Hans has, as hobby projects, developed web apps, flash applications and done microprocessor programming.
He has used coding languages and techniques such as Mainframe BASIC, MacBASIC, Actionscript, PHP, HTML, CSS, XML and Javascript.
This page describes the projects.
During high-school year 1975, Hans has access to a mainframe computer through a TTY terminal at Bezeliusskolan in Linköping.
He writes a program that calculates how to bet in roulette in order to win. The algoritm is based on that the person betting has an unlimited resource of money.
The program is stored on punch tape.

Hans uses C to create source code that is compiled for PIC-processors.
The DCF Simulator is a hardware device that can set radio-controlled clocks to any date and time. It has 3 PIC-processors for different tasks running compiled code, coded in C.
The source code is compiled using the CC5X C Compiler.

Hans uses HTML, CSS and Javascript to create web applications that a run in the client browser.
Optical Morse code signalling is a web app written as a single HTML page with Javascript and CSS, with one additional "About" file.
The application simulates the type of signalling Hans performed during his service in the Swedish Navy. Some characteristics:
