Das Blinkenlights!

I made some.

Do you not know what blinkenlights are? The Wikipedia page does a remarkably good job of explaining the term. I apologize--only slightly--for the awful misappropriate of German language pieces. It really should be "die Blinkenlichten." ;)

Mine were from a kit that my lovely wife got me. Hackaday is a pretty dang cool blog with an attached store that carries it. It's a bag of electronics parts and no instructions. The board-to-board and curvy-trace design elements are both reminiscent of electronics designs from the 1950s and 60s, and it reminds me of the electronics repair work I did in the physics department at my university. The point is to reverse-engineer it and put it together--which I did:

assembled Cordwood Puzzle from Hackaday.com

Amusingly, due to the lack of instructions I attached the 6-pin 100-mil connector wrong (through-hole instead of surface-mount), leaving three of the LEDs always on and making physically connecting to it difficult. I'll eventually get a solder vacuum (not solder sucker! *shudder*) and fix it.

Then, for the ward talent show last night, I combined a Raspberry Pi 2 with my cordwood LED kit and made some blinkenlights!

I then topped it off by having the Pi play a trailer for my friend's old-computer-hardware YouTube series, hence the monitor.

The rainbow ribbon cables were lovingly borrowed from my Xilinx programmer and my SmartScope.

The Bash script on the left of the monitor is the one blinking the lights; it simply echoes commands to the /sys/class/gpio tree under Raspbian Linux.

Sapper

You know, I kind of like the library.

Sure, it's dark, and the butler insists it's haunted. Parts of it move around inexplicably from time to time, and a vestibule might be gone tomorrow and elsewhere the day after, but overall I can find what I'm looking for and I get things done.

It rather reminds me of what I imagine an old university's library should be. The smell of old books, elaborate shelving, sweeping staircases, endless shelves upon shelves, the occasional cobweb, dim light filtering in from stained-glass windows, and at night soft light wafting down from grandiose chandeliers.

Still...

Sausage Kale Soup

Hi everyone,

I highly recommend this recipe:
http://www.thecandidappetite.com/2013/01/19/spicy-sausage-potato-kale-soup/

The writer had a blast writing it. The results are tasty, even reheated at work. :)

Why am I posting this? It keeps getting dropped from my wife's Pinterest board, which is super annoying. >:-( I might have to find or write an app that keeps track of her boards that will alert her to vanished pins.

Breathe Deep

Eet eez a beeg ball of boom. Ya.

And I'd made it.

Luckily, I'm on the other side of a duralloy pressure containment door. This side has a simple, two-color design on it reminiscent of its cousins for bio, chemical, and radiation hazards, but about twice as frightening: memetic hazard.

You see, just because it's information doesn't mean it's not dangerous. Even through the double-walled duralloy chamber, it aches. Not in the head, but in the chest. It isn't too bad here, but inside, facing it? Ugh.

Pi and Typewriters

Sounds from my distant childhood, mixed as music.

Another interpretation of Pi as music. 'Cuz this has been done before (I don't particularly recommend the original, though it does involves lasers).


Yup, that's all for this post.

True Journalism

There is an article on CNet that has fantastic writing. The journalist found a modestly newsworthy topic, did his homework, and then dropped some amazing prose into our world.

I just about died laughing as I read it. The incongruity of the writer's style with the content is priceless.

Article link!

I hope you enjoy it as much as I did.

Blogger's Android app ate this post when my phone went to sleep in airplane mode. It needed revising anyways...
