== Start the live ==

=== Avant la conférence ===

* Brancher HDMI laptop
* Démarrer le beamer
* Configurer le laptop (1920x1080 en miroir)
* Démarrer OBS sur le PC
* Recadrer et redimensionner la source "Template Capture" dans la scene "STREAM SLIDES" si besoin
* Pareil pour la source "Template Webcam"
* Changer le tire de la conférence dans la scene "Template Title"
* Changer le titre de la conférence dans les "Information de la diffusion" à droite
* Vérifier qu'il y a de l'espace libre sur le disque dur
* Allumer le micro cravate et tester le gain, la voix doit arriver dans le orange en parlant normalement
* Le son de manière générale devrait toujours etre entre -6 et -12 dB

=== Démarrer la conférence ===

* Démarrer une video avec musique d'attente (lien youtube "waiting music" sur le navigateur chrome)
* Démarrer l'enregistrement et le stream en étant sur la scène d'attente (le micro est desactivé à ce moment la)
* Switcher sur la scene de conférence lorsque le conférencier-e est pret-e
* Arreter la musique de fond
* Qqun vérifie au début de la conférence avec un laptop/smartphone et un casque que le son est OK
** pas depuis le PC qui stream, tout le son qui est sur le PC passe dans le stream !

=== Pendant la conférence ===
* Suivre les questions/commentaires sur le chat Twitch
* Vérifier que le gain du micro est toujours dans le orange, ajuster si besoin
* Si probleme de micro, il est possible d'activer le micro de la webcam, qui sera degeu mais c'est mieux que rien
* Faire répeter les questions (peu audible grace à la reduction de bruit)

=== Après la conférence ===

* Passer sur la scène "The End" (le micro est alors coupé)
* Remettre éventuellement une musique d'attente
* Laisser le live tourner (2-3mn) sur l'écran de fin (ca évite que les gens qui ont du lag/buffering voient le live couper avant la fin)
* Arreter le live et le recording
* Uploader la video sur Youtube avec le compte de fixme.hackerspace

= Power consumption review (oct. 2023) =
Début septembre on observait ceci (en gros, quand le local était vide):
L1: 22W
L2: 140W
L3: 690W
total : 752W

Maintenant mi-octobre
L1: 0W
L2: 50W (mais devrait pourvoir descendre à 0, après discussion avec le FABLAB)
L3: 425W

Total: 475W

=> différence 275W (et probablement qu'on pourra monté à 325)

Remarque: sur la 1ère mesure, on ne voyait pas vraiment les pics de la conso du frigo (ce qui était bizarre), donc sur la seconde mesure la conso de cette appareil n'as pas était pris en compte (pour le moment en tout cas, je vais essayer d'extrapoler une conso moyenne)

Le but maintenant est de mettre tout ce qui fait du sens d'être allumé lorsque personne n'est au local sur L3 (serveur, frigo, ...). Si bien que L1 et L2 devrait être à zéro si le local est vide.

== Power saving ==
Pour donner une idée, voici différentes consommations d'éléments qui ont été éteint (mesures pas tjs très précises):
*- foo + composants non utilisés dans l'armoire serveur (injecteur poe, switch) : 90W
*- baie de disque : 125W (+ 20W juste pour l'alim en mode éteint)
*- imprimante en veille : 35W
*- gros power usb : 10W
*- multiprise prusa : 15W
*- plusieurs mini switch : entre 10 et 15W
*- alimentation machine dessin : 8W

== Next! ==
Jusque là l'idée était de supprimer ce qui consomme si personne n'est dans le local (et qui ne font pas de sens). L'étape suivante sera de réfléchir des appareils (que l'on soit présent ou non) peuvent moins consommer: exemple les switchs Dell sont à 96W (voir plus haut). Pourront-on n'en utilisé qu'un seul? Ou en mettre un nouveau qui consomme beaucoup moins?

'''note : si on ajoute 50W d'économie supplémentaire au 325W, cela voudrait dire qu'on a divisé par DEUX la conso d'électricité en mode inoccupé!!!'''

Les pistes qu'il faut explorer (pour y réfléchir et en débattre):
* le switch (voir ci-dessus)
* le frigo : à première vue, la conso annuelle doit tourner au tour des 272KWh / an (soit 112CHF). Mais un frigo de class A qui consomme 66KWh/an coute 1400,-. Autrement dit difficile d'envisager un achat. Par contre, pas dit qu'on en trouve pas un qui serait jeter et qui consomme moins...
* l'éclairage: on dit couramment qu'une ampoule de 5 W led est équivalente à 50W en filament. Donc un ratio de 10. Les strips led du local c'est 280W (allumé en valeur par défaut) soit un équivalent de 2800W en vielle éclairage.... (note les conso des alim seul avec leds éteintes c'est 60W).
