Very good questions to which I don't have good answers After I have a proto that's ready for production, I'll do some research and hopefully the numbers will add up to something that's agreeable. The bill-of-materials cost is higher than the OSSC (it seems), and the qty will be lower so it will not be super cheap, but no point in having it made if the price is so high nobody is going to buy it either. A couple of hurdles is shipping outside Norway, and also even with a small run of a 100 units - the money rack up to something that can't be considered hobby activity. One scenario would be to have the boards made 70% complete, and hand-assemble the expensive IC's until the numbers add up to something that justifies a proper production batch.Any idea what price range at this point and/or availability? Great project. Keep going!
