When soldering the LEDs you add more weight with more solder, therefore reducing the leg count and also the pad size will be helpful. It was a good choice to pick RGB LEDs, since they have common Anode or Cathode, which saved 2 legs and 2 pads for every 3 diodes. I have used similar LEDs in the past and was not happy with them at all. They were very sensitive to high temperature and were bending in the soldering process. Another downfall on them was the way you see the 3 individual diodes when lit. But mine were by Everlight and yours are by Citizen, presumably better. I'm looking forward to seeing how do you like those.
This stuff is inspiring. Keep up the good work!
Watching what you're doing with the flexible PCB is amazing.
This is very cool.
Damn impressive! It was very cool watching from whiteboard to pcb... looking forward to seeing the finished product!
Glade you like it! That is sort of how I design every project I make so I had to capture that engineering vibe
I'm really excited about the next video!!! Such an awesome idea
Man,
You're a genius. Great work done. Keep up the good work.
I would suggest smt conductive adhesive in place of solder to leds and/or underfill/encapsulant. You might also stagger leds top & bottom along edge to stiffen that edge in the next revision. That would also up you side to side resolution at a cost of the bottom leds being off at bottom of stroke & top leds off at top of stroke. You could also try just a thin strip of very thin fr4 in that area in the next design. Alternatively you could 3d print a thin stiffener for that area. Just some things to try.
Looking impressive! Both the design and your datasheet surfing skills!
Thanks! 😊
Very nice! Can't wait for the continuation.
This was just amazing to watch. Beautiful work!
Glad you like it! My idea for this video was to try and log the design process from start to finish 😊
More flexible youtube electronic channel. Great videos!!
Great skills, so much work also i. The filming editing. Thank you! Subbed
Amazing as ever. I would love to have a narrated version of that montage in the middle of the video.
Thanks! Routing the pcb was a long process so I had to speed things up haha
Your work got me into electromagnets! I'm not gonna lie: most of this stuff is black magic (although its probably just the algebra) and I'm learning slowly. Just managed to drive an electromagnet(nail and wire) using one of the L293Ds in my arduino kit (surprising how versatile these things can be with some imagination) and reversing the polarity with a pushbutton makes me feel like a bit of a wizard! You should make a video about designing your pcb coils: with chinese pcbs being dime a dozen these days I feel like people would find all sorts of cool uses for them (myself included... maybe)
You should check out the Peachy Printer design. I think your PCB coils would make that concept even more elegant.
👍 I think flapping mirrors can be done using this technique - depending on their size
This is awesome
great work carl !!
Hey, did you try with w small oled or TFT sized 128x32 or 128x64 they are not expensive and well shaped for this kind of experiment. It may display better pov resolution than usual led, providing a lot more pixels and more transparency effect
compared to LEDs
incredible flex dude
You are great ! Love your videos
very good project. !! can't wait for next video :)
Great Idea 👍
What software is used to work on pcb here? Do i need learn any software beside phython?
Very cool idea
What about keeping the led fixed and moving the display with mirrors on the flex like a dlp projector?
good design
Agreed I can't wait to see it in action.
great !!!, I can't believe you don't have many more subscribers
Amazing ! Beutiful work ! Keep it up !
Thanks!
You should try a coil for every led
Wow, you're amazing!
Great job!!!! You need more monitors for work with Altium Designer
Haha thanks! 😂
have you thought about using LEDs with built-in driver, such as WS2812 etc.? they require only 3 wires (Vcc, GND, D) and shouldn't weight much more than RGB 4pin LEDs I think.
It's package is a little bit bulky and not in a right-angle package.. I 'm not sure if there are right-angled leds with built in drivers
@@CarlBugeja oh right, I didn't realize you need them at right angles. Anyhow, looking forward to the next video!
You can get side emitting SK6812 LEDs in 4020 package. Could be a solution of you want more LEDs but don't have space for more tracks.
@@CarlBugeja SK6812-SIDE, but still a bit bulky and possibly too slow refresh rate for POV. You can however mount APA102-2020 on the edge of rigid PCB so it points sideways...
Which software is it btw
Inspiring
Wow
Great job Carl thanks for sharing this with us
Hey Carl try to take a look on this 4x4 QFN led driver IS31FL3235
Thanks! Looks like it's also suitable driver!
I wish i could buy the flexled
I don't understand. Wouldn't adding weight make it easier to drive with larger deflection? Just give it a twang and measure it's natural period and drive it near resonance?
This was made into bitzee ... cool toy
i need schematic please
