My Final Project
This is where I will start defining my final project idea and start to get use to the documentation process.
The idea is to build a Switch mode powersupply that can be used as a project in my school.
At first I was planing to buy the power supply itself and the students would build a couple of dc/dc converters. A adjustable one for the outputs and then another one for usb charging ports.
The plan was to include a arduino micro processor that would at least control the temperature inside the box itself. The reason for using arduino is that students are learnign to program arduino at that stage in their studies so it would fit right in to implement that into this project.
But alot of things have changed and I am currently exploring different things. It will be interesting to see where that will lead.
Block Diagram
I sat down and decided how this project would progress going forward. I thought there could be a basic program that all of my students should be able to finish but for the advanced students that work hard and finish their work early I would have to have an alternative. Ther resault was a "basic" version and an "advanced" version.
This is how my block diagram looks today.
I was looking for a long time before I found a schematic I thought would work. On the Xtronic site I finaly found one that seemed to work so I decided to try. I opened KiCad and started drawing, at the same time I started looking for components that were listed on the site.
This is the schematic I started working on.
When drawing a schematic, details matter and I made a mistake, not once, but twice. First I made a mistake with the pinout of the schottky diode resaulting in version one not working. Then, this little "VOUT" flag ended up in the wrong place, and yes, details matters.
A small but serious mistake.

Here I was trying to fix the mistakes. Still did not work.
Buck Converter Version 2.
Buck Converter Version 2.
A small mistake with the Vout flag. Once corrected, it worked very nice.
Now I can start working on the final design with suface mount components and connectors.
