This old post is getting lots of comments and no replies from my side and I am sorry for that. I’ve limited my time and energy to the support section of the community forum lately because it was our no. 1 priority and I was struggling with finding enough time to cover all the other posts you folks were making on the forum (A lot of things had happened lately and you know that already - registering the company, dropping out of college, moving the company to a bigger workplace etc.).
The story about this watch didn’t stop at that prototype. In fact, the watch was designed for a soldering workshop that was held on a Maker summer camp in a Kraljevica - a coastal city in Croatia where there is a maker-culture center partly financed by the government.
Why was I doing this in this super-busy and stressful time of the year and didn’t focus on the MAKERbuino and other important stuff
- because I’ve promised them to design a simple kit and organize workshops almost 8 months before and they didn’t have anyone else to do that job instead of me when I tried to cancel the workshops.
Anyways, the watch was successfully soldered by 120 primary school children and despite me being super-late with everything (not just with MAKERbuino-related things) and totally stressed out, everything turned out quite nicely.
You can see from the pictures above that the kids were also making this tiny wooden box with a round opening. That is a LIR2032 battery charger they were also assembling. Yes, the watches came with a rechargeable battery and a charger for the battery because the LED’s drain the watch’s battery pretty quickly (you can check the time for approx. 200 - 250 time and that was enough for 2 days of power-on time for some users that were clicking their watches every 10 minutes).
You can find the watch’s schematics here:
And the code here:
Besides those watches, the kids were making some other cool project in the 10-day workshops too - they were modeling fidget spinners and making wooden hydraulic robot hands:
And there was also a group of 20 high-schoolers that had to make a special project.
That special project was the MAKERphone - a fully functional mobile phone I was building with the high-schoolers.
It doesn’t even have a PCB, MAKERphone is just a bunch of modules inside a wooden box, but it works! It can actually make and receive phone calls.
You can find more about the Maker camp at their Facebook page here:
Last year I was also in charge of a soldering/coding workshop where I was making self-balancing robots with 20 high-schoolers.
About the future of MAKERwatch:
I do realize that this is not a super-original or super-complicated project. It was designed with a purpose of making a simple soldering kit for children, learners, and tinkerers to learn to solder whilst still having a final product that has an actual purpose - showing time.
Besides just buzzing and showing time, I’ve thought of some fun functions that can be implemented in the watch
- showing time in binary or hexadecimal modes
- pronouncing time with the “Talkie” Arduino library https://github.com/going-digital/Talkie
- saving and playing a bunch of RTTL melodies: https://github.com/ponty/arduino-rtttl-player
- saving and displaying a bunch of text messages (still limited by not being able to display all letters with basic 7-segment displays
- adding a temperature sensor (there are still some GPIOs left)
- alarms, timers, stopwatch (can easily be implemented with the existing hardware)
I’ve got approx. 80 MAKERwatch kits left from the workshops and will soon put them in the shop where you’ll be able to get them, test them and tell me what you think.
You will be notified first when that happens.
As you can see, I have loads of ideas for future projects and Kickstarter campaigns, but time is the greatest limitation
MAKERbuino is still our no. 1 priority and takes most of my (our) time and still needs lots of work and improvements, especially regarding the documentation and tutorials.
Tell me what you folks think!
