Building a lighted trackball!

I saw a guy at Starbucks using a lighted Trackball with his laptop about six months ago. I should have asked him where he bought it, because I've been searching for one ever since and it's "can't be found!". I even searched at the Consumer Electronics show in January; nothing. Nothing online. So I'm going to have to BUILD one! The trackball he was using had a clear plastic case, and it flashed blue as he moved the ball. You can buy translucent trackball assemblies (for games) where the ball is lighted; but that's not what I'm after. The optical trackballs operate off an internal LED, it may only be necessary to expose that by making a clear plastic, or colored (blue?) plastic case; I'm not sure. Any suggestions or know-how would be much appreciated! I would try to build one if I had enough information. -steve

Novelty Car Horn - Help!

I bought an Ooga horn, and a button wiring kit, but i'm having some trouble...First off, there's no relay, should there be? Also, do i need to buy an additional toggle switch?

Giant Gourd Case?

I like watching Naruto and one of probably everyone's favorite characters is Gaara. Gaara carries around a giant gourd on his back and I figured, why can't I? I thought about making a snowman out of beach balls as a mold and covering it with paper mache. Using that as a base I was wondering if anyone had any ideas on how to harden and waterproof the case. I thought about layering fiber glass or using plaster, but I'm not sure how heavy it would be. I also planned on making compartments, one on top for general storage and one on bottom with interchangeable parts like a speaker and a drink container with a tap. Eagerly open to suggestions. : )

Is it possible to turn a small, novelty windmill into a generator?

The windmill is very small - probably about five feet tall, judging by my own height. It is very simply four posts holding up a rotatable windmill / fan with a tail. Both the fan (the blades) of the windmill and the entire top piece (the fan and the tail) rotate. It is a little rusted, but still works perfectly - as evidenced by the creaking and squeaking we heard on a windy day! It can work up quite a bit of speed. Unfortunately, due to the wind, we also get a lot of power outages. I don't expect that such a small windmill could power an entire house, but if it could power a computer or a freezer/fridge we'd save a LOT of money -- every time the power goes out my mother's computer fries and all the food we just bought goes bad. Is it possible to turn this into any sort of generator? (The windmill is outside and while we DO have windows leading in I don't want to encourage any critters. HOWEVER the windmill IS near a door from our garage that no longer opens, but does have an old, unused dog-door.)

DIY Protective Helmet? Answered

So I'm looking at starting a helmet project with the good ole' pepakura halo helmets, but taking it a step further. Essentially what I am wondering is how one would go about adding some protective foam or padding that can absorb impact (I'm talking motorcycle grade here). The design I'm looking at calls for some custom work, otherwise I'd just gut an existing helmet off the shelf. Does anyone have any ideas on accomplishing this? I'm thinking the helmet shell will be carbon fiber for added durability so I'm hoping to get some feedback on what everyone thinks would be the best protective layer for the inside. Also, please no "For your own safety just buy a helmet and don't worry about the looks" This is a novelty just for fun, but I'd like to know I could use it if I wanted to. Let me know what you think!

Wire only (no PCB) Speaker in clear resin ball.

So I had an idea to recycle on old speaker into something a bit more aesthetically pleasing.  Firstly I realise this will not improve it in any way   and over heating may be a serious problem but I never use the speakers and want to make this mainly as a novelty item rather than best functionality. What I had in mind was taking the speaker amp apart and resoldering all the components with wire rather than using the pcb, this would then be set in a clear resin ball with volume control, jack, power and cone sticking out. Firstly what would be the best way to prevent all the exposed solder contacting, Hot glue? Next what is the best resin to use, for clear resin I only know of polyester, is this best? If so are there any kinds of mould material that cant be used with this type of resin? Lastly could anyone suggest a way to ensure that all components are completely covered (i dont want any bits sticking just above the surface as it would ruin the look of it.) Thanks for any thoughts!

Gaming is Changing

I used to like console gaming because systems rarely/never costed more than $300, it was simple, and everybody had the same stuff. There were no expensive HDTVs, broadband-requiring/expensive online play, the fanciest peripheral was the rumble pack, and your console didn't do anything except light up a power light if there was no game in it.I'm not rich, my parents have never owned a house, and with all the fancy crap that consoles require and do today, I can't afford even a Wii (not that I'd want one, the novelty has worn off). I'm not saying all these improvements in gaming are bad, but for someone like me, I just don't have the money for a shiny new 360, or even high-speed internet (I live on an acerage and there's no cable in the country) for online muiltiplayer/communication.For now, I'll just have to fondly remember having home tournaments playing Star Wars Episode 1 Pod-Racer on N64 with my friends.What do YOU think about gaming today?

