XF551 update:

XF551s

 

Well here it is nearly Christmas.  I have a modern power supply test board coming in hopefully by the end of the week.  Put together and tested ok should be a big step towards the final board.  The board itself appears to be approaching the size of the original, as I have added things.  I wonder how that happened…..:)

A big question remains.  I am considering going to a four layer board, but my current board house prices for four layer boards  is literally five times more expensive for a small batch. (50 count)  So I may have to stay with 2 layer.  It might not do much to reduce the size anyway.  I am working with non SMD parts for the most part.  It would be nice to go SMD, but I see no realistic way I can do that much SMD soldering.  My eyesight just will not allow it.  I’ve toyed with the idea of having my board house do the SMD assembly, but the additional costs could push the total cost of the board beyond that sweet spot that most Atarians will pay.  Kinda defeats the purpose.

Anyway,  I have a couple more projects in development too.  Those boards should come in this week too.  Stay tuned for more info.

Happy Holidays everyone!
