Two things: I'm not clear on why the first one would cost $10k. The enclosure, maybe? If he were going to sell these, the rule of thumb I heard was to charge

If he were going to sell these, the rule of thumb I heard was to charge the cost of parts x 10. (Edit: maybe a factor of 2? I forget.)
- geoah 5y agoI was wondering the same thing. PCBs are pretty cheap at this size, and the components wouldn't be THAT much more expensive to grab in smaller quantities. If someone would get a group buy started just for the components and 3d case files I'd hapilly sign up and 3d print the thing.
- ghostly_s 5y agoI assume it's tooling costs for the custom enclosure + rubber membrane but I too was confused why that was never clarified.
- tyingq 5y agoWould be nice if he broke out the $10k. My guess is mostly the cost of an injection mold for the enclosure.
- wanderingjew 5y agoMold for the silicon keyboard - the first five keyboards is going to be about $6k. After that, each keyboard is about a dollar a piece. Same with the plastic enclosure.
- pronoiac 5y agoGoing by their comment history, I think this is the article's author. You might want to make a top-level comment, like "This is the author, ask me anything".
- ghostly_s 5y agoMaybe they don't want people to ask them anything.
- wanderingjew 5y agowell, not here...
- numpad0 5y agoEnclosure at small scale can be 3D printed. Use FDM for mechanical fitment checks, then make in SLA resin printers for first couple clear case prototypes. I wish I could do keyboard as easy...
- ghostly_s 5y agoSure, if you want an enclosure that looks and feels like shit.
- bluesquared 5y agoIt's going to be tooling for the enclosure, and if there is other NRE to be considered for PCB testing (ICT, solder stencil, etc). With a $15 BoM cost, using a domestic contract manufacturer, this would probably come out to be no cheaper than $30/unit with very decent volumes, and that doesn't factor in your profit. Need to remember to pay someone to assemble it and test it.
