Description

I wanted a binary clock for the geek in myself but didn’t want it too look geeky! Something I could mount on the wall and provoke question, rather than distaste.

‘Wooden Bits’ is what I created. It’s a 4×4 matrix created from laser-cut plywood sections. To add interest to the shape and prevent it from being a boring square, I used ‘kerf bending’ (close slots created from the natural bur of the laser) to form organic curves; the LEDs snake through internals, following the plywood form.

How to Read the Clock:

The four columns represent binary nybbles (4 bits) vertically, with the least significant bit (LSB) at the bottom. Each nybble is a binary coded decimal of the time: tens of hours, ones of hours, tens of minutes and ones of minutes (HHMM). For example, in the main photo the clock reads: 0 (0*1+0*2+0*4+0*8), 6 (0*1+1*2+1*4+0*8), 5 (1*1+0*2+1*4+0*8), 2 (0*1+1*2+0*4+0*8) – 06:52!

The cells are illuminated by RGB LEDs and by default, the time is shown in white (this can be changed with the ‘set’ button). To add interest, the clock has a quarter hour indicator: quarter time numerator number of rows become blue filled for 10s on the quarter. In the product photos, it’s showing 3/4 filled – 45min. At midday, a special rainbow effect displays for 1min (shown in the product photos too).

Inside is an Arduino with a real-time clock (RTC) to keep time. The clock has a coin cell so it won’t lose this time reference without power. The display requires a 5V 0.5A USB supply to function however – included. In order to set the time or display colour, one presses a small button near the power jack. The grid changes red to show setting mode; pressing the button increments the minutes.

I make these to order by hand so there is a lead time of up to 2 weeks. Generally it will be more like 1 week as I have one in stock. I am able to provide minor customisations for this reason however, such as LED colour, engraving or wood stain (natural is standard). Please ask if you have something else you think of.
