Bangle.js Smart Watch

[Lefteris]

I'd like to take a chance and introduce a smart watch that doesn't support any kind of wheel connectivity, but i'd like to know its possible.

the

https://banglejs.com/

and as the website says

The World's first Open Source
Hackable Smart Watch

It's tech specs are low, but so it's the work that it does

Note that it supports ble technology and you need javascript to run it!

A code example :

// Draw a pattern with lines
g.clear();
for (i=0;i<64;i+=7.9) g.drawLine(0,i,i,63);
g.drawString("Hello World",30,30);

and now i'm gonna quote some text form it's spec's website

Bangle.js is an open, hackable smartwatch

You can easily install new apps from the web or develop your own using JavaScript or a graphical programming language (Blockly). All you need is a Web Browser (Chrome, Edge or Opera) and you can upload apps or write code to run on your watch wirelessly! Bangle.js is waterproof and AI enabled and comes with bluetooth low energy, GPS, a heart rate monitor, accelerometer and more.

Features⇠

• IP68 Waterproof: up to 10m underwater
• Nordic 64MHz nRF52832 ARM Cortex-M4 processor with Bluetooth LE
• 64kB RAM 512kB on-chip flash, 4MB external flash
• 1.3 inch 240x240 16 bit LCD display with 2 zone touch
• GPS/Glonass receiver (UBlox)
• Heart rate monitor
• 3 Axis Accelerometer (with Pedometer and Tap detect)
• 3 Axis Magnetometer
• Vibration motor
• 350mAh battery, 1 week standby time
• 5 x 5 x 1.7 cm case, plastic with stainless steel ring
• Can be disassembled with just 4 screws

Power Consumption⇠

• Idle, accelerometer on - 0.7mA
• BLE Connected in high bandwidth mode - 0.5mA
• Compass on - 2mA
• Heart rate monitor on - 2.5mA
• 100% CPU usage running JavaScript - 7mA
• GPS on - 30mA
• LCD on - 40mA
• Turned off - 0.08mA (0.6mA if turned off via Bootloader)

This means that when idle (in the normal power-on state) you can expect around 20 days of battery life.

Now for the last part, a question from me.

Will @Seba want to play with one of these in the future, cause it's cheap and fun?
Is there the slight chance we see EUC.world watchface on a smartwatch like this?

Thank you for your time guys
