I have 3 "background process" LED projects going on, just chugging along collecting bits until I throw it all together.
Firstly, strips very similar to the above turned up in Canadian Dollarama stores for $3CDN for ~3 feet hooked up to a 3xAA battery box with a switch. These are a 5V strip though rather than a 12V strip, the resistors on the 12V one appear to be 240 Ohms, where as these are 75 Ohms.
My idea was to deploy 3 strips and electrically series them so 12V can be used, on 3 sides of the cabin. I have in the past seen stick on silicone feet about half inch square, that were frosted clear look and had a divot/recess in the back, I thought those would work pretty well for individual diffusers over each LED. I was also looking for some trim to go over maybe, have holes drilled per LED.
Secondly, a post christmas grab the other year was a set of LED icicle light type things. At the point I picked them up LED household bulb replacements were stupid money still, like $30 a pop, and they were a few bucks. I thought actually I could string them around a workbench for even/cheap illumination, but on household 115, they flicker rather annoyingly. Then I lately noticed, that I'm getting a number of vitamin/supplement bottles that are blue, some that are green, and some that are orange.... so I'm gonna make a set of awning/gazebo lights with them, maybe mask the bottles into lantern grid patterns.
Thirdly a "Hey that's a small solar panel for a couple of bucks" grab at a thrift the other week turned out to be a solar rechargable shed light, with up to 6 hours run time off full charge. The light unit/diffuser is okayish, wondering about using it for the reading lamp. Wondering whether actually to rewire it to 12V or leave it as an independent system with the panel catching rays outside somewhere.
