Introduction
Circuits can be made in many different ways:
- prototype board (e.g. perfboard or stripboard)[5]
- volumetric circuits[6][7]
- Etching a Printed Circuit Board (PCB)[8][9].
There are still other ways of making circuits, for example using the vinyl cutter to cut copper traces, using conductive fabric, etc. A nice overview of other alternative methods you can find at the great website of KobaKant: How To Get What You Want. Besides a lot of other interesting stuff (browse through it!!) the traces making sections you can find here: Kobakant section on Traces.
It is even possible to (almost) entirely knit your circuit: The Knitted Radio, Drapery FM.
In this lab you will be making a circuit with your preferred method with exception of the breadboard. The circuit presented here is a touch sensitive noise making circuit.

BOM
BOM or Bill Of Materials is common engineering language for list of components you need to build something. Our current BOM:
| Component | Label on schematic and board layout | Value | Has polarity (does the part orientation matter?) |
|---|---|---|---|
| IC | 555 | NE555 | Yes |
| Resistor | R1 | 220k (224) | No |
| Resistor | R2 | 10k (103) | No |
| Resistor | R3, R4 | 1k (102) | No |
| Resistor | R6 | 0R (0) | No |
| Resistor | R5, R7 | Do not mount (yet) | No |
| Capacitor | C1 | 10uF (dark brown) | No |
| Capacitor | C2 | 0.1uF (micro Fahrad) (brown) | No |
| Capacitor | C3 | 1nF (nano Fahrad) (light grey) | No |
| LED | Led1, Led2 | - | Yes (green dot (cathode) points down towards board edge) |
| 9V Battery Clip | VCC | - | Yes |
| Speaker | SPK | 8 Ohm - 16 Ohm | No |

Assignment
Choose a desired method to make the circuit and make it (work)! Try out different resistor values!
