So we’re finally done with that daylight saving nonsense, meaning we get more light in the morning but less in the evening – "less in the evening" of course meaning "dark when I leave work".  I rode home last week once at about 9 (would be 8 this week) and had pretty good visibility with my handlebar-mounted CatEye light, plus a flashing red light on my back.  Yesterday we stopped at REI and I picked up two new flashers with the intention of attaching them to my helmet – the highest point of visibility on me.  Plus, with a head-mounted front light I can look at something I want to see and get it lit, the bike light only goes straight forward.  Also I can look right at cars and be (more) sure they can see me, since I’ll be shining it right into their heated killing machine.

My 10-minutes-before-I-leave-what-can-I-rig-up attempt resulted in this cyborg monstrosity.  Aw, yeah.  That really is a piece of wood attached to the helmet with zip ties.  Jealous much?

My plan for tomorrow is to remove all of that and rig up some amazing magnet system to be able to clip the pieces on and off easily and reduce the overall weight.  Also, I read a lot about helmets today and realized quickly how potentially dangerous it is to have a big stick attached to your head — the helmet’s supposed to slide on the pavement if you crash, not dig in!  So, quick disconnect magnets to the rescue!  Stay tuned for more build pictures.

( Too bad, tho, that cyborg head looks pretty freaking cool when I’m barreling down the path.  Like I have a laser canon on my head.  Hmmm, laser canon… )

Took a quick trip to Chicago last weekend for a super-fun Halloween party: Heaven and Hell(icious)!  Now that Laurel and Freddie live upstairs from my usual Chicago destination, they decided to throw a joint party and decorate the downstairs like a creepy idea of hell and the upstairs like heaven.  It was awesome!  Not sure you can see the amount of detail that went into heaven, but they laid down white paper on the floor (looked good and protected against spills), hung blue plastic on the walls, blew up a million balloons, hung streamers, and even printed a ton of gorgeous cloud pictures to put on the walls!!  No idea who these people are but it shows some of the decorations…

Karen and I went as a portable (pirate!) bar, and won in the informal costume contest!  Who could resist a working tap and snack vending machine??  No one.  (You can’t see it, but Karen has a three-compartment snack vending machine like you see in grocery stores.  I rigged it so it was free, and we filled it with bar snacks!)

Laurel dressed up as Sally from Nightmare Before Christmas — including a hand-stitched patchwork dress!  Whoa.  Clearly the costume judges were being nice to their out-of-town guests to have overlooked her…  :)

Cody brought back out his creepy baby outfit.  Creepy.  Karen let him rest on her bar.

A great time (and much pumpkin ale) was had by all!  Happy Halloween!

That’s how I did in the beer identification last night at Town Hall’s Beerlympics: 1 correct answer out of 6 beers.  What.  The.  Hell.  I don’t know, I’m still trying to come up with an excuse.  Terrible.  The winner got just three, and I think he got the two I was pretty sure about but got the name wrong on one and sort of got mislead by the Belgian yeast in the other.  Talking to the brewer afterwards he said it was the same yeast as the one I guessed, and hell, it tasted the same to me.  Then there’s one I really have no excuse for, should have nailed it, which would have given me 4!  But did I get 4?  No.  Guess I’ll just have to go to Town Hall more this year to "practice".  :)

We got third place overall, though!  Cody was DQed in the chugging cause he has a leaky mouth – they thought he dribbled too much, even though it was just a few drops.  Boo.  He had the fastest time, too…  Scott was amazing in the quarter bounce – he found his rhythm and I think had 10 in a row at one point!

But I have to find a new word to describe the awe in which I now hold the eating machine named Peter: 5 brats in 5 minutes.  I’m talking big, greasy brats and buns, none of this little hot dog stuff.  Unreal.  I’m wishing someone had a video phone and I could go find a clip on Youtube of him tearing his shirt off after brat #3.  Oh, my.  First place in the brat eating contest!!

In other news:

• The wakeup system is moving along nicely.  I found a way to remove the optical sensor piece and am instead monitoring the voltage directly, which gives me a much more reliable (and faster) way to sense when the alarm is going off.  We’ve had it in our room this last week with just a few LED lights instead of the final fixture (the kit for that dimmer just arrived yesterday), and it’s been working pretty well.  I think it will be better once it’s generating more light, and once I stop waking up early every morning wondering if it’s going off soon.  Should be fully operational by next week when I’ll try to document it better!
• This is probably officially the latest in the year I’ve been continuously biking to work, and it rules.  There were a ton of birds singing yesterday along the Greenway, the weather’s been chilly gorgeous, and I even saw a deer last week!  I’m feeling more and more confident that if the route is ridable the cold is something I can handle with good gear.  And my definition of "ridable" is getting broader, so here’s hoping for a good winter of bike commuting!

