LM317T Voltage Regulator with Pass Transistor

Model No. 15A:- The main objective of the project is designing an automatic washing machine for programmable sequential switching of motors using embedded system based micro controller concept. The development of this application requires the configuration of microcontroller architecture that is the selection of the machines, and writing debugging of the application program. In this project, the clock plays an important role, where it is used in the following mode ie, the set mode, auto mode and manual mode for controlling different machines. In set mode, through the digital clock the machinery will run based on/off and on time where as in auto mode they will run by default settings and finally in the manual mode the real-time systems. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

with Henry Zhang, Applications Engineering Manager - Power Products video.linear.com Current sharing performance is critical for PolyPhase® DC/DC converter to balance the thermal stress and properly size the power components. The PolyPhase converter can be controlled by either voltage or current mode control scheme. With voltage mode control, the active current sharing is achieved with a complicated external current sharing loop, which is usually slower than the inner voltage feedback loop. With current mode control, such as implemented in the LTC3731 or LTC3850, the current sharing can be implemented very easily with its fast current loop.

The EZ-B Robot Controller was designed by Canadian Roboticist DJ Sures, who is the creator of popular robots: Autonomous Wall-E, Award Winning 3-D Environment Mapping K-9 and the Autonomous Cookie Monster. Combining his robot knowledge and experiences, the EZ-B was designed as an all-in-one solution. The circuit board contains a powerful voltage regulator, a bluetooth antenna module, digital I/O, ADC, servo control, serial ports, MIDI connection, TellyMate interface, and more! This robot controller supports the EZ-Builder software interface to control your robot, without even needing to program! Watch the EZ-Builder Video and see how easy it is to add Camera Color Recognition to your robot without writing any code! For those interested in programming, the .Net EZ-SDK exposes the EZ-B features. Including color camera recognition, voice recognition, voice synthesis, midi control, and more. You can quickly recognize how the EZ-Robot Project was designed for reusable flexibility. Build many DIY Robots with a single EZ-B Controller by simply moving the board between projects.

This is an 8-bit ALU that I created by connecting two 4-bit ALUs together. There are 48 plus a few more operations available (I don't know how to use the comparators). There are 16 logic functions and 32 arithmetic operations. Components used (excluding the voltage regulator): 2x 74LS181 - 4-bit ALU 1x 74LS04 - Hex Inverters 2x 8 position DIP switches 1x 4 position DIP switch 1x 2 position DIP switch 9x LEDs (1 Green, 8 Red)
