Making Unique SPINNING Watch With Arduino

- This is my experiment of trying to make a POV display that would fit on my wrist as a watch. Custom PCB with atmega32U4 and arduino bootloader powers this thing up. What do you think?

Massive round of applause of this this is the best watch I have seen in a long time and well done on the add you done for it 👏
wonderful. nicely did
wow ..u took POV to next level..☺️👌👌 keep it up👍
Fantastico, bravo, posta il progetto
Nice ! Very well done !
+Muth Pierre thanks 😊
First off, awesome project. I'm thinking about making something similar with the tlc5926/7/8 led driver/shift reg. Do the pixels look less diffused irl, they kinda seem bigger than i would expect for 0603s? Did you consider using 0402 leds?
+AnotherBrokenToaster they aren't very diffused. You can see each one quite clear. But I have tried putting tape on top and couple other stuff which made it a lot better but I didn't leave on anything permanent. The 0402 LEDs are too tiny for me to solder so I wasn't even considering those.
Thanks for the reply! I couldn't find anything about the motor and the battery, are they mounted to the pcb? I would guess that because of the on board button and the thickness of the watch.
+AnotherBrokenToaster yes they are. The motor was from an old DVD drive and the battery is just regular 150mAh li-po battery
Hi I have been looking for an answer to this. How do you program the ATMEGA32U4 before soldering it to your PCB? or you programmed it after?
How do you prototype it, in a breadboard with some adapter? or a launchpad? and after you got everything running how do you programmed the specific final MCU (ATMEGA32U4) before attaching it to your final PCB, thanks.
Bootloading and prototyping was pain in the butt. If you look at the PCB at 1:22 at the left side to the ATMEGA32U4 are couple of circles/pads which I used for programming and bootloading. I didn't use any pogo ping. I was just soldering wires there each time I wanted to program it. Desoldering them to run and debug and so on. The good thing about ATMEGA32U4 is that it's on arduino leonardo so it's well supported by arduino. This also meant I was only connecting ground and data in and out when programming and I could hook it up to USB directly.
Yesterday I was bulting this watch but I stopped because it's have got lot of vibrations. Is it anyway to decrease vibrations?
Just make sure weight of the components is evenly distributed. I have also purchased fishing weights which were small 1g lead balls that I have glued around to balance it even more.
What microcontroller are you using?
It's basically arduino uno. The ATmega32u4 has the arduino uno bootloader.
Отличная работа!!! Лайк!!!
hello, beautiful project .. you did not think to do the double-sided pcb.
I wanted to try to implement the project but the source code is missing from the rar directory.
I do not understand if it's an open source project or not.
I congratulate you again and I'm waiting for you to publish the sources to be able to do it myself.
greetings luigi
I wanted to start editing the pcb to improve some aspects .. the code is essential to understand what to touch and what not.
first I wanted to integrate a USB connector for charging and a programming connector.
add a lipo refill module and change the led resistances with multiple package to reduce the space.
the brusheless rotation motor with controller and given the flash space of the atmega implement other types of visualizations.
if you are interested in this, send me an email to predator_5@msn.com
I greet you
Thank you. Yes it's open source. I have just added the arduino code. It's a bit messy but it works. You can find it on the same link which is in description. There are some notes inside of the file. The reason I made the board single sided was because I was making it myself and it's extremely difficult to make it double sided.
I took a look at the code, it was complicated, but also some features have changed with the update of the ide of arduino.
I think you have loaded a bootloader for atmega32u4 to make it compatible with the ide of arduino. I have to remember the library to use to program the atmega .. for the rest I added to the scheme a TP4056 to charge the lithium battery. In the next days I will start to design the new pcb and if you like it I'll share it with you other inspirations.
to save space I will save the leds on a flexible pcb that I will then paste on the atmega. how long does the engine hurt what did you use?
for now I'm holding a 5volt and 0.09A gpu fan
I made a bit of confusion with the various versions of atmega32 ... I realized that you used the same chip arduino leonardo, this is positive because there are already the pins dedicated to the usb port and then you can load the bootlooader leonardo and simplify programming.
analyzing the wiring diagram and the code you have connected to the D7 pin the motor but in the diagram there is no connection .. I assume you have used a transistor as a switch to activate the current to the motor when the pin d7 is high.
+Luigi Polverino yes. You are absolutely correct. I couldn't fit the transistor on the board so it's just glued besides the motor. The motor is one I salvaged from CD drive. It was used to spin the CD.
which leds did you use?
+MisterWayne just regular 0603 orange LEDs
do you have the schematics of the project? i want to build something similar
Just because you asked :) www.thingiverse.com/thing:2522748
wow thanks :D
PCB were get
extremely awesome!, sadly, extremely inpractical
It was more of a challenge to see if I can build it.
