I have built this project to burn my small PIC's This is a serial programmer works on the RS232 ( PC serial port ), known as JDM Programmer, thanks to the site which contains the schematic and the programmer software. The programmer is powered from the Serial port itself, so there's no need to any external power supply. But be careful this circuit will not work with the Laptop Serial port due to the weak voltages it has.

Use your 60hz sine pwm code pic 16f628a skills and start making money online today! Freelancer is the largest marketplace for jobs in the world. LED Chaser for PIC16F84A and 16F628A. This simple circuit functions as a 12 LED chaser.

I have used a very nice programmer software called 'Win PIC Programmer' you can download it from it's very stable and powerful. Ps3 emulator software free download. The project has been tested with the following IC's: PIC16f84A PIC16f628A Step 1: The Schematic. I have made the PCB using WinQcad Software it's easy and has a nice autorouting feature. Please download the PDF document which contains the true scale dimensions. You will see two files: PCB.pdf and PCBcopperpour.pdf the second one has a 'mass copper pour' to save your etching solution and to speed up the etching process without affecting your tracks.

I used the Toner Transfer method draw the tracks, i can say the output is nice. I have included the steps required to make PCB in the following steps.

You bought the wrong type of connector from Amazon - you have to remove it. The female and male versions don't have the same pinout because one is the mirrored version of the other.

So you;ve connected pin1 to pin5, pin5 to pin1 etc. Alternatively to using the null-modem cable you can solder not a connector but coloured wires to the programmer board and then solder a female connector (making sure pin numbers match correctly) on the other end of those wires. Then you would plug the female connector directly into the COM port of your PC. Don't make the wires too long though. This works - I tested it.
