Good idea! In fact, couldn't you make all the arcs into rings with 'mouse bites', and then just break out the top and bottom to create the remaining arcs? On second thought, it's probably too wasteful of PCB material, so more costly. :((
No, I did not consider that because my goal was to make all arcs identical, I even wanted to make the discs identical, so when I mass produce this as kits, I could order X arcs, Y discs. Making the first two arcs as one means a new kind of part. But, it IS a good idea to help with assembly. I just need to weigh the pros and cons. Thank you for bringing it up.
@@rdyer8764 So many possibilities... I thought of putting the discs in the ring, but we need so many more arcs than discs, so it would be still wasteful.
I didn't see any major failures. Everything thing was minor. I still love the design and the concept. I can imagine one of that on my Christmas tree or maybe in my bay with a small battery. Great work!
Looking forward to the giant one :-D. Bigger parts might give you more latitude on the construction issues. Maybe a PCB board or 3d printed alignment tool would be helpful. Getting solder to stick in the right place was the issue I was having with the freeform sphere.
Hi Karl, now that I've seen it work. I'm gaining confidence in investing the time and money on a bigger version. I'm going to solder another one of this small ones using the fine tip and see if all my issue was because I was putting heat in too large of an area including the gap between the pads causing the two pads to become islands instead of being joined together. Wel'll see...
i wonder if that would just fit inside the diffuser of one of those dollar store led light bulbs, OK i'll shut-up now and finish watching the video . ( I'll send you an email later with what I mean ) Oh and try 3D printing a alignment jig , or stack and glue some laser cut wood to make a soldering alignment jig
Funny you should say that. I was inspired by Jiri Praus to make my version. Now I inspire you to make your version. Please share your progress. I'd be very interested in seeing it. Thanks Andrew!
I've been so looking forward to this video! About to watch it now. I hope your fail isn't too traumatising :-P I would definitely like to buy a kit from you once you've ironed out all the kinks. (I commented on the wrong video a second ago lol)
Hi Candee! Sorry it took so long for me to come up with these videos. I've always been impressed with UA-camrs who could crank up content faster. Yeah, I was only joking about the failure. It is not perfect yet, but it was a success!. It's not quite ready for kits, but I'm working towards that goal. How much do you think would be a fair price for a kit with the LEDs and without the LEDs? Do you think it should include an Arduino inside or let everyone connect it to their own Arduinos? I will provide sample codes for free.
@@HariWiguna I would make the kit witht he arduino optional as I would probably want to put an ESP826/ESP32 in side so I could control/programi it wirelessly (maybe even with inductive coils around the middle and make a doc for charing....hmmm... Are you going to make the cad/pcb files available? What do you use for your ED software? Kicad?
An awesome project. You may want to put two small mirrors, angled a bit to each other, behind your device so that camera can see in the reflection. I look forward to your next iteration. A great job!
Matthias, I considered that but I wanted the final version to be easily assembled by anyone who may or may not have a 3D printer. The inspiration of this project was done by Jiri Praus and he used a 3D printed jig to hold the LEDs. So it is a good idea that will work. I'm just stubborn :-)
Hi Tim! It was a scary experience, but as always very rewarding to see it working. I can't wait to build bigger ones for higher resolution animations. Thanks for the encouragements Tim!
Yes, I plan on making this available somehow, but not yet. In the current iteration, it would not be fun to build and failure rate would be high. Please be patient.
@@HariWiguna Not a problem. It just seemed with all the talk about OTHER people assembling it that you were hinting like you were going to be making a kit. But I didn't remember that you had ever specifically mentioned doing that in your previous videos. Maybe you did and I missed it. Take care. Keep on keepin' on!
With every new design, there are always iterations and errors to iron out. It's great to see your progress steps and glitches. I do hope you end up selling kits, I'd love to build and display one, maybe more.
Hi Jony, As I mention in the video, the PCB is not yet ready to be shared. It was a pain in the neck to assemble, and I don't want you guys to have to go through that. I plan on making a kit, but I probably will share some version of the files too. Thank you for your interest. Stay tuned :-)
I love the design! Have you considered making the first two arcs into a ring? I think this could help solve your initial stability issues.

Hari We need a Mega one now. Small is out, Don't you know Bigger has made a come back? :)
Oh Yeah... The plan has always to make it as large as humanly and economically possible.
I've already ordered another 1000 NeoPixels. :-)
It might be tough to assemble, but it's looking awesome Hari!
Thanks Seon! I'm hoping one more iteration and it would be easy enough for most people to assemble. Fingers crossed. :-)

Well done! Very cool resault! Now i want to make something like this too) Thank you for the great idea!

What a stunning idea. I too can't wait for the kit.
I keep thinking I will PCBway some guitar pedals but I just haven't gotten around to it.
maybe use a 3d printed jig to get it started. playing around with tolerances would probably consume a lot of time

@@HariWiguna Maybe have the Arduino as an optional add-on just in case.

Surprised you didn't hot glue /super glue the pcbs/leds in place as a holder while soldering in place.
Can't wait to see an Xmas tree covered in these!
looking great
I agree ;-) Thanks Allan!

Thanks for the encouragement and the shooting tip! I guess I CAN show all sides of the ball! Great idea!
3d print holder

need big version
It is not a fail. It is experience.
Ty Hari. Thumbs up.
Hi Tim! It was a scary experience, but as always very rewarding to see it working.

Can't wait for Part 4. Did I mis-interpret something, cuz I got the idea you're planning to sell these balls as kits.
Yes, I plan on making this available somehow, but not yet. In the current iteration, it would not be fun to build and failure rate would be high. Please be patient.

keep up!
Can you share how much the sheet of sphere parts (at 2:50) cost to make?
To be honest, I'm not sure what the actual price was. As part of the terms of the sponsorship, they provided the PCBs to me free of charge.
Great project and demo!!!
Thanks Tony!

Thanks for the encouraging words Spike! Hopefully one more iteration and it would be ready for you.
sir, pls share file gerber...thnks
so you can take his work and not give him a cent!, NO! Buy a kit.
@@Dust599 Thanks for the supportive comment Peter!
