Day 1 - Introduction to Soldering and making your 5V power supply

The calss began with safety procedures and an exam about it

Basically, the safety procedures can be summarize as
1. Follow/listen/obey the instructor
2. Don't hurt yourself

Later, we began our first soldering practice in a different room

The result are:

 General procedure for soldering is
1. Clean up the soldering iron
2. Insert surplus into the holes(pads) and bend out the lead so it stays in place
3. Trim the lead and put some flux on
4. Put some solder on the soldering iron
5. Touch the solderin iron to the pad and the lead with the solder under the tip of the iron
6. Hold for 1 second so the solder can flow properly
7. Clean the pad with alcohol


A GOOD connection convers the pad without touchin toher pads and surrounds the lead
and with a shining color

For example :

Second part of the class is to do the power supply
First, we needed to practice wire splices (even I didn't do it)


After we were famalir with the wire splices
we were need to make the 5V breadboard power supply

Result:

The general procedure are
1. Get a AC adapter and two 2~3 inches long wires that were striped with a color of red and black
2. Chop off the plug at the end of its wire
3. Take out the outer layer of the wire and pull the conductors apart few inches away from each others
4. Strip the two conductors with red color wire is the positive and the other one will be negative
5. Solder the wire with the conductor with the correct color. Red to Red, Black to Black
6. Put head-shrink tubing on each of the conductors and heat it with the soldering iron



At the end of the class we were told to make a blog for what we did for the class that day

So Here is the blog :D
