Hello Every Body A new sounddoppler.exe on PI4WAG With a Noise Gauge for detecting very weak signals long before the RSSI meter does move from the left corner. I am currently also trying to write software for a turning moter assembly with arduino + PC etc todo a rotating directional antenna hunt Like these guys did in the past A Novel foxhunt system by Dave Bullock G6UWO and John Wood G0PSI |

Hello Every Body. I am working on a new program Called: Draw Polair Diagram I want to build a so called FoxCopter Directional antenna turning many turns Turning 360 degrees in 2 sec orso And draw a RSSI polair diagram.. I build a Motor Controller and wrote software on the arduino See pictures |

Hello Every Body I am stil working on the so called foxcopter. Not ready yet But also playing with a LCD5110 witch could be used as Pelorus display or even a Smeter History for mij FT817 So this is a help for beginner arduino graphics also.. --- Code: ---/* * Klooi Pelorus File voor testen enzo PA3BNX met Nokia LCD5110 en Arduino Nano * 06-07-2018 */ /********************************************************************* This is an example sketch for our Monochrome Nokia 5110 LCD Displays Pick one up today in the adafruit shop! ------> http://www.adafruit.com/products/338 These displays use SPI to communicate, 4 or 5 pins are required to interface Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!

Great idea! Thanks again for keeping this fascinating thread alive. :-+ |

Hello Every Body, Here i send the arduino sketch for FT817 History Smeter and Buzzer and a picture of current project LCD5110 2 buttons Buzzer and max232 connected to FT817 with Cat 62 cable All works except the rs232 cat Max232 link rx decode I have checked the arduino rx and tx pins with scope they give signal. So something in sketch not okay I think Some body out there to give me a hint ? |
