  1. I went back and re-read how your set up works, that combination of mechanical and electronic is fascinating, I could not have come up with that myself. Is it all working as expected now? Did you leave it on 24 hour per .jpg? It has been a bit of a heavy work week so unfortunately I have not done a whole lot myself. Yesterday I sat down and amended the Arduino code to measure the minimum signal strength at the same time as I am currently measuring the average. The idea is that the transmitter should be detectable anyway however sudden jumps in signal strength due to noise from lightnin
  2. Miles Dyson didn't quite appreciate what he had built in that film so be careful if you try and switch it off..! * That is weird, I wonder why that happened? The light on the MKR flashes every time I take a measurement when running under USB power, but when under external power flashes once as expected and then stays on permanently. I have added the command to turn it off but it does exactly 3/8 of nothing... With work over the last week or so I have not done that much, but I got round to checking the data today. Helpfully the transmitter is back up and running after that inter
  3. Hi, Thank you for posting that is really useful to know, your plot looks similar to mine. So I think my radio is working properly but the transmitter isn't. I have turned logging on again so will see how this pans out. Thanks, David
  4. The code change has worked, analysis with Mk 1 eyeball seems to suggest a smoother output, time will tell if that also smooths out real events. Although I am not entirely keen on the plot today; I hope that a) the transmitter has been offline for an extended period rather than b) something is wrong with my radio...
  5. The transmitter seems to be down today so there is not much to see. As a result I have been making some code changes instead. I have simplified it by removing the alarm and pin interrupt. When I have finished taking measurements/sending to the MQTT broker I check the time and the number of seconds past the minute, subtract from 60 and send the Arduino to sleep for that amount of time. Not sure why I have not thought about this before, I think the low power library used with the MKR 1010 is a bit more flexible and the sleep time is variable. I have also changed how I am sampling da
  6. Hi, That is where I went, I looked around in the UK but went for the one I found on Ebay. Seller was really helpful, I bought a block and the optical grease and with p&p it came to about £40. I did however get stung £14 for import duty. Dave
  7. Activity so far today seems more stable. Dave
  8. Hi, The last week has been pretty quiet, yesterday there seemed to be quite a bit of activity with the transmitter going on and off, and a few days before that the signal strength seemed to jump somewhat but is back down again. There was about half an hour on the 27th from about 18:30 when I stopped receiving data at IoT hub but I will just keep an eye on that, 35 minutes over about three weeks isn't too bad. I have been tinkering a bit with Azure behind the scenes but otherwise not so much on the radio. I might change the sampling when I make a measurement as I take 1000 over the
  9. I am not saying that it is all perfectly matching but having loaded the last 24 hours of GOES data more than a few of the downward ticks in my VLF data correlate with a spike in X-ray flux...
  10. Thanks for posting your data. I am not quite sure what that hump is I was getting between about 16:00 and 19:00 is but I am not sure it was a flare - the sharp end of day peak does match what you got. Today seems more settled too (there seemed a lot of transmitter downtime yesterday); Over the last couple of hours I have noticed a few downward ticks in the line though that happen around jumps in the GOES data. Though they do also tally with apparent temperature jumps in the project box that the Arduino is enclosed in...
  11. Cool, am interested to see what was detected by your system.
  12. Just had a quick look at the dashboard while passing (I am not obsessed) and the end of day peak appears to appearing several hours ahead of normal. I pulled in the last few hours of NOAA data and there is something happening at the moment - the start of the peak was ahead of the event but there is something happening, even if it is small. The start of the peak does coincide with a jump in temperature up in my roof (first screenshot) thinking back the weather changed abruptly and went from being cold to full sunshine. I don’t know if that would explain the earlier par
  13. Hi, Looking good, is the new timing unit working as you hoped? I have noticed a few sudden drops in signal strength myself so had wondered if the transmitter had stopped transmitting momentarily. And that peak is interesting, very regular, very abrupt and yet not obvious what it is..? There was a C class flare yesterday but I did not register it, I don't know if that is because the radio is not sensitive enough or if it was pointing away from Earth. But it is good to know that some solar activity is happening. I used the NOAA data I had imported to tweak my dashboard. N
  14. The scintillator and optical grease arrived the other day, will start looking at the PCB in KiCAD so hopefully will make a start soon. Not quite sure which subject it would go under though? My progress... I am on holiday at the moment and I spent yesterday making some back-end changes. Rather than logging the date and time as one column, I have reduced them to two numbers - for date an integer in the format YYYYMMDD *, and for time the number of minutes past midnight. I did this as I would like to bring in additional data (the proposed Muon detector, GOES x-ray data from NOAA, may
