Mr Junophor offered me a big peace of mahagony wood. So I had the basic material for a steampunked binary clock.
The clock is driven by a CControl micro controller and some solid state relais.
A small Basic program reads the internal clock (controlled by a DCF signal), converts the values to binary format and sets the bulbs.
A 5V relay is used to simulate the ticking of a clock.
Step 1: The wood and materials
Step 2: The electronics
The bulbs are connected to an interface board with solid state relais and the driver IC´s. A ticking sound is simulated by a small 5V relais.
I used this: Solid State Relays (S102T01 Series) and this driver IC´s: ULN2803A because the MC board is only capable of driving 10mA.
The resistors are for limiting the current.
Step 3: Mounting the sockets
Please see details below.
Step 4: Mounting the electronics and cabling
A small 5V power supply gives the power to the electronics.
The small relay simulates the ticking sound.
I used two switches, one for disabling the ticking noise. :-)
and one for switching the bulbs off during night.
During the tests I found that it is better to raise the antenna a bit. The signal is now stronger and the clock syntonization is faster.
