A new page about the Mossala and Ava craters in the archipelago of Turku in SW Finland.
Updated Mars 13. 2012.
I am a physicist living in the archipelago of Espoo about 20 km from Helsinki the capital of Finland. I am married and live with my wife, my doughter, two dogs and two cats at the seaside on an island called Bergö.
I have always been interested in music, playing the violine, guitar and a strange medeival instrument a keyed fiddle (in swedish Nyckelharpa). Other interests have been computers and automatic measurement systems. Presently I am working at the Ericsson telecom company. Electronics has also been a big interest of mine, but mainly due to the fact that it is easier to get a program working than planning and building a complicated electronic project, I have built fairly few big electronics projects. A new appoach is to use microcontrollers like the PIC16C84 to replace complicated discrete logic. When I initially started playing with the PIC processor there was no useful high level language compiler awailable. I figured out that a simple language supporting basic control structures like IF ... THEN ... ELSE, WHILE and REPEAT ... UNTIL should be a fairly small project to complete. The reality was that it was easy but at the same time I wanted more from the compiler. The program fairly fast grew into a real language very loosely based on PASCAL/MODULA-2/BASIC. The main point in planning the language has been to make it self documenting and easy to read. I call the language SIL. The present version is 0.53 but I feel that the language is usable and there are seldom any need to patch anything (programs normally compile cleanly). The most recent version supports PIC16C71, PIC16C73 and PIC16C74 in addition to the PIC16C84.
A nyckelharpa is a violin like instrument with a keyboard and a large number of resonance strings. More information about the nyckelharpa is found at American Nyckelharpa association or at Eric Sahlström Institute
The picture shows the very primitive temporary shed under which the boat is built. Building in an unheated shed essentially outdoors means that the building period in our climate is from the end of april to the end of september. Using epoxy glue is restricted even more because I feel the temperature should be above 15 deg C to ensure proper hardening of epoxy. Polyurethane glues on the other hand seem to work well even close to freezing temperatures. The glue seem to be harder the lower the temperature is.
This picture shows the house seen from the rear. The roof beams are put temporarily in place to give a hint of the form of the roof. The height of the house sides has to be changed significantly when the roof is made. The present plans are to build the roof using thin tongue and groove wainscoting covered by two layers of thin 4 mm plywood. The tongue and groove wooden roof should look very nice and traditional from the inside with the plywood ensuring there are no leeks.
