyre and not the flange back. If the loco is sprung or compensated , you need a quite delicate spring effect The spring section can be threaded onto an insulated rod or soldering to a PCB type carrier
  15. practically , reliably detecting the presence of a DCC decoder as distinct to the DC loco would be difficult to effect reliably , secondly feeding a section automatically based on that dubious recognition would be problematic as a mistake would enable DCC power to a DC loco ( and that may not be obvious to the operator ) Hence , short of throwing a considerable amount of electronics to make the detection reliable , its not really practical Added to this is the difficulty in controlling locos with all the same address , Note that there is a " broadcast " DCC address , but gain not all decoders in my experience react correctly to it Basically its a non runner
