1. Project management

This week I have been a little bit behind schedule because of a family emergency but trying hard to catch up. I have been thinking about my project and the idea is to update an existing project my students have been doing for many years. The idea is to take an analog power supply and update it to a switch mode one. The students have been winding the transformers them selves but materials are getting expensive and hard to get. So, I have a rough idea of what I wanna do and how I´m going to do it. It ivolves many parts of the FabLab. I will make the case out of aluminum, doing it in a cnc machine. I have to make two buck converters, one for 0-30 volt adjustable output, and another one with a 5 volt fixed voltage for USB-C charging ports. There will be a arduino on the inside monitoring temperature and controlling a fan. There is also an idea floting around in my head that there will be led lights on the front. Maybe it could be RGB and controlled by the arduino also. Different things on the inside could be 3D printed or laser cut. That should cover almost anything possible in our FabLab.

Research

I have not done much research yet, but I have been looking at buck converters so I guess that´s something.

Code Example

  // the setup function runs once when you press reset or power the board
  void setup() {
    // initialize digital pin LED_BUILTIN as an output.
    pinMode(LED_BUILTIN, OUTPUT);
  }

  // the loop function runs over and over again forever
  void loop() {
    digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
    delay(1000);                       // wait for a second
    digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
    delay(1000);                       // wait for a second
  }
