Your Mug Will Like This Glowy Coaster2 min read
[Charlyn] desired to highlight their mates lovely mug collection, so the Glowy Coaster was born.
The coaster is created up of six layers of laser reduce acrylic. The major and base layer are slash out of obvious acrylic, providing a flat floor for the coaster. A major sample layer made of pearl acrylic has a thin piece of vellum set beneath it to offer diffusion for the LED strip sandwiched within. The middle layers are created of peach acrylic and have their centers hollowed out to give space for the electronics within. The prime pearl acrylic layer presents the coaster, as [Charlyn] writes, a “subtle touch of elegance”. The coaster alone is screwed alongside one another by an M3 screw at every position of the hexagon that feed as a result of to heat-established inserts.
The electronics consist of a quick NeoPixel strip, cut to consist of 12 LEDs pointed in in direction of the center of the coaster. The LEDs are pushed by a Trinket M0 microcontroller with a LiPo “backpack” to give energy, attachment details for the uncovered energy switch and recharging capability to the 110 mAh 3.7 V battery. The code is a a little modified NeoPixel “rainbow” wheel loop (resource accessible as a gist). The style data files are out there via Thingiverse.
Creations like these emphasize how considerably treatment and do the job goes into a venture with minimal beauty, in which conclusions, like the opacity and thickness of the acrylic or countersinking the M3 screws, can have massive consequences for the over-all aesthetic. [Charlyn] has an notice to detail that delivers an excess contact of professionalism and polish to the job.
Coasters are a favored for laser cutting and we have covered several unique forms, including
coaster bots, coaster engravers and even a shade altering, consume sensing coasters.
