When the steel ball is pulled towards the magnet it creates an impulse of energy at the speed of sound. This energy carries through to the other side and expels the weakest link the magnetic chain at a high speed. Subscribe for more Scientific Tuesdays. New Episode every week!

Completely Portable single stage, 100 joule, bolt action, 6 round mag soon to be dual stage, 200 joule I've had a few ask how I built this gun so rather than answer everyone's questions individually I'll just answer it here. I started with a 12 volt SLA (sealed lead acid) battery that I found online somewhere. That powers a power inverter that you would normally use in a car to get 120 volts ac. That powers a voltage multiplier ( google it to find out what that is if you don't know that's how I found out). And that puts out the 385 to 400 volts to charge the caps. The capacitor bank is made of 3 electrolytic Caps that have a 450 v. capacity rating and I believe are 470uF each. The box in between the barrel and PVC pipe are 2 solid state relays wired in parallel to fire the coil. There is another solid state relay that turns the charging on and off. the Coil is made from 2 strands of 22awg magnet wire( it was what i had next time I think I'll use 1 strand of 18awg). From what I've found so far the size of the coil depends on the size of the bullet and cap bank. Mine is a little bit longer than the bullet and about 1" in diameter. I don't think mine is quiet right but I'm still working on it. There is also 4 hi cap diodes wire anti-parallel to the coil. This protects the caps and charger from the reverse voltage created when power is removed from the coil. So the Gun is basically controlled by 4 switches. The red switch is the main power and the blue switch turns on the charger. The safety switch allows the gun to be fired and the trigger turns on the relays that power the coil while at the same time turn off the charger. The frame is something that i just through together in a day to make sure the gun will actually work. The final version won't even look the same. I want to build this out of plastic. I also am looking for ways to make the charger smaller. So for the future plans: 1. adding a second stage. this might take a while. I need to use a PIC and don't have much experience with them. 2. semi-automatic fire. This will be done with a solenoid that knocks the bullet in to the first coil. 3. select fire. I want to be able to choose between one shot using 2 coils in secession or 2 shot burst using the 2 cap banks to fire the first coil twice. Or using the 2 banks as one big one to power a second coil gun. Kinda like a grenade launcher but instead of a grenade it will fire a bullet that has been hollowed out to fit a flash cap that can be charged to about 250 volts. I also want to swap out the solid state relays for SCR's because they will be a lot smaller. There are other things but I'm going to keep them a secret until I'm sure there going to work the way I want. Any way hope this helps, I'll put up more video as I get more stuff working.

After 2 long years of on-and-off work my coilgun project is finally completed. For anyone who doesn't know what a coilgun is, it's a gun that fires a projectile with magnetic force instead of gunpowder. The projectile from this gun won't kill a person, but the electrical energy stored in the capacitors is 78 times the lethal amount for human beings so this is no toy. Some technical data: - Action: single stage, bolt - Weight: 7.75lbs or 3.52kg - Power supply: 12V NiMH battery (needs recharge after ~15 shots) - Charging: 40 watt regulated ZVS flyback driver (charge time ~30s) - Capacitor bank: 4x 3900uF 400VDC - Stored electrical energy: ~1.25kJ - Switch: SCR - Efficiency: unknown, probably 1-3% - Body: lightweight ABS plastic pipe and sheets Pictures: ***********/watch?v=ovSVYK7zhpQ Discuss: *******4hv****/e107_plugins/forum/forum_viewtopic.php?96610 ***Answers to commonly asked questions*** Q: Will it kill a human? A: The only ways it will kill is if someone were to touch the capacitors or high voltage charging circuit, which could easily cause electrocution. I suppose if you fired it straight into your stomach or face from point-blank range and refrained from seeking medical attention afterward, you could die that way as well. The muzzle energy of the coilgun is not comparable to regular firearms. Q: You should shoot it into some meat! A: That's a waste of a potential sandwich Q: Will you sell it? A: Nope, sorry! Q: Will you post plans? A: And deprive you of the fun of building your own? Of course not! But I'm willing to point you in the right direction. It's not that hard- I started this project with zero experience with electronics. It takes more patience than anything else. Q: What are the songs in this video? A: In order: Kick It, Rally, and Behemoths from Mechwarrior 4, Invaders by Excision and Datsik, Still Alive by Jonathan Coulton and GlaDOS Q: What is the projectile speed/energy? A: I don't know yet. I'll post what it is once I have the equipment to measure it (speed trap, scale). Q: Will a smaller projectile result in better efficiency? A: No, a smaller projectile won't be able to absorb as much magnetic flux as a larger projectile, due to a phenomenon known as magnetic saturation (Wikipedia it!) Q: Will multiple coil stages improve power/efficiency? A: Yes! I only have one stage on this design for the sake of simplicity. Q: Will rifling in the barrel improve accuracy? A: No- not at these projectile speeds. A projectile has to be moving at a certain speed before rifling is effective. Also, rifling depends on the bullet expanding within the barrel, which doesn't happen with a magnetically propelled projectile. Q: How do you claim 1.25kJ of energy? A: Some websites which feature my gun state that I am delivering as much energy to target as a .45ACP. They are incorrect, either because they didn't read my description or maybe they just didn't fully understand it. 1.25kJ is the ELECTRICAL energy stored in the capacitors, according to the equation E = 0.5*C*V^2. For this gun, C=15600uF and V=400V, thus E = 1248J. One of the main drawbacks for coilguns is EFFICIENCY, which, for single-stage hobbyist designs (like mine) is limited to about 3%. So if we assume a 3% efficiency (as stated in the video), the kinetic energy (delivered to target by projectile) is in the area of 37J, which is much more than a bb gun but much less than a real gun. I don't have the equipment to measure the exact kinetic energy, but as soon as I do I will report it. Thanks! Q: You misspelled necessity! You suck! A: I'm SO sorry. How can I possibly make up for for all the pain and distress I've brought into your life?

