Tell us about yourself!
Thanks for you comment. I can only enter 1 contest with this instructable and decided to go with the concrete contest.
Yes!... that's the idea I am contemplating for my next project. I will have 4 different light sources.The limiting factor here is the bundle diameter.
Thanks!The BOM is under the Supplies section of the instructable. It includes the type of optical fibers I used.Steps 2 & 3 have a couple of images to show you how I set the fibers to easily tuck them into the concrete
Yes, definitely. The concrete and fibers would be exposed to the elements just fine while the light source is protected in a water-proof case or under the piece if it is a table. Depending on the colour and use of the concrete piece, you may want to seal it. The sealer will protect the pigmentation of your concrete that would otherwise degrade after long UV exposure and will also protect against stains.
Thanks!Lights are visible in daylight and very bright in the dark. There is also an option to adjust the brightness of the light which is very cool and flexible
