Yes for the IN-17 design AVR would be my choice. I believe the AVR Tiny series are made in surface mount packages. Sandwich construction (Tube board stacked) and controller using mostly surface mount parts. This would accomplish two of my objectives.....to make a small footprint nixie clock and hone my skills with surface mount construction. I have Eagle to do the layout and I am average on the use of it. This is sounding more like a doable project. Another dream of mine is to totally encapsulate the clock in clear casting resin with only the power jack and pushbuttons accessable. there may be heat issues but a totally (almost) encapsulated clock that could be dropped without damage...I remember a light brick design that was a solid brick of resin with LED's inside...of course if any component failed... bye bye clock...what a waste of nixies....crazy idea....are there any good reference documents that cover "Charlieplexing"?...thanks again
