I Believe I have a couple of 20 LED boards, Using the LM3915's, Completely assembled. I built them, Tested them, but Never went any farther. They Consisted of a Couple of other IC's as well and were also dot or bar.
Could probably give them to you for free.
Could also send you a picture of them.
If your interested, send me an email and I'll have a look for them.
and check them out.
