  1. I learned afterwards that some of the group thought I had just met the special lady there in Vegas, leading Erik to honor me with a new nickname of "Rush Hour" - lol - but I feel I should make a clarification, lest some of those in attendance think I am truly bonkers. Amy is from Toronto and she came to Las Vegas with me. I was leaning towards not attending, but talking with her Tuesday afternoon and deciding "Sure, let's go to Vegas together!" had me booking flights that evening. It was her first time there and we're both outside-the-box sort of people, so we decided to really do Vegas - which of course means a quickie wedding, right?
  2. No idea if I'll be attending this year... recently moved to a new condo and currently moving our shop to a larger facility - all while working on some decent projects that are very involved time-wise. I just can't predict accurately enough if time will actually allow me to leave long enough to attend. It will be a last minute decision, so if I make another appearance (which would be 4th in a row?), it will be an unconfirmed surprise appearance.
  3. Sign Industry Power Grab?

    What if your wife is into that sort of thing?
  4. How or why would I read your blog, when it isn't linked to through your profile at all? Even if your blog is all technical, this particular piece is not. It's scaremongering and nothing more. I know you're new here, but I manufacture LEDs. I know full well the challenges involved with getting clients educated about good product vs bad, domestic vs offshore, short cut vs reliable. I still would never stoop to write that kind of crap and pass it off as an educational piece, since the very same thing could be done for every single technology out there. You can find enough example of bad installs, failed products, fires, etc... from every single type of electric sign and IMO it's just completely wrong to lump them into a single piece and pass it off as an accurate representation of what is out there. There is no denying there is bad product out there - I'd be the first in line to say that about other LEDs products (my track record on here speaks to that). But this piece of writing is a pile of horse shit. It's the kind of thing some backroom political operative using hyperbole and exaggerationg (or even fabrication) would put ou there trying to smear his opponent (pick a side, they all do it).
  5. Yeah, for whatever faults other posters have had in their product promotion, they never stooped to this level. I can only imagine the outcry if say, Manuel wrote a fictional piece about poorly made neon, code violations, fires, bankrupted business...
  6. I'm not an EMC guy - don't much like them, to be honest - but that piece was complete trash. You had the decency to post "speculative fiction" in the thread title, so I guess instead of "buyer beware" it's "reader beware" with this one? Whoever wrote it and thought it would be worth sharing should be ashamed.
  7. It looks that way because it was cut and pasted from elsewhere and the tags were included.
  8. If it's known in advance and dimming is part of the first time install, it's not really a problem for either neon or LED - it's when it has to go in after the fact and the system simply doesnt have the wiring, space or compatible components to make it happen. That's why I think *if* this sort of regulation ever gets implemented, it's on new installs only.
  9. I'm an east coast guy through and through, but this sounds like it's coming from someone who's never been there. Despite the negatives, the "Left Coast" has a whole lot of positives and it sure doesn't seem like Erik or any of the other Californians are pulling up roots and heading east. The pros still greatly outweigh the cons.
  10. A little OT, but always worth repeating to help people learn about LED modules... You've probably tried adjusting the voltage usine the Axiom PSUs and noticed how other modules change in brightness. That is technically one way to dim resistor based LED modules, but the drop off happens quickly in the top range and under 8V the module probably doesn't light up at all. If you adjust voltage like this, any current regulated modules won't change in brightness until that bottom 'shelf' and then just drop off very quickly as well. This is done so that regardless of voltage drop through a chain of modules, they'll all be the exact same brightness as long as they are above a certain minimum. People don't realize it, but they could be feeding 12.5V to the beginning of a string of modules and getting only 10V at the end (or less). So not only would resistor based modules be different in their brightness, they will also degrade differently. The proper way to dim them is to use that PWM signal I mentioned earler (or other techniques) that still feed the LED its full voltage, but allow smooth dimming from 0-100%, like RGB systems or EMCs would have to in orders to mix colors properly. There are times when we use resistors only, or even nothing but LEDs at all, but the prodct will be used in one specific way only and not give the sign company or end user any ability to misuse the product. Any variables like distance, number of LEDs or modules, voltage drop, etc... would be eliminated first and only then would we build/supply non current regulated products.
  11. Almost all constant-current LED modules are fully dimmable, as are regular resistor based modules. The thing is that you don't dim LEDs by just reducing the voltage, since they require a minimum voltage just to turn on. What is typically used is either a dimmable LED power supply, or a separate device that goes between the power supply and the LEDs... it still supplies the full voltage to the LEDS but applies a PWM (pulse width modulation) signal across the wires that - in layman's terms - makes them appear dimmer while still receiving their full voltage. It might require a re-design for some companies to make their modules forward-compatible with an industry standard dimmer device, but it's not a big thing. The problem becomes when you have multiple power supplies in the same set of letters that need to dim equally, and you need to network or tie all the PSUs to one master dimmer. It will require extra wiring between PSUs that could prove more complicated than some shops will want (or be able) to deal with - especially if the power supplies are internal to each letter. It would be too logistically difficult to force companies to retrofit these sorts of signs, to it would probably only apply to new installations... IF it ends up happening at all.
  12. Something big this way comes?

    Meh. How good can the sign be if only one guy stops to read it over a 0:49 span?
  13. Why do I feel like a LinkedIn social media campaign has found its way onto the board?
  14. Looking for a job

    Are you a permanent Chicago guy at this point Gary? I'll keep my eyes and ears open for you.
