This is a set of scripts that uses Golly (see golly.sourceforge.net/), a cross-platform cellular automata engine, to create objects that represent the evolution of a pattern over several generations on the Z axis using the rules of Conway's Game of Life.

The scripts generate OpenSCAD (see openscad.org/) programs, which you can use to create STL files for printing.

The demo object represents eight generations of evolution of a glider.

I've been working on this for several months and after seeing a stock AR lower uploaded yesterday (with no attribution provided), I decided to post mine in order to provide proper upstream credit where it is due. This receiver is based on the IGES file from Justin Halford's superb CNC Gunsmithing site: cncguns.com/downloads.html

[edit] I see KingLudd has now credited Justin's site as the origin of the solid model - thank you.

This is a near fully printable 5.56mm X 45mm or .233 REM AR-15 magazine. It is current only a 5 round magazine. I left my printed spring design out on purpose for saftey reasons. However, with a little printing experimention and some range time it can be made easily.

What is included is the magazine body, anti-tilt follower, and floorplate.

I have used this magazine, no jams or feed problems..... YET. It works, but be reminded it is only a printed ABS magazine. If you end up using a printed ABS mag spring be prepared for stress relaxation of the polymer over time, especailly if it is kept loaded over a long period of time.

The mag catch recess on the mag body(I don't know the official term) needs to move down from the feed lips approximately .010"-.015". My friends AR-15 sometimes would not feed the next round after firing. I believe that will address his problem. This will move the whole body up into the mag well approximate that far. Hopefully, that won't cause any issues with the bolt. I will post the fix sometime late tonight or early tomorrow. I apologize.

UPDATE UPDATE (updated 7-Oct-2011 by KingLudd)

UPDATE

It is clear that the answer to King Ludd's question "Is it OK to post functional weapons and weapon components to Thingiverse" is a resounding YES! Thingiverse's operators broke their silence on the whole weapon issue only to make one smug and irrelevant remark here:
thingiverse.com/thing:11730

Of course, this was after they proudly sent two recent weapon-related links over to their friends at boingboing.

King Ludd's only humble request of Thingiverse is that they remove item 5 from the Guidelines on the upload page. Item 5 states "Please don't upload weapons. The world has plenty of weapons already." The actions and official policy of Thingiverse are in clear contradiction to this line item. This self-contradictory message serves only to confuse users and foment conflict between those that like weapons and those that do not.

If Thingiverse is happy to host weapons, and it is clear that they are, then they should have the decency to present a consistent message to that effect.

With that out of the way, King Ludd would like to say that he is really happy he posted this file. It is something he has been thinking about since crank posted his magazine follower way back when:
thingiverse.com/thing:6646

The Ludd has learned a lot from the many (seemingly well-informed) responses.

Favorite new thing he has learned about? This AR-15 Lower Receiver milled out of a plastic cutting board:

King Ludd is looking forward to seeing the first 3D printed AR Lower in action! Bonus points if you design it in openscad, and please post videos from the firing range!!!

CREDIT FOR SOURCE FILE
The source file came to King Ludd in a torrent package that contained much firearms related material. The source filename is ar15lwrmach_asm.igs and the author was not attributed. It was converted to STL by King Ludd. After comparing the source igs file to the AR lower found on cncguns, it is clear that while the filename and size are slightly different, the solid geometry is identical, so all credit should go to the good folks at cncguns.com. Please visit them if you are interested:

For those unfamiliar with the American cult-of-the-firearm, an AR-15 is a popular semi-automatic rifle that can easily be purchased by well-behaved citizens in the United States. Enthusiasts are drawn to it because it is nicely engineered, reliable, versatile, highly modular, and good for many legitimate civilian uses.

The Lower Receiver is the frame that holds together all the other pieces of the firearm. In the States, all the other pieces can be purchased without a permit - over the counter or through the post. The Lower Receiver is the only part which requires a background check or any other kind of paperwork before purchase.

Typically this part is made of aluminium. A rifle with a Lower Receiver made of plastic can be perfectly functional.

King Ludd is posting this part as a response to all the people claiming that crank's nicely done AR magazine over here is harmless:
thingiverse.com/thing:11636

If it is OK to post a magazine, is it also OK to post a Lower Receiver? After all, it is just a hunk of plastic, right?

What about the other components? What about a high-capacity magazine? What about parts for a full-auto conversion? At what point does Thingiverse classify something as a weapon? Personally, King Ludd does not care where the line is drawn, but he thinks it would be nice if Thingiverse clarified where that line is.

Please enjoy the file. Do not attempt to make this part unless you are certain you are not breaking the law.

Here's my contribution to the fun. A grip for the AR-15.
Grips are a highly personal bit... some people prefer A, others B, and some people can only use C, hate B and tolerate A... Solidworks file attached so you can edit the grip to your own preference.

The Saleae Logic (http://www.saleae.com/logic/) is a wonderful little thing, but the test clips come in a ziplock plastic bag, and I wanted something a bit nicer and sturdier, so I made this!

