Ahoy!

I finally got around doing my own online presentation. After some playing around with hugo I decided to put together something minimalistic and simply looking. For now I oriented myself around just the idea of posts that sometimes describe a project I made. I separate them by a projects tag. Projects added from the past (Before 2025) have a derived date from the photos or files I made back in that time. They might be actually older, but accurate enough form some sort of a timeline. ...

A current loop driven regulator. Regulates a arbitrary device with two relays. Both either connect or disconnect grid power. A deadtime between these two states ensure the regulator never activates both relays. The customer scenario included a contactor driving a industrial pipe valve in a variable manner. After a setup for the limit mapping of the valve positions to the range of a current loop (Fully closed - Fully open) => (4mA - 20mA) the regulator manages the valve and ensures a correct position accoring to the setpoint input value at all times. ...

Single Li-on cell driven powersupply. Brings regulated power to projects in a small and easily managable form factor.

A highschool project. I realized a code lock with the Arduino328P Nano board and a matrix keyboard. It let’s the user pass a code and if authorized optionally change it. Additionaly you are allowed to vary the size of the code.
