NYC Nerf Ops 5: Foamcoming (Saturday April 29th)

01 April 2017 - 06:47 PM

The NYC Nerf Ops FB group is stoked to announce our next superstock war.

 

Date: 4/29/2017, 10:00 AM - 5:00 PM

Location: 40.782278, -73.963951 (Manhattan, Central Park)

Blaster ruleset: Superstock (~150fps max), melee weapons permitted

Game rotation: 3-15, Turf War, Sticks and Stones, Harambe Escort, Flag Push

 

Up-to-date info and non-NIC attendee list are available on the Facebook group page.

No rain date - the war continues in all weather. 
The battlefield is a five-minute walk from the Metropolitan Museum of Art.

 

The venue is a small, open field surrounded by trees. There's a lot more cover than a standard public park, enough to make Rival blasters competitive.

MANDATORY EQUIPMENT:
- Primary blaster. See Weapon Info below.
- At least 200 rounds of STOCK ammo. Homemade and modified ammo is banned.
- Eye protection. All players must have safety goggles. Glasses, toy goggles, and masks are not sufficient.

RECOMMENDED EQUIPMENT:
- Water. There are no water fountains or 'street meat' stands nearby.
- A pistol, melee weapon, shotgun, or bow for Sticks and Stones
- 500+ rounds of ammo
- Garbage bags, for cleanup

WEAPON INFO:
- Blasters must be colorful. 
- We highly recommend using modified flywheel blasters.
- Melee weapons must be fully padded, including the shaft and pommel.
- See below for info about the "Sticks and Stones" special weapon restrictions.

SCHEDULE AND GAME RULES:
The first round begins when four players arrive. We generally alternate elimination with objective games. After each round, we will have 10 minutes of downtime, or 20 if we need to sweep.

Game rules:

 

Turf War Elimination:
- Teams may have any number of players. Each team decides on a color.
- Each team has ten shared lives. When you're hit, yell your team color and your team's new life total.
- 15-second respawns
- When your team runs out of lives, all team members are eliminated.

Sticks and Stones Elimination:
- 5-15 ruleset
- You may only use pistols, melee weapons, shotguns, and bows.
- Nerf Clip System blasters and compatible blasters are not pistols.
- The Nerf Apollo is not a pistol.
- Shotguns must fire at least two darts with every trigger pull.

Harambe Escort:
- Objective: Escort Harambe to freedom, or gun him down.
- Harambe the gorilla has two lives and is unarmed. Other players have infinite lives and may use any blaster.
- While Harambe is standing still and beating his chest, he is invincible.
- Harambe is escorted by four memelords. The remaining players are zookeepers.
- Harambe begins at Point A. If he touches Point B, the memelords win. If he dies, the zookeepers win.
- Memelords respawn in 15 seconds. Zookeepers respawn in 30 seconds.

Flag Push:
- Objective: Attackers attempt to carry the flag from Point A to Point B. Defenders must hold them off for ten minutes.
- Attackers begin at Point A. Defenders begin at point B. All players have infinite lives.
- Attackers respawn by touching Point A. Defenders respawn by counting to 15 WHILE touching Point B.
- Before the timer begins, defenders have 30 seconds to set up and may position themselves anywhere on the battlefield.
- Defenders may not touch the flag, except to stand it up.
- To carry the flag, an attacker must hold it in one hand, clearly visible. Nothing else may be carried in that hand.
- When an attacker is hit, he or she must immediately drop the flag.


3D Printable Rapidstrike Mod Parts

03 January 2017 - 04:54 PM

Hey all, I'd like to share some parts I designed while modding my Rapidstrike. All of these are released Creative Commons 4.0 Noncommercial Attribution Share-Alike.

 

Editable models and installation instructions are hosted on Thingiverse. I've attached STL files to this post for convenience, but I recommend visiting Thingiverse as well.

 

Pusher Motor Cover and Nameplate

Attached File  2016-12-29 15.35.05 scaled.jpg   94.28KB   17 downloads

 

If you upgraded your pusher to use a 180 motor, this cover plate prevents shorts while still allowing ventilation. It also neatly covers the Rapidstrike logo so you can pimp your blaster.

Replace your Rapidstrike's sling loop and rear sight with TWO OLED screens. If your sick gaming rig needs two monitors, so does your sick blasting rig.

If you removed your Rapidstrike's stock, you now have a gaping hole. Install this butt plate and now you don't. I included two versions - one has a cutout for a battery connector or a USB port, the other is solid.

Thanks for viewing, and good luck with your Rapidstrike modding.


JSPB C5 Sight is Badass

03 January 2017 - 01:20 PM

I've never seen anyone post about the awesome sight that 3DBBQ designed for the C5 Launcher. It snaps onto N-Strike rails and looks cool as hell.

 

You can buy the STL file from the JSPB site for two bucks and print it on your own machine.

