Hi mister_e & all who have contributed. I am quite new to PBP and this is my first post to this list. I just found this demo a week ago, read the thread, ordered the parts, assembled a proto board on Saturday and - (insert Windows USB Device da-dink! sound) it worked FLAWLESSLY, the first time. I am either lucky standing on the shoulders of giants - but oh, my, what a good feeling.

I have been tinkering incessantly since then.
Thank you for giving me super powers.
