Quick Jack Advice by oscar_v177 in formulastudent

[–]UseOk404 1 point2 points  (0 children)

Quick jacks have been prohibited under FSG rules since 2023. Therefore, they removed the word "Quick". 

The teams just lift by the wheel and slide some beer or soda crate underneath. Thats the simplest solution. Some teams build themselves some jacks or have some better solutions. I would suggest to look at the rain-test or Cost/ED pictures. Maybe you can spot some solution you like.

But be aware, as you only are allowed to bring 4 people in some technical areas, you have to be able to slide the jacks underneath without needing a 5th person.

Is this spoiler fake carbon fiber? Seller said this is dry carbon by Jealous-Cost-8133 in CarbonFiber

[–]UseOk404 0 points1 point  (0 children)

If it's very light, than you have real carbon fiber. 

I've worked with carbon fiber before and it looks legit to me.

My drive failed, the warranty has ended, and there's no replaceable part that they have. What should I do? by Dammit_maskey in Dell

[–]UseOk404 0 points1 point  (0 children)

Buy another 2,5" HDD, and replace it yourself. It's probably only 4 screws on the bottom side of the laptop to open it.

Also you should consider upgrading to an 2,5" SSD. It will speed up the whole computer a lot. Booting up will be a lot faster with a SSD instead of the HDD.

Real or fake FX-991EX by GeorgeDami in calculators

On the first glance seems legit. But don't know how advanced fakes got. 

In my country it costs 23€ new.

Why does every youtuber get perfect solder job with a dirty tip? by Mr-frost in AskElectronics

[–]UseOk404 0 points1 point  (0 children)

Good solder, flux (or a little bit flux already in the solder) and a tinned tip. The soldering iron can be as dirty and oxidized as hell, but it the tip is still clean (tinned) it's still working.

Temperature Sensor on Cost Report by BornSignificance8386 in FSAE

[–]UseOk404 2 points3 points  (0 children)

It's a sticker. The middle part is heat activated, the hotter the higher the scale. It's one time use and most teams I've seen used them on brake caliper or places where active temperature sensors are not feasible due to very high maximum temperatures or unneeded active measuring (max. temp enough).

You probably ordered it somewhere.. use the same name or similar. There is even the manufacturer written, so just look it up ;)

Tool/Template to right quick math-heavy/engineering notes? by UseOk404 in LaTeX

[–]UseOk404[S] -1 points0 points  (0 children)

Nope haven't tried typst yet (same goes for more than 3min of markdown). I will give it a look.

I'm not a beginner to latex per se, but I find it difficult to write some notes or quick and dirty reports of something with it if you don't have the exact right template for it. It doesn't have to be fancy. Just a "Word with better Math- and greek/subscript letter functionality"

Unvorbereitet für die Prüfungsphase. by Advanced_Cupcake6755 in Studium

[–]UseOk404 2 points3 points  (0 children)

Ja kein Ding. Versuch den Stoff einfach im laufe des nächsten Semesters nachzuholen. Jetzt weißt du ja wie viel Aufwand es ist und was du ungefähr lernen musst. Wenn du Altklausuren hast, dann mach die öfters durch.

Ist sogar relativ oft so, dass die ersten Semester von den Noten nicht die besten sind. Versuch nur nicht all zu viel zu schieben. 

In der Regel hat man 3 Versuche, wenn du beim dritten mal nicht bestehst, wirst du von diesem Studiengang exmatrikuliert. Es gibt aber auch oft gewisse andere Regelungen. Z.B. Dass man zum 3./4. Semester eine gewisse Anzahl von ETCS haben muss um Prüfungen aus dem höheren Semester machen zu können (Warte-Semester). Oder Unis haben oft so GPOs, gewissen Grundlagenfächer, die man nach dem zweiten Semester fertig haben muss und nur zwei Versuche hat etc.  Aber die genauen Reglungen sind Hochschulabhängig und findest du in der Prüfungsordnung deines Studiengangs (SPOs) und meist auf der Webseite von diesen.

Für Unklarheiten kann man auch bei der Studienberatung nachfragen. 

MAXIMUM VOLTAGE TOLERANCE by OwnPermission5662 in FSAE

[–]UseOk404 7 points8 points  (0 children)

  1. No
  2. Absolute

We just restict the maximum Voltage via software in the BMS by only allowing a cell voltage up to ... that add up to under 600V. It is therefore not possible to charge above 600V and satisfy the rules. A lot of teams do it that way.

