Want to hire PIC programmer for quick job

  1. I need a VERY simple PIC project done but I am not an engineer. I do
    know it is a simple project because I have read accounts of how it is
    done, I just can't translate that into actually DOING it for myself.
    I know it uses the PIC model 12C508A.
    So, my first question is, how should I go about hiring someone for
    this job? I think it would require less than a day's work for an
    engineer.
    I do not want to pay more than I have to.
    Second, what should I expect to pay for such a job?
    Finally, anyone here interested in it?

    Hi, Howard. You might get better results if you offer something in the way of
    a description of what you want done. You also might get opinions on whether
    you require an engineer at all, or just a tech or a hobbyist who's got a bit of
    a homebrew ICE and a programmer. If it's that simple, you might not need an
    engineer. But if you've got an electronics project that requires real thought
    instead of just "turning the crank", where you want to hire someone who will
    commit to thinking it through, getting the whole job done, and guaranteeing
    that your solution will work, you should employ an engineer.

    Typically, engineers I've worked with and for will charge $75.00 to $250.00 per
    hour and up for side jobs or contract work, depending on their qualifications
    and level of expertise. If you really need one, that's a bargain.

    Good luck
    Chris

    I can do that, and since one of my hats is "Tech Writer," I can even sit
    down and write a spec with you. But without more information, it'd be stupid
    to offer a quote. "I can name that tune in 4 notes..."

    Cheers!

  5. The project involves modifying an off-the-shelf 24 hr. quartz analog
    clock movement by means of inserting a PIC which will speed up the
    movement by, for example, 0.03% (so you end up with, instead of a 24
    hour rotation of the hour hand, a 23 hr 56 min rotation). I know of
    at least one instance where someone did this, and even have a
    detailed, if difficult to follow (for someone not familiar with PIC
    programming) step by step guide as to how he did it (using a PIC
    12C508A).
    Since I will be using the fruits of this labor for a commercial
    product, I feel it is only proper that I reimburse someone for their
    help.
    An ideal candidate would reside in the New England area, although the
    project could succeed via correspondence, as well.

    If anyone is interested, please send private inquiries to


    Thanks for the feedback from those who have already given it.

    And, by the way, I'm not averse to learning digital electronics and
    PIC programming, I just have my hands tied with the other elements of
    product design and marketing and I'd like to get this to market as
    soon as possible. (I do have a couple Myke Predko books waiting for
    me, someday...)

    If it's just a fixed offset then you should be able to change the
    crystal, there's only one or two in use AFAIK, 4.194304 MHz and
    32.768KHz. If you are intending to modify many of them, this may work
    out cheaper (only two pins to solder) than having to program PIC chips,
    solder them in, test them etc..

    I am not interested in bidding on your product,
    but I would like to get the other project details.
     
  9. Wouldn't it be easier to solder a variable capacitor in parallel with
    the clock's quarz in order to tweak it a little (in fact, there may be a
    cap already, and it just needs adjusting).

    To get the hands to move as much in 23 hours and 56 minutes (86,160
    seconds) as they would in 24 hours (86,400 seconds) means that the
    32768Hz crystal driving the clock would have to be speeded up by
    0.02786% (240 extra seconds every 86,160 seconds) to about 33,680.9696
    Hz. Putting a capacitor across the crystal would only slow it down,
    and I'm pretty sure that even completely removing any existing cap
    would more likely cause it to stop oscillating than to get anywhere
    near 33681Hz.

    Will the OP please chime in and tell us what the purpose of the product is?
