Hi all; heres something i was thinking of rigging up:
Ingredients
$7 dollar kitchen timer from evilBay with LED display
Some wire, solder, soldering iron
other assorted electronic parts...
(cooking analogy ends here)
anyway, i was thinking - somehow wiring the DPDT? brew switch to activate the LED stopwatch - ie. when you press the switch to brew coffee, the timer starts, hence displaying shot time, and stopping when you press the switch to stop the shot.
...Im going to be really incoherent here because Im still trying to figure it out in my mind. Im thinking there are some possible problems that my limited electrical knowhow has no solutions for:
- not enough poles on the switch - easily solved with a 4PDT switch or something. i hope.
- the switch mechanism on the brew switch is a simple open/closed thing...activating a stopwatch requires an open/closed/open instantaneous button press kinda connection (well...thats how i see it in my head). how do you convert the simple on/off action into a button press kind of action?
- the timer will have to be powered and reset manually. oh well...no big deal.
Anyway...hoping you knowledgable coffeesnobs (Mal? Sparky? Anyone???) will be able to tell me if this project is:
a) feasible
b) a good idea in the first place
c) none of the above
sorry...i just love tinkering. i really should have done engineering.

) a la Les Paul or Stratocaster. Come to think of it...itd be interesting to see what it looked like if you changed all the switches to that style, then switched out the steam knob for a tone/volume knob looking thing & changed the steam tip to the end of a 1/4" jack...
