Cleaning up Apple’s wireless Mighty Mouse - take two

Posted by tomasz in Life, Work

Many of you probably saw my previous post about cleaning up Mighty Mouse here

After using my mouse for another 2 years I have found out that using this method may in fact become less and less effective (meaning I have to do it much more often that I used to). So I had to come up with something to solve this problem too. Now I’m using a modified method which is much more material involved :-)

I bought small bottle of 91% isopropyl alcohol and I put one or two drops on the ball when mouse is still in upright position. then I use ‘Apple method’ of pushing down on the ball and turning it around to loosen up the dirt.

Then I continue with the above method using either white sheet of paper as before, or even better - clean microfiber cloth I got with my new pair of glasses recently. All that helps greatly to get the dirt off of the sensors.

After such treatment my mouse is working flawlessly for over a month now.

Winter biking

Posted by tomasz in Bike, Life

If somebody asked me a year ago what do I think about riding bike in the snow I’d say you have to be stupid to do so. Today… I did it myself and boy did I have a fun!

Bike handled surprisingly nice. Probably in greatest part because I have nice Panaracer Rampage tires. The only tricky part is when you try to turn and there is a patch of ice below the snow. Oh and rolling resistance is like you were driving on loose sand.

Can’t wait to get some more.

For those of you imperial challenged:

And of course zero clouds and clear sky. Time to look for some additional blankets…

Balanced zone controller

Posted by tomasz in HVAC Zoning, Home Improvements, Life

One of the nicest features of our new HVAC zone system is module called balanced controller. Basically it’s an algorithm calculating heat demand in every zone and opening and closing registers accordingly.

Here you can see that one of the zones (middle one) was fully open while remaining two were just barely moved, Then when this zone was satisfied in it’s heat demand it was closed and the first one was fully open to direct all hot heat into this zone to shorten furnace running time to the minimum.

I don’t have any statistic data to prove my theory yet but it seems to me that such behavior shortens greatly overall running time and simply saves us money.
