No I haven't seen this but thank you for bringing it to my attention. I think that assembly should be fairly straightforward if one can solder. That really isn't difficult for those who haven't done it. I see that the whole kit including circuit boards, enclosure and components comes to $108.00. Not a bad price in my estimation.

Jorge O. would be the one to address whether this could be accomplished more reasonably since he is an electronics engineer.

Thanks again.
