Making wine in Shenzhen: Metal hex standoff kit

in Prototypes by DP | 10 comments

cover

Often it’s not clear exactly what connector, button, switch, or part is the best choice for a project. We end up making a last minute order of 1 or 2 of any likely candidate from Mouser or Digikey. That sets the project off by about a week while we dig through datasheets and websites, make CAD footprints, and wait for the order to be delivered.

To banish this annoying time sink we’re working with Oomlout to release complete kits of parts. Each set will be nicely labeled, well organized, and have open source datasheets, renderings, and CAD footprints for Eagle and KiCAD. We call it wine making because Ian hand plucks each part from Huaqiangbei in Shenzhen. We’re posting now to get your feedback, the final kit will be available in a couple weeks.

Previously we presented the Single row cable kit, Keyed connectors kitDouble row IDC cable kit, and the Nylon hex standoff kit. Today we release our idea for the Metal hex standoff kit. Recently we upgraded all our projects to the standard PCB sizes, and designed the Sick of Beige acrylic cases for them. The cases are held together with hex standoffs and bolts. The idea behind this kit is to always have on hand the right standoff or bolt you might need for a project.

Head below to check out the contents, then please let us know what we forgot or what you find useless!

    do one actually need to include tools?

  2. Nick Johnson says:

    These kits are fabulous. I intend to buy them all.

    I concur that including tools is probably unnecessary, though.

  3. ken says:

    I found 13mm standoffs useful for RJ11 connectors…damned things are huge.

    Would be nice to have a small standoff for one-sided boards too…just need enough to clear any thru-hole pins that stick out on the other side (2mm?)

  4. asdf says:

    These part kits seem to consist mostly of stuff you can already get very cheaply off eBay. How do you intend on being competitive against the Chinese resellers, or will you be relying on your branding? (Not trolling or anything, just genuinely curious.)

    • neslekkim says:

      on ebay you typically find 50 or 100 each piece, here you can get an complete kit, and later you can complete it with the ones that you actually are going to use. Small kit for sizing etc is good.
      I’m searching around now to see if I can find a set if pic microcontrollers, but it seems like I have to buy from many instead of getting an selection of the most used ones.. (different product, but similar issue)

      • asdf says:

        Standoff kits in particular are easy to find. The only difference is that you usually get 10 of each and 40 each of nuts and screws.

  5. Nick Johnson says:

    @asdf: The individual parts, perhaps, but you’re discounting the usefulness of having a well-thought-out kit instead of having to source it all individually.

  6. Franklin Tellez says:

    When do you plan to start to sell this kit and the other ones?

  7. Cluso99 says:

    I would ditch the tools, but add
    12x Metal M3 screw (5 or 8mm)
    12x Metal M3 hex bolt (5 or 8mm)

  8. Dave Hrynkiw says:

    Heads up on importing Chinese-sourced screws. Can’t say for Europe, but North America slaps a pretty heavy import tariff on bulk screws/fasteners from China. Hope this good idea isn’t sunk by politics!
