  • 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,[1] 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 (Ξm). (Wikipedia)

  • Really insightful on how to use the laser cutter, especially in projects based application
    Thanks Salman 🙂

    @salmanfaris best if you could point me to an example that works as described: getting different values depending on hoe close the finger is without really touching. nothing i tried did work yet

    @salmanfaris I haven't found a good sensor module for this at all. I used a thing which was calles touch sensor and it returns only 1/0. Tried to use touchRead() but it is not sensitive apparently, only 40 and 1 more or less.

    #define touch_pin_numer 33

    const int VALUE_THRESHOLD = 30;
    int TOUCH_SENSOR_VALUE;
    void setup()
    {
    Serial.begin(115200);
    delay(1000);

    }
    void loop(){
    TOUCH_SENSOR_VALUE = touchRead(touch_pin_numer);
    Serial.println(TOUCH_SENSOR_VALUE);
    if(TOUCH_SENSOR_VALUE < VALUE_THRESHOLD)
    {
    Serial.println ("Touch ON");
    }
    else{
    Serial.println ("Touch OFF");
    }
    }

    should show something between 40 (current max) and 1 (current min) the closer the finger gets but it shows 40/41/39 and 1 - nothing inbetween. got this code from the web

  • @FlorianB Can you share the code, output window/error and details of the sensor module?

    Hi! I am trying to add an capacitive sensor to the ESP32, that will work through glass with 3mm thickness and an distance of 8 to 2 cm. I have bought sensors which only work on touch, i have looked into the touchRead() function but cant get a steady value increase/decrease with distance and only a real touch gets me enough difference to count it as a "touch". I have checked Arduino examples with foil where a resistor can set the sensitivity but nothing worked on my ESP32. i have spent hours looking for an example, can somebody point me to one please?
