In the arduino world a program is called a sketch. The equivalent to a “Hello World” program is Blink.

Blink is a very simple program that turns on...

As part of my on going investigation on the SX70 I wanted to photograph the shutter operation: I wanted to know how log it takes for the shutter...

It is time to come to conclusions and make propositions for the year ahead. In a nutshell is has been both disappointing and fascinating. I have to admit...

I have finally found the time to implement and test in the Arduino the flash operation for the opensx70.

                  #if SHUTTER
                  shutterOPEN (); 
                  delay (51);
                  digitalWrite(FFA, HIGH);
                  delay...

I have made a PCB design decent enough to send it for manufacture. Usually the PCBs are 1.6mm, and optionally 0.8mm, but I feel I need a bit...

I am getting quite confident with EagleCAD and have “finalized” the schematic. I has been amazing learning to use the program. I have also been testing the light...

I have managed to have a working prototype of the UPCD (ugly prototype control dongle). It connects to the camera via the flash socket yet the flash is...

Success!!! I have loaded a pack of SX70 film since I feel the shutter is pretty slow. First picture only got a very small portion on the bottom...
