Again, I have to apologize that this is being dragged out in public...it's not by my choice.
If there is a genuine warranty issue that caused 8 of your units to fail, return them to me and they will be repaired at no cost. Yours were just some of many that we ship day after day (all of which are fully tested,) and we have had no other reports of problems like the one you describe. But if the buttons were used correctly, we will be happy to take care of it for you.
Also, If you are getting more blow through of light than you like, consider adding the diffuser inserts. If lights on the ceiling bother you, you'll want something like this for that style of button no matter what you use for illuminaton.
I won't be discussing this further. RandyT's responces to me in email is not helpfull, but be-little me. So I give up. I am ripping these from my machine. I will just settle on the unlighted buttons I originally had. I guess I am just too stupid to dp this, right?
My responses were not meant to belittle, merely to explain why what you were condemning as errors or lack of clarity in the documentation is actually not a problem with the documentation, rather a lack of necessary, rudimentary electronics knowledge on your part. I don't know of a nicer way to say something like that without making someone feel like they don't understand things which they don't understand
While I do know that the sentence "The USB port can deliver a maximum of 500ma" will have no meaning to someone who doesn't understand what "ma" or the concept of current is, there's only so much that can be reasonably covered in documentation for a device.
I can't stress enough that folks take the time to understand the very basics of electronics before delving into a project like this. It doesn't matter which approach you take, or the parts you use. The concepts are important and will be necessary for a properly functioning and safely implemented panel. We make our parts with the proper resistor values and specify the voltage to be used. That's about the most we can do. Just as a manufacturer of Christmas tree lights can't keep its purchasers from hooking 30 strands into a single home AC outlet, we can't prevent someone from trying to run 30 NovaGems from just the USB port if they are hell-bent on doing so.
If you choose to deal with GGG, I can help you understand these things, but you have to be patient, provide the information I ask for and don't proceed until you get the answers to your questions. If I was standing next to you, I could stop you when you are about to make a mistake and prevent it. From here, I can only ask questions, provide help based on the answers I get and hope the user can understand the things I write. Some days it's not fun, but fortunately those days don't come around very often.
