I don’t even know if anyone reads these posts. Perhaps really I make them for myself, to chart progress, and refer back to later on. Well, actually here I am now reading this for reference, so yes mate, uts quite useful to yourself to write up these things.

So with an light dependent resistor, micro-controller and signals into MAX I’m finally on way to measure shutter speeds.

With current set-up that needs tweaking and improving we’re getting the following initial results.

Deimos controller speed setting:

  1.  shutter fully open                         640 milliseconds
  2.  shutter fully open                         340 milliseconds
  3.  shutter fully open                         240 milliseconds

 

Heres normal shutter speeds in fractions then millisecond figures we are looking for.

/th second                     milliseconds

1/1000                             1

1/500                               2

1/250                               4

1/125                                8

1/60                                 16

1/30                                 32

1/15                                   66

1/8                                     125

1/4                                     250

1/2                                      500

 

Once the shutter gets closed (it will eventually close over completely) we should see faster and faster speeds. Presently the measuring resolution isnt good enough the accurately determine these speeds.
