What happens when you have a large stash of clear LED’s but you want or need diffused models for a project? You could go buy some more, but [Tyler] says no! Go grab some scrap from the shop, and make yourself a sand tumbler to diffuse the LED’s you already have.
The tumbler mechanism is similar to a rock tumbler, but is crafted out of bits of wood, some rods, a spaghetti sauce jar, and a DC motor which is available out of the types of machines we already tear apart. Once constructed, fine dry sand and the LED’s are loaded in the jar and is set to tumble for several hours.
Once done its easy to fish out the now diffused LED’s, which have a more even glow over their clear counterparts which shoot most of the light directly out of the end. Although it takes time, its a lot easier than trying to manually diffuse LED’s by hand, and if you need more than just a few its a massive labor saver.
Join us after the break for a quick video showing the results of different attempts during the learning process.
