We use Slack as our messenger at work.. Its an awesome program, If you haven't seen it you should give it a glance. My main gripe with slack however is that with multiple desktops, VM's & assorted windows i miss a few 'new message' alerts..
Not any more!!
1x ATTINY85 Mini Usb Development Board / DigiSpark clone ($2.50)
1x Neopixel strip (left over from another project)
1x Piece of scrap purple hart (2" x 7" x .75")
1x Piece of scrap clear acrylic (.25" thick)
1x Quckly slapped together Python script..
boom... I call it.. the "Slackifyer"
When somebody is typing a message to me in SLACK the lights subtly flash.. If i have an un-read message the lights flash more annoyingly.
Its hard to get a good picture of it in my dimly lit office..
But i'm happy with it!
(Yes.. i know i haven't sanded down the tabs off the side of the acrylic.. but i slapped this thing together in a few hours.. i'll get around to 'finishing' it sometime)
