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:

* 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 !