How can I trigger an LED sign to turn on when an object is tossed into a bucket? Answered

I am designing a bucket with a small LED sign on it, and I want the sign to light up when people successfully hit a target in the back of the bucket. Everything has to run on battery power, and the entire product has to be mounted on a pole (which will be held in hand). I have considered motion sensors (Parallax PIR) and some sort of laser trip-wire (as one would find on a garage door system), but I am not sure how to implement either.  I have also looked into shock sensors, the kind used on some window and door security devices, however, I am not sure that the objects being thrown would be able to provide the shock needed (think toy cars, beaded necklaces and other small novelty toys). The sign will consist of up to 200 LEDS, and it would be nice to have it stay lit for a second or two before turning off again.

Tyre table

Hello I have an idea surrounding a racing car tyre which i was given for nothing, as a racing car fan i though this was brilliant. However after the novelty was worn off i came to the conclusion that i have nothing to do with it. I have came up with a use after about a year of it sitting at my parents house, i want to create a table based within this tire, the most basic thing i am wishing for this is a circle of glass to act as a table top, however this idea has developed and i would like to have this top removable if possible where there is another plate of glass on which i could put things, the final evolution would be for this table to light up also, preferable with its own power supply but if this is not possible then mains powered would be no problem. another option i was thingin is if the top of the table was able to be pushed down to turn off/on the light. If anyone has any suggestions of materials and/or components that i could use this would be a great help as i am stuck at the moment. I am unaware of even the typer of glass to use! LOL Many Thanks in advance for any help i receive Matt

recording photo frame mod to mini amp/speakers

I bought a little recording photo frame at Walmart tonight for $2.88. Sadly someone had been testing it and the batteries are dead, so I can't check the volume til I can get new ones. What I'm wondering is whether anyone had altered one of these or something similar to make it mini amp w/speaker. I'm wanting to install something like this in some small stringed instruments(dulcimers) I'm making that don;t have much volume on their own. I've looked at all the altoid ideas and mini amps and mini speakers, but didn't see anything that would do what I need. Most were just for ipods. I did see one that used a spy ear and that's what gave me the idea for this. I have one of the cheap little clear plastic spy ears somewhere, but couldn't find it tonight I would be ok for picking up the sound, but I don;t think mounting the earphones on the instrument would give enough sound. The soundbox on my larger. dulcimers did ampllfy some earphones I got at Dollar Tree, but not much. I would add pics of the circuit board of this recorder, but my camera is dead. I would really appreciate any help with this. I need to keep the cost down as much as possible in order to keep the dulcimers affordable. The ones I am making are more a novelty item, so I can't price them too high.

Just HOW contraversial is this really? (Also: The Dunkis's Flat knex pistol review.)

I know this subject has been brought up before, but I'm the first one to actually have video documentation on this topic to my knowledge:  While I'm at it I might as well review TD's Flat knex pistol because I don't feel like making a separate topic for that: Design- 7/10.  It succeeds at being compact and flat but this results in some tradeoffs, such as a tiny handle.  Bullet lock does not work too well, the ammo falls off given a good shaking. Range- 6/10.  About 25 feet with oodammo, with 2 #64's.  Any more bands, and I have problems pulling the trigger.  I'm gonna go easy on this rating because it's a compact gun for showing off. Comfort- 7/10.  Sure the handle is flat, but it's also tiny and pretty hard to grip if you have larger hands.  Also the pin tends to hit my hand a bit if I'm not careful due to this. Innovation- 8/10. It's the first truly flat knex gun, but it also sacrifices functionality. Trigger- 8/10.  It blocks near the back of the barrel, but the part you pull breaks easily with more than 2 bands.  It's comfortable though and the spacers don't fall off. Overall- 7/10.  It's a novelty show-off but nothing too powerful.  Great for stealth if you ever needed to hide it.

Am I A Reverend ? ( UK only question ). Answered

Hello, I was given this certificate as a Christmas present. I thought it was just a novelty but was assured that I could, if I wished, now sign legal forms/change my bankbook/change my passport to utilise the prefix Rev, because this is an officially recognized church. I was overjoyed but very, very skeptical. I Googled but can only find one site under The International Church Of Atheism, which is  very basic and without contact details. http://internationalchurcho.fatcow.com/ Reading around the subject it seems that this kind of thing is legal in the US of A ( such as the First Church of Atheism ) and even allows you to perform weddings but I can't find any useful info on how much weight this carries in the UK. I know that it will not give legal status to performing marriages or any heavyweight duties here but I do like the idea of having Rev. on my driving licence; would anyone know if it at least allows that ? Does anybody with actual legal knowledge know ? No guesses or opinions please, I've found enough of those while Googling. Thank you for your help. Rev. Friend Of Humanity. UPDATE After Kiteman's comment I feel that I should state that I Photoshopped my real name out in order to illustrate this question. And just to clarify: I am asking if I can legally use this prefix on my passport etc. I do not have any plans to use it in any practical way such as performing/witnessing marriages.

