Hack Chat 0x01: Introduction to Laser Cutter
Steag Center For Smart City Technology is organizing Hack Chat regarding Laser Cutter. The Center is equipped with 150W C02 Laser cutter and Engraver,
In the session, we will look into the working principles and operation workflow the laser machine for cutting and engraving.
The Session exclusively for the Rajagiri School of Engineering & Technology students.
Date: Feb 6th 2020
Time: 5:00 PM to 5:30 PM
Venue: Steag Center For Excellence in Smart City Technologies, KE Block Extension RSET
Note: The Session exclusively for the Rajagiri School of Engineering & Technology students.
What is Laser Cutter/Engraver?
Laser cutting is a technology that uses a laser to slice materials. While typically used for industrial manufacturing applications, it is also starting to be used by schools, small businesses, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics. (Wikipedia) .
CO2 (Carbon dioxide) Laser?
The carbon dioxide laser (CO2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964, and is still one of the most useful. Carbon dioxide lasers are the highest-power continuous wave lasers that are currently available. They are also quite efficient: the ratio of output power to pump power can be as large as 20%. The CO2 laser produces a beam of infrared light with the principal wavelength bands centring on 9.4 and 10.6 micrometres (μm). (Wikipedia)

Really insightful on how to use the laser cutter, especially in projects based application
@Anudeep Thanks a lot m8, I actually made a very silly mistake of including the https:// while entering FIREBASE_HOST, where I must have entered the Domain name alone and removed the https:// extension.
Thanks again for replying that quick. Cheers.
Hello @Palani, In the Firebase, there are two types of storage,Cloud Firestore (Very recent one & NoSQL database) Realtime Database (To which we upload the data using NodeMCU)
In the Arduino Code, you can see that there is a variable named FIREBASE_AUTH.
This variable should be assigned to the Database secret. This you can find in Project Settings -> Service accounts -> Database Secrets.
My mistake is, i have mistakenly assigned thay to Web API key. This is found at Project Settings -> General.
The error can also occur when u don't initialise a proper realtime database in Firebase. (This is not my case).
@Anudeep Hello Anudeep could you please help me out by elaborating the fix to get rid of that error?
Thanks in advance.

Applications must be submitted through their dedicated application portal which opens on August 20th, 2020 and will close on September 20th, 2020, 5 pm India time.
Application deadline: September 20th, 2020, 5 pm India time.
@kowshik1729 If you are using an external high-speed switch, there is only one one clock generator for both wifi and BLE and the high-speed switch you mentioned is Ultra-Wideband (UWB) 3–8 GHz from its datasheet
you also check this solution that I shared in the previous post.
There is a special option called “Software controls WiFi/ Bluetooth coexistence” it can control the ESP32's Bluetooth and Wi-Fi coexistence using software, more details: https://www.espressif.com/sites/default/files/documentation/ESP32_FAQs__EN.pdf
