Cheap PIC Programmer
This programmer works only with PIC16F84 but it’s great because it never causes errors and works with almost all computers,unlike some other homemade programmers.
Step 1: Step one : Materials
So here’s what materials you will need:
-RS232(Serial) FEMALE connector
-BC547B or 2N3904 (I couldn’t find the BC so i used 2N3904,it works great)
-5.1 V diode
-100 uF 16V Electrolytic Capacitor
-Flashing red LED / 2.1 V Standard Red LED
-Scissors or any other cuting tool
-Hot glue gun]
Step 2: Step two : The scheme
As you can see , i tagged two connection in the scheme as “Optional point” one and two .
Those are the points where you will connect the “Optional” circuit i will show you in step 3
Step 3: Step three : The optional circuit
The optional circuit consists of the LED and 3.3 Kohm resistor marked as optional in step one.
One pin of the resistor goes in the Optional point one , the other pin goes in the anode(+) of the LED.
The cathone(-) pin of the LED will go in Optional point two.
If you don’t understand , use the ellipse marked area of the scheme below.
Step 4: Step four : Let’s build it !
Ok , you’ve got all you need.Now it’s time to build it.
DON’T CUT THE IC BOARD YET!
First solder the RS232 female connector in a corner of your IC Board.If you don’t know what are the connectors of the RS232 i uploaded an image.
After you soldered the RS232 , solder all elements according to the schematic,and then cut the board.
After you cut the board,secure all solderings with hot glue (optional).
