Rotary magazine

So I've been trying to build again. I had an entirely different project in mind but I noticed that the teeth of gears fit into the grooves of rods. I was experimenting with it quick to see if a gear would make a decent pin lock (it doesn't). I kept toying with it until I went off on this entirely random tangent without planning on it, hence the mismatched colors for the one slot connectors.  Anyway, this is a rotary magazine. Similar to a drum magazine, it's just a magazine in cylindrical form factor rather than a linear form factor. I'm not sure if anyone was able to successfully make one before. This version in particular stores 12 usable blue rods and one extra one that can't be fired. It has a ball joint connector to act as a paddle to help ensure the rods continue feeding without skipping teeth. I don't have many dark grey connectors but otherwise I'd scale this up using red rods and then store yellow rods. It'd be more useful as it'd fit more nicely with a connector body. Currently to maximize ammo use, I'm trying to fire directly from the magazine without feeding it further vertically. The problem is it's obviously an awkward fit. If you imagine a typical 5 layer gun, it'd fit in between layers 1-2 and 4-5 about halfway each. It's entirely doable, but just doesn't look too pretty.   It's nice in that it allows you to store a fair amount of ammo in a relatively compact amount of space, but it's otherwise not a practical storage solution as is. Aside from just trying to figure out how to attach it to a gun, figuring out how to reload it conveniently would be difficult. It -might- be more useful if it can be turned into a roofed, removable magazine. Then at least you can preload them first.  I hope someone can give a weapon that uses this a shot. Perhaps a bolt action for better performance. And again, I'd scale it up to store yellow rods so it's a little easier to use in a standard connector body.  Here's a quick video demonstration and a look inside it at the end:

Which rotary tool?

I recently got some money from the government for my good grades (YAY!) So now I can get myself a nice rotary tool. BUT I can't seem to make a decision!

Wen 2307 Rotary Tool - Help needed

Hi there everyone, I need a bit of help if available. I purchased a WEN 2307 101-piece rotary tool set from Amazon.ca a few weeks ago and followed that purchase with a Flexible Drive shaft.  Although I was able to attach the drive shaft to the tool, the bits that came with the WEN don't seem to fit the collet of the drive shaft properly.  Therefore, I am planning on returning the drive shaft and purchasing a different unit from a different supplier on Amazon. The unit that I am considering is an SPTA Electric Grinder Flexible Flex Shaft Rotary Tool Attachment 42" Length and Rotary Accessory which states that it fits All 1/8" rotary tools. Of course, the drive shaft didn't come with a manual, so I figured out myself how it is supposed to attach. I'm not very familiar with rotary tools and purchased this unit as a beginner, instead of spending a lot of money on a really good Dremel. That being said, I would like to know if the size of the collet is equal to the same size bit.  (i.e., if the rotary tool is fitted with a 1/8" collet, do you use 1/8" bits, or do you use a different size? I know that this seems like such a stupid and/or easy question to most people, but, being a beginner, this can be quite confusing. Any assistance that you can offer will be greatly appreciated. Thanks

Rotary (pot) to mouse emulation

I am trying to create an autocue controler. (I've built all the software in Javascript to run in browser windows) When you press a button in Firefox / Explorer, a circle with 2 arrows appears allowing you to scroll up and down. If you move the mouse, the speed of the scroll changes. I want  - if not too complex - emulate this behaviour externally. My idea is to have a rotary control replace the mouse mvement such that you turn it one way the screen scrolls up, and ditto in reverse. And the further you turn the wheel one way or the other, the faster / slower the scroll goes. I did think about using a PS2 mouse thinking it would be a simple case of replacing the sensor, and sending pulses to the chip to emulate the encoder output. But now I understand the LED in these sensors is pulsed, and that the encoder also generates a quadrature signal to the IC chip. Apart from which, those mouse / IC chips are now obsolete!! Anyone any ideas? ** In the days of serial on the old PC's like ZX80, you simply sent a pulse to emulate a mouse click: rapid fire was simply a matter of increasing mark/space timings

Mouse wheel. How do I replace optical encoder with rotary encoder?

