In this workshop, we cover 3 things
-How to solder
-How to document your circuit on breadboard and design your PCB
-How to mill a PCB
Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal. (from wikipedia)
Here is a very nice tutorial on how to solder
And Here are some video tutorial on different types of component soldering
Breadboard to PCB
Please download fritzing software from
The components comes in different packages. The same components (part number) in different package functions the same way. The package (shape) of the components does not define what it is. 3 legged black thing does not mean Transistor!
TIP122 Darlington Transistor
7805 5V voltage regulator
“Through-hole technology, also spelled “thru-hole”, refers to the mounting scheme used for electronic components that involves the use of leads on the components that are inserted into holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side either by manual assembly (hand placement) or by the use of automated insertion mount machines.” (from wikipedia)
SMD (surface-mount device)
“Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD).” (from wikipedia)
PCB is a short name for Printed Circuit Board.
You can make PCB in various different ways and techniques.
The most common DIY way is to etch the copper layer with chemical.
You can buy the copper board with photo sensitive material and expose it with circuit image to UV light, like silkscreen making.
or there is a DIY way to use transfer paper and iron or hacked laminator.
You can also mill the circuit with CNC milling machines
below image is a cnc milled circuit with voronoi design.
You can also commercially produce PCB. there are various services to print your circuit, not only 1 layer but on multiple layers. In general, you need to provide gerber files to the company printing your circuit.
There are also flexible PCBs which you can print commercially or etch it yourself.
you can also make circuit out of copper foil and vinyl cutter
you can cut copper conductive fabric with laser cutter and make fabric circuit.
