(From the September 1998 Radio Electronics)

First off, let me preface this by saying that I didn't name this. Even though they claim that it is a "No Part" project, it still requires a few parts. I recommend using a 12 volt DC supply with a voltage regulator for the +5 volt DC supply.

• IC1 - PIC16f83, PIC16c84, or PIC16f84 Microcontroller
• D1, D2 - 1N914 silicon diode
• Q1 - 2n3404 NPN silicon transistor
• R1 - 4700 ohm
• R3, R3 & R4 - 1000 ohm
• R5 - 2200 ohm
• All resistors are 1/4 watt, 5% tolerance
• C1, C2 - 0.1 microfarad ceramic disc
• J1 - DB25 male connector

How to Use It (not finished, yet)

1. Plug it into your printer port
2. Load the NoPPP program
3. Load the PIC hex file
4. Program the PIC
5. Verify that PIC is Programmed correctly
6. You're DONE!
