Good news - we're open for limited services in Wembley. Ujima House is now actively under refurbishment and we'd love your help in making the space the best it can be.
During this interim period donations and continued membership are greatly appreciated while we transition to our new space.
Holonyak is a Raspberry Pi. Holonyak was named after Nick Holonyak who invented the LED.
It runs voice announcers and doorbell in the Ground Floor at Ujima House, and drives an LED sign.
