| + | * One thing I reckon you shouldn't do is expect to have something done quickly. Sure there is a good chance it may happen first time but also just as likely there will have to be some sort of troubleshooting. With this being said, it would be wise to go through the entire links of the [[http://www.midibox.org/dokuwiki/doku.php|Midibox.org]] page. I say this because when you are on the verge of completing something, the last thing you want to do is spend days sifting through info so you end up doing what I have done and jumping on the forum and asking silly questions. So expect slow turtle and do the reading now. Know that there is a lot of reading a learning to do. Conversely there also needs to be a balance between reading and doing. So perhaps do what you can but if you can't do, expect to read for days/weeks. | ||

| * 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) | * 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. | * After every group of solders, check, with a multimeter, every connection through to a common (same voltage - zero resistance) hole on the board.

| * 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/deficiency or electrons ??? Or charge?? Will have to reread some more text books.} | * Black lead - in common port (COM) and to placed closest to the negative side of voltage source (Vss) or ground.{ Get confused about ss.

| * 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. | * Don't put the red lead in the amps socket (only the ohms and volt socket).
