A kit of parts to build a simple but very unusual and eye-catching circuit:- a Binary Timer Display! Just like a binary clock, you have to do some mental maths to work out how long you are setting the timer for!
To make the complete timer, you will also need a 14M2 Motherboard kit, 70-1063.
The binary timer display PCB lends itself to any projects that need 8 (or 9) LEDs and has sound capability which is shared with an analogue input. It makes a great running light too, easily incorporated into the binary timer routine.
Kit contains printed circuit board and standard components
You will also need 14M2 Motherboard kit, 70-1063
