Alarm clock – the guts

Here’s the insides of the clock. The main black board is the led array. Mounted on top is (from left to right) custom FM receiver and RDS demodulator, class D digital audio amp, cortex M3 ARM CPU.

My new alarm clock

I decided not to make the synth, since there’s so much good stuff coming out on the iPad. So I took the bits, added a fm receiver, and made a new alarm clock.

Looks great, and does exactly what I want it to. Nice gentle wake up sequence.. Gets time from rds.

Only problem is that if there are any bugs then I’ll be late for work :)
