“Luggable” power pack

June 9th, 2009

Paul and I are leaving on a cross-country train trip next week, for Jen and Shawn’s wedding in Colorado. I’m sure the view will be great, and I’m bringing a handful of books- but Paul and I are geeks and we need our electro-doodads. If only we had a way to run our Nintendo DS and PSP for the ~30 hours that the trip will take…

I sifted through my stockpile of junk, and came up with this:

IMG_0643

It’s kind of like a mega-size Minty Boost, or a heftier version of the Kensington power pack. The Minty Boost weighs in at about 6 Watt-hours, depending on the AA cells you use. The Kensington pack is rated at 7 Watt-hours, with a Lithium Ion battery. This brick occupies the middle-ground between the Minty Boost and a car jump-start battery, weighing in at 84 Watt-hours. It should run and charge a Nintendo DS for at least 30 hours.

It’s built almost entirely from junk that I had lying around the house: (Your house may vary.)

  • 12 Volt 7 AH Lead-calcium battery
  • Aluminum box, in my stockpile of project enclosures
  • Receptacle end from a cigarette lighter extension cable
  • DC-DC converter from an old Nokia phone charger (for a phone I no longer use). Swapped a resistor with a trimmer pot for 5V output.
  • USB sockets from a dead 4-port hub
  • Heavy duty wires and quick-disconnect plugs from a dead UPS
  • Odds and ends: Switch, mounting hardware, fuse holder, wire nuts, foam weather-stripping, JB-Weld epoxy, heat shrink tubing, LED, resistors

Parts I had to buy at the local Fry’s:

  • 10 Amp fuse (Pack of five for a few dollars)
  • 12V 1 Amp lead-acid battery charger ($20)
  • Cigarette lighter plug for the charger ($2)

Now here’s hoping that nobody thinks it’s a “hoax device”…

P.S. I’m still working on the Robot Odyssey DS port and in fact there are some interesting bits of UI working now- but I haven’t quite reached another blog-worthy milestone yet.

CIA

Some more crazy ideas for CIA‘s future…

  • “Sparklines.” A pretty novel (but not new) way to present data history inline with text. I’m already building up some graphing infrastructure for CIA around my ‘fidtool’ library. Just imagine how cool it would be to, at a glance, see the activity history for all the projects on the screen.
  • Wiki integration. The whole “documentation” section of the site is really just a read-only wiki at this point. It generates those pages from reStructuredText documents stored with CIA’s source code. If the documentation browser were promoted to a full wiki, users could maintain their own client scripts, installation instructions, and such without having to bother me ;)

But actually, those are the most tame ideas that have been circulating. Some even more outlandish ones:

  • Why not build the entire CIA site on top of an existing wiki engine? It would be great to have a wiki-like way for anyone to edit project/author metadata, but with some form of version control to allow rollback in the case of abuse. Really, I could take nearly any wiki engine out there and give it a special namespace for stats targets.
  • I’ve been searching for a new way to organize the real meat of CIA’s site: the stats browser. Each stats target (one project/author/host/vcs/etc.) can have several types of content attached to it. It can have user-assigned metadata, automatically generated ‘related’ links, the recent commits, and a list of children. The big problem with this is that the larger pages (project, author, gnome) just have too much content to display all at once. For any target, large or small, I really want to see the most recent information first. This suggests somehow merging everything into a single chronological list. I’m not entirely sure how this will work yet, but I’d like to focus on the commit list but attach information about related/child items as appropriate. An important part of this would also be allowing the user to choose where to display additional information. This will probably mean “More…” links at the bottom of the page, plus some way of interactively expanding the inline information attached to each commit.

Music

Amanda found a really spiffy web service: pandora.com. It’s a streaming music server with an intriguing non-genre-based method of categorizing music. You put in a handful of artists or songs you like, and it tries to stream similar music for you. It actually seems to be working pretty well so far.

Turkey Day

Thanksgiving this year was great- I spent most of my time back in Colorado with my family, whom I’ve spent far too little time with recently. I baked an apple pie with my brother’s help, ate far too many of my grandmother’s homemade rolls, and really just got some much needed time to catch up. Much of the Boulder crowd was busy with other things, but I was thankful for the time I was able to spend with David and Jen.

