Discover SCUBA

A few weeks ago we had the Scouts who are going to SeaBase this summer participate in a Discover SCUBA at Dosil’s Dive Shop.  I’ve always been skeptical about the program and wondered “does anyone really get anything out of it”.  After seeing the Discover SCUBA program I’m hooked.  If you are thinking about getting certified in SCUBA diving, you really should try the Discover SCUBA.

The concerns I had with the Scouts is if they would be able to clear their ears and would they be comfortable underwater.  The program answered both questions for me.  It also lifted the boys spirits and got them excited about this summer’s trip.

The whole program took about 2 1/2 hours.  Tony, our dive instructor, took the boys through a series of drills like clearing their mask, clearing the regulator, how to surface and how to work the buoyancy compensator. After each Scout demonstrated that they could perform each of the tasks, they were allowed to go into the deep end of the pool.

In all told the Scouts were in the deep end of the pool for about 45 minutes.  They are all looking forward to the certification classes which we’re going to begin around the end of April.

Winter Solstice

We all know the Winter Solstice is the shortest day of the year, but is it really?  The Winter Solstice is when the earth’s axis is tilted the farthest away from the sun.  The actual solstice occurs just for a moment.  For 2010 the Winter Solstice is occurring on December 21st at 23:38 UTC.  so for those of us on the east coast of the US it is occurring at 18:38ET.  So the shortest day for us is December 21st.  However if you lived in Frankfurt Germany, the winter solstice occurs on December 22 at 00:38 so at shortest day is actually December 22nd. For Germany the 22nd is shorter than the 21st by less than 1 second.

Did you also know that the winter solstice changes each year?  The date actually flips between December 21st and the 22nd.  This change is due to the irregular rotation of the earth.  Next year the winter solstice occurs on December 22nd at 05:30UTC.  So in 2011, if you live on the west coast of the US, your shortest day will be December 21st, even though the winter solstice is on the 22nd.  On the west coast the exact time the winter solstice will occur is December 21, 2011 at 21:30PT.

So when is the shortest day of the year?  It depends upon where in the world you are when the Winter Solstice occurs.

I would like to give a special thanks to Andy Szarko for making me think about this on the Friday morning.

What a Summer!

This summer was a blur.

From June 26th to July 12th I was with the scouts in Philmont, New Mexico. We hiked 70 miles in the 10 we were in back country.  We did white water rafting, rock climbing, rappelling, spar pole climbing, black powered rifle shooting.  We hiked up Baldy mountain, 12,441 feet.  For 2 days we had 2 mules with us. One morning we woke up to a black bear trying to get at our food.

I ended up in India for 2 weeks on a business trip followed by a family vacation for 5 days in Maryland on the Chesapeake.

Here I am realizing that Thanksgiving is 5 weeks away.

Can someone please press the pause key?

Jet Ski Engine Bites the Dust

One of the jet skis has been having engine problems.  Initially the engine was very hard to start.  It would turnover easy enough, but wouldn’t fire.  After cleaning the carbs, the engine would start, but then it would backfire and stall.  After backfiring and stalling twice I though I  would pull the top end apart to see if something was wrong.

100_0436.jpg Well, it turned out that one piston threw a ring.  The piston and cylinder walls were torn apart pretty bad.  As you can see the left piston is a total wreck versus the new piston that is replacing it.  Fortunately the crank shaft was in great shape.    So I m now rebuilding the top end of the engine.  The engines in the skis, because of the beating they take, are designed to make top end rebuilds pretty easy.  I bought the top end kit from SBT.  Their kit includes the cylinders, pistons, rings, wrist pins, bearings and gaskets.  While I was replacing a good portion of the engine I decided to rebuild the rest of the ski.  I’ve replaced all the fuel and water lines. Putting in a new starter.  Installing new wear ring and impeller on the jet pump.

100_0438.jpgI also had a seized engine that came from my “parts” ski.  Since I was pulling one engine apart, I decided to take a shot at pulling the seized engine apart.  The one cylinder / piston came apart easily enough.  The seized piston one ended up coming out in pieces.  Once I had 1/2 of the piston removed, the rest finally pulled away from the cylinder wall and fell apart.  In the photo I have both engines with the top end off each.  With a little effort I think I can get the seized engine back together working.

100_0442.jpg100_0444.jpgOf course it is  little bothersome to see one of your favorite toys in pieces on the garage floor.  But with a little luck it’ll be back in the water shortly.

