Introduction: Easy LED Doll's House Lighting
My Dad built this amazing doll's house for my daughter, inspired by plans but following his own design. The only condition was that I would have to do all the electrics once it was built!
I wanted to have safe lighting, with independent switches for each room, and decided on LEDs.
Step 1: Fitting the Cabling
Dad had floored each room (and created tiny roof tiles) with sample floor tiles from DIY shops, but had the forethought to cut a groove in each room's floor to hold the lighting cable, including a hole in the centre of the room to the ceiling below and round the back of the house.
The grooves were then covered up with the tiles and the interior finished off, but again thinking ahead Dad put a piece of string in each groove with the ends sticking out the holes, to help guide the cables through.
The trouble started on our way back home, as the rear of the house was next to my son's seat in the overcrowded car - to be honest if I was a bored 4 year old and saw bits of string sticking out I'd pull them too just to see what happened.
With the guide strings missing in action I had to poke the LED cables into the holes at the back, then hook them through the ceiling hole. This was tricky, in the end I used a tiny hook from a vintage lighter service kit to pull the cable through, something like a crochet hook.
Each LED had its own two-strand cable, and over 10 metres was used! With the cables in place (and children warned not to pull them out) the LEDs were added. These were soldered to the ceiling wires, with their bare legs covered in white heat shrink, using a wider section of cable insulation to secure them in the ceiling hole.
Step 2: Switch Madness
Having a switch for each room seemed like a great idea but came with an awful lot of cabling!
I used a project box to hold the switches (in the same layout of the rooms in an M shape) and thankfully it was deep enough to hold the nest of wires. A DC socket was added to the box to allow flexibility for the power source and after fitting it to the side of the house the remaining loose cables were tamed with some conduit.
In retrospect I would have used bigger switches as these were fiddly to solder, but after accidentally melting a few they were all in place and working well.
Step 3: Furnishing
The LEDs proved to be the perfect light source for this project, I chose the "superbright" ones and they look just like tiny bulbs, powered by a 3x AA battery enclosure connected to the DC socket of the switch box.
With some furniture (and characters) added the brightly lit rooms really came alive, showing off the detail in the decor that was missed in natural light.
Next steps are to build some shades for those bare bulbs - keeping my eyes open for ping-pong balls, bits of torches, whatever works!
