Outlets will provide you all sorts of gaudy vacation ornaments, but there’s nothing at all like the model and class accomplished by making your very own. [w3arycod3r] did just that, whipping up the exciting and festive Neodriver Ornament.
It’s a battery-powered construct, and operates off an rechargeable 18650 mobile which delivers quite a few days of operation at a very low duty cycle. An ATtiny85 is charged with sending out instructions to a variety of NeoPixel units, from rings to rectangular arrays. [w3arycod3r] then built a variety of PCBs that could carry the hardware and battery in a nicely-well balanced package that would hang nicely when suspended from a ribbon on a Xmas tree.
As is constantly the fun portion with addressable LEDs, [w3arycod3r] whipped up some pleasurable animations to match. The 5×5 rectangular arrays of NeoPixels are ready to deliver scrolling textual content, while an additional animation blips out the RNA sequence of everyone’s minimum preferred coronavirus, SARS-CoV-2. Finding everything to in shape into a ATtiny85’s 8 KB of code house and 512 byte EEPROM was a obstacle, but slimming down the Adafruit NeoPixel library and working with immediate AVR sign-up manipulation in position of frequent Arduino capabilities assisted.
Over-all, it is a fun holiday develop that seems excellent on the tree. Alternatively, take into consideration producing yourself some rheoscopic ornaments this holiday break period. And, if you’ve whipped up your own fun getaway build, toss it on the tipsline!
