Cool I got featured on the original Hex Bright project page by Christian (the creator of the HexBright)

I updated the original HexBright fix post with an update to use an 8MHz crystal vs a 16MHz one. From my experience in fixing these, both 8MHz and 16MHz seem to work with no observable difference. (although I am not exactly sure why both would work in theory).

So far I have fixed about 6 HexBrights from folks that saw my site since I made the original Blog post in 2017. Only one had damage from reverse polarity, the rest all had dead crystals. The crystal appears to be the most common failure point.
