LM7806 Voltage Regulator
The LM7806 belongs to a sort of three terminal positive regulators, available in the TO-220 package and with several fixed output voltages that makes them useful in a wide range of applications. The LM7806 is monolithic fixed voltage regulator integrated circuit, suitable for applications that required supply current up to 1 A. Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.LM7806 is a member of fixed linear voltage regulator ICs. The voltage source in a circuit may have fluctuations and would not give the fixed voltage output. The voltage regulator IC maintains the output voltage at a constant value.

Thermoelectric Cooler Peltier Module TEC1-12715 12VDC 15A Cooling Refrigeration Plate
Thermoelectric Cooler Peltier Module TEC1-12715 12VDC 15A Cooling Refrigeration Plate
The TEC1-12715 40x40mm Thermoelectric Cooler 15A Peltier Module is the simple application of the Peltier Thermoelectric Effect. A thermoelectric cooling (TEC) module is a semiconductor-based electronic component that functions as a small heat pump. By applying the DC power source to a TEC, heat will be transferred from one side of the module to the other. It creates a cold and hot side. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature differential to generate electricity. This Heat Sink Thermoelectric Cooler Peltier works very well as long as you remove the heat from the hot side. After turning on the device, the hot side will heat quickly, the cold side will cool quickly. If you do not remove the heat from the hot side (with a heat sink or other device), the Peltier will quickly reach stasis and do nothing. We recommend using an old computer CPU heatsink or another water block of metal to pull heat from the hot side. We were able to use a computer power supply and CPU heatsink to make the cold side so uncomfortable we could not hold our finger to it. They are widely used in industrial areas, for example, computer CPU, CCDs, portable refrigerators, medical instruments, and so on

Thermoelectric Cooler Peltier Module TEC1-12706 12VDC 6A Cooling Refrigeration Plate
A thermoelectric cooling (TEC) module is a semiconductor-based electronic component that functions as a small heat pump. By applying a dc power source to a tec, heat will be transferred from one side of the module to the other. It creates a cold and hot side. Using this TEC TEC1-12706 Thermoelectric cooler or thermoelectric Peltier get ice cold in minutes or heat to boiling by simply reversing the polarity.TEC12706 Cooling refrigeration Plate used for numerous applications from CPU coolers to alternate power sources, or even for your own custom car drink warmer/cooler. Since they consist primarily of semiconductor material sandwiched between ceramic plates and have no moving parts. These devices must be used in conjunction with a heat sink water block to avoid burned one side is cooling (Printed model number)and another side is heating (Printed no word) when working. Please radiating the heating side
Note:
Power on the device only with the proper heat-sink setup to avoid any burning/damage or malfunction of the device, use a fine heat sink (such as in CPU fans) with thermal paste, and power the device. Use a 12v dc power supply to power the tec1-12706. Use one aa battery for 10- 20 seconds to power on the device to find the hot /cold side
