Fun with Gauss

at 8:04 am. Filed under Crazy Hacks, DIY Hacks, Electronic Hacks

What is Gauss? According to whatis.com is: “The gauss (symbolized G) is the centimeter-gram-second (cgs) unit of magnetic flux density. A flux density of 1 G represents one maxwell per centimeter squared (1 Mx ­ cm-2). The gauss was named for the German scientist Karl Friedrich Gauss.” How can this be fun? Watch the videos below and you will soon see! Check out FastMHz for more project details.

“A Gauss Gun is a weapon that fires projectiles using electricity instead of combusion or air pressure. The basic concept is to dump a ton of energy into a coil as fast as possible, generating a strong magnetic field to “suck” the projectile through the coil. The trick is to design your coil properly so that the coil is off by time the projectile leaves it, or you end up with a giant, non exciting solenoid. The cheapest way for the hobbiest is to use large capacitors and a large circuit breaker for a switch. If you have some money, Silicon Controlled Rectifiers (SCRs) are the way to go, allowing less energy to be wasted during switching.”

    These Gauss guns look like fun! FastMHz, the build looks great.

    Here are some other interesting non electric Gauss guns.

    Also check out the handheld Gauss gun:

    Awesome! Thanks for the compliments and links!

    where would one find capacitors that big? i want some!!

  4. FastMHz Says:

    I got them on eBay…just search for “High voltage capacitor” and you’ll see plenty. I paid about $80 for my entire set.

    Awesome – now I am thinking electric vehicle drag racing with that sort of acceleration…

    What sort of voltage would it take to send a car and driver down a 1/4mile strip in say 5 seconds?

    Would they live 🙂

    is there any “blueprints” that you would be able to send me, or a link?
    if you have some for a smallscale, like yours, email to me at threedmaster@yahoo.com

    Dude, do you work for HAARP or something? If you dont maybe you should! That was pretty cool stuff there! Like a mini rail gun, right? Nice demonstration.
