[Charlyn] needed to highlight their friends beautiful mug collection, so the Glowy Coaster was born.
The coaster is built up of six levels of laser reduce acrylic. The top and base layer are slash out of apparent acrylic, giving a flat surface area for the coaster. A top rated pattern layer built of pearl acrylic has a slim piece of vellum set underneath it to offer diffusion for the LED strip sandwiched inside of. The middle levels are designed of peach acrylic and have their facilities hollowed out to give space for the electronics inside. The best pearl acrylic layer presents the coaster, as [Charlyn] writes, a “subtle contact of elegance”. The coaster alone is screwed alongside one another by an M3 screw at every single issue of the hexagon that feed by way of to heat-established inserts.
The electronics consist of a short NeoPixel strip, lower to consist of 12 LEDs pointed in toward the heart of the coaster. The LEDs are driven by a Trinket M0 microcontroller with a LiPo “backpack” to give energy, attachment points for the exposed ability swap and recharging capability to the 110 mAh 3.7 V battery. The code is a slightly modified NeoPixel “rainbow” wheel loop (source offered as a gist). The style and design information are out there through Thingiverse.
Creations like these spotlight how much treatment and get the job done goes into a venture with nominal magnificence, wherever conclusions, like the opacity and thickness of the acrylic or countersinking the M3 screws, can have substantial consequences for the over-all aesthetic. [Charlyn] has an focus to detail that provides an excess contact of professionalism and polish to the task.
Coasters are a preferred for laser cutting and we’ve covered a lot of diverse sorts, which includes
coaster bots, coaster engravers and even a shade transforming, drink sensing coasters.
