On this page you will find brief describtion of some of my hobby projects which are mostly based on a PIC processor.
Currently available pages: (Some pages are in Dutch)
Een GPS to APRS encoder using a PIC16F628 microcontroller. Uses the internal DA convertor to generate the AX.25 signal using a software DDS.
Advanced timer/controller for ARDF Transmitters
Time Driven Random number generator for outdoor games
My home-brew 8 channel software logic analyser, uses a pic18F252(5) as capture device.
A simple device using a pic 18F819 which can be used to determine the capacity and discharge graph of any rechargable battery.
Create an SSTV test signal with a single PIC microcontroller
Small circuit to record the frequency over some time
Electronics Goldmine sells the FAX display (as 1 16*1 display). You will find a short description of how to controll the other parts of the display as well.
A PIC driven IR remote which skips 1 or 7 minutes on my Harddisk Recoder
A PIC driven audio recording using a serial Flash chip to record audio from APT satellites
A PIC driven audio recording using a serial Flash chip to record audio from APT satellites
A standalone 500kHz transmitter for WSPR, QRSS and CW beaconing.
A CTCSS tone generator, intended to be used in an FT290R tranciever.
DTMF tone decoding in software with a 16F629 or 16F628A