I’m not sure when I’ll be coming back next. I’m trying to conserve both my money and my vacation time at this point. I’d like to do something for New Years’ Eve, but any plans for that are still in their early stages.

And so another weekend

October 28th, 2005

Well, here I am waiting at my gate in SFO. I was about to write about how well LJ works on my phone with the bluetooth Stowaway keyboard, when the web browser died and nuked my entry-in-progress. So, bah. Maybe a blog poster app would be another good task for Python.

Anyway, this weekend is still largely unplanned, as usual. Much pumpkiney goodness shall ensue tonight, and tomorrow shall bring starcraft and at least some form of fooding. Aside from that, everything will be a surprise.

Busy week so far. I’ll have to write more, especially about the concert, when I’m not so worried about my browser kerploding.

Bluetooth

Over the past week or so I’ve had Bluetooth on my mind a lot. Why? It’s a silly protocol- low bandwidth, disgustingly complicated, still a bit on the expensive side.

Well, for starters, I’ve been messing with it a bit at work. One of the bugs I was tracking down in VMware’s virtual USB controller was triggered by a Bluetooth dongle. This required some reading of specifications, writing of debug tools, and playing with Bluetooth devices. (Incidentally, never buy SMC Bluetooth dongles. They’re crap. I have protocol analyzer dumps to prove it.) I got to mess around with BlueZ just a bit to test a Bluetooth mouse and keyboard on a Linux guest OS. It was actually much easier than expected, and I look forward to using their API. Kudos to the BlueZ folks.

Furthermore, tomorrow I should get my shiny new Nokia 6620 in the mail. I have all sorts of crazy ideas racing around my mind that somehow involve Bluetooth, the Python port for Symbian, an NSLU2, and GPS. Crazy ideas aside, I’ll at least be using a Bluetooth Stowaway keyboard, and possibly using it to network my Python apps with a laptop machine running Linux.

Modern cell phones really amaze me.. they’re what PDAs really should have been all along. Phones get smarter and “smarter”, but at their very core they will always be devices for communicating. Nowadays that might be email, mobile blogging, and multimedia messaging, in addition to old fashioned voice calls- but they are still communication devices. What’s a PDA? It communicates with nothing. Fundamentally, a PDA does nothing that a pad of paper couldn’t. Pads of paper never need new batteries, or OS upgrades.

On a similar note, my old Motorola V188 seems to be trying to make peace with me, as it knows its useful lifetime is now limited. It’s actually been working really well for the last week or so. No half-dropped calls, it’s actually been ringing.. crazy.

Travel

I already have another trip back to Boulder planned for the weekend before Halloween. It’s just a short weekend trip, leaving Friday afternoon and returning Sunday night. I wanted to try a trip that didn’t require any vacation days, since sadly they’re now more valuable to me than anything else VMware has to offer. I don’t have any plans for this trip yet, but anything is fine by me as long as I’m around my awesome friends. I’d kinda like to have a bit of a pie cook-off with David. I have yet to experience his pie-fu first hand, and it’d be great to know how to make at least a simple pie when I’m home for Thanksgiving.

Ah, Thanksgiving… I’ve just committed to being home for that. I’ll want to spend as much time as practical with my family, since my grandmother will be back in town for the first time in years. I’ll have to see what my friends are doing, I might still be able to spend the weekend with them. I need to go back to looking for plane tickets for Thanksgiving, but the prices depress me. It’s worth it to have full use of the two full days I get off from work, but blehh… I hate sinking so much money into air travel. It’s all going to go into Jen’s paycheck eventually ;)

Food

Sigh, not a lot to report food-wise. VMware’s cafeteria does nothing to curb my addiction to cereal and bagels. The most interesting thing I’ve cooked at home recently has been some random stir-fried beef and veggies.

Exploring

I’m back in a bit of an adventurous mood, slowly working toward some kind of balance between my life in Boulder and my life here. For the last few days I’ve been interested in urban exploration, though I still have this itch to find somewhere really dark. I’m certainly no astronomer, but I love staring at the sky. Near my apartment you can count all the stars on your fingers.

