A brief rehashing of things I learned from making electronic devices for a living (or so I tell myself). More stuff you already know after the jump.
Looks nice, eh? I made it with my bare hands.
El jueves con los compañeros de Crear estuvimos en la CISL con nuestra charla. Es de no creer que gente del público en tiempo real twiteaba y subía la charla a youtube entre otras cosas.

En unas horitas me voy a la Conferencia Internacional de Software Libre a presentar con los Compañeros de Crear el prototipo de nuestro último proyecto, "Guitarra Vas a Llorar".
La idea central es agregar un dispositvo electrónico a una guitarra estándar capaz de mostrar acordes, escalas y canciones sobre el diapasón. Mediante LEDs (diodos emisores de luz) se indicará en donde el guitarrista debe apoyar sus dedos. El funcionamiento se completa con dos alternativas de uso:

For the last seven days I had this disease. I could not remember being this sick since I was a kid and catched chickenpox.
The first three days were like hell. Fever, alternating states of extreme coldness and warmth, generalized pain and swelling and worst of all, toothache. If I had at hand a forceps I'd disposed of half of my tooth just to make it go away. (yes, I do have a set of dentistry tools in the shack but the weather wasn't encouraging me to leave my home. No, sadly I don't have the x-ray head nor the chair. I could certainly make a good use of a dentist chair, they are really comfy.). I even had to sleep with socks and long sleeved shirts (normally, in winters like this, I sleep with no additional clothes and a quarter window opened).
The idea of spending several days doing nothing wasn't very appealing so I thought "If I'm going to be quiet doing nothing I'd better read so it's not lost time.". Well, moving was hard and trying to focus my sight on some books made me feel really odd so I strapped a wireless mouse to my chest, put a lot of blankets and the laptop on top to hold everything together. From time to time I passed out but I managed to read quite a lot, still can't make heads or tails out of some topics but it's better than nothing.
On the second day of this I gave up and it was a good move. The toothache made eating everything but liquids barely impossible and I felt weak, let alone in mood for studying.
The following days I slept in average 16 hours a day, somedays in a continuous chunk, others 8~9 and several naps. It was weird but ignoring the pain and dizziness I'd get sinusitis again just for the side-effects regarding the sleep and the dreams I had.
First. I don't know how, but I woke up like a robot for medication before the clock rung, turned off the alarm and fell asleep again just like that. And the most important, dreams. Lots of dreams, strange, livid and I remembered almost each and every one, I just wished I had taken notes because now some are fading.
I dreamt a lot with tubes, vacuum tubes. Several times I dreamt that I was in what looked like a small town, humble, electronics store of the late 40's shopping for a console radio. They were amazingly real, I could touch them, feel the veneer. I think I tried every Zenith from that era. Also I dreamt that one of my cat's nest were filled with assorted tubes, I can recall seeing a 6L6G (love that bottle shape) and a pair of 807... and 'we' cuddled by the fireplace. Yes, I'm a tubehead weirdo.
Also I had a couple of lucid dreams that I'd rather not talk about but I woke with a big big smile.
Por un lado estoy contento porque me salieron impecables los trazos, aunque el silk medio corrido. En el otro extremo estoy enojado, no puede ser que en La Plata esté dos semanas para que me traigan componentes a un precio justo. Si los compraba en mouser o digikey los tenía antes.
Esta placa me la encargaron desde el Chaco. Qué manera de bailar con el Negro Salvatierra!!. Ojalá me salieran igualitas al render.

El otro jueves me pasaron un micrófono Behringer B2 Pro para revisar, hacía ruidos como pop, frprttt , kzert... cada tanto sin un motivo aparente. Normalmente en los condenser ese tipo de ruidos son debidos a humedad o suciedad en la cápsula o algún que otro capacitor defectuoso, sobre todo con phantom power de bajo voltaje. Después de una limpieza lleva casi seis horas sin hacer nada extraño. Es un aparato hermoso y sobrio. Muy noble también.
Original en Chino ( traducido al inglés acá ).
La última vez que se me cayó la baba de semejante forma con un aparato electrónico fue cuando intenté (sin éxito) de reparar el equipo de rayos x en el cig. Releyendo mails viejos me encontré con el reloj de este señorito. Tiene todo para dejarme medio bobo por un buen rato. Es un reloj, tiene tubos nixie (no de los mas interesantes pero tubos al fin), y el diseño es exquisito pero sin descuidar la funcionalidad. Hasta me gustan los led en las bases, algo que siempre desprecié.