That’s all for now!  Karen and Cody and I are heading to Chicago this weekend for a halloween party, should be a blast!

(sorry, I don’t know what sort of gang sign I was going for there, but it just looks like I’m hugging myself…)

Argh!  So close!  Last night was the first night I tried to test the new wakeup system (it feels weird to call it an alarm, but wakeup system is too long..?) and it went pretty well – until morning, that is.  Then, as planned, there were birds twittering nicely, but the room remained sadly dark.  And, totally ruining the intended effect, I was thinking about it all night and kept waking up to see what time it was and when it was supposed to go off!

So, clearly not working yet.  Let’s back up…  I ended up with a Sony ICF-CD815 Dream Machine CD / radio alarm clock, a nice looking unit with dual alarms.  I can imagine a scenario where one of us has to get up at some terrible hour, and can use one built-in alarm, leaving the second one to trigger the system later for a gentle wakeup.

Speaking of "trigger the system", that’s where my troubles began:  I needed a way to tell the Arduino that the alarm was going off.  I had toyed with the idea of watching voltage across the CD motor, etc, but ruled this out because we’d never be able to play CDs in the room without starting up the light dimmer!  After pulling apart and testing everything I could think to test with just a multimeter (if I keep doing this I’m getting an oscilloscope), I decided to tie into the LED for Alarm A.  By attaching my own light here, I could create a signal outside the clock that I hoped I could detect with the Arduino.

It wasn’t that easy.  The light can be either solid on or solid off depending on if the alarm is set or not, and it goes to a "flashing" state when the alarm is actually going off.  Hmm.  I wrote and tested numerous versions of code to watch for resistance changes in a light-sensitive resistor, and went to bed believing I had it nailed.

The complication lies in the poor sampling ability of the resistor (that pulse line above is actually pretty wavy) and the timing issue of the blinks: no matter what I tried, the code would sometimes miss a blink, and decide the alarm was over.  What I ended up doing was keeping track of the last 8 samples and counting state changes.  If I could say that the light "changed" (beyond a certain threshold) at least 3 times out of 8, it was "blinking".  This leads to a little bit of lag – 8 samples takes about 5 seconds – but it seems to be working.

… of course, I didn’t get that sample size right until too late.  This morning some combination of being in the dark and possibly a loose connector left the whole thing inoperable.  Dag.  Always tomorrow morning, I guess!

At right: the little guy making it all happen.  (The Arduino board is actually under the piece you can see.)  The three clear LEDs are for temporary lighting, the red one represents the furnace until I run that wire, and the buzzer is for the backup alarm.  That blue-tape-wrapped thingy on the top is the Alarm A LED glued to a photoresistor for sample the alarm light.  Once I get it finalized I’ll put it all on a new circuit board and in a nice box.  Also still waiting for the final dimmer kit to arrive…  Fun!

(oh, and there’s an output pin standing by to fire the coffee pot in version 2…  :)

First, Eric posted some wedding pictures to his flickr page, including what might be the best dance picture ever.  Also here’s a link to Freddie’s pictures from the weekend, check them out if you haven’t already.

Second, time for a long-overdue post about the party and fundraiser at Town Hall!  Karen had this great idea about wanting to be able to wear her wedding dress for other occasions, and after a little dye-job by yours truly, it ended up being absolutely gorgeous!  Most importantly, it matched the dress that Ophelia was wearing…

We had decided to have a raffle for fabulous prizes and send the money via SMA to help our friend Alfreda with her schooling in Ghana.  Steve helped get some pictures for the poster, and Alfreda had time to email us a nice letter that we incorporated.  It came out very slick looking and the raffle was a great success!

We posed for a picture for Alfreda and Samuel: lookin’ good…

Fabulous prizes!

You can see how excited everyone was with their winnings – and for a great cause!

Madeline can’t believe their luck – or was it rigged??

… after all, that’s their baby picking the winning tickets!!  Hmm…

(Official disclaimer: Baby Francis was an unwitting participant in the alleged "rigging".  As in most child cases, the blame lies with the parents.)

