<p>When I started using the PiSprog and JMRI I realised that I needed to be able to isolate a loco for programming because the PiSprog does not have separate main and programming track outputs.</p><p> </p><p>

It became obvious that I would need some section switching and since the storage sidings were not yet properly powered, relying on power switching from the electrofrog points alone, I decided to generally improve the electrics.</p><p> </p><p>

After inserting isolating joiners where needed and gluing down the siding tracks, I soldered lots of new droppers and then dismantled the layout so I could get to work on the main board.</p><p> </p><p>

A simple switch panel was made from an aluminium door "finger plate" from B&Q.<br /></p><p> </p><p>

LED's with suitably sized resistors were soldered across the DCC outputs of the switches to give some more visual feedback of the powered areas. (Do these count as DCC "Districts"?)<br /><br />This was mounted behind a hole cut into the side wall of the baseboard.</p><p> </p><p>

The PiSprog was mounted into a customised case and fixed to the underside of the board.<br /><br /><br /></p><p> </p><p>

All wired up and the layout boards re-assembled:<br /></p><p> </p><p>

You can see that I've attached the monitor to the board on a swing arm, added some LED lights, protected the switches from accidental knocks and made a cassette for turning locos. The cassette will probably also be used as the programming track.</p><p> </p><p>

Mounting the PiSprog under the board keeps things tidy but as I discovered this morning plugging cables into it is a bit of a pain. Maybe needs some more thought.</p><p> </p><p>

So hopefully now I can really get to grips with the software and CVs.</p><div id='attach_wrap' class='rounded clearfix'>
