Greetings from Columbus, Ohio USA

Hello to all,
My name is John, N1CTF.
I just discovered this site and am very interested in providing radiation readings.

My primary project is a weather station kiosk, written in Java, that runs on an RPi4B with 7" display. It supports a J305 based Geiger counter.

My current projects are as follows:

I write a lot of code in Java, and have 8 RPi's running in my shop. My latest project is radiation monitoring.

Other projects include a homebrew quadcopter, that I use to locate transmitters using an RTL-SDR.

I also built a small tracked vehicle,with a PTZ camera, so my wife can observe me and talk to me and follow me around, using an app, that is still under development. It also serves as a test platform for various sensor development projects.

I also built a GPS disciplined oscillator with a 10 MHz time standard for my Motorola service monitor.

I also run an AREDN node, and Winlink2000 node.  Also a fixed Kerberos SDR server, for which I am currently building an antenna array.

For radiation monitoring, I wrote an interface that runs on an RPi3B, which reads clicks from a CAJOE J305 tube Geiger counter and provides the data as a TCP stream. The CAJOE and RPi mount in a box, located in the back yard, and is connected by an Ethernet cable using PoE. This is displayed on the weather station kiosk as microSeiverts per hour. Next I will write an interface to send this data to RadMon.

I have numerous other interfaces I wrote in native Java, such as an SGP30 gas sensor. Also, an interface to NASA DONKI for real time space weather reports from satellites, (such as solar flares and CME's, and 6 other event types). And also an interface to EPA AirNow API for particle pollution and ozone. And an interface to NASA Network Earth Rotation Service, so I can report the variation in the length of a day. I can actually tell you the length of a day to the last nanosecond. The earth is actually slowing down right now. One day, it will stop turning altogether. --- Just something to think about!  I can also tell you the exact, instantaneous angle and elevation of the sun, and the moon. So I can always know which way to look if I want to do some moon watching

I currently send radiation data to APRS and CWOP, however they do not have any way of using it.

I also have an Ecowitt WS-90 weather station, for which I wrote a native Java interface.

I also constructed a black globe temperature sensor, using an RPi3B, which also provides a TCP stream.

The weather kiosk sends weather and radiation data to APRS over VHF 2 Meter radio, and to APRS-IS and also to Citizens Weather Observer Program (CWOP), and it will soon send radiation levels to RadMon!

All my stuff is open source, written in Java, so I am glad to share if anyone is interested.

Thanks for reading this far!

Kind regards,

John,
