Links to electronic circuits, electronic schematics, designs for engineers, hobbyists, students & inventors:

PIC NiCad Battery Charger - This cheap and easy to build NiCd/NiMH Battery Charger is suitable for automatically charging a wide range of batteries for many applications. Proper chargers are usually expensive and cheap chargers supplied with the original equipment often incorrectly charge the cells and dramatically shorten their life.....(added 10/05)

PIC Pages Tutorial  - It is, however, most vital for designers of embedded control products to select the most suitable controller and companion devices. Embedded control products are found in all market segments: consumer, commercial, PC peripherals, telecommunications (including personal telecom products), automotive and industrial. Most embedded control products must meet special requirements: cost effectiveness, low-power, small-footprint and a high level of system integration. ….(electronic schematic added 11/08)

PIC Phone Line Controller v2 - This is a newer version of previous device with a single relay. This one can have up to 6 relays and 6 sensor-state inputs. The task was to build a device that connects to the phone line and has a relay as an output switch. It should also sense if the connected «consumer» is turned-on or off and report to the administrator at the other end of the phone line. The administrator would then call-in the device, log in with the password, and check the state of «consumer», turn it on or off, change password or some other settings. ….(design added 11/08)

PIC PIN / PORT Extender  - This circuit based around 74LS154 will extend PIC / AVR microcontroller output PINs from 4 to up to 16. It can also be used for extending parallel port output pins. ….(circuit design added 11/08)

PIC plots pixels sans controller  - 02/16/98 EDN-Design Ideas  / (added 2/06)    

PIC Programmable Security System - This project uses the 12F675, it was chosen because of its low cost, A/D convertor and flash memory. This security system was designed….(added 08/08/08)

PIC Programmer - to download programs into PIC microprocessors. (added 7/03)

PIC Programmer (Michael A. Covington) - The project presented here will provide you with the ability to program a PIC from your parallel printer port on your PC computer. To program a PIC is relatively simple. A standard 5 volt DC supply voltage is connected….(added 05/08)

PIC Programmer 2 - (electronic circuit added 7/03)

PIC Programmer sent by FcoArroyo - Francisco Arroyo Garcia sent this schematic as an alternative to program MICROCHIP PICs. This programmer is a JDM-based and works fine to program the PIC 16F628A. (design added 12/06)

PIC Project #1   RS-232 to I2C Interface - (electronic circuit added 7/03)

PIC Tock Video Clock - (electronic Circuit diagram added 03/03/03)

PIC vacuum fluorescent display interface - (electronic circuit added 4/05)

PIC Web Server Schematic - (schematic / circuit added 05/06/07)

PIC12c508 Night Light Saver - (circuit added 7/02)

PIC12C508 Phase Controller for 2kW heater - (electronic circuit added 7/03)

PIC12C509 Gym Timer - (electronic circuit added 7/03)

PIC12C509 Logic gate Replacement for Nitrogen Filler - (electronic circuit added 7/03)

PIC12F675 - Flashing LED - Simple little circuit for testing PIC12F675 microcontroller. When you start learning a programming language like C++, Visual Basic or any other language your first step is to write a program that displays "Hello World" on a computer's monitor. When you start learning how to program PIC microcontrollers an equivalent to that is blinking a LED. ….(electronic schematic added 11/08)

PIC12F675 PIN PONG - This project is based on ideas from Rickard's electronic projects page and David B. Thomas VCR Pong. However, I have developed the simplicity even further, eliminating most of the external components. Using microcontrollers with internal 4MHz clock generator there is no need for the xtal. The 12f675 part also operates on wide voltage range, and the regulator can be removed. For game controller, I plan on using the old Commodore 64 style paddless. They include firing buttons, which I plan on using as power switch and game reset. 16F675 has a low power sleep mode with 1nA current consumption, so I plan on using that to switch off. ….(circuit design added 11/08)
