Led clock mini circular11/8/2023 We now move to the back of the clock base to cut pockets out for the quartz clock and the Wemos D1Īs with any new design there is always something that could have been carried out better with hindsight of course. We now create a profile cut using the same bit, we can cut the 8mm centre hole out and also cut the clock body out, add tabs, this will create tabs around the 8mm hole to, just delete these. The bit is a 6mm 2 flute flat bottomed router bit. To the cutting section: for the recess around the circle this needs to be 11mm the width of the LED strip, so a pocket is created as in the photo. Starting point will be the centre of the MDF.Ĭreate a circle 318.5mm and another circle in the centre 8mm then then another circle 430mm offset this to 6mm inwards to create a band. Set up will be for 15mm MDF and dimensions for the piece of MDF I am using is 500mm x 500mm ![]() ![]() The clock body needs to have a 318.5mm diameter inner circle, this will accommodate the LED strip, then we need a pocket of approx 50mm for digit illumination, this leaves a lip of 5mm around the perimeter of the clock body. I painted the dial with blackboard paint using a small foam roller. Lightly sand the piece to remove tabs etc, Rename, and save the g.code and cut out on the cnc machine. In the cutting section of Vetric, use the pocket tab for the digits and centre hole, depth is 6.3mm to cut right through the MDF, 3mm flat bottom 2 up cut router bitĬutting out the clock face we select the profile tab, depth is 6.2mm using the same bit lets us create a toolpath for both operations, select the Tab option and create tabs to hold in place. Text, choose a stencil font for the clock digits and once happy with the size create digits using the bitmap for guidance, I did this for all 12 digits and then deleted the original bitmap leaving us with the stencil digits.Ĭreate an 8mm hole in the centre of the piece, this is for the shaft of the quartz movement. We need to import a standard clock dial into our design, create a trace bitmap and delete the background, then highlight, combine and size to our 430mm clock face.įor the second holes create one hole 5mm and use the circular array tab and create another 59 around the perimeter. When working with MDF or with any wood, it is crucial to wear a dust mask rated for that purpose.īearing in mind that we need a circumference of 318.5mm to accommodate the LED's around the circle or face the clock face needs to be big enough for the digits to be lit up with the corresponding time.Ī diameter of 430mm was decided upon and with a depth of 6mm our set up for the dial is decided, our starting point will be from the centre of the material. Its going to be a big clock as the LED's I have left over from previous word clock projects are 60 LEDS per mtr but should space out reasonably well.Īrduino based LED's will be controlled by a Wemos D1 and it will be NTP time, no messing when it comes to daylight saving time etc(UK here)įor the clock dial and body I have some MDF off-cuts 6 and 15mm We would need to make provision for both the Quartz movement and the Electronics. LED ring clocks have the seconds counting by continuously so the design would need 60 holes, and also some way of isolating the LED's to stop spillage. ![]() With the grey matter on overtime I finally came up with a plan, I would not only make the clock an LED Ring clock, I would also make it Analogue in 2 ways, the first way would be to have a standard clock dial with the digits cut out as with a standard analogue clock dial, in theory the LED's should light up the corresponding time digits with the seconds counting around the perimeter, the 2nd analogue part would be installing a quartz movement. ![]() I was thinking of a design as I've always wanted to build one, but a design with a twist! I would like it be different to the other clocks I've seen. I've seen a few of these LED style Round/ ring clocks on Youtube etc, you know the ones, a ring of LED's which has the coloured LED's which resemble the hour, minutes and seconds, corresponding to the correct time etc.
