LibraryBox 2.0 by Jason Griffey Share this project Done Share Tweet Embed MCP4921 12 bit DAC interfacing with PIC16F877 microcontroller via SPI Connectivity In any real time project, MCP4921 12 bit DAC interfacing with PIC16F877 microcontroller via SPI Connectivity is very essential. Because in real world most of the input sensors and output devices are analog. So if we want to work with those we need to know the basic interfacing of those sensors and output devices with microcontroller. Here I give you tutorial project on “MCP4921 12 bit DAC interfacing with PIC16F877 microcontroller via SPI Connectivity”. Project description: In this tutorial project we will see how we generate triangular Wave using MCP4921 12 bit DAC.

5v This discussion covers a number of ways to generate 5v (and up to 10v) from 1 or 2 cells. It also covers how to get 5v from a number of nearly flat cells and generating a voltage from solar cells. Every project needs a power supply. DDNS – Free Dynamic DNS Providers We maintain the #1 list of Dynamic DNS (DDNS) providers online. Dynamic DNS is a method that allows you to notify a Domain Name Server (DNS) to change in your active DNS configuration on a device such as a router or computer of its configured hostname and address. It is most useful when your computer or network obtains a new IP address lease and you would like to dynamically associate a hostname with that address, without having to manually enter the change every time. Since there are situations where an IP address can change, it helps to have a way of automatically updating hostnames that point to the new address every time. Enter DDNS to the rescue. We are proud to be considered the top resource online for information on dynamic dns providers.

PIC18F4520: Serial Digital-to-Analog Conversion - Northwestern Mechatronics Wiki Since PIC microcontrollers do not offer analog outputs, a Digital-to-Analog converter (DAC) must be used to output an analog signal. An eight bit digital number can be converted to analog by using eight of the output pins from the PIC MCU to a separate DAC chip, however if more than one conversion is neccessary, this will quickly use up many of the available output pins from the PIC microcontroller, and require extensive wiring. Luckily, there is an easier and more effective way of doing this using I2C communication. I2C utilizes two lines to communicate, usually called SCL and SDA (a clock line and a data line). A "master" produces an I2C signal which is sent to the "slave" to work with.

EK MSI / Gigabyte Radeon R9-290X VGA Liquid Cooling Block Rev 2.0 - Acrylic (EK-FC R9-290X (Rev.2.0)) EK-FC R9-290X is a high performance full-cover water block for AMD reference design Radeon R9 290X and -290 graphics card. Please check our Cooling Configurator online compatibility system for detailed compatibility list! This water block directly cools the GPU, RAM as well as VRM (voltage regulation module) as water flows directly over these critical areas thus allowing the graphics card and it's VRM to remain stable under high overclocks. EK-FC R9-290X water block also features a very high flow design therefore it can be easily used in liquid cooling systems using weaker water pumps.

Using BlackSquare Enigma, no one can decrypt your confidential data - EVER! Every so often, a truly compelling and innovative product comes along that disrupts traditional technology in a positive way.

Embedded Systems/PIC Microcontroller Manufactured by Microchip, the PIC ("Programmable Intelligent Computer" or "Peripheral Interface Controller" ) microcontroller is popular among engineers and hobbyists alike. PIC microcontrollers come in a variety of "flavors", each with different components and capabilities. Many types of electronic projects can be constructed easily with the PIC family of microprocessors, among them clocks, very simple video games, robots, servo controllers, and many more. The PIC is a very general purpose microcontroller that can come with many different options, for very reasonable prices. Other microprocessors in this family include the Parallax SX, the Holtek HT48FxxE Series, and some "PIC-on-a-FPGA" implementations. History[edit]

Digilent Inc. - Digital Design Engineer's Source The chipKIT™ Uno32™ is based on the popular Arduino™ open source hardware prototyping platform but adds the performance of the Microchip PIC32 microcontroller. The Uno32 is the same form factor as the Arduino™ Uno board and is compatible with many Arduino™ shields. It features a USB serial port interface for connection to the IDE and can be powered via USB or an external power supply. Tor (anonymity network) Tor (previously an acronym for The Onion Router)[4] is free software for enabling online anonymity and censorship resistance. Tor directs Internet traffic through a free, worldwide, volunteer network consisting of more than five thousand relays[5] to conceal a user's location or usage from anyone conducting network surveillance or traffic analysis. Using Tor makes it more difficult to trace Internet activity, including "visits to Web sites, online posts, instant messages, and other communication forms", back to the user[6] and is intended to protect the personal privacy of users, as well as their freedom and ability to conduct confidential business by keeping their internet activities from being monitored. An extract of a Top Secret appraisal by the NSA characterized Tor as "the King of high secure, low latency Internet anonymity" with "no contenders for the throne in waiting".[7] Alice's Tor client picks a random path to destination server
