What it is
Scrolling LED ticker message boards. There's one upstairs on the wall in the general table area and another one downstairs in the metalwork room.
They are driven by an arduino connected to ?Pi? boards and are controlled through the Hackspace IRC channel. Amazing hacker xxx and xxx set them up.
How to send a message to the LED ticker boards
- Connect to the #london-hack-space IRC channel
- Type your message in the following format:
?board [your message]
Example: if my name on IRC is RedTomato and in the #london-hack-space IRC channel I type:
The Hackspace boards will display in scrolling mode:
?board Do not be on fire
RedTomato Do not be on fire
Holonyak is a Raspberry Pi. Holonyak was named after Nick Holonyak who invented the red LED.
It runs voice announcers and doorbell in the Ground Floor at Ujima House, and drives an LED sign.
