In the top-right corner is my old soldering iron that I used to build circuits with. The scale makes it look ridiculous next to this modern circuit board that was floated in a solder bath (irons are so last-millennium!).

Detalle de un enorme montón de teclados de ordenador que esperan ser desmantelados. Éstos probablemente son residuos de Europa, EE.UU o Japón exportados a China, porque es más barato mandar estos residuos peligrosos a China que eliminarlos correctamente en el país de origen.
La cantidad de productos electrónicos desechados a escala mundial ha sufrido recientemente un crecimiento brutal, con 20-50 millones de toneladas generados cada año. ¡Si es difícil de imaginarse lo que significa esta cantidad de residuos, pensad en ello como esto - si la cantidad estimada de e-waste generada cada año se pusiera en contenedores sobre un tren llegaría para dar una vuelta entera al planeta!
La basura electrónica representa actualmente el 5% de los residuos sólidos urbanos de todo el mundo, casi la misma cantidad que todos los envases de plástico, pero mucho más peligrosa. No sólo los países desarrollados generan este tipo de residuos; Asia desecha cerca de 12 millones de toneladas cada año.
De los residuos solidos urbanos, la fracción de los residuos electrónicos es, sin duda, la que crece con mayor rapidez. Ésto se debe en gran medida a que en los últimos se está cambiando con mayor frecuencia de teléfono móvil, ordenador, impresora, equipamiento de sonido, etc. Sin embargo, los mayores causantes de este problema son los teléfonos móviles y los ordenadores, pues son los que se cambian más a menudo. En Europa los residuos electrónicos están sufriendo un crecimiento del 3 al 5% al año, casi tres veces más rápido que el total de los residuos. Además, se espera que los países en vías de desarrollo tripliquen su generación de residuos electrónicos en los próximos cinco años.

The brains of the operation! I love the mechanical aspect of camera building, but adding electronics to the mess is also a thrill. Here I have my previously-featured SLS shutter controller, which is an Adafruit Trinked microcontroller (running on the Arduino IDE), hooked up to a lithium-polymer batter for power, mini solenoid for shutter actuation, and some bits and bobs for user interface. The little white square near the left of the camera is a 10-position rotary DIP switch, which is used to control the shutter speeds. Unlike the potentiometer I was using before, it has obvious detents to show where each speed lies - it feels really nice. I used a binary weighted digital-to-analog circuit to interface with a single pin on the Trinket - really simple stuff, but I'm proud as a mechanical engineer for figuring out that little bit of EE nonsense!

Lux is my proof-of-concept platform for my new electronic shutter (see SLS, single leaf shutter). A secondary goal for this camera was to make it completely homegrown, meaning no parts from existing camera manufacturers, with single-element lenses from Anchor Optics.

Also you to them , Been an inpatient in York Hospital for over a week now , Having Flickr keeps me at least a bit more active thank you to everyone
my new Canon gear. back after a couple of years. Sony was great and offered a lot of benefits but I wanted a full frame set up and the Sony was just out of my price range, last shots with my Sony a77 before it was boxed up and ready for Ebay

SET 3 – West Point Wal-Mart
Speaking of the Electronics department, indeed we find it right next door, occupying the center portion of the back wall. And yes, like I said, the large, open feel of the Photo Center results in a rather small, cramped feel for Electronics, at least comparative to how the department is set up in most Walmart stores, that is! It was pretty difficult to get good angles of this, so for this view I had to settle for a pic out in the actionway, with that annoying price sign getting in the way. You should still be able to get the overall gist, though, and I also like how we can see a fair deal of the black shelving in the aisles as well as the video game shelving on the far left.

These places are public so these photos are too, but just as I tell where they came from, I'd appreciate if you'd say who :)
Photographed using the Hanimex 110 IF, and Lomography's "Orca" 110 format film.
Taken in my bedroom.

The main board from an Ensoniq Fizmo synth.
The voltage regulator (far left edge of board and nestled between the two sides of the heatsink and labelled LM2940T) is one of the types that goes bad and sends too much power to the rest of the board. It's rated for 1A but when it goes out it draw more than that.
I'm replacing it with a brand new MC7805CT which is a LDO (low-dropout option) 5V rated for 1.5A, and going to use a new external power adapter (wall wart) which is 1.3A.

1973 Even today, one of the best tuner. The complex structure of the Pioneer electronics is fantastic. Difficult to get a TX-9100 today.

Noch heute einer der besten Tuner. Der aufwendige Aufbau feinster Baulemente ist fantastisch. Es bleibt schwierig einen Pioneer TX-9100 heute zu bekommen.
This is the "Pentax ME Super"; it is a 35mm SLR that was produced by Pentax from the late 1970s to the early 1980s. Overall it is a farily standard SLR from that period.
This camera originally belonged to my father. I have only used it a couple of times, and I noticed that the pictures looked quite dull and grainy. I think that there might be something wrong with either the shutter mechanism, or in the electronics of the camera itself.

Taken for the Macro Mondays theme "nothing bigger than a penny."
See the adjacent photo in my stream for a photo that has a penny in it for scale.
Back to school to me is all about labelling, so every year my trusty Dymo labeller comes out of the cupboard. As you can see, it doesn't get used much at other times.
Treated Myself to a lil gift today. have a feeling that 50mm wont be coming off my camera much. Now just to find some partially photogenic subjects.
Seen Here: The PCB out of the bag! (Torch see-through vision!)
So, today my PCB for the LED matrix arrived from BatchPCB! For what I paid, the PCB arrived fairly quickly - I ordered it on the 15/02 I believe, and it arrived 11/03 -- 26 days, which is pretty good (they state 19 business days).
The quality is very, very impressive - far better than anything I could pull off at home. The silkscreen and soldermask makes it look really nice, too.
Soldering it was a joy, although there was a LOT to solder and it's all surface mounted.
I had a few problems at first; it wasn't lighting the matrix at all properly but I soon realised with my new design (transistors on the cathodes) I have to write the transistors HIGH to get a LOW on the cathode, so a quick line of code changed to get that working.
Then for some reason the top half of every letter was flipped. It turns out this was my fault: I messed up when making the package for the LED matrix in Eagle, swapping the matrix's 5th cathode for my system's 8th, 6th for 7th, 7th for 6th and 8th for 5th. This was fairly easy to fix in code, however.
Finally USB isn't working to program or communicate, but I can configure the FT232RL chip (after all, it's sending the clock pulse that's driving my ATmega168). I think I have an idea of what's causing this, but I'm not sure yet.
