I’ll see what I can do. I was thinking about the timing issue last night and it seems to me that if there is some latency in whatever relay I use then it *should* at least be consistent. So if the timing is ‘wrong’ at least it will be wrong in a way that just requires a fudge factor.
I won’t be able to send them back – I got a pretty good price on them – 2 for $25.00 plus $9 shipping. I’ll look for the electronic and see if that can be purchased separately.
