I got my thunderboard kit from the kickstarter. I had so scour the site to find the wiring diagram for assembly. I figured out (with a friends help) the module to select in order to program the arduino. Then, I was confused by the fact that the system indicated that the noise level was too high. After looking at the code,I found some of the lines addressing disturbances. DO you have a tutorial that will tell me what to do with this. (mind you, I haven't created the post, but I do have the detector board as physically separated as I can (whist still being wired up.)
I'm primarily concerned with my system generating false positives (and I know they MUST be false) and dialing them in.
Additionally, do you have any way of showing on the display the time since the last successful "PING" of the server.

You have a noisy environment. Do you have one of our Lightning Simulators? This is a tough situation to debug without using one of these tools. This is why we had to build one of these. You can get on DIgiKey, but they are $250 up there. We build a much lower cost one. shop.switchdoc.com/products/the-thunder-board-i2c-lightning-simulatorYou could display that information, but it would take some programming. The software knows if the PubNub succeeded, so you could note the time there and then display it. There are good models in the code on how to do the display. Best, BP |

I think the biggest source of noise is a FM transmitter that is about 2 miles away. It's pervasive. Gets into everything. (I'm the local expert with regards to EMC for the company I work for.) I've shielded many thing around the house against such interference. I am able to listen to AM radio (for what little there is around here (Ephrata, PA)) I mostly listen to DX. Anyway, I feel like I should have anticipated this, but at the same time, with a decent AM radio, I don't get interference. I tried to use a crystal radio (for my Goddaughter), for an AM radio ... I could only get the FM station on the hill. I will
1) try to make some adjustments (RF shielding from that direction.)
2) move the detector to my Parents house (about 6-7 miles away)
3) will order the Simulator.
I suspect the order for the simulator will be placed next week.
Thanks for the info. Will keep you up to date.

Thanks for the information back. These problems can be very hard to track down. As an EMC guy like you can understand!
Best,
BP

When I had completed my "tower" case for the detector, I found that it was no longer detecting false strikes. I still get some noise indications, but nothing in the way of false detection. Of course, we haven't had any storms in the area, and I haven't tried to simulate the EMP/EM noise from a "strike". (Been busy lateley.) It also seems to me that it is important to keep the receiver horizontal in order to reject the noise from the local FM station. I will (try to) keep posting updates.

Makes sense. Sounds like the computer was the biggest noise source.
Thank you for posting this. These kind of experimental result postings helps everybody, including me!
