My name is Kalle Hyvönen and I’m an electronics enthusiast from Finland. I’ve been interested in electronics, technology and programming for all my life. I was born in 1988 and since then I’ve always been involved with electronics.

At first it was dismantling of all kinds of electronic devices (including a disposable camera and getting zapped by the 350v capacitor inside when I was around 10 years old) and later building devices of all kinds mainly for fun. I also tend to suffer from polyprojectitis meaning I have a lot of projects but none of them seem to get finished… My topics of interest range widely from power electronics (induction heaters, tesla coils…) to low power microcontroller circuits. My other interests include photography, cycling, cooking and growing chilies.