This, From That - Maker Faire and Instructables in the New York Times

Instructables and Maker Faire received some nice coverage from the New York Times article This, From That."This is a real geek fest," says Professor Schalk, a high-energy physicist in both senses of the phrase."If I was a kid, I'd wet my pants here," he joked.Some 65,000 people came to see the sprawling display of inventiveness and potentially hazardous fun. Many of them read Make magazine and its sister publication, Craft, and go to Web sites like Instructables.com that encourage people to take on projects and share what they learn. (Recent online projects have shown people how to convert a novelty French-fry telephone into a carrying case for an iPod; how to make a computer-powered coffee warmer from an old Intel Pentium chip plugged into a P.C.'s U.S.B. port; and how parents and children can build a small vibrating robot together.)By far, my favorite quote from the piece:"It's deeply American," said Xeni Jardin, an editor of BoingBoing. As for the family-friendly setting, she said, "It's like Burning Man without all the icky hippie elements, without the pants-free guy on a bike."And more:Roxanne Stafford, a designer who visited the Faire without knowing much about it, said she was "a little overwhelmed" by the size, the variety and the noise.She added, however, that she found an underlying message in it all. With the ghastly images from the Iraq war and the uses of technology that usually make the news, it is easy to conclude that people simply make things and use technology "to destroy one another," she said."Things like Maker Faire give people hope," she said. "Creativity is the best expression of humanity."More press about Instructables here.

GID Vials, Tritium, TRASERS, Powders and Chemicals GLOW IN THE DARK!

TRITIUM! So I get a lot of questions from my post and instructables. Tritium Vials are Radioactive Hydrogen H3, also known as hydrogen-3 is a radioactive isotope of hydrogen. It is contained in small glass vials coated in colored phosphor then encased in glass or sealed plastics. These are commonly seen in Gun Sights, Watches (TRASERS) and some Emergency Exit Signs. http://en.wikipedia.org/wiki/Tritium_illumination Small amounts are legal and for approved uses. Read the NRC guides Typically the Trit vials are small, expensive and dim. The latest GID (Glow in the Dark) Chemsticks, LED's and GID Powders or paints seems much more effective and usable. * Cyalume, as used in a lightsticks, emits light by chemiluminescence of a fluorescent dye (also called fluorescor) activated by cyalume reacting with hydrogen peroxide in the presence of a catalyst, such as sodium salicylate. It is the most efficient chemiluminescent reaction known. up to 15% quantum efficiency. http://en.wikipedia.org/wiki/Chemiluminescence New LED low power requirements and high Lumen or light output have provided many solutions that are low cost, high power and longer lasting. GID Paint or Powders are "charged" with light or daylight sources as with your traditional kids toys or stickers. New products are brighter, glow longer and are now waterproof, have many colors and applications. http://www.4physics.com/catalog/GIDinfo.php Also this is occasionally confused with the chemical illumination. However these paints powders and materials use common phosphorescent materials include zinc sulfide and strontium aluminate. Use of zinc sulfide for safety related products dates back to the 1930s. However, the development of strontium oxide aluminate, with a luminance approximately 10 times greater than zinc sulfide, has relegated most zinc sulfide based products to the novelty category. Strontium oxide aluminate based pigments are now used in exit signs, pathway marking, and other safety related signage. http://en.wikipedia.org/wiki/Phosphorescence Hope this helps! 01/2011 - Update Source for Materials http://www.darkniteglow.com/glow-shop/ ERCK www.Candlepowerforums.com Additional Tritium Resources * U.S. NRC: http://www.nrc.gov/reactors/operating/ops-experience/grndwtr-contam-tritium.html * U.S. EPA: http://www.epa.gov/radiation/radionuclides/tritium.htm * U.S. DOE (Argonne National Lab): http://www.ead.anl.gov/pub/doc/tritium.pdf * California EPA: http://www.oehha.ca.gov/water/phg/allphgs.html * University of Idaho: http://www.physics.isu.edu/radinf/tritium.htm

All of this , from within australia, i plan on selling things which are awsome, as well as generally inaccessible by many australians. Currently i intent to buy up 6v spark gap ignitors , identical to those on sparkfun, different coloured laser modules, titanium to weld to my MMO anode mesht cuts, more wireless receiver/transmitter pairs, though, this time, toggle/momentary ones, currently my ones are latching, i plan on buying small shockers, and lastly, Nitrates, Aluminium powder, sulfur, and all those chems which are so hard to find in australia.

Casio pocket Tv: Tv-1900B info/suggestions on uses?

