This is a specialized clone, but readily available on ebay and here www.epalsite.com/store/meduino-mega2560-r3-pro-mini-board...
Another attempt at Focus Stacking - this time 26 exposures at f/2.8, each with a DoF of ~0.1 inches. Still have some gaps, but getting better
(compare with: www.flickr.com/photos/lharkness/5567173320/ which has no stacking but is at f/.7)
Completed repair. Just need to add new capacitors C37-40 but these aren't part of the main CPU circuit.
Point light ( Mobile phone led with rolled sheet of paper)
Exposure: 3
Aperture: f/4.5
Focal Length:52 mm
Focal Length: 53.4 mm

When I got my Macbook Pro a few weeks ago I knew I wanted to upgrade the memory as soon as possible. So in anticipation of the memory arriving I had an old Hard drive laying around and photographed the control circuitry on the back.
Su nombre vienen del inglés Read Only Memory que significa Memoria de Solo Lectura ya que la información que contiene puede ser leída pero no modificada. En ella se encuentra toda la información que el sistema necesita para poder funcionar correctamente ya que los fabricantes guardan allí las instrucciones de arranque y el funcionamiento coordinado de la computadora. no son volátiles, pero se pueden deteriorar a causa de campos magnéticos demasiados potentes. Al encender nuestra computadora automáticamente comienza a funcionar la memoria ROM. por supuesto, aunque se apague, esta memoria no se borra. El BIOS de una PC (Basic Input Operative System) es una memoria ROM, pero con la facultad de configurarse según las características particulares de cada máquina. esta configuración se guarda en la zona de memoria RAM que posee este BIOS y se mantiene sin borrar cuando se apaga la PC gracias a una pila que hay en la placa principal. Cuando la pila se agota se borra la configuración provocando, en algunos equipos, que la máquina no arranque.
