Notes from the Electronics SIG meeting 17th July
Six attended the Zoom meeting. Here are some notes of who has been doing what (the others of us have been "resting" from electronics!)
Stephen R. Has looked at the problem with slide switches at the back edge of layouts that are used to switch points and provide polarity changeover. These usually involve an unsightly hole in the backscene big enough for a finger. He has designed and printed extensions and covers for these, so the you effectively have a button that sticks out of a much smaller hole (that can be disguised). It pushes in flush with the backscene for transit.
Tom A. has been looking at using tiny 7-segment displays for route indicators on a layout; he has designed the PCBs for this and showed us the boards ready to take the components. A PIC will take the points signals (up to 8) and when signal clear is set will light up the route number.
Stephen E. Has acquired a "how-to" book on electronics and is having fun. He is also adding features to Dizzyworld – smoke units, church bells sounds....
Jeffrey has done some wiring diagrams recently for his group's modules and has rewritten the Module "handbook" so it can be applied to 0-16.5 (or NG7).
Plus they are looking to make an interface board to let them link with the Beds and Bucks modules.
He's starting on another 009 module, too
Graeme has sourced an ammeter and voltmeter for a controller for use on the ScOONS modules; he will also build a controller from a well-known design
The next SIG meeting has been pencilled-in for Thursday 11 September from 8pm - {TBC}
