    EDIT: SOLVED

    Thanks

    Hello all,

    I've been asked by my church to help them with a couple sign issues before easter.

    They have a 5'x10' channel letter backlit sign up at one of the campuses.

    I want to remove the channel lettering and put up a piece of acrylic that size.

    the only pieces I can find that size are white though, the sign is a light blue background with white letters.

    I only have a 24" cutter.

    My question is can I cover the whole thing in translucent blue, then cut out the white letters and put over the blue?

    Will it still light up properly?

    Thanks

    I have never installed the chip, but here is some general advice.

    1. Don't use magnetized screwdrivers when working with electronics.

    2. Ground yourself out prior to touching anything, (a grounding strap is ideal)

    3. If there is an old chip to remove use an IC extractor or if you use your fingers work VERY slowly alternating sides and pulling up, you don't want to bend the pins.

    4. When putting the new chip in, make sure the pins alight in the holes before pushing down (Also make sure the orientation is correct, pin 1 is where it is supposed to go)

    5. Sometimes you will need to GENTLY squeeze the pins inwards to make the chip fit. Take care though because the metal tabs will bend/break very easily.

    That makes it all sound very complicated but it's really not, just take your time, be careful and you will be fine.

    Joshlindt had it right.

    Calculate as follows

    Your cutter is running on 120 volts and the amps on my 721 is .5 amps or 500 milliamps.

    So...

    Formula Resistance ® = Voltage (E) / Current (I)

    In Action Volts(E) (120)/ Amps(I) .5 = Resistance® 240 ohms

    Formula Watts= Current Squared (I^2) * Resistance ®

    In Action Amps(I)(.5)^2 * Resistance® 240 ohms = Watts 60

    Woot for self taught electrical engineering!!!

    (MIT offers most of their classes for FREE online for those who want to self teach / can't afford school otherwise. I love the project and I'm getting information that others are paying 6 figures for, though I don't get the pretty piece of paper at the end of it...)

    I have a local salon wanting some extensive vinyl work done. We are looking at doing the top and bottoms of their windows listing the services they offer and the products used. they have 2 door so hours of operation on each plus the standard we accept M/C Visa etc etc and gift certificates available. Looking at doing a 3 color pallet, they use a lot of green and pink inside so matching those colors and outlining in white for everything. I

    Thanks all for the reply, I guess I didn't make it clear. This will have to be printed yes, I am not going to try and replicate this with cut vinyl, but I don't have a wide format printer either.

    What if it were printed on matte paper and use 3M spray adhesive to attach to the ceiling tiles?

    I have a client who is wanting this pattern replicated on 2'X4' pieces of vinyl to be applied to ceiling tiles.

    I will need about 60 of them. Any suggestions on what to do or is this even feasible?

    The artwork is from Morocco and hand carved and then painted.
