No. A larger core will allow for larger wire and less wire loss.Do I understand correctly that large cores will have large losses?
I was told that even the conversation itself is not legitimate. But I'm not going to stop, I will try to make the device as legal as possible, but I will.Good day. To put it mildly, the installed camera in your home will not be a problem from the legal point of view if it records what is happening near the house. Everything else described will have consequences from the point of view of criminal law and you can be prosecuted, namely: the manufacture of explosives, lasers, smoke grenades, dazzling means, etc.
Also, I will answer you simply, in the words "TNT", "explosives", "grenades" you can stop and consider it illegal. Here, even the very idea of using these means and making them for use in relation to a person already strikes many questions.
If you are stopped by the articles of the criminal code, then believe me, installing cameras is the most relatively legitimate of your ideas. All other conjectures when reading questions from you on this topic, many questions arose from the SBU officers, and this is their jurisdiction over the manufacture of bombs, explosives, etc.
