A chassis mounting mains transformer with a voltage range of 12-0-12V and a current rating of 500mA. The transformer's primary winding is 230V, and the secondary winding is center-tapped. The transformer functions as a step-down transformer, converting 230V to 12V . It can be used in small rectifier circuits to charge a 12V battery, power small devices with low voltage ratings such as Arduino, PIC, AVR, Raspberry Pi, and other controllers, and charge mobile phones, among other things.

12-Stage Binary Ripple Counter IC - 74HC4040 The 74HC Series 74HC4040 IC is a 16 Pin 12-Stage Binary Ripple Counter IC having 2V to 6V Operating Voltage range with a 1uA low input current. It has a clock input (CP), an overriding asynchronous master reset input (MR), and twelve parallel outputs (Q0 to Q11). The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP. Each counter stage is a static toggle flip-flop. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC. Pinout: Pinout Of 74HC4040 IC

120mm Aluminium CPU Heatsink This is a 120mm Long Aluminium Water Cooling Block Liquid Cooler Waterblock Radiator-GPU CPU Cooling Heatsink.  The CPU heatsink has a solid construction and choosing aluminum as the raw material is a wise option for heat dissipation. It is ideal for applications in computer CPU, industrial inverter driver, laser head cooling, and industrial control cabinet cooling. The CPU heatsink is a water cooling block where the heat dissipation method os that the liquid conducts the cold and heat exchange. A water cooling block is the water cooling equivalent of a heat sink. It can be used on many different computer components, including the central processing unit (CPU), GPU, PPU, Peltier Module, and Northbridge chipset on the motherboard. Aluminum Water Cooling Block 40×120 is meant to transfer heat from one source into the liquid that flows around the water cooling block. Removing the heat from the graphic card into the liquid that runs through the water cooling block. There are two main types of GPU water blocks: full cover blocks and universal blocks for custom graphic cards Aluminum Water Cooling Block 40×120 is the best way to cool a CPU because water transfers heat much more efficiently than air. Liquid cooling also makes your PC run quieter because you won’t have fans constantly running at a high RPM. However, liquid cooling a PC can also be dangerous if water leaks onto hardware. Features: Material: Made of high-quality aluminum for excellent heat dissipation. Size: Measures 120mm, suitable for various CPU cooling applications. Compatibility: Compatible with a wide range of CPU sockets, including Intel and AMD platforms. Cooling Method: Typically used in conjunction with a fan to enhance cooling efficiency. Durability: Constructed to withstand high temperatures and provide long-lasting performance.

125kHz RFID Keychain (read) This is 125kHz RFID Tag. The RFID technology is used for sensing and identifying tagged people and objects for access control, automation, and a whole range of different applications. Operating on a frequency of 125kHz, these tokens are all pre-programmed with unique ID numbers to communicate wirelessly with RFID Readers over distances of around 10cm or less. This means you can attach it to vehicles or items, keyrings or even pets’ collars to keep track of the location via an array of readers in the office, warehouse or home. Each RFID Tag comes attached to a small keyring, within a little blue housing. This 125KHz RFID Tag makes them easy to distribute while maintaining a fair amount of discretion. Additionally, the process of matching tags to readers is also very simple as well, as all you have to do is tell the RFID Reader that you are adding a token, and then hold the token nearby. Then, when the token passes by the reader, the system can identify and log the ID number and time, or can even open up doors or other access ways automatically. This basic RFID tag works in the 125kHz RF range and comes with a unique 32-bit ID. It is not reprogrammable. This blank, smooth, and mildly flexible RFID tag is ready for your logo.