It assumes 3mm thick perspex.

Who hasn't wanted their own TARDIS at some point? The Old Girl (or Sexy, as she prefers to be known) can be yours in miniaturized form, complete with light on top.

This micro-TARDIS just looks small from the outside (5cm tall) - there's a lot more going on inside.

---TARDIS Blue---
To get the best colo(u)r, I recommend printing with blue ABS, and covering it fairly evenly BEFORE printing, with a blue Sharpie. This changes the print colo(u)r from blue to dark blue. (Approx 0073CF to 0000B8)

---Bits and Pieces---
You will need 1x 5mm LED (in white, blue or UV), some wire, 2x small cell batteries, and an empty drinks can (or similar).

I've got some smaller LEDs coming in the mail, and I intend to get this small enough to attach to one of my infamous hair clips. The photograph shows my iterations, but it looks a bit like the TARDIS is moving through time in a way that only Baker-era special effects could claim ;)

Printed Parametric Chainmail

I've been wanting to try this for a while. This is a sheet of interlocking rings, printed in place. The rings are basically square, with cut off corners. Two sets of diagonals cross each other at different heights, with four posts at the corners. Well, it makes sense when you see the pictures!

This is the first thing I've designed in OpenSCAD, so the code is probably pretty sloppy. The major parameters that can be changed are the layer thickness and line width, along with ring size and number.

I searched for "chainmail" on Thingiverse and the only result was a post by Vik on the Interlocking Rings thing: "Next, chainmail. Right?" So I hope you like this, Vik!

Like bears, the Colberabbit is also a godless killing machine.

At long last, everyone in the world (ok everyone who has access to a 3d printer) can have their own bust of America's greatest entertainer and statesman, Stephen Colbert.

Even better, you can use this model and your favorite 3d modeling software to add Mr. Colbert's face to objects which were formerly lacking in Colbert heads, like bannisters, umbrella handles, toothpaste squeezers, and rabbits. (To name a few.)

Made with a Polhemus 3d scanner at the Colbert set on 6/6/2011.

This was a WIP project, a robot gorilla Marionette. I fused some of the joints in order to cut down assembly. THIS HAS NOT BEEN TESTED.

Not entirely satisfied yet with the mean-ness of my katana, I decided to go to town with a revolver too. Here is an iPhone case you can tuck into your board shorts (front or back is fine) and answer calls with a really nasty look on your face (remember to keep your other hand on the katana umbrella).

This is a large (20+" diameter) mechanical clock originally designed to be cut with waterjet. It could be cut also with a laser, if the right materials are used.

the only non-cnc parts are shafts and tubes that go over the shafts, and a few screws to bolt the front to the back.

the design is based on two different wooden clocks from woodenclocks.co.uk/the_clocks.html (Clock 1 and Clock 2). The wooden clocks don't have second hands, but I added one to my design.

The front gear on the right shaft is connected to the ratchet and pawl mechanism and can be used for winding the weight back up again.

Based on an idea I got from MakerBlock, I decided to create a Dalek from the 2005 series. I've used drawings from various groups to create it, so it should be to scale. However, I haven't quite worked out how to attach the eye, plunger, and gun yet, so that will hopefully be in a posted update soon. I could use any suggestions on attaching them!

Thanks

This is a business card that shoots US pennies. It has a little magazine that pops up and allows you to load up to 10 pennies. Then you can just pull back the slide and release to shoot a penny, and repeat until all the pennies are gone.

I've always been a last minute Christmas shopper and it has usually worked out. This year I had a request to get a Connect Four game, but I couldn't find it in stock anywhere. So I decided to make my own version of it.

en.wikipedia.org/wiki/Connect_four

After working like one of Santa's Elfs for a few hours (minus the green tights) I had beautiful Connect Four style game.

Three rotating concentric rings.

Inspired by some laser cut projects on Thingverse I made this crossbow for my son. It uses a rubber band and has the gun lock built into the handle. It will shoot a sucker dart across the kitchen and stick it to the microwave with a satisfying smack.

This is my face. We used the 3d scanner described here: thingiverse.com/thing:1491 and here: abarry.org/stereo to scan and then print the face.

Update -- just printed a new version upside down for much better print resolution!

This kit is hard to make! It's SMD soldering and it's freaking hardcore. We're selling them at just a little bit more than cost because this is for alpha users!

We're going to go into production on these and they will come mostly assembled. We are just selling these as alpha kits.

There is no guarantee or warranty at all. Bre has made four of them and three of them required a lot of fussing with the soldering until he got rid of all the solder bridges.

