Brilliant device: [WayBack] KP-810-19BTT Mini Bluetooth Keyboard with touchpad – Unisen Group iPazzPort

I got it via Amazon USA ([WayBack] iPazzPort Wireless Mini Handheld Keyboard with Touchpad Mouse Combo for Android TV Box and Raspberry Pi 3 and HTPC and XBMC KP-810-19S – Black: Computers & Accessories), but Amazon in Europe has it as well (this is the German link:[Archive.is] iPazzPort Mini Wireless Handheld Tastatur mit Touchpad: AmazonSmile: Computer & Zubehör; replace .de with .fr, .co.uk, to find your local link).

There are this one is 2.4 Ghz, includes a USB dongle in the battery compartment and requires 2 AAA batteries.

There are Bluetooth and back-lit versions too which cost slightly more.

Posted by jpluimers on 2020/01/03

The cool thing about elektronica-shop.nl is that they have [WayBack] Montagedraad in various colours for most diameters:

A short list:

  • 0.14 mm2: rood/bruin/blauw/groen/geel/oranje/zwart/wit/grijs
  • 0.20 mm2: zwart/bruin/rood/oranje/geel/groen/blauw/paars/grijs/wit
  • 0.75 mm2: blauw/bruin/groen-geel/grijs/oranje/wit/violet(paars)/zwart/rood/geel/groen
  • 1.00 mm2: zwart/rood
  • 1.50 mm2: zwart/rood/blauw/bruin/groen-geel
  • 2.50 mm2: zwart/rood
  • 4.00 mm2: zwart/rood
  • 6.00 mm2: zwart/rood

Translations:

  • rood = red
  • bruin = brown
  • blauw = blue
  • groen = green
  • geel = yellow
  • oranje = orange
  • zwart = black
  • wit = white
  • grijs = grey/gray
  • paars = purple
  • violet = violet
  • groen-geel = green-yellow striped

The maximum current (Amperage) depend on the area through which the current can flow. It can be roughly translated from the AWG (American Wire Gauge). See the table below.

De AWG-code wordt met name in de elektrotechniek om de dikte van elektrische geleiders en de toebehoren daarvan, zoals adereindhulzen, kabelschoenen en -klemmen, aan te duiden.

AWG  -  mm²    -  mm

4   -  21       -   5.2
6   -  13       -   4.1
8   -    8       -   3.2
10   -    6       -   2.6
12   -    4       -   2
14   -    2.5    -   1.6
16   -    1.5    -   1.3
18   -    1       -   1
20   -    0.5    -   0.8
22   -    0.3    -   0.65
24   -    0.2    -   0.5

Apple Mac OS X / OS X / macOS versions and history graphs – Wikipedia

Posted by jpluimers on 2020/01/03

Based on [WayBack] macOS – Wikipedia and follow-up of OS X – the versions and their names – as I always forget them and osx – How to find out Mac OS X version from Terminal? (via: Super User)

Release history (with release dates):

The graph with Apple Mac OS X / OS X / Mac OS versions cannot do without a graph showing the BSD and Unix inheritance.

Graph origins:

More complete Mac OS X / OS X / Mac OS and Unix timelines are below from macOS version history – Wikipedia.
