+ | * One thing I reckon you shouldn' | ||
+ | |||
+ | |||
+ | ==HOW TO SOLDER== | ||
+ | |||
+ | * There are many videos on youtube that give good visuals - me to provide link. | ||
+ | * Search the internet and soldering and teachiques. | ||
+ | |||
+ | A few things I found (will fix up later): | ||
+ | |||
+ | * Keep the sponge wet and cold. The tip is cleaned by the steam. | ||
+ | * Keep tip shiny. Heat transfers better (Maybe if it is black, it is too hot) | ||
+ | * Ensure good contact with both the board trace (word?) and lead. | ||
+ | * Around a second after contact, place a small amount of solder between the iron and the lead | ||
+ | * When you see a slight change in the material (melting, about 2 seconds after contact) push the solder into lead and trace hole on the opposite side of the iron. | ||
+ | * If your iron is on the joint for more than 2 seconds and the metal isn't flowing, take it off, clean the tip again and wait 10 seconds. Aim to have the iron on the board no longer than 3 seconds. | ||
+ | * You can use a metal clip to defuse some of the heat. Excessive heat for too long will damage certain components. (this is where the 2nd 3rd hand is handy - metal grips wire and defuses some heat) | ||
+ | * Lead's bad for you. Don't suck in too much. | ||
+ | * Go slowly, even one leg at a time for fragile components (although getting a little run going seems to work fine at times - it's just there won't be the heat defusing clip attached to all of them) | ||
+ | * After every group of solders, check, with a multimeter, every connection through to a common (same voltage - zero resistance) hole on the board. That is, in resistance mode, place a tip on the wire and the other tip on the connecting board hole via a trace. Check with the schematic to find appropriate testing points. | ||
+ | |||
+ | * While you are at Jaycar, buy 3 kits and practice your soldering. When you finish one and it is functional, then start on your core. | ||
+ | |||
+ | ==HOW TO USE A DIGITAL MULTIMETER== | ||
+ | |||
+ | * Again search youtube . me to provide link | ||
+ | * Black lead - in common port (COM) and to placed closest to the negative side of voltage source (Vss) or ground.{ Get confused about ss. Stands for source or electron flow (as opposed to conventional flow + to -) or surplus of electrons?? Source destination. or surplus and deficit/ | ||
+ | * Don't put the red lead in the amps socket (only the ohms and volt socket). Rarely check for amp and can do damage - only check current if you disconnect the wire you are testing the current so DMM is run in series with circuit. | ||
+ | * If you don't have a continuity tester that beeps then just use the resistance setting and test for close to zero resistance. | ||
+ | |||
+ | ==SOME BASICS IN ELECTRONICS== | ||
+ | |||
+ | * Read volume one of http:// | ||