Specs:

* Atmega328 chip with Arduino bootloader on it.
* 6 pin header for bootloading. Also includes access to 4 I/O pins and power and ground
* 6 pin header for programming.
* 4 pin extension header for plugging in other things like sensors or shields that extend the watch.
* 16mhz crystal.
* Piezo buzzer
* 3 pushbutton switches

It has 12 LEDs to mark the hour and 12 LEDs to mark the 5 minute marks plus an extra 4 LEDs to mark the 4 extra minutes that aren't shown. So if it was 12:04 the hour LED in the 12 position would be lit up and the Minute LED in the 12 position would be lit up and the 4 extra minutes would be lit up to show that it's 12:04.

Besides having it work on a watch, there are a number of other possibilities because it's an arduino environment on your wrist!

You will need a TTL Cable and USBTiny programmer to program this kit. (Available here in the MakerBot store.

Documentation is available in the wiki at wiki.makerbot.com/makerbot-watch

We ordered a bunch of prototype boards and I've made them into 18 kits and put made them really cheap to just get them out there in the world and get friends playing with them. This is for alpha users because it is realllllly hard! I have soldered up 4 of them and 3 of them had major solder bridges that made me swear a lot. Be prepared for a serious smd challenge!

Nope, not Dash Rendar, Ponda Baba, or even the young Lando Calrissian. It's your favorite smuggler Han Solo lovingly packed in carbonite for convenient shipping and storage. Enjoy Han Solo by yourself or with friends. Han makes a lovely conversation piece and will be certain to make you the center of every party.

SSS (servo suspension system) is designed to support standard servo motors and act as a basic suspension. It is still a work in progress and has not been tested yet.

Will update results soon.

This has been a relatively useful project for me. This wire rack holds two rows of up to 7" wire spools or 12" spools if you decide to cut out an additional base piece. It's primarily constructed from 1/4" ABS sheet with 1/2" electrical conduit to hold the spools. ABS sheet generally comes with one textured side (which you might be able to see in the photos) and one flat side, and it's pretty resilient stuff. You should also be able to stack these racks and bolt them together, but I haven't built a second one yet to see how well this works.

This is a toothpick for a standard size swiss army knife.
I'm not able to print it, so I'm not sure if the curve on the top part matches the curve of the knife casing. If you make one I would be grateful if you post a close up picture of the toothpick in the knife.

It is 5 cm long.

Update July 12 2009:
Changed name so it would be accurate after being truncated.

I've modded a Rock Revolution drum controller to work with an MSA-P MIDI decoder from highly_liquid so I can play on a real electronic drum set, in my case a Roland TD-3SW . Additionally, I've come up with a way to trigger the cymbal sounds (hi-hat, crash and splash) in Rock Band 2 during freestyle, fills, and big rock endings.

With this mod you will be able to play all four games Rock Band (RB1), Rock Band 2 (RB2), Guitar Hero World Tour (GHWT) and Rock Revolution (RR) on a real electronic drum kit such as a Roland TD-3 with full song charts:

* 4 lanes plus bass pedal in RB1
* 4 lanes plus bass pedal with cymbal sounds during fills in RB2
* 5 lanes plus bass pedal in GHWT
* All 7 lanes (6 pads plus bass pedal) in RR

First of all, why Rock Revolution?

I may be one of only a handful of people on the planet that actually think Rock Revolution is a fun game. From a drummers standpoint, the ability to have 6 different pads plus a pedal on the song charts sounded like a lot of fun, and it definitely is. Additionally, I wanted to use just one modified controller that gave full chart mappings in each game. The Rock Revolution drum controller easily achieve's this goal. It is compatible with all the games that have released at this point, and gives full song charts with each game.

Hasn't the MSA-P mod been done before?

Yes it has. I do not take credit for coming up with the idea to use an MSA-P. To the best of my knowledge, this was the brainchild of a couple guys on the rockband.com forums. In fact, I originally followed their instructions from a rockband.com forum post to mod my RB1 controller.

My mod for the RR controller is very similar to the MSA-P mod for the RB1 controller. All that I really had to do was locate the correct solder points for each drum pad on the Rock Revolution drum controller's circuit board, and I was in business. I also took this one step further and developed a completely new circuit that when wired to the MSA-P, enables the cymbal sounds in Rock Band 2.

Doesn't RB2 already have cymbal sounds?

Yes and No. With the original RB1 modded controller, it was possible to map more than one pad on the real electronic drum set to the same color. For example, I had blue assigned to both the second rack tom, and also to a cymbal. Same went for yellow and green also. This allowed for more realistic drumming because you could now play the cymbal parts on the cymbal pads and the tom parts on the toms. However, in the drum fills and big rock endings, all you got were tom sounds no matter what pad you hit. Hitting a cymbal and hearing a tom sound can really break the sense of realism.

The other day while hacking at NYC Resistor, I realized I was getting a crick in my neck sitting hunched over at my laptop. I needed some sort of laptop stand to get the screen up higher, and one that I could get my external keyboard under so my computer wasn't too far away. I'd never seen exactly what I was looking for, so I figured I'd whip one up!

A little while later, with some help from Inkscape and our Lazzzor, I had this laptop stand.

Because the stand is made from 3 flat pieces which you can take apart, it's extremely portable and light.
