Panel meter Moon phase Clock

A mantle style clock that displays the phase of the moon with an large old (30/40 years) analogue panel meter

I got my hands on two old very large 12x12 cm ( 4.6x4.6 inch) panel meters which were never been used. The display was still blank. The design for the display was made in Adobe Illustrator and printed on sticker material which i laminated with matt laminator pouches.

    Finally found some time to update my project.

    All electronics are working.

    Installed everything.

  • New Bottom panel

    I wasn't very happy with the bottom panel, it looked cheap and was to small for all the components that had to be installed. I had to make a new one.

    After locating where the parts should go I drilled the holes for the standoffs.

    When i started this project I wasn't sure how I would set the the date and time. The easiest way was to set it with an Arduino via serial but if this clock would end up with someone else with no programming experience this would be very hard. So I went the extra mile to create a menu to the date and time could be set on the device itself. First I tried to mount the menu on the bottom which meant you had to flip the clock over, but this turned out to be very unpractical. Eventually I decided to put the menu on the backside together with buttons and a DC-in connector. I didn't want to screw this up because the panels where already lacquered.

    Cut the holes and recesses on the cnc (The scratches are form a light sanding).

    All the parts mounted

    The Lcd screen displays the date, time, moon phase percentage and the temperature. The functions of the buttons will be, blue: Menu/set/next, red: up, black: down, yellow: backlight (which will automatically switch of after about 30 seconds).

  • Mounting the electronics

    SephenDeVos08/21/2016 at 12:57 0 comments

    For mounting the electronincs I use a little piece of plywood and drilled the holes for the components.

    I bought m3 brass insert-nuts and tapped them in with a hammer and a longer m3 bolt. To hold them in place I put a little superglue/cyanoacrylate gel on them before I tapped them in.

    Added the standoffs.

    The hole without a standof is to a attach a zip-tie for a little strain relief on the power cable.

    All the parts mounted.

    Added extra nuts in the frame for holding the electronics plate.

    Everything mounted and ready to go. Now waiting for the lacquer to dry on all the panels

    I drilled all the holes in the panels to do a test fit if everything lines up the way i would like. Must tap the top holes in the aluminium profiles. but I broke my tap. so that has to wait.

  • Cutting the Panels

    Finally had some time to play with my recently bought Ox CNC Mill. After destroying a few bits and a lot of wood i eventually had some nice panels. These panels were cut from ±5,5mm (±0.22") 3 layered plywood.

  • Building the Frame for the Clock

    For this clock i'm not going to use a donor clock, instead i'm going to build it from aluminium profile and cover it with plywood. This will give it a nice industrial look.

    Ordered aluminium profiles and 90 degree connectors from Misumi and m3 x 8mm hex screws. And after 10 minutes fiddling it looked like this. Just a quick pre-assembly so the alignment is still a bit off.

I really like this project - I can imagine an array of meters reading tides, precipitation probability, percent cloud cover, expected high and low daily temperature, snowfall predictions, and others, all scraped from web weather resources.

A while back, I was working on a similar concept that showed the daily movement of my retirement portfolio (+/- 5% scale).  Then, the global economy melted down, and the thing would have just sat on the left end stop for months at a time, so I dropped the idea.

Yours is a much better application!

Thanks! haha, the reading tides has crossed my mind. I really like the idea of the percent cloud cover. I was planning on doing a project with an array of meters but when i came across these i had to do something with them.

So many ideas, so little time... :)
