Did one last iteration of a portable vertical antenna loading coil to see how it would come out. Just went for the maximum amount of potential inductance with a reasonable form factor.
This one is about 3" in diameter & a foot long (75mm x 315mm). It has the same clamp on tripod & thumb screw contact ring for adjustment as the earlier version(s). Most of the winding core is hollow to save material & print time. Attached File Attached File Attached File Attached File Attached File It uses a bit over 62' of 16 awg tinned copper buss wire, wrapped 80 times on 255mm of the grooved form. There is a 3/8-24 thread extension on the top and a SO239 UHF connector on the bottom.

Meaning you will have to move the wiper less as you move up and down the band on the same band. Some of the best mobile screwdriver antennas have 5 or 6 inch diameter coils. |

Thanks for the insight. I'm thinking of pulling the screwdriver build apart & doing a gear drive for the M6 screw, moving a sliding contact rather than the coil. It would be shorter & more stable.

Decided to try the ADE rd pro optics planet had for $99.. short of getting another holosun 507k for $310 its the only cheaper option with a circle dot. Only one problem tho. The buttons stick out and during racking are super easy to accidentally push - leading to lots of fun cycling through options to get back. So i built a hood with a button recess - then i shortened it to just a button recess tray.. which seems to be a good option so far. |

Still kinda an expensive build, but it's pretty awesome. I'm having ejection issues, but I think it's due to the +125% spring. I bought a new spring I'm hoping isn't +125% to try, but haven't gotten around to punching the roll pin out and replacing the spring yet. |

I keep on saying to myself - just one more replacement part for my rebuild/upgrade effort on the printer.
I just re-printed in a different color my y-cable connector to match the weave of fiber sleeve. I understand that there is a set bonus factor if you have the right color combination. ;) This should be the last part I need to assemble, and the wrap up is verifying all of the cable runs are hooked correctly. Ok, maybe there might be a few parts to assemble; re-assemble during the tuning process. The cable clips I posted above for the printer worked; but would work better using ASA. I have the ASA, I just need to "build" a box to hold the printer in while I try my hand at ASA printing. |

I just printed my first print off a rebuilt Prusa MK III -> MK IV
It was just the simple Prusa key chain - dog tag found on the USB stick that came with the upgrade parts. When I was doing the final checkout and had the Calibration fail. At that point I remembered to put the built plate on the printer. Looks like newer firmware was a bit more picky and could tell that the thermal mass was off...or the issue could be I did install the hot end sock. The re-sell value on the broken MK III (No + or S) - was not that high, and I figured it would be "effective" to upgrade it to current due to age of the hardware. I guess my print farm is growing with 2 MK IV and one MK IIIS+. |

I disassembled the earlier screwdriver antenna build & used the components to assemble a motorized contact slider for the base loading coil. The new build uses gears to connect the 12v gearmotor & screw. The gears were done in OpenSCAD, imported into Fusion 360 as mesh bodies, then converted & edited.
The contact carrier has an embedded M6 nut that rides up and down on the screw. The 400mm allthread screw is constrained by 608 bearings at the top & bottom of the guide. A cap on the screw keeps it from passing through the top bearing. The guide was printed in two parts & joined with dowels. A tripod base will be attached, but is not in the pictures below. Attached File Attached File Attached File Attached File Attached File The contact is run from the top down & back up a bit. Mute or turn audio down to avoid listening to the motor whine.

Put some bypass caps across the motor connection to kill the noise.

whats the quickest, simplest, super useful, test print/starter? saw a layered glock build, seemed sensible, as you could replace parts when broken or mis printed?

I know there are "stronger" 37mm launchers out there but I won't be using them much and wanted the cool factor above bulletproof strength. Knowing the NT79 has some weaknesses, I built both these launchers using steel plates for reinforcements on the hinges and breach plate (SCS with files that were in the respective packs as noted below). All are sailing and can be searched by whatever I typed in "". I used the Lowe's pipe as recommended in the guide after realizing that the Home Depot pipe of the same diameter, won't work. All other parts were bought from Amazon using the specs on the guide. I did double up the springs on the ejector to help with sticky casings. I printed the NT-79 ("Are We Cool Yet? Presents: DaFizzlez's NT79 37mm Signaling Device") using the "NT79 Reciver with krrawn scs reinforcements" receiver and stock parts from the "NT79 Reinforced Retro Remix". The stock from the reto remix is a must! I found drilling out the holes for the support tube helped. I used 5 minute epoxy on everything. Overture black PLA+ on a MK3 using the settings on the guide. I painted everything with Rust-Oleum primer and paint. When I went to assemble everything was tight and I need to remove paint at certain locations. I wouldn't paint again next time, prior to assembling. I've shot five commercially purchased "cracklers" and it functioned perfectly with zero FTF or other issues. No cracks anywhere are visible. The "KRRAWNs MCRN Boarder remix" was printed as the pack comes with white Overture PLA+ on a MK3 using the settings on the guide. The MLOK covers are from Strike Industries. I learned from the previous build NOT to paint before assembling as the tolerances are tight and paint layers will cause issues. I used 5 minute epoxy on everything. This one was painted by hand using acrylic paint and I dyed/wet molded some leather I had on hand for the grip. I've shot two commercially purchased "cracklers" and it functioned perfectly with zero FTF or other issues. No cracks anywhere are visible. Last but not least, the 37mm rounds I got from exotic ammo in a sampler pack, sucked! Three had the payload pop in the barrel. The crackle rounds in reusable Aluminum hulls worked perfect. View Quote Cool to hear you're having success with it. I started an NT79 build but never finished it due to all the issues people were having with them failing, and then took the trigger out of it for a Hoffman build. |