Bluetooth Headsets

I’ve been wanting to get a blue tooth stereo headset to complement the Droid.  I really like the sound quality the Droid has, but hated the dangling wires that came with the ear buds.  Wired headsets were worse, because they would slide off my head when I was in a middle of an activity.

Last month for my birthday the kids bought me the Motorola S9 headsets.  I have to say it was a great birthday present.  They work great, they sound great and they are very light weight.  There are three buttons on each side of the headphones to control music play, volume and to answer incoming calls.

When I go jogging, biking or hiking, the head set stays firmly in place.  Ever try jogging with ear buds?  Forget it, they were constantly falling out.  These headphones stay in place.  If your looking for a new toy to add to your Droid, this headset is definitely worth the money.

I’ve moved to Mocha Host

I’ve finally decided to take the plunge and host my blog elsewhere.  No longer is it on a server in my basement.  I’ve moved the site to a virtual server at Mocha Hosting. The cost alone of running the server 7×24 is about $100 per month in electric.  Where as at Mocha I’m getting a virtual Linux box with unlimited disk space and unlimited bandwidth for $4 per month.

With the move, I also had to change my domain name.  The .ws top level domain sites are a real pain to transfer.  There are alot of articles telling people that the  TLD .ws stands for “website” however it really is for the country Somoa.  As such, the registry for the .ws domains is not consistently managed.  For the my new domain, I’ve registered “thepetersen.us” domain name.  I’ll have the petersens.ws domain until June 2011.

Droid Apps

After two months of using the Droid, I thought I would review the apps that I find the most helpful and fun.  First and foremost it is a phone, I’m very happy with the quality of calls and the quality of the built-in speaker.  I configured the contacts app when I first got the phone and haven’t thought twice about it.  The voice dial app took a little bit of trial and error to find the right phrases to use to quickly get the phone numbers to come up.  Of course the voice dial app provides all sorts of examples to help you quickly figure it out, but that would require reading on my part.  RTFM – No Way!  The messaging and email apps are used through out the day.  Occasionally (once per week) I find the email app will stop communicating with Comcast.  The quick solution is the Advance Task Killer app.  This app will kill off processes running in the background that are consuming battery life while offering nothing in return.  As it kills off these background processes, it also causes the email app to fully reload the next time I open it.  This is an ok temporary solution until an update is available for the email app.  The other two apps I have residing on the middle screen is the Facebook app and The Weather Channel.  The Weather Channel app is a must have.  I’ve got five different cities entered so with three taps on the screen I can have the current weather for anyone of the cities.  One more tap and I have the 10 day forecast.

On my left screen I have music and imusic app to help organize my playlists.  I find that I use the built in music app for playback.  I also have Google Sky.  This app allows you to hold up your phone to see what stars you are looking at.  I like to take the Google Sky app at night and point it to the ground to show the kids where the Sun is currently.  I also have Astro, which provides a file manager type of screen to access the memory card.  I would have thought an app like Astro would have been included as a base app to manage the data on the phone.  To round out the left screen I also installed 10001 Cocktails.  Of course the database doesn’t include 100001 cocktails, but it has the majority of mixed drinks and cocktails one would order.  Now why would I have this app when I always just rely on the bartender?  I don’t know, but it is a fun app to have.

On the right hand screen I have the app Where.  This is a pretty cool app, but I find I don’t use it as much as I thought I would have.  I also have my prime decision making tool, “Magic Eight-ball” app installed.  The original Magic Eight-ball was undoubtedly the best decision support tool and arguably the most accurate decision support tool ever made.  I also have a quirky tech app called tricorder.  This app provides you with information like your current GPS location, the nearest cell tower and all the wifi access points that are reachable.  It also analysis the surrounding sound levels.   Usefulness of this app – none.  Fun factor – priceless.  I also have Newspaper on the right hand screen.  This app allows me to pull up news from several dozen different newspapers from around the country.

The one app that I thought had great potential, but never lived up to it….Key Ring.  This app allows you to scan all those annoying customer shopping cards.  In theory you are suppose to be able to bring the card up and just scan the phone.  In reality the food store scanners don’t like the back lit glass screens.

The one piece of functionality that I don’t use – the camera.  It takes ok pictures, but whenever the need arises for taking photos, usually I have one of the digital cameras handy.
