Thanks for those  words.

Yes we have to lock forvard and allso look backwards to.
To day I had a digital video signal that had to be terminated corectly. And 0403 was litle to bigg you will se in this
picture. http://ebs.homedns.org/bilder/komponents/komp34/index.html

And my reserch in history handcraft is giving me feling that we are just a bit longer ahead in time.
Shown att thes pictures betwen hardwire and circuitboard.

Tubes Nuvistors and Transitors. 

And this board whith just holes in metall whith transistor soldered thru.