Nate and Joe compare beards.  I think he’s winning, but it’s close.

All told, a great party!  It was wonderful to see so many friends we weren’t able to squeeze in on the North Shore, and celebrate in a more informal environment.

Stay tuned for more Town Hall pics next week as Nate, Cody, Peter, and Scott prepare to enter the Beerlympics!!

I’m sure you’ve all experienced this: waking a half-hour before your alarm, alert and ready, but decided to sleep the extra half hour.  When the alarm goes off you find yourself back in REM sleep and can barely open your eyes.  Or, like this morning for me, the heat comes on and the temperature change causes you to wake up too early.

Ever since moving north, I’ve been looking for an answer to waking up in the dark and trying to convince my body it’s actually time to get up.  Last fall I researched a number of products, include the DayBreak Duo Sunrise Simulator, the Soleil Sun Alarm, and the Progression Wake Up Clock.  They all look intriguing but are either pricey, ugly, or both, and none offer the full set of features I’m dreaming of.  Recently my coworker pointed me to an article about a guy using an Arduino to control the temperature in his kegerator, and it got me thinking…

The human body responds to light and heat to come out of deep sleep and into an alert waking state.  Surely there’s a way to combine all of these into a cohesive and natural wakeup system??

Wish List

• must be easy to set the alarm, no tricky knobs or interface
• has to fade a light on over an adjustable period of time
• must have an option for external lights
• play birdsong and morning sounds, also faded in
• have an actual "alarm" sound if not deactivated
• flash lights if not deactivated
• tie into the thermostat to bring the heat on
• must be separate from the programmable thermostat so we can adjust the wakeup time without reprogramming
• has to make me coffee!

My current plan is to find a cheapish CD player alarm clock, and hack the guts of it to find a way to tell the controller the alarm is "on", or going off.  This may end up being the hardest part of the project, but I’m hoping that with the CD circuitry there will be a pretty obvious change I can monitor, maybe voltage across the motor?

Once the controller goes into an alarm state and the CD starts playing, it will start looping:

1. The CD player will be playing either a blank CD or birdsongs or whatever
2. Arduino loop:
1. fade the light up a bit
2. check the room temperature and fire the furnace if needed
1. some timer here to make sure we don’t call for heat too often
3. exit the loop if the alarm is turned off or times out
3. If the alarm is still on after X minutes (we’re not awake)
1. flash the lights
2. the CD will switch to an actual loud alarm sound or song

I put the coffee maker in there as a joke, but it’s totally possible – who knows, maybe I’ll include it!

Watch this space for updates – I’ve ordered the Arduino and a dimmer kit, with any luck I’ll have something hacked together by next week!

Pictures on Snapfish from Katie.

Pictures from Cody, including some pretty amazing shots of what appears to be Sasquatch.  Wow!

I also adjusted the timestamps on Peter’s pictures (one of his cameras wasn’t on daylight saving or something?) so they’re now in order in the album, it’s much cooler to browse through them now since they tell the story sequentially.  (Thanks to Q for pointing this out, I thought they were in order…)

In other Duoteam news, we’re still both fighting coughs.  Feeling mostly ok otherwise, but it’s proving hard to shake this thing.  Ah well, neither of us had been sick since January, and I suppose this is what we get for pushing so hard in the months leading up to the wedding.  Now if only Bruno would let us sleep in when we have time…

Tomorrow’s the Autumn Brew Review!  I remember the first year I went we still lived near downtown and I walked to Peavey Plaza by myself, drank like a fish, and stumbled home through Loring Park to our apartment.  The next year we somehow missed it (I think a coworker’s wedding was that weekend)…  And then last year Karen joined me and we took her dad and Sierra and it was the Best.  Day.  Ever.  This year we’ve got a whole posse, it’s being held outdoors at the historic Grain Belt Brewery complex, and it’s going to rule!!!

Well, finally.  I’ve managed to upload all of the pictures of the wedding taken by Peter, and I hope you’ll all agree they’re worth the wait!  He did a really amazing job, but it helps that all of you are so damn good-lookin’…  Check them out here – there’s enough of them it should keep you busy while I try to consolidate links to other people’s pictures or find a way to get them added here…

Also – you can print them online!  There’s a pulldown on the bottom-right of an image detail, and one of the options is to print on Shutterfly for decent prices.  They’re also high enough quality you can download them and print at home if you want!

