Our device is carried in aircraft. We typically use 27500 TE or TG cables and the designs are blessed. :)
That series of cables seem to top out at 6 to 8 conductors. Is there another "aerospace" spec that includes
higher conductor counts? 24Ga with 12/24/48 conductors? shielded preferred. My...
I somehow ended up as a liaison ( for lack of better words) between engineering groups working on approval of a device carried in aircraft.
The folks that I would expected to know do not seem to know/have flammability specs on MIL-DTL-22759/86A conductors, spec'd by someone long gone.
Where...
I gotta wonder what device wouldn't operate safely with a
regulated 0.5v overvoltage.
Sounds like a device that has a 5volt regulator of its own inside..
Interesting to hear others rates
The guy we are happy with would probably charge about $65 per board up to 10 or so. figure a buck a part.
seems like 'yall think thats 'spensive.
course I can get him to crank em out over a weekend if necessary.
All by hand , but consistant, faults are usually...
suspect one could calibrate focused optics shining onto
three sensors each with coloured filter lenses to sense the resultant colour. The relative intesities should tell you something about the active colour?
Keith has it pegged
even guys like www.elabinc.com seem to want a pretty penny
for their (guessing) pre burnt micros
Roll your own or find some of the open source code available.
D
And yes in OBC land one would expect inspections
at the footing,framing,insulation, plumbing and final by local municip, electrical inspectors are provincial
If I read you guys correctly you are critical of the OBC for not recognizing 'glass as a sheer control material.
Does your code accept drywall as such?
IMHO
A single chip solution is unlikely. There is a reason video cards cost and are as complex as they are.
Unless you learn vhdl/verilog and program an fpga etc.
I think this is about the simplest

There are some micro based projects that control
a computer CDROM to play audio tracks (not mp3)
elector magazine did one- you could select the track to play
Since you understand the 555:
take a second 555 with an interval that is two pulses long,
use the second 555 to disable the first 555
or logic gates....
