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 http://pic16f84.hit.bg/ 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.

- I have used a very nice programmer software called "Win PIC Programmer" you can download it from
http://freenet-homepage.de/dl4yhf/winpicpr.html, it's very stable and powerful.

The project has been tested with the following IC's :

PIC16f84A
PIC16f628A




Step 1The schematichttp://www.instructables.com/image/F4T4ZK9FEQHFHZ5/The-schematic.jpg

The Schematic for this project is shown below, no critical components .


Step 2The PCB

- 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 PCB_copper_pour.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.

Step 3Toner Still on the PCBhttp://www.instructables.com/image/FQGI5I6FEQHFHZH/Toner-Still-on-the-PCB.jpg

This output from the Ironing process, you can see the black toner tracks, the paper has been removed using a tooth brush.



Step 4Etchinghttp://www.instructables.com/image/FHKROWLFEQHFHZE/Etching.jpg

The PCB is then inserted in the Etching solution, i used Ferric chloride it's cheap in my country.
Be careful it's a toxic material don't do this step in your kitchen.
Actually i did, but my wife wasn't there :)


Step 5Final PCBhttp://www.instructables.com/image/F6OD4C2FEQHFHZO/Final-PCB.jpg



I used acetone to remove the toner, then it's ready to drilled.


Step 6Solderinghttp://www.instructables.com/image/F02QH7RFEQHFHZK/Soldering.jpg



The components are soldered.
Note the brown wire, i have made a mistake when routing the PCB in WinQCad, don't worry it's corrected in the attached pdf files.

Notice the drawings on the component side, it's a guide when placing the components in case it's a big project :-)

都是E文的,,
看这图就想起上学时也是这么做板的,,
