# Allgemeine Situation
|
||||
|
||||
Ich möchte ein paar Gedanken bezüglich OneSecondDelivery mit dir teilen und habe alles niedergeschrieben.
|
||||
|
||||
|
||||
|
||||
Nachdem ihr entschieden habt alles nach Zürich zu verschieben hattest du mich gefragt, ob ich noch länger bei OSD dabei bleiben möchte. Ich habe dir zugesagt, wobei ich darauf vermerkt habe, dass ich mich dazumal nicht wohl gefühlt habe, da ich auseinander gerissen war zwischen Lausanne, Zürich und Luzern. Ich bin dann noch länger in Lausanne geblieben um die wichtige Deadline zu erreichen, welche aber bis heute nicht erreicht wurde. Wir haben abgemacht, dass ich mich melde wie es geht in Zürich. Jetzt nach 2 Monaten muss ich sagen das es sich nicht verbessert hat, eher verschlechtert. Ich finde es sehr schön hier in Zürich mehr mit Alena und Freunden zu machen, bin aber sehr unzufrieden mit der Arbeit und möchte das offen mit dir teilen, da mir die Kommunikation zwischen uns von Anfang an sehr viel Wert gewesen ist.
|
||||
|
||||
|
||||
|
||||
Durch Selbstreflektion merke ich, dass ich mich überhaupt nicht wohl fühle. Ich fühle mich komplett ausgelaugt - konstant. Meine Positivität ist zum grössten Teil auf der Strecke geblieben und es drückt auch im privaten Leben durch, was mich sehr stört. Am Ende fast jedes Tages denke ich das es kein guter war und nicht viel funktioniert hat wie hätte sollen. Jedes Mal wenn ich die Treppe runter gehe in Richtung "Büro" fühle ich eine Abneigung und möchte am liebsten nicht runter gehen. Das hat vor allem damit zu tun, dass ich den ganzen Tag alleine im Keller sitze und alleine an irgendwelchen Dingen herumtüftle. Es ist überhaupt kein Teamspirit vorhanden und ich habe keine Ahnung woran Inigo, Floris, oder Jerry arbeitet. Wir haben immer wieder gesagt, dass das besser wird, aber auch nach 16 Monaten ist es nicht wirklich besser. Ich bin mir bewusst, dass das zu einem blöden Zeitpunkt kommt, da sich vielleicht viele dieser Dinge ändern werden, sobald Investmentgelder organisiert sind. Aber wir sagen das schon seit Monaten und ich spüre nicht wirklichen Fortschritt. Bezüglich Team beschäftigen mich mehrere Punkte, zum Beispiel möchte ich mit anderen Leuten an einem Projekt arbeiten, um technisches Feedback zu bekommen und wichtige Punkte miteinander diskutieren zu können. Vor allem denke ich, dass wir "Experten" brauchen können, da das Development so viel schneller wäre und Leute wie Inigo und ich viel mehr und schneller lernen können was alle vorwärts bringt. Dann fände ich es wirklich wichtig auch zwischen den verschiedenen Themen Austausch zu haben mit einem wöchentlichen 10-Minuten Meeting oder so, wo alle mitmachen. Das hilft einerseits das Gesamtbild zu sehen und andererseits hilft es allen einen Schritt zurück zu gehen und sich selbst und seine Arbeit objektiver zu betrachten. Etwas anderes ist, dass ich bisher an vielen verschiedenen Dingen arbeiten musste, aber immer wieder etwas neues Priorität hatte, was dazu geführt hat, dass ich nichts wirklich abgeschlossen habe. Ich habe manchmal das gefühl für sehr vieles gleichzeitig verantwortlich zu sein, und nicht nur verantwortlich sondern auch derjenige der es ausführen muss.
|
||||
|
||||
|
||||
|
||||
Ich merke insgesamt, dass es mir nicht gut geht und sich die Situation eher verschlechtert als verbessert. Das beschäftigt mich ziemlich und ich glaube ich bin nicht bereit meine Gesundheit aufs Spiel zu setzen. Für mich gibt es verschiedene Anzeichen: es wirkt sich auf meine Motivation an der Arbeit wie auch im privaten Leben aus, ich bin durchgehend erschöpft und kann kaum aufs Wochenende warten, ich bin sehr oft schlecht gelaunt, was ich vorher nicht wirklich hatte (und das hast du ja sogar von dir aus bemerkt in Lausanne), manchmal kriege ich eine komplette Blockade beim Arbeiten und denke dass ich alles hinschmeissen sollte (was ich eigentlich nicht möchte).
|
||||
|
||||
|
||||
|
||||
Ich wollte dir vorschlagen, das zusammen zu erörtern und Lösungsansätze zu suchen. Ich bin davon überzeugt das vieles viel besser wird sobald wir alle in Zürich sind, fühle mich aber so als ob das schon seit langer Zeit herausgeschoben wird.
|
||||
|
||||
Key Points
|
||||
|
||||
- Leere versprechen
|
||||
- Bubble
|
||||
- Team
|
||||
- Ich lerne nichts mehr
|
||||
- Motivation
|
||||
- Wirkung auf privates leben
|
||||
- Signs of burnout
|
||||
|
||||
- 90% sind schlechte tage
|
||||
- Immer schlecht gelaunt
|
||||
- Konstant erschöpft
|
||||
- Ich habe keine freude mehr
|
||||
- Ich möchte niemandem mehr erzählen was ich mache bei OSD (erkläre immer alles in denselben alten sätzen)
|
||||
- Prokrastination
|
||||
- Vielleicht bin ich nicht der richtige für den job
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
**Positiv**
|
||||
|
||||
- Neuanfang in Zürich -> Mitgestaltung, Team, etc.
|
||||
|
||||
**Negativ**
|
||||
|
||||
- Nach 16 Monaten nicht so viel Start-up erfahrung
|
||||
- Ausgeleiert
|
||||
- Motivation viel kleiner geworden
|
||||
|
||||
**Kommunikation**
|
||||
|
||||
- Immer so schnell wie möglich
|
||||
- Keine Team meetings -> ich habe keine ahnung was di anderen machen.
|
||||
|
||||
Was mir sorgen macht
|
||||
|
||||
- Ich fühle mich trapped wegen aktien.
|
||||
- Möchte aber trotzdem entlöhnt werden für was ich geleistet habe

# Swashplate Analysis
|
||||
|
||||
- [ ] How bad are the vibrations?
|
||||
|
||||
- [ ] What are the steps needed to make it fly?
|
||||
|
||||
|
||||
|
||||
|
||||
1. Test without motors: Is swashplate well calibrated?
|
||||
2. Test vibrations of one motor and the other and together without propellers.
|
||||
|
||||
1. Analyze the data (vibration analysis & rpm feedback)
|
||||
2. Are the main vibration frequencies related to the rpm?
|
||||
3. What are the causes of those vibrations?
|
||||
4. Are they problematic?
|
||||
3. Are the motor shafts thick enough?
|
||||
|
||||
# Electronics Thoughts
|
||||
|
||||
- [ ] PDB is bad! No regenerative breaking possibility included. If used with regenerative breaking escs there will be huge voltage spikes which damage other things.
|
||||
|
||||
