If you are looking for a guide, check the [Instructable]. =D More pics are available on [Phil Source – Flickr]! SO, why did I do it? Well here is a bit of a backstory: My university started playing HvZ in the spring semester of 2010. When I first read about the game on its facebook page I was skeptical that there would be many people who would be willing to let their nerd out like myself. So I chose to use a basic NERF Longshot (Which I heavily modified) and got myself a sidearm, however during the first mission about 200 students arrived; all decked out in tactical gear and a plethora of modified NERF weapons. The next day I took all my tactical gear out of my closet from my airsoft days and went out to have the most fun on campus that I ever had. However I quickly learned that NERF Blasters will not shoot father than 20-30′ stock (The box always lies). This is obviously due to the fact that they are toys, you don’t want a child shooting anothers eye out now do ya’? After heavily modifying the inside of the NERF Longshot another issue arose, the aerodynamics of the darts caused them to spiral out of the barrel at higher velocities rendering them useless. This second realization led a small group of the crazy players (Mostly engineering students) to experiment with our own custom darts made from foam backer rod. But even after making the best darts we could, we still needed more firepower. I opted to go for a longer range approach, with a semi-auto firing mode….. It was knicknamed the OP-1 (Over Powered…. first version). With a range of 200′ angled, and a semi-auto firing rate nearing 5 rounds per second, meant “Zombies” wouldn’t be able to get close enough to my squad to charge. My role during our missions was not to pick people off at insane distances as most players will just pretend they didn’t get hit or walk off just to return immediately; instead it was to keep them at bay. So even when they thought they were safe and could taunt us, a dart to the chest ended their dancing and reminded the rest that they should hide behind something. This page is more of a showcase and a small explanation on how it functions. This is not a project that can be easily made with a hand drill and a dremel, if this is something that appeals to you please check the Instructable for more step by step documentation and cad drawings (In PDF form) for the main bolt mechanism. On to the pictures!!! External Photos: Here is the original NERF Longshot: After a LOT of modification, here is the...
Laser cutting filtration cabinet: Preface, I recently moved into an apartment with my Fiance and unfortunately had to leave my big machines at my families house (Tormach 1100, CNC masters lathe, Smithy 3 axis mill). I was able to bring my MaxNC desktop mill and once I finished an enclosure to make it apartment friendly i set out to build a 3D printer capable of making resin cast ready parts. I decided that a laser cutter would come in handy to build my inkjet style 3D printer, so i purchased a full spectrum 5th generation laser. Between my MaxNC 4 axis mill, laser cutter, and Makerbot I should be able to make any of my smaller projects in-apartment. Project Background: Now that I had a laser cutter on the way I had to provide a stand, air filtration system, water cooling for the laser tube, and an air assist system. I decided to combine all of this together in as tight a space as I could, while also making sure it was apartment safe and visually pleasing.I know you all look at the pictures first so here is an image of the finished product. And the internals: DISCLAIMER: I lack carpentry skills, I am at home working in a machine shop but I’ve never been good at working with wood; Do not expect professional carpentry. I wanted to share this project in case there is someone else out there who is in a similar situation. The following project log will be broken down into these parts: 1. Bill of Materials 2. Tools required 3. Filtration Unit Construction 4. Blower installation and connection 5. Water cooling installation and support structure 6. Air assist connection And here is a pic of my milling enclosure: I would advise anyone attempting this build to locate the nearest friend who owns a table saw and a jig saw as it will make your life drastically easier. Feel free to substitute the MDF for plywood if you have it available, the only reason I went with the MDF was because I had it on hand from a previous project. My main limitation with some of my material choices was the space available to work, most of the work had to be done on my coffee table in a small apartment. Bill of materials: 1/2″ MDF Sheet (2′ x 4′) x 2 –> $10ea at Home depot [SKU# 279388] 1″ SQ wood segments x 4 –> ~$2 ea at Home depot [Used to build exterior stair railings] Chicken wire 25′ –> $13 at Lowes [Item# 92679] Fiberglass screen 25′ –> $6 at Lowes [Item# 15542] 4″ to 6″ Duct fitting –>$8 at Lowes [Item# 127823] 4″ 90 Deg Elbow x 2 –> $4.50 at Lowes...
I’ll go ahead and say it right now, I look terrible in this video. I’ve been working on some 3D printed furniture over here at LM, you can check the video out at the page below:
I concatenated all of my videos and featured articles for LM here at my site. You can find them at the link on the nav bar above!Learn More
Last night I posted a project on Hackaday.io in order to enter it into the Hackaday prize. Any support is appreciated, i’m very excited to finally get this project completed!
If anyone reading this feels like helping out please feel free to donate, anything will help us to achieve our goal.
In other news I’ve been filming many more videos at Local Motors in order to document the build process of a open source vehicle DAQ/Controller.
Alright so I’m “Settled” a bit in AZ, but my new apartment is still in shambles. Local Motors is by far the best place I have ever worked. I can’t believe I get paid to have fun all day. I filmed my first “How To” video on Thursday, I haven’t done much actual engineering yet as we are neck deep in preparations for the Local Motors Summit 2014. However I think in order to effectively engineer improvements for the current LM product lines I need to know how to put them together with my eyes shut anyway. Check out the video!
So I have been delving into a multitude of projects to finish before my move to Arizona. I’ll be starting full time at BioLite Stove in the city for 4 weeks, and then i’ll be moving out to Tempe Arizona to work for Local Motors as a Vehicle Design and development engineer. Very exciting, but very busy times over on this end.
I plan on doing a full write up for this once It’s complete, but that might have to wait until next month once I’m out in Free America.
With several of my friends coming home from military deployment I gladly joined them for some overdo range time. One of my friends had injured his hand in the past but the tendons never healed properly and he can’t grasp small objects very easily. When shooting his Ruger 10/22 Takedown he complained that he couldn’t shoot more than a few rounds before having to take a break due to the pain caused by grasping the rifle with his support (injured) hand. He doesn’t seem to have any issues with using angled fore-grips and I decided to try and make his 10/22 more comfortable. My design guidelines are as follows:
1. Must provide for a noticeable and significant improvement in usability and ergonomics
2. Cannot modify the stock in any way (No drilling holes!)
My first prototype is a slide on (from the front) which fastens to the stock using the existing barrel/stock fastening screw (A bushing was pushed into the counter-bore to provide a secure fit) and with two clamping screws in the front. It will get its first range test this weekend. The barrel band pictured is installed backwards, the rounded bottom edge faces towards the muzzle, it’s designed to fit a small pistol sized light/laser.Learn More
It has been quite some time since I have last posted. The new site is up and running but needs a lot of work. I’ve tried to put up pictures for each project page and will be working on finishing each page in the coming weeks. A lot has changed since my last post, I continue to be embarrassed with the “Top Engineer” casting video, the show never even aired so it was all for naught. Since my last post I have changed jobs, moved into an apartment with my better half, rescued a puppy from a local shelter, bought a laser cutter, got a 3D printer, built an enclosure for my CNC mill, ran a team that competed in the Red Bull Creation contest (2013), and turned the dining room in my apartment into a work shop. Here are a few pictures, many more updates to come.
