OK, so i was off by a factor of 10? Probably my head being affected by the rain! Now, we can go back to our regularly scheduled program and look at two traces at the one frequency?
You did enough for today. Graham, apparently did too. Me, I'm just getting frustrated learning the nuances trying to create a very complex label.
I never do anything easy. I'm making a label which is non-square where the outline template was in DXF. I then added the drilling guide for 11 holes of 1 size and 1 hole of another. I added some lettering and some symbols. I still don't understand layered drawings in the package I'm using. This label is probably 3" x 6".
So, I give it to a sign place and they made two labels for me. 1 laminated at $30 and one non-laminated at $20. They messed up. My PDF's could be enlarged without incident, but when they printed it, it was in a lower resolution than required and the writing looked blurred. I still learned that I can't use a drill and then ream the holes, but a pilot point bit seems to work. Tested on 1 hole. I gave the job back to them and give them 3 choices: 1) Do over; 2) Refund $ or 3) Refund $ and find out what they did wrong. They chose "do over".
I had printer issues and stack overflows when printing so i had to sort that out.
The plan was learning which I did. Now I have to find a better way. So I have to figure out how to put 3 labels on a piece of polyester. Find some white laser printable self-stick polyester. Find some clear as a "cold laminate". I asked Staples if they could laminate "one-side" and that was misunderstood because the operator never heard of laminating one side before.
I found some nice sterile, disposable, sharp biopsy punches that makes really nice holes in my polyester, so that's a plus. I tried two clear sheets and I like one better than the other.
I do like the expensive label's color of white, but not enough to be worth the cost. $30 for 1 vs about $2.00 for 3 if I make them.
I still don't know the "best way" yet. Punching will give me the cleanest edge on the label. A pilot-point bit can drill the label and the plastic case at the same time, but the edge won't be as clean. Laminated Paper doesn't drill well at all. It tears. I don't have a drill press.
Earlier, I did investigate having labels laser cut external and internal and printed. Not likely. Membrane keyboards are yuk. Conductive elastomer won't cut it at low volumes. All in all, a very slow learning process.
I can envision printing a paper label and applying releasable adhesive with a stick and apply to case. Mark the hole centers. Remove the template and throw away and clean the case. Punch the label. Apply label with self-stick back adhesive.
So, I learned something.
