Tank with Coilgun Arduino

thingiverse

Hello. I'm finishing up the assembly of my tank with a Gauss gun, maybe someone will find it interesting. The video of the tank will be later, I'll add the video of the Gauss gun now. The elements of the Gauss and chassis were not printed on a 3D printer, only the body of the tank and the gun are available. For the rotation of the turret, I made a homemade bearing from 4.5mm airgun pellets. I need 10 pieces. A servo SG90 is used for the rotation, so the turret will rotate only 180 degrees, but it's enough for me. I used a ready-made converter because the homemade one overheated quickly and I didn't want to make a current limiter. The one I bought in stock isn't available, but similar ones are sold https://ru.aliexpress.com/af/45-%25252d-390-%25D0%2592.html?ltype=wholesale&d=y&origin=n&isViewCP=y&catId=0&initiative_id=SB_20170213221033&SearchText=45+-+390+%D0%92&blanktest=0&tc=af. The video of the Gauss gun test is here https://www.youtube.com/watch?v=5hh4ZZiEHcM&t=5s and the chassis test is here https://www.youtube.com/watch?v=1O_bhBq07Lk. I control the tank and gun with Arduino. For assembling the turret and body, M2 and M2x6 screws are needed. 8 pieces of each are required for the turret and 4 pieces for the body are required.

For the bearing, M3 screws and M3x12 are required. 2 pieces of each are needed.

The rear lights need to be printed, 2 pieces, one mirrored, from transparent plastic. In the turret: 2 laser modules are installed https://ru.aliexpress.com/item/10PCS-LOT-5V-Dot-Laser-Head-Diode-Semiconductor-Laser-Tube-6MM-650NM-5MW-OD-Copper/2045900689.html and 4 LEDs, 2 white 5mm and 2 red 3mm. In the tank body: 5730 white LEDs are installed in front of each light, 2 pieces in each, and 2 red 3mm LEDs are inserted into the rear light.
