Thank you for your highest compliment for me !Yes, I will.

Thank you for your interest to Bubble Clock.AilExpress often changes links. I suppose you can search using some of the keywords mentioned on Step 1. Solenoid valve: "DC 6V” "Electric Mini Micro Solenoid Valve" “Air" "normal-close 2-way solenoid valve”I’m looking forward to see your Bubble Clock.

Thank you for your interest to mag?CUBE.Little children often continue to construct and deconstruct again and again and again : )

Thank you for your comment and good question.Your inquiry the 4 slots in "the jig pieces” suppose to be "the magnet case” set on the jig of the first photo on step3. If it is right, the 4 slots around the center hole prevents adhesive from oozing into the center hole. I want to reduce the risk for the magnet fixed in the case by the oozed adhesive. Please inqure me if this is a misunderstanding reply.

thank you for your continued interest to my bubble clocks !!!

I have made bubble clock ver3 which can display four digits at onece with some additional functions. you may be interested in it.https://youtu.be/T5LQQ5ZNU9s

Thank you for sharing your experience.This bubble clock using glycerin is ver.2 for me. Liquid of ver1 is water, and bubbles are ejected into pipe OD10mm ID 7mm to reduce its rising speed. You can see my ver1 here: https://youtu.be/wpaDbDAH25UI've never tried such a thin pipe.Rising speed of bubble in high purity glycerin is slow enough to see. So that, my ver2 has no pipe, but divider plates "separater"s are added. You may already tried, how about "separater", not pipe, made from acrylic board 1mm thickness. "separater" set with 5mm spacing can be the same width using OD 6mm pipes.I want to see your smaller bubble display.

Thickness and color of acrylic board information are added to the caption on the picture Step2. Only the "solenoid-valve & air branch pipe support" is made of thickness 3mm.My instruction is improved by your inquiries. Thank you!

Thank you!

Thank you for your interest.The attached laser cut data on Step2 is created by adobe illustrator and each parts are drawn on different layers. I have tried to save as SVG file by illustrator, but its not saved as the same size as original on my mac.dxf file is correctly saved but unfortunately could not upload it with error message from instructables.com. I have revised the data file not overlap each parts drawings.I really look forward to see your bubble clock !

Thank you.I am investigating that four synchronized units in a row, or four times as many injection nozzles in a vessel, or .... (^ ^)

Many thanks !

Thank you. I'm looking forward to see your air bubble screen.

Thank you for your interest to my projct !

I would like to know the same question what does Premium Membership mean.Unfortunately the following link in the past reply is not active. Can you inform me the revised link?These are the benefits: https://www.instructables.com/account/gopro

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 without …

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!

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.

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 : )

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 :)

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.

Thank you so much. Comparing to ver1 model using water, refractive index of glycerin used for this ver2 is much higher. So that, I searched a rectangular-like glass vase, but suitable size one was not found.This minimal bubble clock has only 20cm height x 10width effective display area, its next expansion ether vertical or horizontal or both or multi units or ... At any rate, watertight and esthetic acrylic tank to achieve maximum display area and minimum glycerin is required, I may try. : )

Thank you so much for your interest to my project. Unfortunately, I cannot meet your requet, now. I shared this instructable looking forward to seeing members' bubble clocks including you : )

Thank you so...so much. Not yet the scream reached to me : ) I'm not familiar with how such thing can be done.....Please confirm Step 1: the additional information on manifold. It is not a supecial but common part in aquarium field, i suppose.Thank you, needfulthing.

Thank you soooooooo much!

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.
