If you notice there is a 2 on the 10s of hours slide. You can set a flag in the software to make it use military time.

About 2 weeks. Most of that was spent refining the 3D print designs. Coding and electronics took a day each.

Here is a link to 2 versions of the code. I'm not entirely sure which one was the compiled version I previously sent you, hence the two versions. Let me know if that helps.

All 3 jumpers should be installed for 16th micro-steps.

1. Check that you are using 5V steppers. This stepper is offered in both 5V and 12V versions. You want the 5V version even though there are driven at 12V.2. Confirm you are supplying 12V to the CNC Motor Shield.3. Confirm that there are no jumpers under the Stepper Driver boards on the CNC Motor Shield. This configures them for Full Step.4. Confirm you correctly rewired the stepper motors and that connector is plugged in so the 5th position (red wire) is not connected.5. There is code in SlideClock.ino that will allow you to individually control each motor and the number of steps using the serial terminal. Press a key on a the serial terminal during startup and select the 'k - keypad control' option. This may help you debug the issue.

The GitHub does contain a binary you could download to the Arduino to at least get it working while trying to figure things out. note: the serial out expects VT100 terminal emulation, I use the PuTTY app.

RTCLib verion 1.4.1Wire doesn't show up in my Library ManagerArduino IDE 1.8.12I have Arduino M0 selected under boards. Not "Arduino SAMD 32bit Arm Cortex 0+ Boards / Arduino M0"

Others have had similar issues. There are no versions shown under the Arduino IDE. I don't know why.They way others addressed it was to download the libraries I used. Here is a link to download.https://www.dropbox.com/sh/djjzijhbkx040t0/AABl4a5...(there are zip file and the unzipped libraries, either should work).The avdweb_SAMDtimer library I used is included in the github distribution. It may also help address the issue.avdweb_SAMDtimer.cppavdweb_SAMDtimer.hLibrary management is one of the things I hate about the Arduino IDE.Let me know how it works.

Looking at your photo you have the home switches mounted incorrectly. It might work but you are losing some space along the x-axis edge.The carrier should be rotated 90* and the switches flipped over. I’ll try to take a closeup photo of mine when I get home.and just a clarification on my previous comment. You should never press enter, most input is designed to be a single key press. So that is probably why it is skipping the select one:

Orientation is correct, when viewed from the front, home and alpha are in the upper right , beta is in the lower right.The grabled characters are because the menu is setup to use VT100 terminal commands to clear the screen/etc. I use PuTTY as my terminal program and set it to VT100 emulation. If you are using the Arduino IDE terminal you will see garbled characters but it should not affect opperation.The time format is four digits and it will automatically place the colon for you. So typing 1234 without pressing the enter key should work and it will display as 12:34For initialization is should ask for Select one: 1) Tens of Hours, 2) Hours....etcType a single digit 0-4 and do not press enter. It should then display "Digit to place:", again type a single digit without pressing en…

Good to know and glad it know that is still slides well. Let me know if you need any help.

The linear bearings are 3D printed and integrated into the carriages. I originally had actual linear bearings but had tolerance issues so I just designed my own 3D printed ones and they worked great. I then realized I didn't have to have the bearings as separate components and just merged them in the carriage designs.

You need to install the RTClib from Adafruit (I used version 1.4.1)Bring up the Library Manager by pressing Ctrl-Shift-I while in the Arduino IDE. (or from the menu Sketch | Include Library | Manage Libraries...). In the search box enter 'rtclib' and then search the results for the Adafruit version and click the 'Install' button.Let me know if you have any other issues.-- Craig

Sure. What exactly is the problem you are having?

It was to make it more interesting and to have more movement when changing the time. I originally planned to have the numbers in order, but it was kind of boring when the numbers would change, the minutes would just move one number (except for when rolling over 9 to 0). By scrambling them there is a lot more motion and makes it more visually interesting.

Well luckily you have to watch it for 10 seconds every minute. LOL.I have it hanging above my workbench and when I hear it start to move I have to look up.

To make it more visually interesting and to have more movement when changing numbers. They could be order, and that was the original plan, but a friend pointed out how little movement there would be when changing the time, so mixed them up instead.

They are noticeable but not overly loud. You can hear them in the video. They could be made much quieter by changing the motors to half or quarter steps although it would slow down the speed of the slides..

