I know nothing about these folks except what I just read on
their web site. They offer plans to build a wideband O2
sensor display thingee. Dunno tital cost of project. This is
a commercial sevice, they charge for the complete write-up.
Think they may offer ready-made PCBs for each project too,
not sure.
