Giant 3D Printed 7 Segment Display Clock

- Lorraine wanted a clock for her workshop, but given she’s an element14 video content producer it wasn’t going to be any old clock! Follow Lorraine as she puts her own spin on a 3d print to create a unique timepiece you’ve never seen before. This is the first part of two videos about this clock. In the second video Lorraine will go through the different boards and the clocks potential different uses including an exercise stopwatch: bit.ly/39Zakm6

I've printed diffusers for a couple of projects using natural translucent PLA - just 2 layers thick does a nice job.

You should pin these sort of comments
Coat the inside with white paint, this way the segments will be more reflective
Love your suggestion of starting to learn any craft through meddling or modification of existing work or code. This is a great concept that needs more popularity.
Nice build! Thank you for sharing your project.
I've made a large clock and for a diffuser have used clear silicone caulk from the hardware store. Make sure it is %100 silicone.
I build a word clock, where i had to diffuse the leds, too. I used special diffusion sheets and a 4 cm distance between led and sheet. That worked really well.
I have the same China laser cutter but you can mod it to make it a lot better. I put a snap/lever switch on the lid so it cuts the laser off when lifted, a more powerful exhaust fan, and pump system with an aquarium water chiller so you don’t need a bucket full of ice water.
It's not ice water underneath. Plus it's a laser cutter from a UK company, HPC. hpclaser.co.uk/co2-laser-cutters/ls3020/
Oh I have a magnet inside that does the same - stops the laser starting with the lid open. Thanks for the tips
Nicely done!
Deeper segments to give the light a chance to spread. Then coat the inside with reflective tape to push more light out. Not done this exact thing but something similar and this is the way.
This is the way :D Too late for this build, but thanks for the tips
I think more less bright diodes with colored filters would lit those segments more even, or using concept from LCD displays by lighting edge of the plexiglas.
One of the tricks I used in a similar project for a television set I helped construct. We needed more punch and even out the reflection of the LED, I used foil tape or what HVAC technicians use to assemble duct work,. It is not duct tape. The writing on the tape comes off easily with acetone. Give it a try. It seemed to help on a very bright news set.
enviably cool workspace!
I saw someone using those white plactic disposable dinner plates once and it looked great as a diffusor...
If you make the bases deeper the surface diffuser will be further away from the LEDs, this will allow more spread and hence better diffusion.
Also, coating the inside of the base with something reflective and sideways mount them, you will likely see a better result - like many of the nanoleaf clones on youtube.
I love the designs of these. :D
The problem isn't the diffusers. You need to increase the distance. Look at how the focuser on any professional light fixture, like a leko or a spot light, works. Or how focusing of a projector works. Its done by adjusting the distance to a lens. In this case your distance is so close youre not spreading the light enough, and they are too focused on your diffusing lens. You can test this easily by just holding the lens in front of your leds and moving it back and forth.
Also, since you're using different colored plastics, your going to reflect different color wavelengths and absorb the rest of any of the scatter. Consider coating the inside wells with white or silver, or use foil. This way your reflecting back all wavelengths for maximum effect.
**edit** just read through the comments and saw these were already suggested. Probably should have done that first. I was just excited since this was a project I did last year and have in my game room. :D
@@digiassn thanks John! Can you share your project??
What's that big blue squishy thing stuck to the white board, when you used your hands to clean up the whiteboard?
I laughed at loud at this! 🤣😀
good work
instead of using white diffusion material, it will help the segments stand out if you use material that is the same color as the LEDs below
The LEDs are RGB. I know I only light them the colour of the number... But I think I'll actually colour them depending on the time of day. E.g. morning the entire clock will be blue
I haven't clicked on a element14 video since Ben left. But this is fuckin dope.I love clocks lol
Links to the ORIGINAL video/files?

It's a great concept, but the numbers aren't really visible against the background. Also, who puts the segments for '1' on the left-hand side?
I drew 1 on the right, then for some reason I coded it on the left!! The numbers are visible in the workshop, just difficult to film 😀
My thoughts exactly
@@lorrainbow I suspected it might be a lighting thing with the camera - sometimes when I'm videoing something off my monitor, I have to turn the brightness down to unnaturally low levels for it to come out fine on video, with both my face and the monitor visible :-)
You need to do two things to improve the legibility of your display, The segments need to be DEEPER to improve diffusion. Just hover a piece of your diffuser material over the LED's and raise it until you cant see the spots. That's how deep they need to be. You should be able to print some supplementary pieces to suit. Secondly the inside of your segments need to be WHITE! Internal reflections are sucking up all your light. Just some white vase mode "bun cases" should do the trick, simple. Lastly 11:00pm on a Sunday night! :-(
Use for dislpay 3d-printing remaining time.
Oo good idea! Great for longer prints
would like to change a incandescent scoreboard to a LED....is that possible?
Are these leds 12v or 5v?
These are 5v
Why not smaller to better fit the LEDs, it is not an airport sized room, and would be easier to read with lights on... I would try to put a darker transparent vinyl over the acrylic, so there is more contrast between off (currently white, reflecting too much ambient light) and on. Btw. number 1 is usually aligned to the right...
I wanted the full rainbow to appear on the backboard... and a MASSIVE clock :)
Hmmm, do you know of any frosted acrylic in darker colours? The clock looks better in real life, it's just tricky to film.
Yup, I DREW 1 on the right on the whiteboard and then I coded it on the left, oops!
@@lorrainbow I did not mean special acrylic, that may be too limiting (and possibly expensive). I would experiment with adhesive vinyl sheets/rolls, which can be found frosted (for privacy glass), smoke tinted (for car windows and headlights) etc. I did not compare with the frosted acrylic, but it offers a lot of variability and combinations...
You could try lining the inside of the base with aluminium foil
To thank you for showing me what i'm gonna do with my LEDs, take one bottle i'll pay!
The segment LEDs are barely visible
Hi, they are visible in my workshop - just difficult to film
now that you say it....I have no way of tracking time down here in this bunker....

you are so cool and beautiful. nice project. going to give it a try
A 3D printed _alpha-numeric_ display would be _far_ more useful.
What would you display?
@@lorrainbow I have an 8 character 14 segment display on my desk and my favorite part of it is that it can show MIDNIGHT when its midnight. Displaying like 1111am is also quite snazzy to look at. Downside is they only seem to be on the market in 0.54" so I'm looking at 3d printing
It should have time, date , day, if possible alarm and controler should be as cheep as possible
I hope someday I will get to work there. But it is a impossible dream. Love from Nepal
In Lorraine's basement? You could probably get some paint for your room, add some rainbows and a nice neopixel clock :)
@@Davedarko Sadly I don't own a room, anyway thanks for recommendation
@@suffering2024 sorry to hear that!
oh, the rainbow people, ....wonderful 😐
What about leaving your parent's basement and having your own place?
Haha! Man I wish my parents had a basement!
Feel free to do so Doc! Who's stopping you?
