Megavolt attached a second module to his coilgun - the resulting device with a maximum projectile velocity of 151 m/s was added to the Accelerator Table. As you can see, the ambitious task of exceeding the speed of sound is still far from being solved, but the case is progressing. Interestingly, the empirical parameter Kx increased during the transition from a single-module design to a two-module one, while the G-factor, on the contrary, decreased. My hypothesis (which appeared after discussions with the author of the design) is that this is caused by the incipient influence of the skin effect in the solid ferromagnet of the accelerated body. If this is the case, then with a further increase in speed, the problems will build up... Let's see what ... Read more » |

A wonderful device added to the Accelerator Table - a multistage (40 coils! ) coilgun MR9. Its peculiarity, in addition to the recuperative scheme, consists precisely in the gigantic number of accelerating steps - a record among all the gauss-guns of the Table. And not only that - to be honest, I have never seen an accelerator with such a number of windings in all the time of my passion for Gauss-building, i.e. for almost 20 years! This design also made it possible to obtain a huge acceleration length of more than 40 cm, which, combined with the relatively low energy spent on the shot (approx. 126 J) gave an absolutely phenomenal efficiency - more than 32 % !! This in itself allows us to call ... Read more » |

Recently, I decided to fix some links in the Accelerator Table. In addition, there was a desire to make the information in the table more specific, namely, to take into account such a value as the length of projectiles when calculating the G-factor. In the course of the work that began, errors in previously performed calculations were also revealed, and as a result, I had to conduct a complete revision of my recent articles with corrections to the formulas in them and changes to the numerical values ...

New video dedicated to the "brains" of electromagnetic accelertors added to my Youtube channel, interrupting its prolonged lull (no english-spoken movies have been there for 8 months, my fault....). Good luck to everyone in 2024 again! |

Merry Christmas and Happy New Year to everyone! I also wish You health and wealth, and new technical achievements in 2024! |

Another useful thing from Aliexpress - a miniature voltmeter. Having +5 V to the red wire regarding to the black one (which may be conviniently taken from any USB-charger with the corresponding connector) it can measure up to 3000 V (!) on the white lead - very handy for gauss-builders....

As part of equipping my home laboratory, I bought myself such a miniature power source from Aliexpress. 5V x 30 A are squeezed into dimensions of 185x100x78 mm and weight less than 700 grams! The control potentiometers also have a push action, so that each digit of current and voltage can be adjusted separately. There is nothing superfluous in the kit - a power cord and two banana-crocodile cables are what you need, I love minimalism. Such an animal costs less than 30$. I received it today, tested (nothing heats up even at maximum power, limitations work, accuracy is normal) and decided to order a couple more.