I just received a casio pocket television model: Tv -1900b, produced somewhere in the late 80-mid 90's(cannot find year) as a gift from my sister, purchased for 2.99 from goodwill, she bought it because I like vintage electronics, and thought it was useable as she was not aware of the difference between dtv and analog, and took the label heading that it received working channels for true, from my research it appears to be functioning but is receiving no signal due to the dtv transition. this is my problem, I am trying to figure out ways around not having an available analog broadcast to pick up, and can not find much info for this tv model online, not even part labels manuals or specs, Im wondering what my options for use or connecting it to another device are.. There is what appears to be an extra headphone sized jack/connector at the top next to the speaker, and a headphone plug does fit into it... but the label for it is long gone, so I do not know if it is an external antenna connection, external composite video in port, external video out port, or a service port of some kind, as it is right next to the rod antenna  screw connection, what exactly is it, and can it be used for an external video/sound input connection?, I see that  on other models before and after this one it can be used as a video/audio input, when utilized with a rca to headphone adapter cord but that does not tell me for sure if mine has that ability. What are my options with this?, I have some technologic know-how, but could not build my own signal transmitter, oscilloscope, built in jack, etc from scratch. is this model capable of easy external connections?, is the extra hole for an antenna input, video input or both?, can a box, dvd or vcr be connected, also is wrapping wire around the antenna and then connecting to the coaxial output on an external device feasible? Iv seen it work on other pocket tv's on the internet but dont know about the true signal quality/effeniency I would be able to make most physical external connection adapters myself, or, are adapters other then the headphone to rca adapters sold to remedy the problem of having a rod antenna and little to no external hook-ups? p.s I am not opposed to having it constantly wired/tethered to a much larger device, as it would be used for a novelty or in a small area where a larger unit would be to big or unweildy, like next to a bed, spot at the table, etc, also I would probably not use it for cctv or similar as I have little to no use for such things the picture included is not of my actual item, but the same model and version, for reference purposes I appreciate any help, as it appears to be functioning it would be a shame to not find a use for .

But hey, maybe you just lost your job, you're a poor college kid, you're mad at McD's because the dollar menu isn't a dollar anymore, or you're just cheap! Or (in my case) you love exclusive sauces not sold in stores and would like a more efficient way of emptying all those hundreds of sauce packets you acquired into bottles :P Lol, let me go into what lead up to my "Huh, that would be awesome!" idea moment. I love(d) Taco Bell's Fire Roasted sauce. And darn them to heck for discontinuing it!!! Um, uh... yeah anyway. I loved it. Alot. So much so that I eventually built up a large cache of packets in my kitchen. One day it occurred to me I would use it more if the sauce was with all the other condiments in the fridge door. For when I prepare something for consumption and have thoughts similar or equal to "Hm, I wonder what would be good on this" I open the door, stair at the sauces, and evaluate. So, I saved a nice glass bottle (a steak sauce if I remember correctly), washed it, and squeezed many, many individual packets into said bottle until I had my very own "Bottle of Taco Bell's Fire Roasted Boarder Salsa Sauce". A practice I continued for several years. Many of my friends thought it was awesome. Other's thought I was crazy. In the end it didn't matter what other's though. The sauce called to me and I answered. Faced with the same decision I would do it again and I have no shame in that. Just in case you are actually interested, when I heard they were discontinuing my favorite sauce I made arrangements with the manager of the local taco bell to obtain their remaining boxes of sauce. And it was enough to last me until... today. As I squeezed the last few packets of Fire Roasted Boarder Salsa Sauce into its bottle that has served me so faithfully these many years an idea hit me. The concept of a machine that would extract the sauce for you. Pour packets in and sauce comes out. My first reaction was "this would have been very useful several thousand packets ago!" lol. Then I really started contemplating it as a "for the hell-of-it" idea and project. There are just so many different, possible ways of how one might work. Just with the squeezing mechanism (after the packet(s) is somehow automatically slit open). With a double roller one could squeeze several at a time or in serial progression. Or perhaps stack them in the same orientation inside some sort of press. Much experimentation would need to be performed to determine the optimal extraction method. Anyone interested in giving it a go?

How to make a replica of The Riddler's Box (Work in progress)