Preview: Rapidstrike Electronic Fire System

08 December 2016 - 01:11 AM

I've been working on an electronic Rapidstrike driver board, and I thought I'd show youse guyses as I build it up.

 

Attached File  2016-12-14 02.31.58 scaled.jpg   91.04KB   18 downloads

 

Working title: The Hot Beef Injection.

 

Attached File  HBI Driver 0-1 Screencap.png   44.06KB   15 downloads

 

This first PCB is the motor driver. It replaces the Rapidstrike's front tactical rail and enables more sophisticated control than bare microswitches. Each driver is rated to 40A; a heatsink and temperature-controlled fan keep heat under control. This includes:

  • Full PWM - the system can ramp up the flywheels slowly, and keep them running at reduced "idling" speed
  • Dynamic braking - Prevents pusher overshoot, and lets me quickly halt the flywheels for "stealth mode"
  • Sensorless closed-loop control - I can tune the flywheel speeds to maximize energy transfer
  • Current sense - For fun. Also detects shorts and breaks for self-tests and safety.

 

Attached File  HBI Motherboard 0-1 Screencap.png   226.88KB   15 downloads

 

This PCB holds the Teensy microcontroller and has a 5V buck converter for efficient power. This slots into the empty space where the retractable stock used to be. The large connector on the end links this to the motor driver. The other sockets are for I/O:

  • Top left: Trigger and rev button inputs
  • Bottom left: Two OLED displays connected with I2C
  • Top and bottom right: RFID board in mag well to detect magazine sizes
  • TBD: Stock pusher endstop switch and mag detect switch

I used a goofy layout, fat traces, and too many vias are because I'm etching these prototypes by hand. The copper clad should arrive soon, so I'll update the post when I etch them up.

 

Thanks for reading! This is an exciting project, and I hope to finish it by the 17th to bring to CPNO.


The Mackazine

30 July 2016 - 03:46 PM

Hoppers are simple, powerful, and reliable, but ball valves take forever to reload. Instead of feeding darts one by one like an asshole, replace the entire hopper like a magazine - a Mackazine.
 
Attached File  2016-07-15 14.18.28 scaled.jpg   109.14KB   33 downloads
 
This uses a 3D-printed part, which you should print at crappy resolution with 15% infill. If you're not a member of the glorious 3D printer master race, you could mold one out of epoxy putty or ShapeLock or even carve it out of wood.
 
This project is an improved version of Aeromech's Quick-Change Hopper Clip.
 
Materials:
  • A hopper's worth of PVC pipe
  • An endcap or plug
  • Heavy-duty tape like Gorilla Tape
  • One tape measure, to be sacrificed for the greater good
  • One 3D printed / handmade retainer (STL attached)
  • Two spare self-tapping screws (about 1/8")
Attached File  2016-07-26 00.49.13 scaled.jpg   56.61KB   30 downloads
 
STEP 1: Glue your endcap or plug into the hopper. Blasphemy.

STEP 2: Cut a 5 3/4" segment of tape measure. Drill 1/8" holes 1/4" and 1/2" from one end. These measurements are easier than usual because you're cutting a tape measure.
 
STEP 3: Cut a strip of tape long enough to cover the tape measure. Fold it over the tape measure. Use heavy-duty tape - the glue on electrical or duct tape can soften in heat and expose the razor-sharp metal.
 
STEP 4: Use two screws to fasten the retainer to the strip, right through the tape.

STEP 5: Tape the retainer assembly to the hopper. Your Mackazine is done!

STEP 6: Optional: Sand the edge off your blaster's wye to make reloading easier.
 
Attached File  2016-07-26 14.12.04 scaled.jpg   68.06KB   33 downloads
 
To fill a Mackazine, just shove darts into the pipe, heavy side up. You don't even need to hold the retainer open.
 
Attached File  Inserting scaled.png   1.76MB   23 downloads
 
To load a Mackazine, align the retainer with the wye and swing the mag into place. The tape measure will give way with an audible snap and release the darts.
 
Attached File  2016-06-25 18.11.57 scaled.jpg   104.04KB   29 downloads
 
You can carry them in a magazine pouch - one AR15 pouch will hold two. The pictured rig is a Voodoo Tactical Six-Mag Drop-Leg Shingle purchased from Amazon. Note that one magazine pouch is deliberately not loaded with Mackazines - mags in that pouch could jab my lower body if I jumped too aggressively. Gotta be safe!
 
TACTICOOL CONSIDERATIONS: The main advantage that Mackazines hold over a dart-by-dart system (ball valve, Hole Door, breech) is that the darts don't need to be oriented as they're inserted. You don't need to pull a handful of darts from a dump bag and turn them around as you insert them, which improves situational awareness while reloading. 
 
The main downside is the weight of the Mackazines. The pictured 10x10 loadout didn't affect my agility, but it was heavy and fatiguing over time. For extended wars like Apoc, I plan to carry just four extra Mackazines and retreat to reload if necessary.