I just added the Cryptic numbers to the github repository. If you choose to use the cryptic numbers you will need to print and use the cryptic bezel, it has smaller openings needed to decode the numbers.You will also have to tweak the #defines in ClockCoordinates.h for POS_0 through POS_9 to fine-tune the position of the cryptic numbers being displayed through the bezel. Every clock will be slightly different due to the mounting of the rack gear on the back of the wood. The normal numbers are much for forgiving in their positioning. Let me know if you have any questions.

I ask myself that same question. LOL.I look for projects that stimulate my mind and challenge me. That make use of my skills while allowing me to learn something new. Clocks are functional and serve a purpose. I've toyed with robot designs but have yet to find a functional purpose for one, so for now I'm channeling my energies into clocks. I have a couple more ideas and then may branch out to something else. Or maybe it's that time is something we track yet have no control over. We are like a rudderless boat on the river of time, floating to the enviable end. Tracking time gives me a sense of control even though it is uncontrollable.....nah, it's probably the first thing.

Look forward to seeing what you come up with.

I also have added the binary to the github repository so that might be another option.

Someone else had the same issue. Here is a link to the libraries I used which allowed them to compile the code. https://www.dropbox.com/sh/djjzijhbkx040t0/AABl4a5xXDFb8y1TnPWbSa96a?dl=0

I realized I may have misunderstood your original question. I thought you were asking how long would it take someone to recreate it, not how long it took me to make it.

It took me 3 months. LOL.Most of the time is going to be spent 3D printing the parts. There are 38 3D printed parts so that will probably take about a week depending upon your printer. Cutting the wood and acrylic is fairly quick, took 30 mins on the CNC and laser cutter, so probably 2 hours by hand.Assembly is a few hours, and the electronics is another couple of hours.So 3D printing time + a half day.

I figured there was no need for AM/PM unless I lived in a bunker. Analog clocks don't have AM/PM. I can look out the window and figure it out. :)A 24-hour version could be done. Would need to shift the home positions of some of the numbers to make room for the new 2 digit. There is one spot available on the right side, but would want to make it be on the left side close to it's destination. The code keeps time in 24-hour format internally and converts to 12-hour just before display, so commenting out a couple of lines will make it do 24-hour.Same issue with a 5 minute time change. There is a routine called HasAMinute passed, just need to change that to check for 5 mins changing.Those sound like exercises for the reader. :) Seriously, those changes are not something I'm going to put into m…

I forgotten them on Thingiverse and added them after your post there. Let me know if you have any other issues.BTW, where are you located?

My guess is you need to install the Adafruit_ZeroTimer library. I did this directly from Githubhttps://github.com/adafruit/Adafruit_ZeroTimerBut it looks like it can also be installed from the Arduino IDE Library Manager. https://learn.adafruit.com/pulse-room/code

Can you load other code onto the RobotDyn? If not you probably just have the wrong board type. In the Arduino IDE under Tools -> Board Type select "Arduino M0 Pro (Native USB port)"If that option does not appear then go to the top of the Board Type list and select "Boards Manager", type m0 in the search bar of the Boards Manager and install the "Arduino SAMD Boards (32-bits ARM Cortex-M0+)" package.

Just added a time lapse which shows a lot more.

Time lapse has been added

That was an early video that had a software bug that sometimes missed a change. I didn't realize that was the video I posted. Here is another one that shows it working better.https://www.youtube.com/watch?v=7FqL2aDyOcw

This is the tightest formation of the numbers possible, unless you wanted to move numbers out of the way when trying to get to a number blocked by another. the original plan was to have a frame hiding the spare numbers but several friends convinced me to show the numbers. It’s a 15 min job to add a frame so I may give it a try,

Thanks for the validation. I believe the power requirement was the reason I originally abandoned the idea (but I really can’t remember my thought process)

Sorry, an oversight. Schematic has now been uploaded.

You are the 2nd person to request that. Unless you are the same person that requested it on Reddit. All it needs is a strap. Everything is a wristwatch if you don't care how big it is. :-)

Updated, but for some reason it's not showing yet. It may take time to propagate through the Instructable's servers.It uses a servo motor that rotates a screw. The screw has very coarse threads so that a 1/2 turn will raise or lower the magnets 4mm.

There is a fourth 1, my kitten knocked it off the board and I didn't notice when I took the photos and video. I am working on a time lapse that will show all the numbers.

I have updated the Instructable in Step 3 to include details on the magnet mechanism. The images are showing up but the text is not. It may just take a little while to propagate through the system. But I also put in a support request.