All right, I admit it. I liked Batman Forever, and still do. I also liked the "Box," which was the film's signature gadget. (And no, I don't count the Batarangs--they're equipment. The Box is a gadget in the purest sense of the word.) To that end, I decided to build a replica of the Box last summer. It's still not finished--I need to work out lighting, a motor, and the lower coils. (EL wire, maybe?) By the way, I'm posting it on the forum first because it's still a work in progress. I have no Monet to buy Degas to made de Van Gogh, as it were... YOU WILL NEED: One clear 28-oz. tumbler, acrylic (I got mine from Jewel for $1 last year...I don't know if they still carry 'em) One 20-oz. tumbler, acrylic (I got mine from Walgreen's last year...ditto) Two super-size cup lids from McDonald's One large bottle of Gesso One bottle of gold paint (Antique Gold works best) One bottle of green glow-in-the-dark paint A really long paintbrush, preferably made of foam A normal paintbrush The wings are made of a piece of foam I had lying around...I need to get them made specially. It's also got some Christmas-wreath lights stuck inside, just for the picture. ------------------------------------------------------------------------------------------------------------ SO: For the 28-oz. tumbler, first you need to thin your Gesso out with water. This will allow you, later, to add the paint in such a way that light can shine through. Then, you will want to paint the INSIDE of the tumbler with Gesso, and then with the green paint. Simple as that. For the 20-oz. tumbler, you can leave the Gesso thick if you wish. Depends on your preferences, really...Then, you'll want to paint the outside of the 20-ouncer with the gold paint. With me so far? Then, you'll want to glue the two McDonald's lids together for a bit of sturdiness. I recommend Gorilla Glue for this. When that sets, you'll want to paint the outside and the inside with Gesso. The outer lid is gold in color; the inner lid is black. This prevents light from shining through the lid, which could give the game away. WINGS: As for me, I cut a pair of 11 3/4" oblong triangles from foam for the wings. They're not stable at all, but at least you get the basic idea of what it is. I stacked the 28-oz. tumbler on top of the 28-oz. tumbler, put the lids on, and stuck the wings on with tape. It's a crude mockup, but it works for now. I put the Christmas-wreath lights inside just make it look like it's doing something. I'm thinking about adding a "Fusion" light from Windy City Novelties for the finished result. The final version of this will involve some very tricky wiring--I want to wire the light-up gadget and the motor to one switch or button. If any of you have suggestions, the mailbox is open and waiting. I've very little technical experience, and would like as much input as possible from anyone who knows something.

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.

My Month at Instructables as an Artist in Residence

It's easy to see Instructables as a single entity who's persona is summed up in one yellow robot. During the month of November I had the good fortune to spend a month as an Artist in Residence at Instructables HQ and had the opportunity to look behind the yellow curtain and learn more about the people who craft the website and the work that they do. During my stay I met artists and technicians, crafters and programmers, and I was allowed to peek into their world and see the inner cogs whirling away. Oh yeah, I was also let loose with a million dollars worth of 3D printers and laser cutters with no more direction than to have fun and make stuff! Day to day life at the office was not what I expected. Before arriving I had envisioned a, well, a madhouse. I figured that there would be 10 ft cardboard robots beeping away in one corner, office supply archery in the other, and paper airplanes gliding over the top of it all. When inside though I didn't find a room of chaos, but a room of people quietly working. I soon found out that between community management, site development, contests and other site duties there is a massive amount of work that goes into making the Instructables DIY hub function. It wasn't all business though, there was certainly time for liquid nitrogen ice cream, communal lunch hours, and pizza Thursday! I am very much a robot / tech person, so one of the highlights of my visit was getting to talk shop with randofo and amandaghassaei, Instructables technology editors. They had the coolest gadgets, and both fit the role of tinkers perfectly. Randofo had a huge bin of motors, gearboxes and other electrical delights that he patiently let me riffle through, and Amanda's work area was mass of dismantled keyboards, wire and test equipment. They practiced a type of electronics where novelty is the main function, and it was amazingly fun to see their projects come together. And yes, of course, the 3D printers were a blast. I really was allowed to dive in and try anything I wanted with the Objet machines so I took every spare moment working with them. I spent a fair amount of time running test prints of the different materials and testing their physical and mechanical strength, (aka breaking them). Once I had a feel for the UV cure pseudo plastic, I had just enough time to print everything I wanted plus some. I should also mention that this same building had two of the fastest laser cutters I've seen, and all the plastic and cardboard I could possibly need for my scale of projects. I can't possibly relate how liberating it felt to be able to think of an idea, draw up the CAD, and have a working prototype in less than an hour. The Instructables office is found on a busy street of San Fransisco, above a deli and a bar that plays full Talking Heads albums. This was my first time in California and I loved every minute of it. There was this creative energy all about and it seemed that there was some kind of art plastered anywhere it could fit. I felt like I was on an expedition, seeing for the first time things that I had only read about; I saw subway performers, photographers, and a silver painted robot guy. I ate at a Kwik Way and bought guitar string from the store that the Mythbusters bought their trumpets from. Not only that, but there are celebrities in California and I'm almost positive that Elton John rode the same bus as me every day. I could be wrong, but he had these huge glasses and the hair cut and everything. (I've never seen a celebrity before.) I visited California for a month but it felt like it flew by in minutes. After giving a small presentation over a Thai lunch and a short goodbye, I left San Fransisco and Instructables with a greater awareness and appreciation of the creative community and the talents of its members. Visiting the office and meeting the Instructables crew was an unforgettable experience and I hope to visit again someday. I would highly recommend the AIR program to any one in the position to participate, I had the time of my life.

