Audrey Turns Eight

Wow, we have an eight-year-old: Audrey turned 8 in early February. We had a family celebration on her actual birthday (of which it appears we took no photos!). Then we had a "friends" birthday party at Plaster Fun Time on the weekend with a collection of Audrey's school friends.

For her birthday Audrey received a couple of highly-desired (by her) gifts including a Ripstik, a radio-controlled helicopter, and a voice-activated "password diary" (it only opens when she speaks a password).

Audrey sometimes acts like she is eight going on fifteen. She constantly challenges us as parents, but that is exactly her job - to grow and push the boundaries and learn what they are. Carol and I are learning and adapting as we go. We love the journey and feel very fortunate that we always seem to see eye to eye.

The Winter That Wasn't

I'm catching up this weekend; I haven't posted since Christmas. Each of the thumbnail photos to the left will take you to a different photo album.

My photo collection was getting way too large - it exceeded 15,000 photos. Over the past few weeks I've spent many hours culling it and have it down to 8,000. I've realized I need to change my photo editing habits. Up to now I have deleted the obviously bad photos, put the obviously good ones into albums and posted them here, and done nothing with the rest. Over the long run that doesn't work. So now I'll include a few more photos than in the past in albums and delete anything that doesn't make that cut. Bottom line: you're going to see slightly more photos here (but with the same frequency of posts).

Bedtime Photo Shoot

It's been a long habit for the girls to wear Carol's nightgowns for dress up. Once in a while they adopt one and they start sleeping in it. Charlotte has done that with a black nightgown recently. On her it looks like an evening gown. One night I thought it looked so elegant that I asked to take a picture. That turned into a fashion shoot. Audrey happened to be wearing all black that day and she got in on the act with some dramatic poses of her own. She looks like a beatnik doing interpretive jazz dance.

Then, of course, they got goofy.

Plum Island

Plum Island is a barrier island less than an hour from home and includes the Parker River National Wildlife Refuge. I've been meaning to visit it since we moved here and we finally made it on one of our unseasonably warm January weekends. What finally got us there was news of an unusual snowy owl irruption this year, as well as information that many had been sighted at the Parker River Refuge.

Carol had one snowy owl pointed out to her but it was far away and it just looked like a rock to her. The rest of us didn't see any owls. But the refuge is spectacularly beautiful and we had a wonderful time exploring it. We'll definitely go back in other seasons.

We brought the "big" SLR camera with us - we haven't used it in a long time because our iphones are so much more convenient. We should take it more often because the pictures are much higher quality.

We got ice cream on the way home.

National Marionette Theater

The weekly family activity email that I receive led us last year to attend the National Marionette Theater's performance of Sleeping Beauty. We loved it and I put it on my calendar to check for this year's event. This year's performance was Pinocchio and was equally good. After the show the audience is welcome to come and take a close look at the set and the marionettes. The company consists of a father and two sons and they are wonderful with kids. At the very end, Audrey even had Pinocchio sit on her shoulder! We'll be back again next year.

The Winter That Wasn't

This album is a catchall.

So far this winter we have only received 7.8 inches of snow. The average by this time of the season is about 30 inches, and last year we had more than 70 inches by now. We've also had the second warmest November and December on record. I'm not sure about January but it was pretty warm, too. So we've spent a lot of time outdoors on the weekends and have been loving it.

It took a long time for my lungs to clear after my Christmas bout of bronchitis, so I didn't ride my bike to work during January even though the roads were clear and the temperatures mild. Two weeks ago I started, though, and have ridden most days since.

When I don't ride I take the commuter rail for a few stops and then switch to the T (the subway). From the T station, if the weather isn't nasty, I often walk to work through the Back Bay Fens, a piece of Boston's Emerald Necklace. I really like the view of the city across the Fens and I often stop to take a photo.

Last weekend our neighbors the Giuliana-Latta's invited us to join them at a community theater production of "Into the Woods". It is a Stephen Sondheim musical that weaves together several fairy tales. Everyone enjoyed it. At intermission the kids assumed it was over. We had been there an hour, so we parents just went along with it and we left. It was no reflection on the show, which was great, but we figured we'd quit while we were ahead!

If you're not familiar with Carol's hair, it is thick. The thickest I've ever seen. When it's long it has considerable weight and is difficult to tame. Carol has been tiring of it for a while and in late January she finally decided to cut it off. I think it looks fantastic!

Well, there you go. All caught up. Just in time for vacation!

Toast

As part of our morning ritual I'm the one who makes breakfast for the girls. For about a month in the fall I got creative with their toast. They looked forward to the surprise every morning.

This particular practice ended when they got bored with the media I was using and said enough of peanut butter and jam. Carol didn't feel so great about giving them Fluff for breakfast. So I was left with only Nutella to work with and my creative juices dried up. I'm sure they will reappear at some future date.

Homework-o-bot

Audrey brought home some school work she did around "inventions". Her invention is a Homework-o-bot that contains both a Math-o-maniac and a Math-o-matic. Can you tell which subject's homework gives her the biggest challenge?

My dastardly plan is working - my geekdad activities are rubbing off on Audrey!

Two-Legged Robot Walker

The Christmas list I gave to Carol contained mostly electronics hobby stuff, including a couple of servos and a Lynxmotion SSC-32 serial servo controller. The servo controller allows one to exercise complex control over multiple servos (32 of them with this board) via simple commands sent over a serial port.

So I had three available servos, a servo controller and an Arduino and I wanted to build a walking robot. Hmmm. I'd need to use one servo for each of the two legs but then I need a way to vary the traction of the legs so one can move forward on a return stroke while the other moves backwards on the power stroke. A moving weight should do it!

I didn't have any small hardware for attaching servos to stuff on hand. Nor did I have any good materials for the chassis. So I made the chassis out of cardboard in which I cut holes for the servos and I used thin steel craft wire to tie the servos in. I also used the wire to strap pencils to the servo horns as legs and as a boom to hold the swinging weight. Add a couple of rubber bands to hold the chassis in the desired shape and the electronics and batteries in place and viola: a humorous hack of a robot!

After a few minutes spent programming the Arduino to send the desired commands to the servo controller, it walked! Sort of.

It may not be pretty, but it's the first robot I've built completely from scratch.
