Last chance! This is the final batch of Joker badges. Once these are gone, I do not expect to produce any more. Thanks!
What is it?
It's a wearable electronic badge inspired by the Joker cards found in a typical deck of playing cards. One half features a happy, smiling Joker, flanked by colorfully-lit stars and bells on his hat. The other half features a decidedly less jovial Joker, with red glowing eyes and pentagrams.
Why did you make it?
This badge is the result of an idea that just, without warning or provocation, popped into my head one day. There's no particular event or season that inspired it; the idea just amused me and I wanted to see it brought to life. Besides, bad things happen if I ignore the voices in my head...
What makes it special?
The badge is aware of its orientation. Feeling happy and playful today? Let your fellow astronauts, fry cooks, students, supreme court justices, accountants, baristas, librarians, code monkeys, plumbers, surgeons, shoe sales assistants, zookeepers, ... or whoever (I have no idea what you do!) know by attaching the lanyard to the happy Joker side. The jovial Joker will be lit with blinky goodness signalling to all that you are oh-so-happy and looking forward to their many exciting questions, comments, and small talk about the local sports team.
On the other hand, if you're sick of Steve telling you that you're over-cooking the fries or of Dr. Rick's constant critiques of your brain surgery skills [that guy is SO arrogant], attach the lanyard to the evil Joker side. His creepy eyes and red glowing pentagrams should get the message across.
Note: I can't be held responsible if the people around you lack the social skills to properly interpret the Joker's signals.
Techie Details
The badge is controlled by a custom processor module that I also built (a modified version of the excellent HCC module by @idlehandsdev). It features a Microchip SAMD21 32-bit microprocessor and is Arduino Zero compatible. Lighting is accomplished via a total of 29 LEDs of 3 different types. It's all powered by a 3.7v LiPo battery (included), with an on-badge charging circuit to charge the battery automatically whenever a power source is connected to the USB (micro B) connector. To charge, connect to a laptop, desktop, powered hub, USB wall adapter, etc. (none of those are included -- but you can probably borrow something from Dr. Rick [that guy has EVERYTHING]).