TR8-2015 Review

I received my TR from Killerk this morning. I've had a little hands on time with it so I'll write up my text review now, though I'll also be making a video review in the near future. For now, here's the unboxing and first impressions video: So just to start, I've never made a TR before. I have limited experience with turreted weapons. So what I knew about them I only got from videos and other people's reviews. I didn't doubt the TR was a great performing weapon, but I was wondering what all the hubbub was about. After finally messing around with one for the morning, I can see where the praise comes from. I also noted some things I'd still like improved, at least to personalize on my variant.   I'm going to use a grade scheme (because everyone's impressions on stars and scales are usually biased toward higher numbers). So, just to clarify, don't think of C as bad. It's average. I'll point out what's subjective. I'll nitpick a lot of little things, and I'll give credit where credit is due. Anywho, on to the review. Aesthetics: C+ My impression of the TR has always been that it's been a rather simple weapon. I'm a rather hard man to please in this category. The front is a tube barrel construction. I don't care for the looks of turrets because they're rather chunky for the amount of ammo they take up. The stock is a little skeletony. And it seemingly has weird support pieces thrown in random places. But it's not bad. It still looks like a good weapon. The stock has a nice design. It has a relatively clean cut design around the outside. Ultimately, I know most was for the sake of a strong, durable weapon, and I'll be sure to personalize it more.   Ergonomics: D+ This one I gotta be honest on. The handle just doesn't float my boat. My hands are shaped oddly so I've always made weird sorts of handles myself. While the tires are a cool concept, they help keep your grip on the weapon, and I thought they'd be comfortable, their edges tends to stick out and dig into my hands. They also bulk up handle in a way that my hand just doesn't easily fit it. Like, I know my Oodassault's handle is also rather big, but my hand still fit around it naturally with a flat back and indents around around my thumb and point finger web. But this is something I can customize in the future, so it's not the end of the world by any means. I can still use it as is without being in total pain.  The trigger is a bit different. Not uncomfortable, but not the way I like triggers. Something I'll want to change, but I don't want to compromise its strength, so I'm going to keep analyzing it. The stock is a bit compact. This is yet another preference thing, but I'd like it at a slightly longer length. The charging handle isn't too comfortable to use either. With the rear sight integrated into it, it's a bit difficult to get a good grip on, which is important when you have the bands loaded up on it.  And again, this is subjective so I'm sure I can improve it for my preferences and it'll be just fine. I otherwise appreciate what Killerk attempted here. The front grip on the other had is rather comfortable. I don't think I'll need to change that ever. Ease of Use: B Things look up from here. The ratchet mechanism wasn't immediately obvious to me, but with previous K'nexing experience, I figured it out. Still, I wouldn't trust a newbie to be able to pick it up and know how to use that part specifically without direction. So that's part of the reason it's not a higher grade, but again, nitpicking. It's otherwise incredibly useful to be able to wind the band without turning the turret itself. It lets you load ammo and then just twist the ratchet, which isn't too difficult, to make sure it loads after each shot.  When I change the charging handle to be more comfortable, I'll appreciate it much more. Having a charging handle on a weapon loaded up with a lot bands makes it a lot easier to use. The rail guides and the pin guide are all perfectly constructed to make sure it's a smooth, straight pullback.  On that note, back to the stock from an ease of use perspective, because it's a bit shorter than I'd like, I don't feel like I have proper leverage on the charging handle. It's one thing I like about pistols, being able to use both arms to pull apart the gun and the pin to make it easier to draw. For this weapon, it's recommended to shoulder the stock and push back against you, which would be a little easier for me with a longer stock. It probably won't be a problem for others. Overall, I think someone strong enough could pick it up and, with a little direction, figure it out pretty quickly. It's something I could easily teach a friend how to use and then they shouldn't have a problem with it. Reliability: A This is one of the areas where the TR shines. It's only not perfect because of a few possible things you can do to mess it up. Now, to be