Having installed the furniture some illumination was required and I was pondering how to achieve this without kilometers of wire and keeping the roof removable.
So I came up with this...
Having already threaded the wires through the cavity wall I cut some 2mm o/d brass tube and soldered this to the wires to create sockets. A 2mm drill was pass down the cavity wall to create the location points for the sockets.
Here the sockets have been installed held in with a drop of araldite.
The plug were made up from brass tube, wire and a piece of scrap to form an anchor and soldering point for the lighting bus. I also cut two rebates in the underside of the roof to hold the anchors.
Here the plugs have been installed, again, held in with araldite and the tops cut flush with the top of the roof. I also cut four pieces of vero board for mounting on the underside of the roof.
This is the idea. The pins were trimmed to ensure the roof could be slid on under the chimney capping and pushed home.
The four pieces of vero board were glued to the underside of the roof and a lighting bus made up from brass wire. The 3v SMDs (surface mount diodes) are wired in series. Channels were cut (circled) to route the wire over the interior walls.
Before reaching this point I had started on the roof top which is why you can see the styrene through the bottom roof mounting holes.
Install the roof and add some power.... the lights are on but nobody's at home.
These are supposed to be warm white LEDs and at first I was a bit disappointed as I would have preferred the filament bulb glow. However, I have grown to like these as they remind me of the ring fluorescent tubes my grandparents used to have in their dining room.
Yep, no-ones home...
And the doh! moment
- I forgot to take photos of the construction of the roof top. The concrete roof has a slight apex and to create this I glued a strip of styrene down the centre of the roof and added two styrene panels. The roof is currently in grey primer.
