Today's success: Illuminating a LED the hard way. On the left is an automotive UPS controller. It will charge an auxiliary battery when the car's alternator is running, switch to that battery when the alternator isn't running, and switch the output off before the battery becomes too deeply discharged.

The connector in the upper left provides 5V, GND, and dry contacts indicating whether the UPS is on main power or backup power. My circuit uses the LED to indicate whether the dry contact is closed, allows reading open/closed status on a microcontroller pin, and allows overriding LED state (PWM control) using that same microcontroller pin.

SMS settings in Google Hangouts are now really configurable! It's now easy to force outgoing messaging to always use your Google Voice number and not end up with multiple streams. I may finally be warming to Hangouts. Well played, Google!

So I'm finally getting around to watching Undeclared (2001) on Netflix. I am haunted by an amazing memory for entertainment trivia, despite not caring for such things on the least. Undeclared really delivers with the guest appearances. I just watched the episode where Felicia Day appears for one second at the beginning and Kevin Hart verbally acknowledges doing a Chris Tucker impersonation.

Absolutely perfect summer mid-morning on the north lawn. I'm getting things done and feeling good, which is not something I can always say.

What horrible dystopia is this?
Oh wait, it's today in America.

So what do you all think: Is diabetic test strips for cash a brilliant bit of entrepreneurship, a flagrant abuse of the system, a flagrant abuse of desperate people, or some combination?

How could we address health at a societal level in a way that doesn't result in people trading their health for cash? Can we? Should we?

Believe it! The McDonald's lobster roll is among the many New England things that my friends in California couldn't wrap their open minds around. We need an exchange program.

[Posting a daily interaction summary I wrote up and posted to FB a couple weeks ago. I'm interested in how people express their individuality in corporate work environments.]

Hot today so I spent a lot of time in the (air conditioned) car and running errands in the Lilac City where I used to be a genetic superman. I'm now apparently some sort of idiot savant.

50s clean cut WM Home Depot associate.
Associate: You're still here!
Travis: I'm doing research.
Associate: On metric bolts?
Travis: Yes.
Associate: You seem very thorough.
Later...
Associate: Wow, you're still here.
Travis: I'm comparing drill bits.
Associate: See you Monday, I'm off tomorrow.

30s white BBW Home Depot cashier.
Travis: Hi, how are you today?
Cashier: I'm AMAZING, can't you tell? Just look at me.
Travis: OK, you're amazing. Can I be amazing too?
Cashier: Hmm, you have interesting hair.
Travis: (raising leg) I have urban camo socks!
Cashier: They're good for socks, but I don't like socks and never wear them. Check out my feet!
Travis: ...
Cashier: Socks are for people who bother.

20s well proportioned BF working window at Taco Bell.
Travis: Your hand is cold. It must be nice and cool in there.
Window woman: Probably just from the water and handling drinks. It's really hot.
Travis: Wow, that's too bad. This is not the day.
Window woman: (laughs) It's always the day at Taco Bell!
Travis: That's the funniest thing I've heard today.
Window woman: Really? You should get out more.

First vlog posting on my car computer project. I tend to document my projects in writing and diagrams, so this is something new for me to try to convey the concept of what I'm trying to achieve.

My first Android-x86 build running on a corebooted Asus Chromebox. No Bluetooth or HD audio support for this hardware in the kernel, so I'll need to fix that. The system image was surprisingly easy to build on my Ubuntu 14.04 server then and test from USB stick. This will hopefully become the frontend for my carputer project.

+Chad Louis​ I mention my goals a bit in the previous blog post. There's been a lot of proof of concept and mini-prototyping steps that I haven't put in my blog yet, largely because I've been trained to document for managers and not for engineers. Never mention specifics to managers until you're confident, etc. Also my workbench is a mess, making for cluttered photos. Thanks for reminding me who my audience is.

Current plan is that there be (at least) 3 new "computers". Arduino for interfacing to existing vehicle systems. Linux-based backend for storage, high level control, and access to new features. Chromecast frontend because I want Android phone mirroring.

Android Auto is close to the experience I want, but I could do without the paranoid safety controls and forced USB tethering. I'd mostly like my phone to stay in my pocket while in the vehicle. Dash cam and OBD2 integration are future features.
