Topic: DIY projects you plan to do or have done
I am currently working on two DIY projects:
1. An electrical short longboard for fast driving around the village :->
2. An awesome weapon: A coilgun
For number 2, I already have some more specifications on how I want to do this shit.
First of all, I'll use a 400v, 2700 µF capacitator. Already have it here, though it is not loaded. This thing is no fucking joke! Touch both ends and you will most probably die or get serious injuries. A friend of mine once touched a not fully disloaded cap, and he doesn't feel shit in his hand now. As if the nerv for pain in that hand was just like..burned away or something.
Second, as projectile, I will use 6mm steel BB's. Though they might not have the best magnetic specifications, they are easy to obtain and high in quantity.
I am not sure about the coil itself, I have wait until my dad gets his 3D printer finished. Then I can make a coil creation apparatus, cause yes, I am lazy. I have to calculate how big the wire must be and how much rings I have to put around the plastic (lol yeah) barrel. Once the coil is done, there is still the problem of...how do I sent the impulse right? If it powers to long, the magnetic field draws back the projectile a bit. If it powers to short, the projectile isn't accelerated to its full extent. Both unwanted scenarios.
I have a luger rifle scope for paintball here, it kinda works and will be for aiming this beast. The outerior will also be plasic housing. I'll print it from the 3D printer (can print big parths with that badass thing). Therefor, I'll need plans in a specific file format. It can be created with google sketch or blender, meh.
So now imagine I have the Coil and the whole shooting thing in place, how do I charge the cap? Not easy, I am not well informed about that (thanks for nothing, physics teachers!). If it should work though one day, you'll get an AWESOME vid of a greatly engineered CG. I hope that it will have high range and will be strong enough for ... let's say a quarter of a woodstump.
I'd never shoot this thing with electronics near me hence it will propbably create a strong magnetic field, and maybe even some EMP like shit. Though I'll dive deaper into that knowledgeable pleasure.
3. What kind of projects do you guys do in your spare time?
When in doubt, move north. God bless suomi.
