PICbook - Embedded Design PIC18F452

Embedded Design with the PIC18F452 Microcontroller written by John Peatman (Prentice Hall, 2003) in support of Microchip Technology’s PIC18F family of microcontrollers.

The QwikFlash devlopment board is used as an example in the book for interfacing the PIC18F452 to various external components. The board contains varous I/O devices such as an RS-232 port (for program code development with QwikBug), RPG, potentiometer,a pushbutton, an LCD, and a few LEDs. A temperature sensor is included on the board to demonstrate the use of the PIC18F452’s A/D module. A two-channel D/A converter illustrates the use of the PIC18F452’s SPI three-wire interface.

“This centralized system can control almost all of the lights in my home, a few appliances, the garden irrigation, some window treatments, the Audio/Video system, the security system, and the HVAC (Heating Ventilation and Air Conditioning).”

Home Automation by Edward Cheung

“I can communicate with the central computer by using keypads throughout the house, any phone in the world (including those inside the home), any browser over the internet, and from my wrist watch. A webcam (with integral pan/tilt) allows me to see what is happening with nothing but a web browser.”

Sam has some wonderful Audio and Video circuits. He is from Greece the land of Mythology and the Gods. These are Electronic Circuits and DIY Projects for the hobbyist.

Sam Electronic Circuits

There is a huge collection of Valve or Vacuum Tube Power Amplifier circuits. Even Hi-Fi Preamplifiers based on these tubes. Power Supplies and Test Instruments you could build to power-up your Hobby Bench at low cost.

Sam Electronic Circuits

He has circuits for the Automobile and battery as well. Clock and Timer circuits for Home Automation. VU Meters and Graphic Equalizers to make your Audio dream project.

When i came online in the late nineties, i discovered Sam and other sites having many circuits and ideas. Ham radio folk were also in good numbers. That was an Innocent and Informative Web, it was heaven.

Sci.Electronics.Repair Frequently Asked Question(s) (or S.E.R FAQ for short) Home Page. This site features Samuel M. Goldwasser’s latest and greatest “Notes on the Troubleshooting and Repair of…” series of comprehensive repair guides for consumer electronics equipment and other household devices.

Technology Resource – Silicon Sam

There is also a great deal of other information of interest to the electronics hobbyist, experimenter, technician, engineer, and possibly even the dentist and poet. Included are the now quite comprehensive and massive “Sam’s Laser FAQ”.

Sam’s Laser FAQ has a great deal of information on a variety of laser and optics related topics including a comprehensive treatment of diode, helium-neon, argon/krypton ion, and CO2 lasers as well as amateur laser construction including numerous examples of truly home-built lasers. Much of this is not available anywhere else either on-line or in print!

This generates green light at 532 nm which is not a bad shade of green and quite close to the eye’s peak sensitivity. This is the approach used in modern green laser pointers and most modern DPSS green lasers. While other materials can be used to obtain other wavelengths (blue being the most common)
