Re: FIRST LED signs for purchase!
 

Resistors, especially in bulk, cost very little. My college's EE department has a rack of reels of resistors (not sure of wattage)--if a student needs one (or 12, or a few hundred for, say, 50 identical units) for a project, they go up there, take off the appropriate number, and go use them.

Figure out how much resistance you'll need, get a reel in that size, and you'll be set for "quite a few" signs.

Being nice to FIRST is absolutely a best practice—but it's important to distinguish what's a request on their part, and what's a legal requirement. Those documents linked above (including the logo standards manual) are, at least in part, wishlists.

For example, not italicizing the name "FIRST" has no implications under copyright law, and minimal ones under trademark law. It could conceivably make FIRST (and therefore Libby) angry, but what are the odds of that? (If you're bound by a particular contract with FIRST, you may be subject to additional requirements.)

More pertinently, when they say "FIRST graphics may not be incorporated into any item for commercial sale without without written approval from FIRST Marketing", despite the implication, that's not necessarily the only way to legally use FIRST's copyrighted artwork and registered marks. That's just their preferred channel for making a request for permission. (Permission from someone like a corporate officer would probably be sufficient under the law, and copyright fair use requires no permission at all.)

Despite all the legal technicalities, the easiest thing to do would still be to ask FIRST for permission: once they're satisfied, you're in the clear.

Not wanting to rain on anyone's entrepreneurial parade... But I'd prefer to buy a 27" LED monitor, $ 340 at Best Buy. Nice, bright, versatile. You can use it for presentations, signage, etc, and change the content on the fly. Admittedly it will require a PC to drive it but it isn't too hard to find a hand me down laptop that makes a good sign driver.

too bad it's not as impresive as a handmade sign :P

Re: FIRST LED signs for purchase!
 

^bump^

it doesnt seem like anyone wants to buy one....

Re: FIRST LED signs for purchase!
 

Please don't bump threads. If nobody posts here, then it should fall into the background. It means that people simply aren't interested in your product. If your interested in offering a different product, feel free to come back and post a new thread. Sorry if that sounds harsh, but I think everyone here that was interested in hearing what you had to say has already heard it. There is no need for us to take the time to re-read the offer and frankly it wastes our time. My time may not be that valuable, but many people here are rather important even if they don't act it.

Sorry for the bluntness,
Jason

lol okay...

Re: FIRST LED signs for purchase!
 

I would certainly not be angry. :) I was just making a friendly reminder, that's all.

^exactly.

Re: FIRST LED signs for purchase!
 

You're missing the point.

Alan explained very clearly that you are not following accepted engineering practice. Logic dictates that you at least attempt to understand the correct method.

In other words: You've been lucky so far, but it's still the wrong way to do it.

Resistors are inexpensive
You've been lucky
It is not because of the transformer you used. You've been lucky.
You should be worried about current flow.

In today's litigious society even a high school kid can be on the losing end of a serious lawsuit. Just imagine your sign suffers a failure, and the resulting fire kills someone. A reasonable defense may be that you followed accepted engineering practice - but not doing so will really get you in hot water, particularly because it's a commercial product for sale.

Not trying to rain on your parade. Consider this a part of your learning process. No charge.

The best way to promote your product, in my opinion, would be to ask off-season event organizers if you can demonstrate your product at their event. If they say yes, bring a sign and some business cards. This will allow you to gauge interest and establish contact with interested parties. Unfortunately, many off-season events have already happened (possibly all of them) but there is always next year, which gives you an entire year to continue product testing and development.