This video shows all the rare SHOOTING weapons you can collect throughout the wastelands in fallout 3. All Rare melee weapons will be showcased in the next video. RARE WEAPONS NOT INCLUDED IN VIDEO- Firelance- The "random event" has not happened for me yet :( Protectron's Gaze- Recieved for giving the mechanist in canterberry commons the antagonizer's armor in the Superhuman Gambit. I did not include Colonel Autumn's 10mm pistol because I don't have it and its VERY similar to the regular 10mm pistol... boring. If you have any questions or requests, just post them in the comments... Thank you -7hrive Gamertag- iPod Touch Me

Love signal is a healing audio and visual meditation with music, sacred geometry and Solfeggio frequency 528 Hz, the miraculous frequency for transformation and DNA repair. There is a special sound and color of love according to Dr. Horowitz, a Harvard-trained award-winning investigator. Broadcasting the right frequency can help open your heart, prompt peace, and hasten healing. "We now know the love signal, 528 Hertz, is among the six core creative frequencies of the universe because math doesn't lie, the geometry of physical reality universally reflects this music; these findings have been independently derived, peer reviewed, and empirically validated," Dr. Horowitz says. Music & video by Jandy the Decibel Jezebel Poem by Katie Pye For a deeper meditation experience; use stereo headphones to stimulate Theta brainwaves If this video is not playing is stereo add &fmt=18 to the end of the url and press Enter. The Solfeggio Scale and note names; 1. UT...396 Hz (Center Pillar of the Tree) 2. RE...417 Hz (Left Pillar of the Tree) 3. MI...528 Hz (Right Pillar of the Tree) 4. FA...639 Hz (Center Pillar of the Tree) 5. SOL..741 Hz (Left Pillar of the Tree) 6. LA...852 Hz (Right Pillar of the Tree) The first note, "UT quent laxis," is defined in Webster's Dictionary as "the Gamut of dramatic emotion from grief to joy," and "the whole series of recognized musical notes." It has a frequency of 396 cycles per second, and is also associated with a "magnetic field strength equal to 105 power gauss," or 100,000. The second tone, "RE" - short for "resonare fibris" or resonance - also correlates mathematically to 144,000. The third note, frequency 528, relates to the note MI on the scale and derives from the phrase "MI-ra gestorum" in Latin meaning "miracle." Stunningly, this is the exact frequency used by genetic biochemists to repair broken DNA - the genetic blueprint upon which life is based! MI - 528 Hz - relates to crown chakra. Dr Puleo suggests an association with DNA integrity. The regular "C" that we all know of in this culture (which is from the diatonic scale of do, re, mi, fa, so, la, ti, do) is not the 528 Hz frequency "C. A regular "C" vibrates at a frequency of 523.3 Hz. The "C" of 528 Hz used for DNA repair is part of an ancient scale called the Solfeggio Scale. UT - 396 Hz -associated with releasing emotional patterns after: see RE-417Hz below. RE - 417 Hz -associated with breaking up crystallized emotional patterns MI - 528 Hz - relates to crown chakra; Dr. Puleo suggests an association with "DNA integrity" Transformation and Miracles FA - 639 Hz - associated with whole brain quadrant interconnectedness. Connecting Relationships SOL - 741 Hz - associated with intuitive states, non linear knowing. Awakening Intuition LA - 852 Hz - associated with a pure love frequency: unconditional love and returning to Spiritual Order
