[TowerTalk] stack controller

[Steve Maki]

Hey guys,

After a recent lightning event I find that my 20M 3-high stack 
controller got zapped. This is an IC based homebrew design that a friend 
made for me in the 90's.

I'll be able to swap in the 10M controller as a temporary fix, but going 
forward am wondering if there is an easy commercial replacement 
available, maybe with a bit more flexibility (more relay outputs).

I currently need to be able to control 7 relays in 7 programmable 
different combinations (all involving either 1, 5, or 6 of the relays to 
be energized at a time, per the K3LR article from the 90's).

My current control boxes have 7 buttons each of which can direct access 
the 7 relay combos. I much prefer this over any rotary control switch.

Anyway, I know this is a simple task for a little Arduino box and relay 
controller - is there anything out there that is (almost) ready to go?

Thanks,
