I have had no clock in my house ever since I scrapped my VCR many years ago. However, I did miss a visible clock and wanted to make one. But when you make something, it must be special, at least that is my opinion.
At some point I was being silly and got the idea of making a 7-segment clock, but then a bit different. The result became this:
[attachment=1]
[attachment=0]
Features include:
There are still a few things to fix. Currently this is iteration three and there will be a fourth (and hopefully final) one. It does look nice, if I may say so myself ;-)

Features include:
- 72 7-segment displays in three rings; inner (hour) ring 12 displays, middle (minute) ring 24 and outer (seconds) ring 36 displays
- Light sensor for adaptive display intensity; lighter during the day, dimmed at night
- Movement sensor for waving interaction; show time/date with a wave of your hand
- Each segment individually addressable with 256 levels of intensity
- Ethernet connectivity for remote control and power entry
- NTP synchronization for (near) perfect time
- Some blinkenleds for indicative purposes
- Buttons and RTC for off-line time-keeping
- 3D printed case in four sections with Plexiglas cover and back
There are still a few things to fix. Currently this is iteration three and there will be a fourth (and hopefully final) one. It does look nice, if I may say so myself ;-)

There's something very neat about the symmetrical quadrants in the prototype. I love the projects on your blog.

Yeah, that was quite a bit of fiddling to get that to fit. The optimum was a 10x10cm PCB, so that had to do. The holes are actually very close to the border to get a seamless connection between the quadrants. The price for the 20x20 PCBs have come down enough to do everything on one large now and I have confidence that the design will work as intended.

The board is so wonderfully strange and odd that I wish that I thought about it before you :-) Well done and very cool.

Now you know how my brain works... wonderfully strange and odd. :-)

... that I wish that I thought about it before you :-)Use it as inspiration. Your designs have already inspired me (remember the battery clip holder).

Well done and very cool.Thank you.

Ah yes, the earring! That was another clever and artistic and idiosyncratic design. I hope you make more of those.