Thursday I biked to work. I need to investigate new routes. I wasn’t the only one biking on El Camino Real, but it still seemed just a tad bit suicidal. It takes me about 45 minutes, but I’m out of shape. I need to convince myself to do this on a more regular basis. Besides being fun, biking has always been liberating to me. I hate parking. A lot. Actually, I hate parking more than pretty much anything else. I’m sure there are plenty of things worse than parking, but I’m having trouble thinking of them at the moment. On a bike or on foot, you can go anywhere, stop anywhere, without all the time, money, and frustration caused by trying to find a place to ditch your vehicle. Thursday night on the way home I could effortlessly take a detour through downtown Palo Alto to grab a Gyro, then cut through Stanford just for the hell of it.

Friday night I decided to visit San Jose. I’d never been there before, or even really looked at a map. I was in the mood to get lost. I was driving in straight from work, so my first job was to find some parking. Blah, See above. After far too much driving around and squinting at rates, I somehow ended up in a big $18/day garage near the hockey stadium. I later found some cheaper ones, around $6.. but the damage was done. I figured I’d never need to drive into SJ again, Caltrain is so much more convenient. Well, I got lucky that night. I ended up leaving at around 2 AM. Nobody was manning the gate, and it was open. I crumpled up my ticket and laughed at the fall of the weak parking garage regime.

Overall, it was a great first impression of downtown SJ. It didn’t seem small, but it was in a way compact. You never had to walk very far to hit a restaurant, park, drinking establishment, or something culturally significant. It was different from most of San Francisco, where you end up walking through big pockets of emptiness. The crowds in town Friday made for good people-watching. The clubs were packed, so it was easy to spy on the throngs of twentysomethings waiting in line outside to dance the funky chicken and peace out to the latest hip-hop in their fishnets, or what have you. I found a great little burrito place that was still open and receiving a lot of business at 11:00.

By far the coolest thing I ran into Friday was an art car show outside the San Jose Museum of Art. Picture a darkened plaza, a circle of palm trees and a circle of the strangest vehicles you’ve ever seen. I suck and I didn’t have my camera with me. There was one covered with reptilian scales, a giant guitar, a Radio Flyer wagon.. it was a sea of LEDs and EL wire, with a few strobe lights for good measure. There was one painted entirely gray, covered in random plastic parts. Half a brick phone here, part of a Star Destroyer there, a Ghost Busters proton pack on the hood. Close up, it was a mosaic of plastic toys from the 80s. From farther away, it could have made a pretty convincing space ship. Or maybe a time machine. Heck, if it was a DeLorean I might have mistaken it for some kind of new-age TARDIS. Then, my eye caught the Phenomenauts stickers. It turns out the art museum was having some kind of halloween costume party and concert, which explained a lot of the interesting crowd that night. Sure enough, later that night I walked by a window in the museum only to see the Phenomenauts playing on stage. Yep, that was random.

Saturday I left the car at home and spent some time exploring Palo Alto, then headed back to San Jose to see Wallace and Gromit. What a great movie. Anyone that hasn’t seen it needs to, especially if you’re a fan of the short films. I had time for a little more wandering in SJ before and after the movie. I had my camera with me this time, but the cars were gone. The downtown crowd on Saturday wasn’t nearly as interesting. In fact, the city was a bit on the empty side- I got there during an SJ Sharks game. Pretty much everybody seemed to either be headed to the stadium (the big foam sharks on people’s heads were a subtle hint) or headed to a latin music festival of some sort in the convention center. Admittedly, I didn’t stay in SJ too late. I was a little tired, and the last northbound train leaves at 10:30. If I did want to stay later, I’d have to spend the night there, or maybe walk back. It’s only 12 miles or so between downtown SJ and Sunnyvale. Bicycles seem appropriate in this situation.

I think next on my list of things to hunt down is a nice dark sky. Looks like a lot of bay area astronomers camp out in Lassen Volcanic National Park.

Tell me,

October 4th, 2005

did Venus blow your mind? Was it everything you wanted to find, and did you miss me while you were looking for yourself out there?

DIA, PDX, SFO, BART, Caltrain, Sunnyvale… stop. Late last night I got back from my trip home to Boulder. It was a long travel day, and I’ve had a lot of odd things stuck on my mind. This weekend was amazing, a chance to temporarily replace the depressed loneliness and isolation with the feeling of warmth that comes from knowing you have friends and family that really care about you.