fair, I haven't fired it enough to have a misfire, but I doubt that'll ever be a problem. The nature of the turret itself means that you shouldn't have any problems. However, I'd worry about little things like bumping the turret in such a way it skips a round. The power transfer pins offer a point of failure for the gun if you're not careful. Removing a round requires you to manually push back in the pin to avoid accidentally firing off an empty chamber, which I can imagine might be bad. I'm also a wee bit skeptical about the trigger setup but it hasn't failed on me. I may want to make a safety mechanism for this weapon, though. Something that wouldn't allow the trigger to move out of the way of the pin at all. Construction: A-  It's pretty dang solid. I did notice (more nitpicking) that the handle connection creaks a little bit. So it's not perfectly solid, but Killerk did a pretty good job at constructing this in such a way there shouldn't be many points of failure. It held up in shipping after all. There are some odd support structures here and there, but then some areas that are either neglected, or he just didn't care about. Honestly, I have no idea what he added because he thought it was necessary, what he added because it looked cool, and what he added just because he could. So there are some things I might change for the sake of consistency and aesthetics, but it's otherwise something I'd trust be able to drop, pickup, and use just fine. I'd only worry about dropping it right on the turret.  Performance: A+ This is the one area you can say is perfect for the TR. Basically, it's designed to maximize power, and finned ammo are designed to be stable, thus increasing range and accuracy. The tube barrel minimizes the snag on the pin from hitting any gaps and gives the gun a solid mounting point for bands. The turret treats each round as a single shot. The length of the charging distance is maximized while still being practical. It's as good as you can do for a pin gun, and it's as accurate as you can make K'nex ammo with minimal modification/using entirely different materials.  Overall Thoughts as a War Weapon:  I'm not going to grade this because there's so much opinion thrown in here, it wouldn't be fair. I can see where this thing would be everyone's weapon of choice. It has an 8 round capacity, which seems limiting, but you can reload whenever you happen to find ammo, so in theory it shouldn't be a problem until you're rushed with low ammo. If fin ammo is allowed, then clearly it's the best you can do for a repeater at the moment. Without it, it's got the most effective range you'll possibly find for a pin gun, though it's just not as easy for me to prime as a pistol. It's a weapon more about picking your shots instead of dishing them out as fast as possible. I'll need to do some raw comparisons with my Oodassault pistol to see which I'd prefer after I see all the differences. For example, what if the range really does make a difference compared to the ease of recharging? I'll just have to make it to a war with both weapons sometime and see which I do better with. Overall Thoughts as a Fun Weapon: Its main novelty is the range and accuracy you get in a repeater. It's satisfying to shoot multiple rounds down range and hit your target with ease. Other than that, it's mostly featureless. It's not something I'd dink around with in the house (mostly out of fret of damaging the walls). It might impress my friends the first time they see it and how far it fires. The ratchet mechanism might also be cool to show. But after that, there isn't much wow factor. Not that you'd need much more. It shoots hard. That's all you'll need to wow someone with plastic and rubber bands. I'm personally the kind of guy that likes having things like realistic charging handles, removable magazines, adjustable stocks, etc. just for novelty's sake, but that's just me. This is a no-nonsense weapon built for performance, and in that regard it does very well. I'll keep mine around and make small modifications to it. I won't deconstruct it for pieces to make other weapons. It'll be nice to have a raw performance weapon around all the time so I can focus on new concepts without think "I wish I had something that fired well, I'm going to rebuild my Oodassault." So it's fun enough to be worth keeping.  Overall, I'd highly recommend making it at least once just to experience it, see what it's all about. If you enjoy performance, taking highly accurate and ranged shots at targets, you'll appreciate it. It's also pretty modular in that if you keep its base construction intact, you can personalize it reasonably well. Better weapons can be built just for the sake of having fun, so it's not something everyone might want to keep permanently, but if you have the pieces, I think a lot of people will like to keep it around, as many already have.

