DC connectors used by APC :Anderson Powerpole – Wikipedia

Posted by jpluimers on 2021/01/29

Different keying for each colour in the SB50 series. Note that black and grey are keyed the same making them interchangeable.

Different keying for each colour in the SB50 series. Note that black and grey are keyed the same making them interchangeable.

I bumped into [WayBack] Anderson Powerpole – Wikipedia through Cheap VS Expensive Solar Panels | 12v Touring | Project Cyan – YouTube.

APC uses some of these connectors (I have seen the yellow, blue and grey ones) in many of their systems: [Archive.is] apc battery connectors – Google Search

Images from wikipedia.

Quotes from the article:

Powerpole connectors are physically and electrically hermaphroditic, thus avoiding the need to worry about which end is the plug and which the socket, or which end has the correct polarity.

The Anderson Powerpole connector is more expensive than the older de facto standards of the two-wire trailer plug and the Molex connector, but provides a more reliable electrical connection (both mechanically and electrically), and is easier to adapt to a wider range of wire gauges.[19] Another advantage over the older trailer or Molex connectors is the Powerpole’s superior ratings to withstand 100,000 no-load insertions and 250 hot-plugs at full load. The specific hermaphroditic nature of the powerpoles is a significant advantage since batteries can be both a power source or a power sink, a power supply can be connected to a radio and/or a battery, and multiple batteries, radios, and/or redundant power sources can be connected in parallel using the same power distribution panels.

For use in amateur radio, the community has adopted a standard color code, polarity, and specific physical arrangement for assembling pairs of Powerpole connectors. One red and one black powerpole housing can be physically arranged in 4 topologically different mechanical orientations (red left, red right, red top, red bottom – when viewed from contact side with tongue up), 2 of which are mechanically incompatible (connectors won’t mate with ARES) and 1 is electrically incompatible (will mate but reverse polarity) with the ARES standard; there are also additional unusual configurations in which one housing is rotated 90 degrees. The standard is red positive and black negative. When viewed from the contact side, a mnemonic for remembering the arrangement is: “Red [on] Right — Tongue [on] Top” (note the first letter alliteration).

NDC 2019 Keynote: Welcome to the Machine – Hadi Hariri – YouTube

Posted by jpluimers on 2021/01/27

I am really glad this keynote got recorded. Still very relevant, it is as much about software development as it is about society.

Go watch it, as it gives you reason to think about your role in the software development process, and in the information fire hose at large.

Back in the days, David Intersimone was right when he created the regular blog post “Sip from the Firehose” (for early materials, see [WayBack] GetPublished – Author Information: Firehose).

The talk main thread is about current and ever growing overload of information which basically makes it disinformation, combined with the abundance of “AI” recording devices around you that basically make you the product.

Basically we reached all the tick marks of these books:

The session is not just about “how bad is the situation” (it is very), but also provides directions on how to get out of it for both people in the development process, as well as consumers, producers and sharers of information.
