Underground locator generator for Radiodetection using PIC16F628

Introduction I obtained an early vintage Radiodetection® RD400 "LLTS" Precision Line Trace unit for a very low price through eBay. The RD400 is the receiver portion of a transmitter/receiver pair that comprise an underground cable locator system. Because the matching transmitter was not available (hence the low price,) I had to design one that matched the two audio frequencies detected by the receiver. "LLT ...

RDS/RBDS decoder with optional FM stereo receiver using PIC18F452

This project supports both RDS (Europe) and RBDS (USA) Tuner FM band 88..108 MhZ (Europe and USA.) You can choose between a 4x20 character LCD or a smaller graphical LCD to display data. A simple  RS232 interface can also be used. A 4x20 character LCD module will display these: 1st row: Station name (PS), Quality, Program Identification (PI), Traffic Program (TP) and Announcement (TA) 2nd row: Time and Date ...

Infra-Red Transmitter using PIC12F675 microcontroller

Description This project uses a MicrochipPIC microcontroller and an Infra-Red LED to act as a PC controlled cable TV changer. Operation The purpose of this is so that my MythTVPersonal Video Recorder (PVR) can change channels on the cable TV set-top box when making a recording. A very simple program on the computer sends the channel number over RS232 to this PIC based IR transmitter which creates the correc ...

Prometheus/Pandora’s Box using PIC12C508 microcontroller

Prometheus/Pandora's Box Some of you monkeys out there think you can PWN me. You need to be Spanked. Here is an obfuscated ultraminimalized Monolith for you. It is enlightening and harmless, except to the devil, who really hates it, because I'm letting you have it (for "free"). You're curious. So Make it, if you have tools. GET PARTS This is easy. You need: -a PIC12C508 or 509 or anything compatible or be a ...

Hidden Radio Transmitter Controller

PicCon is a PIC microcontroller based radio controller designed for hidden transmitter hunting. When combined with a radio transmitter, it will produce tone sequences and Morse code messages at user-programmed times. It is completely field programmable via DTMF tones, utilizes EEPROM for all programmed options so they are remembered when power is removed, and is quite compact. PicCon interfaces to a radio t ...

PIC16F84 Based Morse Code Reader

So you want to become a HAM, or you've got one of those no-code licences, but like me feel somewhat lacking,... not having obtaining that age old badge of proficiency that differientiated the HAM from other radio operators. However, like thousands and thousands of others, you have trouble learning the code. The problem for most people is the non-real time nature of the process, i.e., writing down the last c ...
