Taradov's sniffer is great - if you can get the parts, and can afford to wait for the PCB to ship, have a surface-mount oven, and so on - but alas he isn't selling them.
So I opted for a Cynthion instead, which also isn't shipping (yet) but promises to be available Real Soon Now™:

.. similar device, a bit more feature-laden .. and supposed to ship at the end of the month. Grr...

- mschuster91 3y ago> but alas he isn't selling them. Selling electronics is hard. You need a ton of upfront cash to order all the components, have to deal with a boatload of legal compliance stuff (if you're in Europe: RF interference, RoHS, registering and paying money for eventual recycling, CE certification tests, translated instruction manuals that have to accompany the product even though they are completely pointless), shipping, customs, refunds, repairs, your device bricking someone else's device, trademarks/licensing and associated fees (HDMI I'm looking at you), refunding people when your project fails for whatever reason but you already had to spend money (particularly the RF interference stuff has sunk many a project)... In contrast, just putting out a board design and BoM is waaaaay easier. No way for anyone to hold you liable for anything.
- gregsadetsky 3y agoJust curious, what about "PCBA" services i.e. those places that make the PCBs but also mount / solder components for you? Is it generally possible to give them a BOM and ask to populate a whole board (i.e. order and receive a completed board, without having to solder everything)? Or are there necessarily going to be parts -- like the Cypress or Lattice chips here -- that the PCBA vendor will probably not have access to? I'm just imagining a middle point between "here's a BOM" and "here's a finished product you can order" (with all of the regulatory issues that you're describing). Could there be a "click here to have it created & soldered for you, but for this to still be a DIY thing" i.e. one click order-a-finished-board?

- wrs 3y agoTo order assembled boards from JLCPCB you just have to upload the PCB design files and BOM/placement files and give them a credit card. People are even recommending ordering the Cypress part from LCSC (JLCPCB’s parts division) already. So they might be able to completely assemble this with a straightforward enough order process. However, the minimum assembly order is two boards. Edit: Another potential issue is that their in-stock parts do vary, so you wouldn’t be guaranteed of a successful order from an old BOM. The designer would probably need to update the files periodically.
- iancmceachern 3y agoGetting the boards physically manufactured is just the tip of the iceberg. There is typically FCC testing that costs tens of thousands, emc/emissions testing, and then dafety testing (UL, etc.) If it's required. It can cost hundreds of thousands to do all those things just to legally be allowed to sell your product in any real quantity.
- rescbr 3y agoAs I understand it, development kits (such as this board) are exempt of certification. Nonetheless, the rest of your argument still stands.
