[ANTALIFE] is going to tie the knot sometime in 2017. Instead of sending out paper announcements or just updating his Facebook status, he wanted to give their family members something lasting and memorable, like a small trinket with a pair of light-up cats.
This project is pretty simple in theory. A pair of RGB LEDs cycle through the colors of the rainbow with the help of an ATtiny25 and resistors carefully chosen for each LED. But there are several challenges at play here. [ANTALIFE] wanted to design something quite small that would last at least a day on a single CR2032 coin cell. This project was his first foray into SMD/SMT design and construction. We think that this warrants its own congratulations, especially since it looks as though he made at least a dozen of these things.
[ANTALIFE] made things much easier for himself with the purchase of a cheap hot air rework station and used a chip clip to program the ‘tiny. The cats are a design from Thingiverse, which he modified to turn them into bride and groom. Watch a whole line of them glow after the break. We sincerely hope that a larger version of these cats end up on top of the wedding cake.
For anyone with an undying love blinkenlights and impending nuptials, don’t forget the light-up invitations, wedding attire, and centerpieces.
Thanks for the tip, [Brendan].

A chimera of frog and human in the offing? Don’t see any cats.
A cat with a veil and a cat with a hat. The ears under the veil do look like frog-eyes though.
Tonight on HackADay News, man discovers an arduino, compiles the default blink sketch, hook up to an led, and stuffed it inside of the 3d printed cats. HACK CONFIRMED. Later, ILLUMINATI’S KICKSTARTER CONFIRMED.
Sir you really don’t get it! The hack here is how he managed for his future wife to approve the expense of a solder rework station. Damn! Why didn’t I come up with something like that when I got married?! I just needed to come up with a trinket that required a 4 channel MSO to develop it!!!
Stay salty senpai
Congrats to the happy couple!
From the headline and picture i assumed the color of the cats was significant, like red means they had a fight wedding is off. Green means go yellow means someone got too drunk at the bachelor or bachelorette party and the relationship is a little rocky.
So when they divorce do the cats explode?
The wife gets the cats (and the house). The man pays for them.
