Raspberry Pi and Python enthusiast

I'm a tech enthusiast with 20 years of experiences with various fields of IT. Since 2012 i own a blog for supporting the wonderful Raspberry Pi microcomputers: Knight of Pi ([login to view URL]), gave Raspberry Pi/ IoT workshops and developed some prototypes. Before that, i worked with Python and web technologies (Django, WordPress and other CMS) . I also have a Diploma in Bioinformatics, but didn't work in that area after leaving university. There's a collection of my code examples for Raspberry Pi beginners on GitHub ([login to view URL]), but please keep in mind that it's mostly sample and not production code. My latest IoT/Raspberry Pi projects: * Sensor monitoring station for temperature, humidity, pressure and airflow that allows configuring the sensors and supressing alarms via touchscreen * Escape room bomb prop where the timer can be adjusted remotely * Interface for a pallet wrapper * Taking photos and videos automatically on a running track via RFID signals * Access control via keypad or RFID chip with server code validation

Automatic PDF cookbook generator built with Python. Python takes an Excel document with recipes and generates a title page, a linked index page and then goes over the recipes and creates pages for all. Good layout options thanks to the Latex which was generated by Python and then translated to PDF.

Remotely controlled bomb prop for the escaperoom of JohnDoeGames in Nances, France. The prop uses an remote Django user interface over ethernet. With that, the host can pause the prop or decide to raise or reduce the remaining time. A keypad allows the users to enter keys. The number of keys already entered is marked with LEDs. If the correct code is entered, the game is won and a green LED is lit and a sound is played.

Project for Christian Johannes B. -- 2
This Freelancer is my worst experience, and a scammer. He will purposely do a poor job and tell you that he will fix it later. So he can ask for more money as extra time. Also be aware , he's very greedy , asking for money upfront. I went dispute with him . thank God i won and get my money back. Be careful with him, very unprofessional. I will never hire him again, even for free.
