28x TS3704 quad voltage comparator
14x MJE340 NPN transistor
14x 1N4148 signal diode

24x 8-pin DIP socket
28x 14-pin DIP socket

14x IN-13 Nixie bargraph tube

3x Prototype PCB, 1-hole island, Eurocard size

1x 12V AC/DC adapter

All of the passive components were bought from Digikey, while the ICs and transistors were bought from Mouser, because they were considerably cheaper. Allspectrum.com sold me the prototype PCBs, the AC/DC adapter, and the high voltage power supply designed for nixie tubes. Sergey Bochkov at tubes-store.com sold me the actual nixie tubes. Even though Tubes-Store is run out of Chelyabinsk, an odd industrial city in Central Russia, and it appears that I was only the 5th person to ever buy from the site, they are cheap and shipping was reasonable.

I am very interested in building a project like this, the parts list says 170 (One Hundred and seventy) 10k resistors are used, is that a typo or are there really that many 10k resistors used? If i were to build a one channel visualizer, would i take this parts list and divide it by half (other than the parts where only 1 is used of course)?
