TL;DR: Raspberry Pi models 1..3 become hotter and hotter under load; no housing gives best cooling.

How to change the control of a Somfy RTS roller blind from 2 to 1 remote – Projectionscreen.net

Posted by jpluimers on 2020/01/20

This procedure works for Somfy RTS motors to:

  • removing an additional channel
  • removing an additional remote

The trick is to have one remote/channel that you want to keep working as you need that one to initiate the deletion process:

  1. On the channel/remote you want to delete
    • Test with the up/down button that it is indeed the one you want to delete
  2. On the channel/remote you want to keep
    1. Test with up/down button
      • The Somfy RTS motor show now work
    2. Press the  small button with a pen
      • The Somfy RTS motor now should “wiggle”
  3. On the channel/remote you want to delete
    1. Press the  small button with a pen
      • The Somfy RTS motor now should “wiggle” again
    2. Test with up/down button
      • The somfy RTS motor should now do nothing
  4. On the channel/remote you want to keep
    1. Test with up/down button
      • The Somfy RTS motor show still work

XW6600 WOL – stopped working on Windows 10 – my trusty APC PDU to the rescue

Posted by jpluimers on 2020/01/17

A long time ago I wrote in Mac/PC: sending Wake-on-LAN (WOL) packets « The Wiert Corner – irregular stream of stuff “I’ve succesfully woken up these machines: HP XW6600 running ESXi 5.1 ThinkPad W701U running Windows 7”.

The XW6600 have now been demoted to Windows 10 machines that I only need every now and then, so most of the time they are shutdown.

However, with the installation of Windows 10 however, they stopped reacting to WOL (Wake on LAN).

Per web-search results, I’ve tried all the permutations of the below settings to no avail.

Luckily, my trusty APC PDU AP7921 (and little sister AP7920) helped out: when setting the “Reboot Duration” to 30 seconds or more (so the power fully drains), it can be rebooted.

Note that since I bought these a long time ago, they have been replaced by these:

Firmwares:

Power usage:

  • an XW66000 with 32 gigabytes of RAM and one hard disk takes between 0.6-1.2 Ampère of current, which at 230 Volt is 140-275 Watt.
  • over one day that is between 3.4 and 6.6 kWh

Settings tried

How Douglas Engelbart Invented the Future | Innovation | Smithsonian

Posted by jpluimers on 2020/01/15

Two decades before the personal computer, a shy engineer unveiled the tools that would drive the tech revolution

Don’t read this as a historic piece, but as the potential we are still going to experience what was not just sketched by a true visionary in 1968, but also demonstrated back then: [Archive.isHow Douglas Engelbart Invented the Future | Innovation | Smithsonian.

I am including one of the pictures below by Christie Hemm Klok that shows how far Engelbart was ahead of his time: not his initial invention of an input device (the mouse) “chord” kind.

After that, read about his 1968 presentation: The Mother of All Demos – Wikipedia

Finally, watch the video below, well worth watching the more than one and a half hours.
