  In this DIY project, we will explore how to build a data logger  using the X25020S , a 2-kilobit EEPROM  (Electrically Erasable Programmable Read-Only Memory) chip. The X25020S is an I2C-based EEPROM that can store small amounts of data, making it ideal for applications where you need to record and later retrieve data. We'll build a simple project where data can be logged from sensors and stored in the X25020S, which can then be retrieved later. This project is a good introduction to working with non-volatile memory, I2C communication, and designing data storage systems for embedded systems. The X25020S is widely used for storing configuration data, calibration settings, or sensor readings. In this example, we’ll create a temperature logger  that records temperature readings to the EEPROM at periodic intervals and allows the data to be read back when needed.   Components Required: ●   X25020S EEPROM  (2-kilobit I2C EEPROM) ●   Temperature sensor...

  In this DIY project, we will use the TC1044SEOA , a DC-DC inverter  chip, to build a negative voltage power supply . This project will help you understand how to invert a positive voltage to a negative one using minimal external components, which can be useful for powering circuits that require negative voltage rails. The TC1044SEOA is a small, efficient IC that provides an ideal solution for creating negative voltage from a positive supply. The ability to generate a negative supply voltage from a positive voltage is a common requirement in many analog and digital circuits. For instance, operational amplifiers often need both positive and negative supply rails to properly amplify AC signals. With the TC1044SEOA, we can create this negative voltage supply using simple components, which is ideal for compact projects where space and cost are critical factors.   Components Needed: ●   TC1044SEOA  IC (DC-DC inverter) ●   Capacitors  (10µF and 0.1µF) ● ...