Hi, I have a Belkin Nostromo N52 controller. It has a mousewheel that can be custom programmed independently from the wheel in your regular mouse. I want to use it as a jog dial so I want to remove it from the original place and replace the rubber wheel with a jog dial. Basically it is to rotate the wheel 90 degrees as they did here with a mouse: https://www.instructables.com/id/Desktop-Scroll-Wheel-and-Volume-Control/?ALLSTEPS The problem is the Nostromo wheel uses an optical encoder instead of a rotary encoder (the typical used by half of the mouse wheels in the world). The mod I want to do would be a little complicated using the optical encoder (I would have to use a piece of PCB perpendiculary soldered to the main PCB and the height of the resulting device would be very tall for what I want) but it would be very easy if I could replace the optical encoder with a rotary encoder I salvaged from a mouse since it can be laid down on the PCB pretty well. The problem is the signals of the optical encoder and the signals of the rotary encoder are different. The middle leg of the receiver in the optical encoder is connected to +5vcc while the outputs are connected to ground using 10KΩ resistors. In the rotary encoder, the first leg is connected to ground and the other two go directly to the mouse IC. I tried to remove the optical encoder of the Nostromo and connect the two outputs of the rotary encoder to where the outputs of the IR detector go and the third leg to ground but all I get is a permanently actived scroll down (as if the wheel was scrolling down all the time). I didn't dare to connect the third leg to Vcc just in case I blow the thing. I think there must be a way to replace the optical encoder with a rotary encoder and get the same signals and I think this involves using the Vcc line and resistors but since I'm not very good at the electronic side of things, I don't know how to do it. I'm enclosing a diagram of the optical encoder circuit. The diagram on the right enclosed in question marks is what I guess would be the equivalent circuit for the rotary encoder but I'm not sure. Can anybody confirm it or point out the appropriate corrections? Thank you.

How can I modify this circuit to sequentially turn on LEDs in parallel, while avoiding voltage drops? Answered

I have a single pole, 12 throw rotary switch which I want to solder to a set of LEDs so that rotating the switch clockwise lights more LEDs as follows: 1 = 1 Red LED 2 = 2 Red LEDs 3 = 3 Red LEDs 4 = 4 Red LEDs 5 = 5 Yellow LEDs 6 = 6 Yellow LEDs 7 = 7 Yellow LEDs 8 = 8 Yellow LEDs 9 = 9 Blue LEDs 10 = 10 Blue LEDs 11 = 11 Blue LEDs 12 = 12 Blue LEDs Since there will be a voltage drop across the diodes, the LEDs at the start of the chain will get progressively dimmer, and increasing the voltage would blow the LEDs in shorter chains. One modification I know I could already make would be to not use the first 4 diodes on the yellow LEDs, and the first 8 diodes on the red LEDs, as a minimum of 5 yellows and 9 blue will be active for each position. This still leaves a maximum of 3 diodes in each chain, which I still think would cause the lights to be much dimmer. Another solution I can think of is to have multiple wires coming from each terminal of the switch, each with their own diode, which would ensure all active LEDs had the same brightness (I'm not sure if this would cause the whole chain to be dimmer than shorter chains or not). The downside is this would need  31 wires rather than 13, and that's only if I bridged together all the shortest LED chains of each sequence: individual wires for absolutely every position would mean 79 wires+diodes). To put this in context, I want to create the health bar from Dead Space 3: If you can suggest a way of improving the circuit, or totally re-designing it, it'd help me loads! Thanks!

Rotary switch w/ direction based contacts??

I'm looking for a specific type of switch... I believe that it must exist, but I have never seen it... I need a rotary switch, where each clockwise "click" (partial turn) makes one circuit momentarily, and each counter-clockwise turn makes a different momentary conection... example with two light bulbs ( L1 and L2 ) connected to each direction of travel, respectively: If you rotate the knob one "click" (say 15 degrees) clockwise, L1 flashes for a moment, as the knob is in motion. if you continue clockwise, L1 will flash at each "click". If you rotate the knob one "click" counter-clockwise, L2 flashes for a moment. if you continue counter-clockwise, L2 will flash at each "click". There is no center-point, so any clockwise travel corresponds to L1, and any counter-clockwise travel corresponds to L2. does anyone know where I could get a couple of these??

Bolt Action Rotary Magazine Gun (updated with internals)

