• 44mm in size and 12mm in depth, fits on any wrist size.
• Dock that helps you to charge the watch and program it easily
• Have low power mode that helps the watch to last for days.
• 2 hardware buttons, both are customizable in the firmware.
• Vibration for notification.
• Wide-range of changeable watch bands.
• Scratch resistant front glass.
• 6 pin docking connector with serial and power.
• Easy to build and modify the software.
• Update the software using a mobile or PC using OTA.

Here we will discuses what you need to build one. This device is very easy to make, you don't need lots of tools and parts.

No codding skill is needed. just basic stuff like upload a code to Arduino and Little soldering skill that's all.

This equipment you will need to build the mutantW

• Good soldering Iron that at lest can go 400 degrees
• Soldering wick to remove extra solders
• Soldering wire to solder
• Soldering flux.
• Surgical knife to fix the 3D parts.

That's all.

• Only 5 piece of 3D printed parts, here is the link of the STL files that you need to print those parts :

Download link - Case. Go to the each folder and download the file format "STL" and upload them to get them printed.

You can order the Parts from the PCBway, they have excellent 3D printing service https://www.pcbway.com/setinvite.aspx?inviteid=39...

• Total 2 PCBs, go to each folder and use the file named Gerber to order the PCB.

Download link - PCB. Go to the each folder and download the files named "gerber" at the end of the file name.

You can directly order the PCB's from PCBway, total cost will be around $25 + shipping cost on where you live. Follow this link to order them, need to upload the Gerber files https://www.pcbway.com/QuickOrderOnline.aspx

Download these files and upload to the PCBWay website to get them printed and fabricated with fair price

Look at this two files that have the value of the parts with the reference number. Use the reference number to get the value/ name of the components and solder them accordingly.

watchPCB - Use excel/ spreadsheet software to ope the file.

dockPCB - Use excel/ spreadsheet software to ope the file.

Connect the dock PCB to the watch and a USB C cable, then connect the USB cable to PC. Open the Arduino IDE software in the PC and select the correct serial port and Board (esp32-s3 module) and flash the firmware.

Go to this link to download the firmware, here.

If you know how to improve the code help me out.

Follow this tips to finish the build successfully.

1. Use a tap between the display and the PCB to keep them isolated.
2. Solder the battery last
3. Use a tp4056 charging module to charge it. Set the current resistor of the module to 2k, to output 500mAh.
4. Use super glue to add the top display glass to the frame
5. Use the correct pins to charge the watch

There are tons of choice when choosing watch band and what color of the watch body you want to match the band with.

Here my one is a "navy blue" color watch body and the "black and dark blue" watch band.

And another one is a "White" color watch body and the "black and dark blue" watch band.

It's a Big project and complex one too. So i need all the help i can get.

Please help me out if you have the Skill or ability, like

• Arduino codding, to add feature in firmware
• Python, to make more useful apps, like a WiFi based Communication App to communicate with mutantC
• Let me know if you found any mistake in the guide or the supporting files.
