## Strain Gauge based weight sensor (load cell)

For my group design project one of the main tasks was to determine the amount Lego blocks stacked together. The group gave me this task, so I decided to make a weight sensor based on strain gauge. Hopefully I'll be able to briefly explain how it is done and what obstacles I had to overcome.

Warning: the article turned out to be rather large

Hopefully, it will help someone out there in the world to get over frustation faster, when working with strain gauges.

Thanks hackaday for publishing my article!

## Automatic MasterMind Solver

For one of my university projects I had to find a way for automatically solving a mastermind game on a micro-controller in my case Arduino. There are several algorithms available on the internet, however most of them are very complicated or memory inefficient.

## Convert HEX to DEC in your head

Just a reminder for myself how to convert HEX to DEC and maybe backwards in my head.

## rand() strange behaviour

Today one of my equations which used rand() function from C standard library, had very strange results. My equation sometimes was more than 5% off the actual result it should be. After many attempts trying to find the problem with the equation. I thought of checking the rand() distribution. As far as I know it should be uniform.

But is it...

## QTableWidget Copy and Move single selection

In work I needed a function which will be able to copy or move the data around QTableWidget, unfortunetty for me QTableWidget doesn't have an event which will tell you which cell was dragged, and where it was dropped. After couple hours of Googling I still wasn't able to find what I was looking for, so I begun to think how can I do it my way.