The honeymoon, as they say, is over.  Although I think "they" are usually speaking metaphorically, and in this case it’s actually over – literally.  We’re home!

And it was the most fun you can have with bad weather and two colds!  As you read last week, we aborted our put-in attempt at Sawbill due to wind, rain, and cold, and headed towards Ely for two nights.  Karen got her cold in Ely, and it unfortunately peaked in congestion just as we headed out and decided to go half a mile underground to tour the Soudan Underground Mine…  The 3 minute trip down the mine shaft resulted in popped ears and renewed sneezing, but it was a really interesting tour that gave me a much better understanding of the mining history of the region.  There’s also a physics lab down there(!) where they run experiments with subatomic particles – the half mile of earth shields them from cosmic rays that would interfere with their instruments.  Pretty cool.

Karen’s cold had progressed and added a hearty cough by the time we made it to Scenic State Park for an awesome two nights of "almost camping".  We stayed in a fantastic CCC-built cabin right on Coon Lake – no running water, but they had electricity and a gas fireplace(!) so it was nice and cozy.  We spent the days sneaking out for hikes and then returning to the cabin for Karen to recoup in her little sleeping bag cocoon by the fire.  (Karen had to stop for a nap on the trail during one of the hikes).  Overall it was a really nice compromise between hotels and the boundary waters – we got to cook our camping food, but also take care of Karen’s cold, and overall it was super relaxing.  We both powered through our books, learned to play cribbage, and enjoyed the amazing scenery and hiking.

Friday night neither of us slept well – there were mice running around in the cabin, and some bird outside decided to screech every time you’d start to drift off.  Really weird, I wish I knew what it was or what its problem was…  Saturday it was my turn to wake up with the cold as we packed up to head to Duluth.

The first day in Duluth was great: a nice long walk on the boardwalk, lunch in Canal Park, shopped for some gifts, then back to the room for a quick round of cold medicine and ibuprofen.  Finally off to the Brewhouse for the finest beer they brew – their Anniversary Cherry Ale!  Karen had two of those and I sampled their cask IPA and an Irish Stout.  While I love the Brewhouse beers, I gotta say the Irish Stout at the wedding was better…  :)  Two games of Cribbage and some yummy food, and I was totally exhausted.  We watched some TV and passed out.

Sunday was absolutely gorgeous.  We got a late start, then headed up the shore a bit for an amazing lunch at Nokomis, a relatively new restaurant just 9 miles from Duluth.  Karen had a really nice wine and I got to try Bell’s Batch 8000 – this year it’s a wheat wine, like a Belgian Wit but X2, really nice even with a stuffy non-stop runny nose.

We mosied back to Duluth and took a harbor cruise on the Vista King, super nice weather and again, I got a much better understanding of the importance of Duluth as a shipping hub.  Pretty incredible examples of raw "industry" out in the harbor – huge grain towers, powdered cement storage, and an entire dock filled with enormous turbines for wind power.  Very cool, and we got to see the largest freighter on the lakes, the Paul Tregurtha. Oh, and Karen got a little trip down memory lane, since she worked for the Vista Fleet during her first smmer in Duluth as a college student. 

Then across the harbor into Wisconson for some more microbrews at the Thirsty Pagan — apparently they’ve been around since ’96 but we’d never heard of them!  Good beer, more cribbage, and we met someone who corrected a few of the rules we’d had to guess at.  But I was crashing fast so we headed to the room for a quick round of meds (and I power-napped on the floor) and back out.  We decided to do dinner at Karen’s old college haunt, Sir Benedict’s, where we had some delicious soup and sandwiches, free popcorn, and yet more cribbage.  For those keeping score at home, Karen was winning a lot early on, but I believe the final count for the week has me in the lead.

Monday morning we grabbed a quick breakfast at a local coffee shop, another of Karen’s former places of employment, then headed to the Brewhouse to fill a growler.  No fools, we decided to share a pint of their Cherry Ale – hey, it’s only served once a year!  We took a quick spin up to Hawk Ridge and saw a few Sharp Shinned Hawks and got some up close views of a Kestral they had caught and banded just before we arrived.  Coooool.

And then… it was over!  I’m writing this on Karen’s laptop as we drive south on I-35, back towards life and reality — but with a few key differences from how we left it!  It’s been nothing like we planned, but it was actually really exciting to be able to improvise and re-plan so well, and still have such fun.

More soon, and we’ll try to set up a central place for wedding photos!