I went far too long without seeing Jen- she was still in Seattle when I left for California. Jen and Kendra have both been on my mind a lot lately, and it was teriffic spending most of the weekend around them. It was also great being back around David and Evan. This weekend made me realize just how much I missed them, in a way that I never saw when we were roommates. Christy took this weekend as another excuse to fly back to Boulder, so I got to spend some time with another friend that has a special place in my heart. I even got to see some unexpected folks- Mike, Leah, Jessie… Yes, there are people I’m leaving out. I love you too, I’m just starting to ramble ;)

Friday was really the only day we planned out at all. Sushi Tora, then Serenity. It was most excellent. The sushi, sashimi, and sake really hit the spot, and I got to meet so many friends I haven’t seen in months. Then Serenity… an awesome movie that we have all been looking forward to for quite a while. It makes me sad (you know why if you’ve seen it and you love Wash) but it was a great end for the series. Saturday afternoon was Starcraft with Christy, Evan, Dan, James, and Andrew.. at Space Grant. It was a bit eerie being back in the engineering center, but we had a great time. Saturday night was the fantastic pizza cook-off that David already described quite well in his blog. I spent Sunday afternoon with my family, met David and Evan for pool that night, then finished up the weekend with a late night viewing of The Princess Bride with Kendra and David. I got a little more time to hang out with Kendra and Jen on Monday before heading off to DIA.

Yep, an awesome weekend. And now I’m all alone back in Sunnyvale, the ass-end of Silicon Valley. I will have to do this again quite soon, for my sanity if for nothing else.

Kerpow!

June 15th, 2005

I’m glad my Dad reminded me on the phone this morning- I almost forgot to plan a visit to Mt. Saint Helens on the way to Seattle. First though, I think some lunch is in order. Time to head to downtown portland to look at the edibles a bit.

Does it creep anyone else out that they don’t have self-service gas stations in Oregon?

Something for everyone

June 15th, 2005

Colorado has all the evergreens you could want, and the amazingly
spiffy aspen tree. Still, every time I travel I find myself fascinated
by the local trees. Northern california, of course, has the giant
redwoods.

The
Avenue of the Giants along highway 101 is something I wholeheartedly
recommend, but I think what impressed me most about the trees in
California was their quantity. I’m really starting to fall in love with
the whole area. Despite the low altitude, northern California has some
spiffy mountains. Of course, there’s the ocean. Monday evening I
visited Muir Beach- it was too cold to enjoy really, but there was an
amazing scenic overlook:

I’ve
also found myself really falling in love with San Francisco. It’s been
friendly for such a big city, and drinking cappucino from a little cafe
in North Beach really brought back some good memories of Rome. I’m
looking forward to having all this just a quick drive away. Anyway,
last night I wound up in Portland after following 101 north then 299
east, then hopping on I-5. Now I just have to decide what if anything
to do here, then head toward Seattle to meet up with Jen. I’ll send
more pictures later. It takes way too long to upload these on a GPRS
connection.

A few pictures

June 10th, 2005

Before the trip, I wired my car with GPS, power, and a GPRS internet connection. It seemed incredibly geeky at first, but it’s acually proven really handy in a couple insances. Best of all, the power adaptors and USB hub all tuck nicely in the area to the left of the passenger seat. Last time I was on a road trip with my family, we had a giant plywood box full of archaic electronics in the back.

Dad helps unload the car in scenic Salt Lake City.

Mmm, salt flats.

I apparently drove through a pretty big butterfly migration. Sadly, I witnessed the last second of life experienced by about a dozen butterflies. Countless more gnat fatalities were recorded, but they’re far less cuddly.

This brought back lots of memories from the SmallSat competition. Luckily, Reno had far less snow this time.

My brother and I as we enter California, with just a little cannibalism on the brain after all this driving.

Yay, it’s my future home. After looking at many of the apartments we found online, it was easy to settle on Fair Oaks West in Sunnyvale. I put in an application today and they reserved the apartment- I should actually sign a lease in the next couple weeks.

Just a little something for Sean’s collection.

We spent the rest of the day driving around San Francisco, seeing plenty of bridges and rush hour traffic. It was disappointing that the traffic was confined mostly to onramps, and the really scenic areas went by quickly.
