10:00 10-NovVirtual Area Group - CBUS on P4 - Paul TownsendPaul will describe how he has planned the deployment of CBUS on a large P4 layout. Having used my designs of CMOS hard wired logic for decades on my old layout, I wanted to use Merg designs for my new layout to gain sophistication and flexibility for partial automation at reasonable cost. Of the available buses, I will explain why I chose CBus and how I have evolved my implementation both for P4 Broad Gauge Dartmouth and its baby brother, Pseudo-Dartmouth in N Gauge. The presentation will include videos of the installations and operations.Zoom video callLink

  • How kits work - a series of calls, each discussing the how one particular kit works - now schuduled
  • Types and use of baseboard connectors - covered in Demystifying Components -Wires and Connectors
  • Oscilloscopes and logic analysers for hobbyists - now scheduled
  • Using the FCU - a multi part course is being considered including the use of the FCU to configure individual 2nd generation modules.
  • Testing boards (use of various pieces of test equipment and the way to go about it) - A Test Gear Buyers Guide has already been presented.
  • Neater Methods of under board wiring
  • Best practice for wiring different bus types
  • Layout control buses
  • CBUS wiring strategy on a large club O gauge layout - scheduled
  • CANPAN wiring
  • Servo and Servo Mounts
  • Building CANVOUT
  • Prusa 3D Printer
  • 3D scanners
  • Photogrammetry - generating 3D models from multiple photographs
  • CBUS Beginners Kit.

Members can suggest topics at any time using the member email system.

How do Video Calls Work?

The calls last one hour and to participate, members need a mobile phone, tablet or a PC / Mac with a camera and microphone.

Calls are scheduled in advance and are held on each Tuesday of each month at 10:00, 12:30 or 18:30 GMT or BST. Topics are agreed in advance.

When it is time to start a call, a voice and video conference is opened up which has thumbnails of each video participant and any shared presentations or desktops. The call leader facilitates the call and the discussions and tries to get through the agenda in the agreed time. Zoom has two views available. The first is the speaker view which selects the video stream from the person speaking. The second is Gallery view which shows streams from all participants.

If you would like to try out Zoom, then there is a test meeting service where you are the only participant and you can experiment with the various options available.

This link is available to anybody, not just members of the virtual area group.