Alright, it's been a while, forgive me. I work in spurts of an hour or two every few nights. It's not quite finished, but it's at a point I'm comfortable showing. I'm also working with BM, so hopefully he can make some improvements on it before it's posted. This gun is the combination of two different goals I've had. First off, I always wanted to make a bolt action. I came up with the idea for the modern bolt action long ago but was beaten to the punch. So since then, as others have made their own bolt actions, I still struggled to make one up to my own standards. I wanted something sleek and compact with a removable magazine. Second, I went off on a little tangent while building, which then turned into its own project: a rotary magazine. While it's been done before, I don't know if it was ever successfully used in a gun. It's more about the novelty than the practicality, but what it does do is give you more storage in a compact design and act as a decent foregrip. I wanted to make it a decently usable. At first I thought of making just some cruddy gun to show off the concept as a usable magazine, but then I decided I may as well go the full nine yards and make it perform well. So this is what I ended up with. I don't have a real name for it yet, but I've considered calling it the Barackuda, a portmanteau of Barack (Obama) and barracuda because...well why not. I wanted to keep it as compact as possible, so I used a barrel similar to my Oodassault 3 series and a stock connection similar to my PDR. The stock is a bit long compared to the body of the gun, so it may look awkward, but I wanted to give at least enough room to aim the gun without sticking the pin into your eye. The blue connectors in the stock stop the bolt right after the trigger engages. The bolt is somewhat typical. I like how it sits flush with the back of the gun rather than looking like an extension on the back of it. The handle isn't amazing, just a variation of my tried and true handle I've come to like. The trigger also isn't amazing, and in hindsight, I want to block a bit further back still, but it works for the limited space I've got. The magazine on the other hand is magical. Go look at my last topic for details on its operation. This version is for yellow rods. I've added a rotary lock and band. When the middle rod is pushed toward the trigger (like in the pic), it's locked. It can securely contain 10 usable yellow rods while locked, though it can load up to 12, the top 2 can fall out. You insert it into the gun by pressing the top two red rods at an angle into gaps in the grey connectors at the front, then rotate the magazine, slightly pushing in, until you get the white rod in the gaps of the yellow connector. Finally, you push in the middle red rod by the trigger all the way forward to unlock the magazine. Edit (9/10/2015): Made my adjustments and now I'm mostly satisfied with the weapon. Here's the video.

123D Design Vs. Rotary Tool. What is better?

When Instructables gave me the opportunity to be part of its Artist in Residence program, one of the first things I thought was "Blimey!* I don't know 123D or any other design program. What am I gonna do?" (*Of course, in my country we don’t say “Blimey!” but something ruder. But I think you get the point) Let me introduce myself: I'm Mario Caicedo Langer, from Colombia (not "Columbia"). Former Colombian Navy Officer, BsC in Naval Sciences, maker focused in trash art and upcycling. You can see my Instructables profile here. My skills: I can transform almost every piece of e-waste and plastic trash in something useful, decorative or funny. My weak point: the only design program I used in my life was... Paint. Yes, that Paint. So 123D would be my first experience with a CAD program. I have to be honest: I'm not a big fan of CAD programs. Yes, they are awesome. But I am an old school maker who loves to use his rotary tool and his screwdrivers to build stuff, at risk of his own hands. I thought CAD programs were reserved for industrial designers or engineers, even one like 123D Design, developed for the DIY community. THE EXPERIENCE A few weeks ago, on a Friday afternoon, I finally decided to take a look the 123D Design installed in my PC. So I started to play with the program. When I got stuck, Randy Sarafan gave me some useful tips. Two hours later, I finished some kind of robot arm. At night, I had finished a "chicken legs" robot. On Saturday morning, I had a futuristic motorbike. On Sunday, I was at the beach in San Jose, eating Deep Fried Twinkies, but that’s not important. By Monday, I had my fourth project ready (not my best work, but still) for the "Show and Tell" meeting at Instructables. I finished my instructable on how to make a transformable robot, my first 3D printed project. And right now I'm working in a futuristic jet. I'm not saying "Oh! I'm a genius! You’d better make a movie about me! (In this case, I want to be interpreted by Ryan Reynolds or Samuel L. Jackson)". No. What I'm trying to say is that, sometimes, we have the tools at reach, but we are too lazy, too coward or too old fashioned to try them. And Autodesk is giving a great tool to the maker community. It's a friendly program (I don’t know how it could be friendlier. Telepathic commands, maybe?) and you can learn it in one weekend or less. It doesn't matter if you are a professional designer or not, you only need two things: the will and visual-spatial ability. And you only get the second thing by being curious about all the things around you: touching, dismantling, cutting, breaking, attaching, opening, destroying and rearming stuff. And, if you are a maker, you are on the right way. 123D Design is an awesome program (and honestly, the only one I learnt), I love it and it's free, but it has two aspects to improve. First, fonts could be very useful. What if I want to 3D-print a plaque with my name? Second, I don’t know if it’s because of my computer, but sometimes the program crashes and, if you didn’t save your progress, you will have a very bad time. So I got the habit of saving on my computer every 4 minutes. That’s all. AT THE END Right now, I’m asking myself “Myself, what do you prefer: a carpal tunnel syndrome for using your computer or a severed hand syndrome for using your jigsaw?”. Then I remember my wise mother telling me “Mijo, don’t say those barbarities because there is no idle words”. Resuming, what is better for a maker, CAD/CAM or traditional crafting? I believe there is no competition, because both are complementary. It’s all about what do you want to do, how do you want to do it and what is the best option for your project. There are a lot of things you will never achieve without a computer. But there are a lot of things a computer won’t be better than the human hands, too. And building stuff with your very own hands is a very rewarding experience. So, it’s up to you! Because for me, 123D Design became just another tool in my toolbox. A powerful, fantastic and awesome tool in my toolbox.
