This is a cute programmable PCB keychain. It's got four coloured LEDs that are controlled by an ATtiny13 and is powered by a CR1220 coin cell battery.
This is going to be a year to remember. Doctors and nurses saved a lot of lives and we are playing a big part in it by making sure we wear our masks when going out.
Every one of the 4 coloured LEDs in the badge is individually programmable. The badge comes with 3 different patterns already pre-programmed. The code is open source and you can modify or create more patterns for yourself.
You can select different modes for the LEDs using the built-in button. There is also a switch for turning off the power completely.
This fits well in your pocket and I've taken special care to make sure it doesn't snag anywhere, but you may choose to apply some hot glue to the back to make it extra smooth. Your choice!
The world has never faced a crisis like COVID-19. The pandemic is impacting communities everywhere. It’s never been more urgent to support the global response, led by the World Health Organization (WHO). That's why for every badge sold I will donate $1 to the COVID Response Fund.
Batteries not included Battery size: CR1220
Why are batteries not included? - There are shipping restrictions on batteries, so not worth the risk. You should be able to pick up these batteries (CR1220) cheaply in a dollar store.
How long does the battery last? - It depends, but roughly 36 hours if left on. It has a switch though, so consider turning it off when not in use.
Can I power it using something else? - Yes, I usually power all my badges with my bench power supply when testing. USB is also fine. The Attiny should be fine up to 5.5V.
