This is a miniature replica of the Berlon clock "Mengenlehreuhr" designed by Dieter Binninger.


Working principle :

• There are 24 light signals arranged on 5 levels.

• The round box at the top shows the seconds (by flashing once every second).

• The first led raw contains 4 led and each box represent 5 Hours.

• The 4 boxes below each represent 1 hour.

• The third row contains 11 boxes which represent each 5 minutes. (note that the third, sixth and ninth led of this row are red to represent three quarters of an hour more easily).

• The 4 boxes in the last row each indicate 1 minute.

• The clock reads top to bottom.
