Community Lab (KDAB Berlin) | Sprint Sat. 21 May 11:00-19:00

[Joseph P. De Veaugh-Geiss]

Third times a charm, as they say!

After a couple of setbacks due to Corona, I am hopeful that this time it 
will work out and we will finally be able to meet in person to set up 
the community lab :)

Drum roll please ... Save the date, on *21 May from 11-19h* we are 
meeting at KDAB Berlin to set up the lab for measuring the energy 
consumption of Free Software!

If you are interested in joining, please be in touch. Everyone is 
welcome :) For those who are not in Berlin but would be interested in 
travelling to join us, contact me as we should have funding to support 
your trip to the Sprint. There are several non-Berlin-based community 
members I would love to see there!

And if there is simply no way you can come to Berlin but would 
nonetheless be interested in setting up a lab near you, let's talk. 
There are certainly ways we can support each other, and perhaps KDE Eco 
can support the setup financially!

Details are below, including Corona policy for in-person attendance.

Very much looking forward to it!

Your community manager,
Joseph

*What We Need*:

_Hardware_
  - Computer 1 (Data Aggregator): To collect data from power meter
  - Power meter (PM): BE recommend Gude Expert Power Control 1202 series 
(EUR 300-350) -> already purchased
  - Computer 2 (Reference system): BE recommend Fujitsu Esprimo P958 
computer (2019); however, for getting set up we can use any computer and 
later invest when needed
  - We can also set up measurement tools with an inexpensive Gosund 
SP111 power plug (or similar plug compatible with Tasmota firmware) [1] 
and PINPOINT compatible tools [2,3] (briefly discussed at community 
meetup on 13 April):
