A new excellent sample has been added to the Accelerator Table - Tokamake's TK20-mini. Thanks to the optimization of the coil parameters, the author managed to achieve an unprecedented 127 m/s in the pistol format! In terms of the G form factor, the design ranks 3rd in the Table, and the first in terms of Kx (more than a hundred!). Congratulations on the record!

The third part of the series dedicated to Gauss guns is finished! It describes the first step to their optimization - the converterless coilguns. Nice watching!

I finished the second series of videos about Gauss guns. It discusses the advantages of this type of electromagnetic accelerators, both real and mythical.

I posted a new video about the ZVS converter, while it's about modeling and researching the suitability of ZDS for capacitor charging. The second part will be experimental. This mini-series is planned to be the last on the subject of voltage converters, the following videos will be devoted directly to Gauss guns.

A new series of videos started about Gauss guns. The first one summarizes the principles of operation of such accelerators and their main disadvantage - high cost at low projectile velocity. A more complete description of these and other issues can be found in the "Theoretical articles" section.

I finished the development and posted a video in my VK-community and Youtube-channel about creating another converter for charging high-voltage caps, this time powered by just one lithium battery. Its feature (which has led to both advantages and disadvantages) is the use of cheap and easy-available components, in particular, a PWM controller and a ready-made transformer from AliExpress.

Work on the project was difficult and took a long time - the first version of the converter, despite a l ... Read more »

A compact boost converter for charging high-voltage caps has been assembled and tested. It is based on the LM2577 (or LM2585) microcircuit, which I mastered well while working on the stun gun. The presence in this IC of a built-in power switch, generator, error amplifier with a reference source - that is, all the elements of the PWM controller - in addition to a wide range of supply voltages and temperature protection, made it possible to create a simple and reliable design. It is easily repeatable even to untrained people without the HV skills. In addition, the circuit uses a ready-made cheap transformer from AliExpress, which eliminates the need to manufacture an inductive element. M ... Read more »

I have completed a large study of the properties of various transformers in saturation mode. The video turned out to be very long (almost an hour), but I didn't want to split it into parts, so I added timecodes. The methodological part was slightly out of focus, for which I apologize in advance. The topic is quite specific, as they say, "not for everyone," but for the curious, enjoy watching!

As promised, I posted the latest (at least for the near future) video on the "shoker" theme, which touches on interesting aspects of working with HV transformer. It should be interesting for "advanced" shocker-builders, laser shooters and railgunners. Enjoy watching!

Two parts of the video added to my channel, describing construction of electroshok device of orginal scheme (only in Russian, use subtitles if desired). Nice viewing!
