LaColorduino - Your own Smartwatch how it should be

Click me for a short video demo (OLD)

Sneak-Peak with comment in GER and ENG

I build my own clone of LaMetric smartwatch but with 5 Colorduino. It will make use of an ESP8266 NodeMCU for the connection to the Internet. It's build for everyday use like showing your subscribers on YouTube, follower on Twitter, clicks on Twitch or the Weather at the moment. Even live-stats of CounterStrike: Global Offensive it's supported! What do you want more? Wait, don't say it loud, it also has a dark-mode. In the future, there is everything for everybody and everything is self-made! Maybe we can create something very big for the world?

❔ Interested? Well, read the Wiki and you will get Happy, yay.

😥 However, the Wiki isn't completed, yet. That's a hole bunch of work and I change almost everytime something about this project.

⚠ I have started to upgrade this project for ESP32-S2, the successor board, as I am quite unhappy with the core program of the ESP8266. However, I will still need a lot of time, as I am reprogramming the whole source code from scratch as well as dropping some libraries. The focus of this programming will be on the following aspects:

• Performance
• Stability
• Fail-safe
• Fully automated
• User friendliness

You can see the current programming progress here.

Preview of Watchfaces

Clock

It shows the current time downloaded from a NTP-Server every few seconds. I'll try to use the clock-cycle to lower the count of requests. Currently, it shows the time in 24h. In the future I add AM/PM mode as well. Icon isn't animated and doesn't show the current time. Maybe I update this.

Clock (day)

Clock (dark-mode)

Dark-Mode is supported which mean, it lower the light to the lowest value possible. It's very handy at night, because the icon doesn't appear and it stays at clock. (It still refreshes information in background all the time, so it can act very fast if needed.)

Indoor

Based on the BME280 sensor, it give you some information like temperature, humidity and air-pressure.

Temperature

It show the current temperature in Celsius (°C), Fahrenheit (°F) and Kelvin (K). The logo is animated. Depending on the current temperature it change it's color and the level indicator:

• Ice-Blue (Current not in use)
• Blue (T < 22°C)
• Green (22°C ≤ T < 25°C)
• Yellow (25°C ≤ T < 30°C)
• Red (30°C ≤ T)

Indoor Humidity

There is a watchface just for the current humidity.

Weather

Based on openweathermap it show the current weather at your location. It change the icon as well, depending on the weather. Here is a list which is more accurate. I did an update of all weather symbols due lack of space (reducing around 8%). However, this should match better to this Social-Gamer-Smartwatch.

YouTube

The ESP8266 get its information directly from YouTube it's self. Sometimes, it doesn't show any value after startup but I'm working on it. Library from witnessmenow aka Brian Lough found here.

Subscriber

This watchface shows how many people are subscribed to your YouTube channel.

View

It also shows you how many total views you have already. Currently, non of my counters support numbers higher than 99.999.999. I'll change this later to something more readable like 99.99M.

Comment

This one is confusing me. The official API says something about current/new comments, but that's not true. Maybe they mean new Inbox messages but I can't test this; I never get any messages 😥😋

Video

Did you know, how many videos are currently public (not uploaded)? Well, now you know it.

Twitch

Now, you reach the more important part of this Smartwatch. It gets its information directly from Twitch, same like YouTube before. In the future I try to add a Watchface which shows if you are currently online/streaming. I'm pretty sure, it looks great on camera while streaming! Library from witnessmenow aka Brian Lough found here.

Follower

This counter shows you, how many people are subscribed to your Twitch channel.

View

This watchface tells you how many views you have in total.

Twitter

Socialmedia gets more important these days. So how about a watchface as well? It works same like Twitch and YouTube before. Library from witnessmenow aka Brian Lough found here

Follower

How many people are following you.

Tweets

You are tweeting more like birds in the morning? What is this in numbers?? This one will help you.

Last Tweet Retweet

How often got your last tweet retweeted.

Last Tweet Favorite

How often got your last tweet liked.

Powermeter Watchface (Video)

You need extra hardware to make this run (ESP with Built-in button + INA226). I'll uploade the sourcecode for the second device later. However, this measuring works completly over WiFi! The Slave ESP is measuring the Voltage, Current and calculate the Power. It transmit this Information over Wi-Fi to the Social-Gamer-Smartwatch. UDP helps a lot for this use case! If you want to switch between all units, just press the button on the Slave ESP and it will change on the Smartwatch, as well. It's very easy and you can use your own measuring instead of INA226!

CounterStrike: Global Offensive

Yes my friend, it's true! It can show you your current stats as well! I just modified the official API from Valve a little. It shows you:

• Kill
• Assist
• Death
• Health (as progressbar)
• Who wins (CT or T)
• Bomb state (defused or exploded)(it override who win)

TBH, this watchface need additional script and software which I also uploaded here. Just follow the wiki. Currently, it's input-lag is at ~6 milliseconds (~166Hz) which is fast enough for such a device! It's not possible to decrease input-lag over Wi-Fi even more.

Livestats

You can change the delimiter of this watchface into one of the following character:

• Space
• Slash
• Dot
• Vertical line
• Colon
• Hyphen
• Asterix

Update-over-Air (OTA)

This one is just for the ESP8266 itself. It's not possible to update the Colorduino in this build over the air. The Icon is animated and rotating while receiving data. Based on its colour it shows you the current state (progress, succeeded, failed). Someday, if this project is finished, I make this process obsolete. Everything should be configured on a web browser. It doesn't mean I'll remove this feature, maybe it got a bugfix or an update. OTA would be very handy.
