Heat Sink x 2:
It’s an Intel E97375-001 Socket 775 Aluminum Heat Sink Fan.
It's a PC processor fan, to keep the solution/medium at normal temperatures and to cool the resistors.
In this case, we are using 2 of them.
Specifications:
- Aluminum heat sink
- 3.5-inch (90 mm) fan
- Power input: 12VDC, 0.60A
- Supports Socket 775 CPUs with 65W TDP
Beaker x 2:
A cylindrical container, which will contain the medium/solution.
Their capacity will range from 250ml to 400ml.
Small Water Pump x 1:
A water pump, to pump the solution across containers. It will use up to 5v~3.3v.
We will be using a simple handmade water-pump, which uses the following materials:
- Silicone Glue, as a Sealant
- A Small Capsule, about 3cm of diameter and 4.5cm of height
- A tiny Electrical Motor, enough to fill in the Capsule
- Rotating Blades, little enough to fit in the motor's axis
- Transparent Tube, About 0.5cm~1cm diameter and small thickness
LCD Display x 1:
We will use an LCD to display temperature and relevant data.
Its an 16x2 liquid crystal display.
It can display White text, and has a Blue background.
It's specifically a 16x2_KST1602B-W.
It employs a HD44780 parallel interface chipset.
Dimensions: 84 mm x 44 mm. And Uses About 5v.

UV LED x 4:
We are using UV LEDs, so they can expose the GFP reporter.
Features:
- T1 3/4 5mm clear lens
- 395-400 nm
- 100-180 mcd
- Voltage drop 3-3.6V operation

Adapter AC/DC wall-12VDC 2A x 1:
This will be our source of energy regarding the Micro-Controller and everything connected to it.
Can revieve input Voltage of 100 to 240VAC.
AG2412-B281(2A0F) Datasheet: http://www.phidgets.com/documentation/Phidgets/3024_0_Product_Manual.pdf
Adapter AC/DC wall-9VDC 650mA x 1:
This will be used as source of energy, in case the AC/DC wall-12VDC malfunctions.
It's also to replace the amount of amperage, if it turns out to be unnecessary.
Can take input Voltage of 100 to 240VAC.
Temperature Sensor Probe x 2:
Its a DS18B20 Programmable Resolution 1-Wire Digital Thermometer.
We will use this probes in order to measure the temperature of water.
Its power supply range is 3v~5.5V.
The temperature it can read, ranges between -55°C to +125°C (-67°F to +257°F).

Datasheet DS18B20: http://datasheets.maximintegrated.com/en/ds/DS18B20.pdf
Small Buttons x 4:
It's an AU-101.
Can take 12 Vdc, 50 mA, and has 4 terminals.
We will use this buttons, in order to interact with the LCD or Actuators, and Sensors.
Red & Black Tinned Wire x 2:
We will use at least up to 2m~4m to cover all connections, with both of them.
Resistors x2:
We will use resistors, in order to heat the medium or solution.
Can take up to 100~120v.
Relays x2:
This relays, are used to control the resistors without making contact with the Arduino.
Since it would burn it's circuits instantly.
Can take up to 100~120v, and uses at least 5~9v.
