Thanks to everyone. I had a few more questions but these were answered in each member’s reply.
I spoke to my buddy again and he said that he was electrocuted also. At the moment of the strike he was rolling his cursor ball on his chart plotter and the shock caused his arm and wrist to curl up...
Thanks, so would it be safe to say that if the radio is connected to say a 8-d battery alone with no path to earth ground it would be completely safe from a lightning strike. Can you think of any scenario where the radio could be damaged.
I was talking to a friend of mine that owns a commercial shrimp boat about lightning strikes on his vhf antennas. He said in his experience that wires only on the ground side of battery connections would be melted. I was wondering if someone could give and explanation of why this would be so. Is...

Maybe these guys can help with a solution. One of the techniques they employ is. simulated predator bird calls instead of ultrasonic.
I believe the plastic spike strips I saw were not so effective is because of the design. They were a long...
In the Gulf of Mexico oilfields the problem is seagulls and brown pelicans. As Andre said they become accustomed to anything that’s tried. The unmanned platforms have foghorns on them which are deafening if your near them but the birds act as if there not even there. Someone had the idea of...
I have a psc motor on bench that doesn’t have capacitor attached. I instead have volt meter attached to those wires that normally attach to cap. Since there is no capacitor I can start rotation in either direction. If I start rotation in one direction I measure 120 vac but as I load motor with...
I was able to find this video that demonstrates the effect a static magnetic field has on transformer. I was hoping to find some information on unidirectional square wave pulsed coils but no such luck. If there is any disagreement on content of video I would interested to hear them.
Assuming there are no tricks I was wondering if anyone had and explanation for what is happening. The only information is that transformer is fed with 50 percent square wave and amp meter reading.

I read the comment section and the third reply seemed reasonable but would like to know...
In post #6 you stated it might struggle to pump up to 2 meters even with small diameter tubing. I could be wrong but a smaller diameter tubing would make it more difficult to pump than a larger diameter tubing because of friction losses. I don’t think the diameter effects the static head pressure.
@Externet, I was thinking the same thing because I had one of those type at my home. I’m not a plant expert but rainwater is considered to be better for plants than city or well water because of its purity. But anyway if you can afford to have a summer home you probably won’t mind the extra...
The brand name Rule pump is the most common pump in the area I live. They are centrifugal pumps and mostly used in small sport and commercial fishing vessels as submersible bilge pumps. The whale pump looks to be a diaphragm pump. On the 120’ vessel I’m on we have 1 hp 3 phase centrifugal pumps...
On the way out to a offshore oil platform the other captain let me borrow his sunglasses. When I put them on I could see these blue lines in all wheelhouse windows. Was wondering what causes this effect.
