Just a little update, project is on a go-slow for the next couple of months whilst I deal with some none project related things. Hoping to order PCBs for new revisions sometime in August or September. Might change the DSP board for small vias on the ADAU145x and buy my self a toaster oven and fit it with a controller to do reflow on this just to make life easy.
I have been building up my speaker crossovers, well the first version using hardware I have designed:
Work in progress but the boards work. All 3 DSP boards where I hand soldered the LFCSP chip seem fine. No idea on long term reliability yet but hoping to use the above box to do some testing for this (i.e. just leaving it on a lot).
An electronics engineer and a long term electronics hobbyist. I like tinkering with stuff and making things.
