    multiconductor cables

    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...

    MIL-DTL-22759/86A

    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...

    DIN rail regulators

    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..

    PCB Contruction and Assembly Services: Who's your favourite?

    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...

    Low Battery Circuit

    "I would still recommend the PIC device - a 7 pinner." 7? , Now I'm really tryin' to figure out which one?

    Anyone know of a product like this?

    they were common hardware store items back in the day,before kitchen stoves shipped with integrated cordsets.

    Can Phototransistor distinguish between colors?

    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?

    Any serial character LCD modules?

    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

    Exterior wall sheathing?

    And yes in OBC land one would expect inspections at the footing,framing,insulation, plumbing and final by local municip, electrical inspectors are provincial

    Exterior wall sheathing?

    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?

    Video output for microcontroller

    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 http://www.dontronics-shop.com/home.php?cat=262 The obsolete motorola 6845 might have got you...

    555 timer

    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....
