I agree 100%. I wonder why some people see a way for overunity in a setup that so many electronics amateurs played with, from the 70's, without having seen the least anomaly.
Actually the blocking oscillator goes back probably to the 20's or earlier and was accomplished with vacuum tubes. My first was built in the mid 50's using transistor CK722 when they first became available to hobbyists for less than a dollar. It was used to illuminate a four foot fluorescent tube held in the hand as we walked the streets as part of a halloween prank. Maybe this was the first actual lasersaber. It is always interesting and often humorous to watch persons completely unskilled in switchmode designs attempting to build these things. Sometimes they get lucky and even a blind dog occasionally finds a bone. A little knowledge is a dangerous thing. LOL I have always been an electronics amateur at heart. (one who loves what they do) and also an engineering professional that was paid $$$$ for a more rigorous skillset, but essentially doing what I love. A blocking oscillator can be a simple tool to act as a catalyst for some other process. In itself, and with traditional materials it will not yield OU. Most folks that play with these things never make accurate input / output power measurements and as a result believe they have discovered something new. They have not. In essence, a blocking oscillator turns a voltage source e.g. a 1.5 volt battery into a current source. As a current source it can illuminate strings of LED's far in excess of the battery terminal voltage (which to the uninitiated seems to be a miracle), but the power is always accounted for. Power in = Power out - losses. Lasersaber never does a careful accounting of power. His videos resemble a magician doing tricks, not an engineering assessment of the circuits merits, because he has a fundamental lack of knowledge regarding power magnetics design. Tektronix uses blocking oscillators which are rigorously and robustly designed as part of the HV generation circuits in some of their older oscilloscopes. I am willing to discuss the merit and downsideof Lasersabers latest circuit if anyone is interested. It does show some accidental novelty.
