HO scale Controllers
2008. Difficulties in designing the required features into the proposed budget have delayed the first prototypes. Testing should follow soon now that some ideas have come forward on how to proceed. 2009 Feb: Prototypes are being tested. News should follow fairly soon. 2009 May: Tests proved very positive for the general use of the controller, but the special HO features did not work as expected on an actual race track. Another design has been done and prototypes are under way. More news to follow once testing is done. 2012: Revived interest and growing popularity with the HO scale has lead to...
PWM Controller notes and upgrades
2008: The most recent version is now ready, though still all hand made. Additional sensitivity adjustments have been included to compensate for the large variation in track power supply voltages encountered on the Slot-it challenge in the UK. New controllers will have this as standard and it is available as an upgrade to fit to the earlier versions. Price is £20 Upgrade and sensitivity Board features (Trigger 0.0) 10-Stage curve control:This sets the trigger feel by adjusting the shape of the throttle response curve from linear at setting '0' to logarithmic at setting '9' 10-Stage top sensitivity control:This changes the...
General Controller development:
2014 Aug: The multi-contact point wiper fingers have worked well, but still suffer from some degradation due to accumulated corrosion or dirt. The newest Contact boards have a nickel coating with a final gold plate coat. This, combined with the new high polish stainless steel wiper fingers, is hoped to provide the next step in giving very long contact service intervals and very smooth trigger feel.2015: The new Nickel/Gold and stainless steel has worked out well. These are now the standard materials used on all the controllers.2016: All this year the same contact system has been used. At the end of...
