  • I made couple of bass tramps tuned to the room’s main resonant frequencies, which I measured. I followed instructions from the book.

    I added sound absorber panels to the walls and ceiling to kill immediate reflections from the main speakers plus a sprinkling of additional panels to kill reflections and also act as decoration. I also needed to move one radiator because it was in the worst possible location for my setup.

    The room got thick curtains to improve absorption, and they also darken the room as it is dual use music listening and home cinema room. A few defraction elements went into the ceiling for a good measure. The ceiling is made of custom panels that I made myself from wood and fabric to allow sound energy through to the various acoustic elements behind them.

    I also spent a fair amount of time with subwoofer placement, but in the end it became a bit of a compromise between sound and placement of furniture. Nothing a bit of signal processing can’t deal with, mind.



  • The story of Nokia the company is long and meandering. Its roots go back to late 1860’s in the town of Nokia in Southern Finland, near the city of Tampere, from where they’ve gone through all sorts of businesses, including rubber boots and industrial capacitors to name just two. You might even find an old Nokia TV knocking about. The mobile handsets phase was in some sense but a blip in the story, although a spectacular one. I’m sure they’ll keep going in one way or another for a fair while still.













  • All important automations should run fully locally. I also find that focused and simple automations are often most useful. When I say simple I mean in terms of automation logic, not necessarily in terms of interfacing devices, which can be tricky at times. Example of simple automations I like most would be switching amplifiers on/off based on audio state changes, switching lights on/off relative to sunset, and switching electric water and floor heating elements on/off depending on energy price.


  • My introduction to the internet was way before www. As a first year student I mentioned a topic I was interested in to a professor. He said I should email his friend at University of California, Berkeley as he would know about the topic. He gave the address and I went away to find out what this email thing is. The next morning I had a reply. For a farm boy for whom snail mail and telephone were the means of interaction beyond the neighbours this was totally mind blowing. I got advice from a professor in one of the top universities in the world just by emailing him!
