Re: New EZ Keyer Kit

A simple errata sheet should take care of it.  You might also mention that the washers on the push buttons should go on the underside of the top cover with the nuts on top.  Having the washers on the underside of the cover works great to keep the spacing right so no strain is put on the 3 jacks once things are tightened down.  
I've done some tech writing in my day and wrote a whole bunch of lesson plans when I taught electronics in the Army back in the 60's, 70's and early 80's so I know how you can have a whole bunch of proof readers check things, but until someone actually uses the instructions to build the device, you won't catch all the errors and maybe not even then, LOL.
Seriously, those were the only errors I could find and I absolutely love the way the case looks made out of the PC board.  That is one fine idea and not difficult to put together at all as long as you pay attention to the directions.
I never do unless I run into trouble, and I just use my miter saw's table as a jig and press the bottom and a long side tight to the 90 degree wall & base.  It's easy to tack solder the two pieces, swap sides and do the second side the same way.  Once the two sides are on the base, the end pieces get done the same way and it all winds up square, no tape needed.  The tape/rubber band method is probably the best for those who don't have the tools I do though.  No matter how you do it, get it square and it really looks professional.
