- As always we're sponsored by www.PCBWay.com.... I've finally got the modular seven-segment display working. It's been quite a journey (with a few mistakes along the way!).
I'm pretty pleased with the results - I've got a bunch more of the LED frames on order so I can add some more modules.

No need to light up all LEDs at once. You could just go through them in sequence with high enough frequency to cheat human eye.
Could you imagine how awesome this would look with a clear ito glass substrate so the segments look like they are floating!?!?
Really a beautiful design. I only wish you could make another segment design with the same base, for 38-32mm Filaments for not only less power usage (1/3), but also many different colors that are available in that size.
honestly using warm white filaments and these displays, this can make a really beautiful and classy clock, its gonna look amazing on a bland coloured wall, im definitely gonna give this a go if i can find these led filaments here.
They do look nice - I'm going to try playing around with some flexible filaments to see what's possible as well.
@@atomic14 thats a great idea, maybe even compare them to COB led strip, that might end up being intresting
This is a Fantastic Project. and Great to Follow.
Thanks!
With driving the segments a lot harder then i would multiplex them and save the current. my LED qube only drives one LED at a time and i don't notice it as it's still bright enough for day light use. in the end your be using a room heater to tell the time.
That's a good point, I'll probably end up using a PWM signal on the enable pin to tone them down a bit.
@@atomic14 i quite like the design idea and i like clocks, so it looks like i might have to order some low voltage led's. i've got a few but they are about 75V for a mains lamp i was going to make.
@@TheEmbeddedHobbyist Yeah, the 3V versions make it much more accessible - and safe!
Why not use the series-connecter higher voltage versions of the filaments? Eliminate all that trouble with ridiculous high current levels. The driver can handle 50V max, as long as your power supply is less than (LED Vf+50V) you are fine.
I did that in a previous video - th-cam.com/video/l18NYKRv0g0/w-d-xo.html - the main problem is that 50V power supplies are a bit of a pain.
the majority of segment clocks we see.... if viewed through a camera, they cycle through each of the 7 (or 8 with dot) segments, lighting one at a time. thoughts ?
Definitely an option, one of things I quite like about the current design is the power shift registers that mean you only need one IC on each module and you just clock in the pattern you want displayed. And it can sink a lot of current so you can have very bright filaments.
use multiplexing to reduce power consumption.
This is really cool! I'm glad youtube finally recommended me a new channel. How would it look if you encapsulate the segments so it diffuses the lights and becomes more visible? Or even epxoying the thing? I might have to try this someday...
Welcome to the channel - hope you enjoy it. I can definitely see some mileage in adding some kind of diffusion. I've also got some flexible filaments that I'm going to try using in a coil.
Kind of hard to read with the reflection of the plastic
Well, if u need 16amp and each dupont connector can only handle 1 amp, maybe u can just use 16 of them in parallel? Just use a longer length header?
Also why not use the 2 - wide header and right angle with alternating male and female so u dont have to use ribbon cables?
@@DataUser1357421En I wanted a bit of flexibility on the distance between the digits, in my first version I did it all on one big PCB, but that meant the digits were too close together.
Are these IDC connectors Würth WR-WTB ? i am searching for a cheaper alternative. Where did you buy them?
I used these ones - uk.rs-online.com/web/p/idc-connectors/5067042 and uk.rs-online.com/web/p/pcb-headers/7926697 certainly not the cheapest options, but I wasn't trying to optimise the price.
16A clock :D my god
Yeah, slightly over the top! As someone has pointed out I could just do one filament at a time and do it all quick enough that it looks like a solid display.
@@atomic14 i do weirdly like the sound of a 1.2jigawatt bedside clock humming by the side of me
@@atomic14 i think current i way to high check it !
@@atomic14 project is cool but power comsumpion little bit to high
Hello atomic14---Nice project. Would you happen to have the updated board files?
Thanks - I've just added them to the GitHub repo - github.com/atomic14/supersise-seven-segment/tree/main/kicad
