Repair together! 

Someone brings you a broken device, what do you do? 

PRE-DIAGNOSTIC
1. Listen to the owner; check for: 

• suspcious smell
• physical obvious shock
• water damage - SHAMEFUL

BUT Vacuum cleaners -> 80% of the time it's the plug because people often snatch it out of the socket instead of gently pulling it out. 
When you struggle, please check ***tube because there's always someone who fixed the same device before you
Ifixit is good, but ***tube is nicer 

OPENING TOOLS; what you need: 
- screwdriver + flexible screwdriver
- Tweezers
- prying tools

Some screws should be crime -  for some you have to manufacter your own screwdriver.
Sometimes there's no screws at all, which is worse - some cofeemachines are just glued together --> damage becomes inevitable

Interesting to check the right to repair movement: https://repair.eu/


check for mechanical failure - After you dealt with screws: 
    

• is it spinning/moving? should it be doing that?

• • As people replace metal gears with plastic ones its becoming harder to fix/check

• Look for debris
• ...
• Tools
  • Lubricant grease
  • glue
  • citric acid (beware of WD40) -> it's useful to get something moving, but is quite aggressive to plastic or rubber
  • Optical lens cleaner - CD players that do not detect the CD, usually its just a small lens that is dirty
    • https://www.intogadgets.nl/contactspray-waarvoor-gebruik-je-het-niet/
    • Most of the time you would use isopropyl alchohol for battery damage
  • Do not descale your coffee machine with vinegar. Use citric acid instead

check for electrical failure 
Fuse: electrical component designed for safety. if too much current, then it opens the loop as prevention.
Check the fuse and if current passes through.
Check the switch

MULTIMETER CONVO:

•     ;;;;;;; FILL IN ;;;;;;
• How to use a multimeter :::::: https://repairtogether.be/guidance-tool/
• Prove that u can stroke through the cable?? to check continuity without breaking anything

ELECTRONICS COMPONENTS

• FUSES

• • The hardest part is to find them.
  • Sometimes the word "fuse" is written, sometimes just F
  • Sometimes a blown out fuse is not the cause
  • When you replace a fuse its IMPORTANT to use one with the same rating

• CAPACITORS
•  Types: https://www.powerelectronicstalks.com/2020/04/types-of-capacitor.html
• Mac capacitors: if you see the inflated dome, it's already failing. 
• Electrolytic chemicals or something?: https://www.britannica.com/science/electrolysis
• Basicsssssss:

• • MULTIMETER
  • COMPONENT TESTER (for SMD comps you have tweazers)
  • SOLDERING IRON

CAREFUL 
Microwaves can be dangerous
The size can matter - huge washing machines = preferably say no
Senseo machines are very popular so there's a specific workshop on that :-D --- https://repairtogether.be/video-reparation-dune-senseo/

THROWING OUT - NO WAY! / JETER - PAS QUESTION !