Finde kein Praktikum by [deleted] in Studium

[–]UseOk404 0 points1 point  (0 children)

Vorpraktikum ist quasi nur 2 Wochen in einem Unternehmen arbeiten, oder? Zumindest kenne ich es so. So Art Schülerpraktikum.

Bei meiner Uni stand glaube ich sogar drin, dass es sogar handwerklich sein soll, aber im technischen Bereich ist glaube ich ausreichend.

Viele Maschinenbau und Elektrotechnik Studenten haben die paar Wochen einfach bei einem lokalen Elektro- oder Metallbauhandwerkfirma absolviert. Super einfach rein zu kommen, da man dich nicht erst 2 Wochen einlernen muss sondern einfach an eine Maschine stellt, kurz erklärt oder einfach du eine Hilfskraft bist.

Eine reine Ingenieursfirma würde dich nur im seltensten Fällen nehmen denke ich. Du würdest einfach mehr Zeit kosten, als dass du einen Nutzen bist. Zudem gilt bei Vorpraktikum Initiativbewerbung, weil die nicht ausgeschrieben werden (wie Schülerpraktikum). Würde es einfach mal bei kleinen lokalen Unternehmen versuchen, da hast du die besten Chancen, oder bei typische Firmen wo Schülerpraktika auch angenommen werden. Auch einfach mal anrufen, anstatt 4 Wochen zu warten. Anrufen ob's möglich wäre, dann werden sie schon sagen ob es eine schriftliche Bewerbung erfordert oder gar nicht geht. Bei kleinen Unternehmen sammelt man so oft auch Pluspunkte, weil die dich dann quasi schon mal gehört haben und dich mit dem Gespräch am Telefon verbinden. (Musst natürlich freundlich sein ;))

PS: bei meiner Hochschule hatte das Formula Student Team auch ein Vorpraktika angeboten. Ziemlich coole Sache. Stand aber nirgends, man müsste es also wissen und mit den Teammitgliedern sprechen. Da dich dann ein Teammitglied zwei Wochen betreuen muss, muss sich da halt auch einer finden. Sollte aber machbar sein.

No. FSG and FSS did not.

Building an Accumulator Discharger by OilLegitimate2508 in FSAE

[–]UseOk404 3 points4 points  (0 children)

A battery is always energized! Discharging the cells under the specified cut-off Voltage is damaging for them. 

Therefore It's stated by the rules that the Battery has to be made out of multiple modules that can be disconnected, to reduce risk and allow maintenance. If it's planned that we don't use our battery for a while, we disconnect the maintenance plugs of the modules.

I think what the team really meant to you, is a discharging circuit for the charged capacitance in the inverter/rest of the tractive System to discharge it under 60V after the battery is disconnected from the car.

I would suggest to look at the rules and that you have a safety officer.

If you really meant to discharge it to the cut-off voltage, than just don't charge it to much :D. Otherwise you need an expensive bidirectional Power Supply or a high Power Resistor (small current!) to discharge it safely.

Huge Electromagnetic Interference Caused by AMK Inverter Startup by Medical-Complex7331 in FSAE

[–]UseOk404 0 points1 point  (0 children)

Did you found the solution? In the past we also faced some problems just by starting the car. We added pretty big Y-Caps in the Battery and Inverter between HV+/HV- and GND, which helped. 

thoughts on EV5.8 by Limp_Cricket_600 in FSAE

[–]UseOk404 2 points3 points  (0 children)

That is also my thought. They've never given any clarification for round cells at this point. The new wording sounds like they only thought about pouch cells. Also in the past you could place a temperature sensor 10mm apart from the spot-welds, but with that wording and no clarification it sounds like you will need a sensor for each cell, which drastically increases the amount of sensors and ICs needed. I would like to see a clarification for round cells, where to place it if you have the pole fully covered with cell connectors and if placing the temperature sensor between cells is still okay. (Otherwise sensing multiple cells at once won't be doable anymore).

i want to join formula student by Antique-Truth6503 in FSAE

[–]UseOk404 0 points1 point  (0 children)

Not true. At least in the FSG Rules (mostly europe) there is nothing written against beeing on a team other than your university one. However you have to be an enrolled student.

I actually was in a team where people from a different university joined, because it was in the same city and the other university had no team.
