Whenever we see a coil gun project on the Internet, it seems to involve a bank of huge capacitors. [miroslavus] took a different approach with his gun–he wanted his project to be built without those monster caps.
It’s powered by quadcopter LiPo batteries, 2x 1400 MaH drone batteries wired up in series and triggering 21SWG copper coils that [miroslavus] created with the help of a custom 3D-printed winding rig he designed. The rigs have ridges to help you lay the coils down neatly, and they also have mounts for photodiodes, ensuring the gun knows when it’s loaded.
When triggered, the Arduino Nano activates a pair of IRF3205 MOSFETS with logic signals stepped up to 20V, shooting lengths of 7mm or 8mm steel rod
3D printing has been slowly finding its home in industries that require lots of specialization. In medicine, for example, 3D printing—also called additive manufacturing—has been used to create artificial organs that actually bleed when they’re cut (implanting these into human patients is still a ways off). The tech could be used to lower costs in construction, too. But as additive manufacturing is used in more fields, hackers will naturally be interested in locating weaknesses. Last year, researchers sabotaged the printing of a drone propeller, which caused it to malfunction and crash two minutes after takeoff
The Japanese Aerospace Exploration Agency has released the first set of images and videos taken by its debut zero-gravity camera drone or “Int-Ball,” the cute orb of a drone, will optimize communication between crew in space and on Earth.
Huddersfield based online retailer Drones Direct claim to have modified a popular automated aerial vehicle that allow dog walkers to set a GPS route via a smartphone app which the drone will follow
