RCD Programmer
Posted on Tuesday, March 30, 2010   •   Category: PIC


I believe that the "JDM Programmer" is cheap and very useful PIC Programmer. However, since "JDM Programmer" cannot control VDD, the algorithm "VPP before VDD" is inapplicable. Programming to the latest device from this reason may go wrong when using CONFIG settings as "Internal oscillator" "MCLR OFF". These devices are given power from the "JDM programmer",and execute program code. An error may come out by verification, or it may become impossible erasure and become impossible re-programming . In order to solve this problem, I designed a programmer based on the "JDM programmer." Since this programmer was made of resistors, capacitors, and diodes, I named this the "RCD Programmer." "Hardware settings" of IC-Prog are the same as the "JDM programmer."


RS232 Serial Port PIC Programmer
Posted on Tuesday, March 30, 2010   •   Category: PIC


PIC Programmer is an essential tool if you wish to learn or build projects with Microchip PIC Micro Processors. This serial programmer is for those who do not have a Parallel Port on their PC. Programmer may be used with PIC PROGRAMMER Professional Serial programming software from Oshosoft or other serial programming software.


PICkit2 Compatibile MPLAB Programmer
Posted on Friday, March 19, 2010   •   Category: PIC


This is a PICkit 2 MPLAB compatibile Programmer. It is a low-cost development tool with an easy to use interface for programming and debugging Microchip’s Flash families of microcontrollers. The full featured Windows programming interface supports baseline (PIC10F, PIC12F5xx, PIC16F5xx), midrange (PIC12F6xx, PIC16F), PIC18F, PIC24, dsPIC30, dsPIC33, and PIC32 families of 8-bit, 16-bit, and 32-bit microcontrollers, and many Microchip Serial EEPROM products. With Microchip’s powerful MPLAB Integrated Development Environment (IDE) the PICkit 2 enables in-circuit debugging on most PIC microcontrollers. In-Circuit-Debugging runs, halts and single steps the program while the PIC microcontroller is embedded in the application . When halted at a breakpoint, the file registers can be examined and modified.


70V PIC Voltmeter Amperemeter
Posted on Friday, March 12, 2010   •   Category: Test and Measurement


This PIC Voltmeter Amperemeter was designed to measure output voltage of 0-70V with 100mV resolution and 0-10A current with 10mA resolution. It is a perfect addition to any DIY laboratory power supply, battery chargers and other electronic projects where voltage and current consumption must be monitored. The heart of the meter is PIC16F876A microcontroller with built-in analog to digital converters and 2x16 green backlighted LCD display. Circuit design uses very few external components making it possible to fit this handy meter on a small PCB.


USB FM Transmitter MAX2606
Posted on Friday, February 19, 2010   •   Category: FM Transmitters


This MP3 Player FM transmitter can be used to listen to your own music throughout your home. The transmitter circuit use no coils that have to be wound. When this FM transmitter used in the car, there is no need for a separate input to the car stereo to play back the music files from your MP3 player. This FM transmitter use a chip made by Maxim Integrated Products, the MAX2606. The VCO (Voltage Controlled Oscillator) in this IC uses a Colpitts oscillator circuit. The variable-capacitance (varicap) diode and feedback capacitors for the tuning have also been integrated on this chip, so that you only need an external inductor to fix the central oscillator frequency. The supply voltage to the IC should be between 2.7 and 5.5 V, the current consumption is between 2 and 4 mA.
