Also the NPN which I hope is the right spec 497-2598-ND 40V 600mA TO-18
The relay Reed DPST 500mA 12V 306-1035-ND
I forgot to get an DC input jack but I can get that from rat Shack with the perf boards
What else do I need?
The relay, transistor and sockets are all correct.
Now you just need a power supply. I like using a center tapped 12V transformer, rectifier, filter cap, a 7809 and 7905 to make +/-5V then onto a 317 and 337 to make +/-2.5v. This is seriously overkill having two regulators. But each of the regulators is like sixty cents a piece, so having all that noise filtering is cheap.
Could do it with a rectifier, filter cap and a pair of Zeners. Or could go with the modules like Bruce did. But no matter how you slice it, you gotta have +/-2.5V.
