Thank you for your comment. Pipedream III installed in Ontario Science Center(http://2007.sisyphus-industries.com/art/permanent_...)is a great reference!

Thank you for your glowing review and vote !

Thank you for your inquiry. Yes, the air pump is always On. As you indicated, no opened valves for a long time supposed to affect the life-time of the pump. The pump is still operating, but additional solenoid-valve to purge air may be required as a result of further investigations.

Thank you !!Photos of assembled control circuit on front and back side are added in Step 4. They were kept on hold, because not-well-done wiring :) They may be of some help for you, but I suppose this circuit diagram is a little hard for a starter at electronics. I wish you could make your bubble clock with your experienced friends.

This Bubble Clock on this site is ver2 proto for me. Prior to this, I made ver1. Its liquid was water, not glyceline. To achieve slow rising speed, pipes were added and air is ejected into the bottom of the pipe. Before the final spec of ver1, its experience without pipes, without dividers, told me that dividers are necessary.At the early test of ver2, diameter of bubble was larger than now. Its bubbles were not spherical, becouse of the interference of the dividers. It was clear that bubbles were interfered with the dividers. Diameter of bubble is much reduced later, as you see now, so that, at this moment, the deviders may not be needed, as I said on the prior reply. If presence or absence of devider is critical for your design, how about test your design preliminarily with and withou...

Thank you for your interest to my project. Yes, my bubble clock is designed minimal to operate on my desktop.The water falls my be the "Osaka Station City Water Fountain Clock | 水の時計". Unfortunately, I've never seen it. I do not know it is still operating or not, but I really want to watch this so dynamic display!

is your advice additional video on step 7 ?tuning 8 manual valves to reduce variation of air bubble is very simple but require steady efforts : )

Thank you so much !

Thank you for your inquiry. Depending on the size of bubble comparing to the pitch of nozzles,and the height(depth) of the effective display area, the deviders may not be needed.I really look forward to see your project. Please share it with us.

I’m so glad to hear your glowing review. And thank you for your interesting suggestion. Hackaday is new for me. I will study the site and the timely contest.

Yes!! As I already replied to robot797, drifting and glowing air bubbles give me something to relax. Actual bubble clock is much prettier than the Youtube. I already become a bubble addict :)

Thank you soooooooo much!

Thank you. Following work may be similar to your idea.https://www.youtube.com/watch?time_continue=38&v=L0i-uTa4kv4&feature=emb_logo

THANK YOU SO MUCH !!!

Thank you. I designed this minimal first.If smaller stable bubble is realized, this bubble clock shall be entered in the next generation. But so high hardle for me at this moment :)

Thank you for your interest in my project.

Thank you !!

one illustrator file for laser cutter is added to Step 2.I hope this bubble clock can change in your realy unlike one digit clock : )

thank you for your comment. i may make bubble clock with multi digit or synchronized 4 units set in line. otherwise from a functional perspective as a clock, drifting bubbles give me something to relax, unlike led matrix display. i love this minimal unit, too.

I have exactly the same problem. arduino sketch, also its zip file are unable to upload. Renamed sketch file; .ino to .txt file is uploaded, but its downloaded file is not the same one, something large volume text file. Its first and second line is following. # ImageMagick pixel enumeration: 612,792,65535,rgba0,0: (65535,65535,65535,65535) #FFFFFFFFFFFF white::waiting for bug? fix.
