[Charlyn] desired to emphasize their mates beautiful mug selection, so the Glowy Coaster was born.
The coaster is made up of six levels of laser lower acrylic. The leading and base layer are slash out of clear acrylic, providing a flat surface area for the coaster. A best sample layer built of pearl acrylic has a thin piece of vellum place beneath it to give diffusion for the LED strip sandwiched inside. The middle levels are built of peach acrylic and have their facilities hollowed out to offer room for the electronics within. The best pearl acrylic layer provides the coaster, as [Charlyn] writes, a “subtle touch of elegance”. The coaster by itself is screwed together by an M3 screw at each stage of the hexagon that feed by means of to heat-established inserts.
The electronics consist of a quick NeoPixel strip, reduce to involve 12 LEDs pointed in towards the centre of the coaster. The LEDs are driven by a Trinket M0 microcontroller with a LiPo “backpack” to give electric power, attachment points for the exposed electrical power swap and recharging capacity to the 110 mAh 3.7 V battery. The code is a marginally modified NeoPixel “rainbow” wheel loop (resource out there as a gist). The style files are accessible by Thingiverse.
Creations like these emphasize how a lot care and function goes into a task with nominal splendor, exactly where conclusions, like the opacity and thickness of the acrylic or countersinking the M3 screws, can have massive implications for the general aesthetic. [Charlyn] has an attention to detail that provides an added contact of professionalism and polish to the job.
Coasters are a most loved for laser reducing and we have protected numerous diverse varieties, such as
coaster bots, coaster engravers and even a coloration altering, consume sensing coasters.
