Pogo Pins

A Pogo Pin reference may be useful:

  • P.. and R.. refer to Pin and Receptacle (a.k.a. socket), respectively
  • Pxx  and Rxx = nominal pin diameter in 0.01 mm units: P50 = 0.48 mm

For pins, the suffix -hn indicates pin head shape, the most useful of which may be:

  • B1: 45° cone
  • J1: dome end
  • Dx: large dome, also 1D
  • Gx: cylinder
  • Ex: large 90° cone, sometimes 1E
  • T2 – large chisel

For sockets, the suffix -ntl gives:

  • n – entry shape: 1 = shaped entry, 2 = straight entry
  • t – termination: C = crimp, S = solder, W = wire
  • l – length of wire in 100 mm units: 7 = 700 mm

From what I can find on eBay, all pins have 6 mm travel with typically 75 / 100 / 180 g spring force.

Memo to Self: US-based eBay sellers charge three times more than Chinese sellers, but deliver in one-third the time.

  1. Is there a secret to avoiding the auto-play video ad that ignores the “mute button” and refuses to let you scroll away?

    1. Combining uBlock Origin with Privacy Badger works wonders for me: never browse without ’em. You can’t tell what malware accompanies those offensive ads.

      What’s amusingly referred to as my “WordAds Revenue” recently took a definite upward jump, so WordPress must have deployed even more aggressive ad placement and selection. Judging from the blank spaces on the landing page, there’s little left of my blog above the fold.

      As far as blog advertising goes, I have three choices:

      • Opt in to WP’s WordAds program to get a share of the revenue
      • Opt out, giving WP all of the ad revenue
      • Pay them to suppress all the ads

      Until the recent uptick, this whole affair has been running a slight deficit with Option 1. I suppose I could set up a Patreon account or put up a “Donate here” linky, but (from what I’ve read) neither of those options produce meaningful revenue.

      1. Your blog is relatively clean, on stock browsers I get an ad on top of the right column and another below the newest post. Both tend to be non distracting except when Banggood hogs them which leads to more BG purchases :)
        Beware however, time is not far away when your browsing history will embarrass you through AdSense :)
        Next step are dynamic billboards that trigger on your proximity and alert everyone around you to what you did last night – hopefully shopping for cheap endmills :)

        1. So last night I was browsing Amazon’s selection of router bits and endmills with their Pixel app and every product page ended with a big ad for women’s clothing. Although the models were (highly!) attractive, I’m definitely not in the target demographic and can only assume Amazon wants my eyeballs glued to the screen.

          Didn’t buy any endmills or clothing for Mary.

          1. Trick is to buy some, in my experience that’s when the real push starts :)
            Though they should optimize it not to push product you already bought if it’s not a consumable. If I pop 1k$ for an LCD TV today, chances of going for another one in the following week are pretty thin :)

            1. Amazon offered me “Subscribe and save” deals for a box of 48 AA alkaline cells, a pack of 10 router bits, and a bandsaw blade. Yes, they’re consumable items, but not on a monthly or even semiannual basis, thank you very much.

  2. Hmm, I’m reading on an Android tablet with no ad blocker installed and see no ad or video. ?

    1. Aaaand when you’re signed into your WP account, they do you the favor of not showing you any ads …

  3. I’ve had good luck with AdBlock Latitude and NoScript, all on Pale Moon. They should work on Mozilla variants; can’t say anything about other browsers.
