When eating a salad, it’s always nice to have some herbs to go with it. However, to get those herbs, they first have to grow. And to grow they need… You guessed it, water. Watering isn’t everyones strongest point. It isn’t mine either. That’s how I’ve come up with the idea to create an automated…
Wireless-Multisensor
After years of using Home Assistant with power hungry ESP’s and the desire to create battery powered sensor modules, I started thinking about alternatives. I had one ATtiny85 laying around and after a quick look in the datasheet I figured this microcontroller would be perfect! First of all, I started thinking about functionalities; that’s always…
Ball Balancing
During the last block of the second year we had the subject Measure, Regulate & Control. This subject was about capacitance, coils, system equations, motors, Fourier Transforms and that kind of stuff. Nothing I haven’t learned during the projects listed on this website. However, luckily we also discussed PID-Loops; I think they are awesome so…
Taguino
Here is a new project again! This time, it’s a lasergame project. They’re fun to play, so also to make! This project has been made with four other people from college. At first sight it doesn’t look like this is a very complex project. However, a Realtime Operating System is used. This RTOS is ran…
Convector Radiator
Since my Home Assistant installation has become pretty filled I wanted to add something new to make it even more capable. The first thing that came to my mind was my little project list in my notes somewhere. The first item was to build a convector radiator. So that’s what I did! A convector radiator…
Portable Radio
A couple of weeks ago, I decided to build a Portable Radio as IPASS project. This includes using HWlib, which is written by a teacher, and writing every other piece of code needed. The written libraries include libraries for the following chips. TEA5767 RDA5807M DS3231 24CXX I2C EEPROM Rotary encoders The title also tells it’s…
Finite State Tamagotchi
It’s just what the title says; a Tamagotchi. The only difference is that this one is designed by me! It’s designed from the ground up. The idea was to use a Tamagotchi that’s happy when it’s standing up right and it has company. Thus, we need the following. RCWL-0516 Radar Sensor Tilt sensor Arduino Consequently,…
CareBot
Carebot is a robot based on a BrickPi that can do all kinds of interesting and useful stuff. It’s supposed to be for a hospital-environment. The initial goal was to follow a line with high contrast against the ground. We thought this wasn’t very easy to implement in hospitals so we challenged ourselves to come…
DosiMate
Dosimate is a device that’s supposed to be like a smartwatch that’s specifically suited for Parkinson Patients. It has an intuitive UI with as little rings and bells as possible. It is only possible to turn and press the knob, nothing else. Its small form factor makes it possible for nurses and doctors to monitor…