Can you check this design? Answered

On Aug 26 I posted an ask about a design of a new type of motor.  I received some good advices. Redesigned 02/10/12 The previous design had a major flaw, that went unnoticed at first but it became clear as I went into the construction of the prototype: the thermal barrier would be totally useless, because the steam produced in the boiler necessarily have to go through liquid water to make its way into the compression chamber. This would have two disabling consequences: 1) the vapor would cool quickly, 2) the water would heat up quickly, too. Since any heat engine operation is based on temperature differences, this failure is vital. The new design does not have that problem. The water falls directly into the hot boiler, a small amount at a time, with the piston in the upper dead point, or below (note that my drawing is reversed with respect to what would be a conventional combustion engine). The water is kept cold by being stored in a separate reservoir, attached to the motor body only by the inlet and outlet pipes. Water injection is performed by momentarily opening a valve at the appropriate time. Since the interior of the water reservoir accumulates pressure as the engine works, this pressure would be in principle the responsible to force the output water through the tap. If that's not enough, I could add a little manual compression pump to initially load the reservoir with compressed air. So once the Primus heaters worked, which were extremely useful for decades. The exact moment, quantity and duration of water injection should be adjustable during operation of the engine, to find the optimum point for these parameters. These mechanisms have not thought of yet, but they can not be too complicated. As regards the boiler, it is likely that one heated surface be insufficient to rapidly vaporize the water, since in these conditions it usually adopt a globular shape that greatly retards heat transfer (Leidenfrost effect, http://resnickscity.wordpress .com/2011/01/page/3 /, http://es.wikipedia.org/wiki/Efecto_Leidenfrost, http://en.wikipedia.org/wiki/Leidenfrost_effect). I think that could be solved relatively easily by a double bottom to the boiler, in order to "force" the water into laminar contact with the hot surface. If this is insufficient, it would still be possible to inject the water by pressure between two heated surfaces. I have to also investigate the possibility of to make "super hydrophilic" the surface of the boiler. Regarding the compression chamber, this design makes it much longer, thus establishing a better differentiation between the bottom hot and top cold. But the main novelty is that the displacer stops acting on a small amount of water to turn acting, as in the Stirling engine, on the entire volume of the steam in the compression chamber. By forcing the steam to move towards the cold zone it produces its condensation, thereby changing the pressure by decompression, and so completing the cycle of the engine. The condensation water adheres to the cold walls of the chamber, then it slides down by gravity, and is intercepted midway by the retaining ring, which leads it back to the water reservoir through a single action valve, spring driven. I guess that to pass the water to the reservoir will be enough the vapor pressure that occurs in each cycle. The accompanying drawings are quite precarious, but only pretend to give a general idea of the design. Please ask me if you want more details ------------------------------------------------------------------- Nuevo diseño 02/10/12 El diseño anterior tenía una falla importante, que me pasó desapercibida al principio pero se hizo evidente a medida que avanzaba en la construcción del prototipo: la barrera térmica iba a resultar totalmente inútil, dado que el vapor producido dentro de la calderita tendría que atravesar forzosamente el agua líquida para abrirse camino hacia la cámara de compresión. Esto tendría dos consecuencias inhabilitantes: 1) el vapor se enfriaría rápidamente; 2) el agua se calentaría también rápidamente. Dado que el funcionamiento de cualquier máquina térmica se basa en las diferencias de temperatura, esta falla resultaba vital. El nuevo diseño no tiene ese problema. El agua cae directamente dentro de la caldera caliente, una pequeña cantidad por vez, estando el pistón en el punto muerto superior, o sea abajo (ojo, que mi dibujo está al revés respecto de lo que sería el de un motor a explosión convencional). El agua se mantiene fría, por estar guardada en un reservorio separado del motor, unido a él solo por los caños de entrada y salida. La inyección de agua se realiza mediante la apertura momentánea de un grifo en el momento oportuno. Dado que el interior del reservorio de agua acumula presión al funcionar el motor, esta presión sería en principio la encargada de impulsar la salida del agua a través del grifo. Si esto no fuera suficiente, habría que agregar una pequeña bomba manual de compresión para cargar inicialmente de aire comprimido el reservorio. Así funcionaban antiguamente los calentadores Primus, que fueron sumamente útiles durante décadas. El momento exacto, la cantidad y la duración de la inyección de agua deben ser regulables durante el funcionamiento del motor, para hallar el punto óptimo de esos parámetros. Esos mecanismos no lo he pensado todavía, pero no pueden ser demasiado complicados. Respecto de la caldera, es muy probable que una sola superficie recalentada sea insuficiente para vaporizar rápidamente el agua, dado que en esas condiciones esta suele adoptar una forma globular que retarda mucho la transferencia de calor (efecto Leidenfrost, http://resnickscity.wordpress.com/2011/01/page/3/, http://es.wikipedia.org/wiki/Efecto_Leidenfrost, http://en.wikipedia.org/wiki/Leidenfrost_effect). Creo que eso podría solucionarse con relativa facilidad haciendo un doble fondo a la caldera, de manera de "obligar" al agua a establecer contacto laminar con la superficie caliente. Si esto fuera insuficiente, siempre quedaría la posibilidad de inyectar el agua a presión entre ambas superficies recalentadas. Tengo que investigar también la posibilidad de hacer "súper hidrófila" la superficie de la caldera. Respecto a la cámara de compresión, este diseño la hace mucho más larga, estableciendo así una mejor diferenciación entre la zona inferior, caliente, y la superior, fría. Pero la principal novedad es que el desplazador deja de actuar sobre una pequeña cantidad de agua para pasar a hacerlo, como en el motor de Stirling, sobre el volumen completo del vapor contenido en la cámara de compresión. Al obligar a este a desplazarse hacia la zona fría produce su condensación, cambiando así la presión por descompresión, y completando así el ciclo del motor. El agua de condensación se adhiere a las paredes frías de la cámara, resbala luego por gravedad hacia abajo, y es interceptada a mitad de camino por el anillo de retención, que la conduce nuevamente hacia el reservorio de agua a través de una válvula de simple acción, a resorte. Supongo que para hacer pasar el agua al reservorio será suficiente con la presión de vapor que se produce en cada ciclo. Los dibujos adjuntos son algo precarios, pero no pretenden más que dar una idea general del diseño. Por favor, pregúntenme si quieren más detalles.
