Recently I found on eBay a cheap ADC for about 6$ . It has 10 ADC channels and 12 bit resolution , with an integrated onboard CH340 serial port to USB port chip, which enable to read results directly on a serial line of a computer , using 115200 baud speed. As You can see […]
In recent years, technology has made leaps forward in small handheld or laboratory GPSs such as those created for the NEO UBLOX series. I recently bought a NEO M8N, which itself mounts a programmable TCXO. It is indeed possible to connect the NEO module to a serial and program it with the U-Center program , […]
https://github.com/yxie-git/allantools You can use this great tools on GitHub to create frequency/time stability graphs looking similar to Stable32 Software. Is written in Python using Matlab libraries .
Following the article on the radio solar bursts received on the decameter band during last few years by our Sidmonitor website i decided to publish two spectacular geomagnetic pulsations received with Forno ELF Observatory, sited in Forno di Coazze , Torino, Italy . (OPERA Network) For more references you can also see my previous works […]
I decided to publish here, after few years , the most spectacular solar bursts in the decameter band captured by our Sidmonitor (The commemorative website has been moved to http://sidmonitor.rf.gd ) solar spectrometers observatories , now permanently closed. Forno, in the Western Alps and Pasturana, in the plain of Alessandria. The two old live web-pages were […]
It is not easy for me to start this full article, as it collects about a couple of years of technical work conducted with other friends . I decided to divide this work into three parts. A first part made by Jan Jozef Oksiuta (VK4EBP) from Australia, a second that follows some old works done […]
I’ve tried to create a program that could calculate the linear phase of the 50 Hz mains in real time. Although there are online excellent Windows software such as Stable32 from Hamilton Technical Services and John Miles Timelab I needed a program running under Linux/Unix and Python. Luckly there was an online library that came […]
This will be the first part of a larger project that will include other friends that have collaborated with me directly or indirectly this last year. It was in many ways, a funny and interesting project to follow. All schematics, codes and results are free for use , please just give references to authors. USE CAUTION […]
Recently, while playing with the USRP2 unit and a i3 processor here ,I met this unpleasant issue of packets dropping , the screen comes quickly saturated by the letter “D” when recording . From Ettus Network-based devices: The host does not back-pressure the receive stream. When the kernel’s socket buffer becomes full, it will drop […]
Introduction This new project is added to Sidmonitor site , with Claudio Re and others friends , we have developed in last few years. Having Ionograms updated from Cyprus gives a good point of view on current state, the conformation and deformation of the ionosphere caused by natural phenomena such as solar active regions and […]
