Not long ago....

Not all that long ago, I went there to get a Heat Gun, glass cutter wheel, glass drill bit and pay about $30 for the whole lot, according to their ad.....BUT when I got there, the Heat gun I wanted was on an even better sale so I got the whole lot of tools for what I expected to pay for just the heat gun; about  $20

Long time no talk

Hey guys, or whoever is reading this and even slightly cares.  I haven't made a gun in a really long time, and I haven't really responded to the last 300-400 comments.  Now that it's the holiday break, I'm going to have a lot more spare time.  So this is what I feel like doing, making a new gun.  I want your ideas for it, because I'm really not that creative..  So what do you guys want me to make? Also add me on Xbox Live; TH3 BR0WN B0Y.  The "0's" are zeros.

Been a long time...

I'm back.  I've got some projects that I'd like to post but it's going to take a while to do so.  It's hard to take good pics of a tiny crochet hook, thick thread, and the minute stitches that you just created!  I think I'll just take pictures of the bigger version, the stitches are the same either way.  As for the other project, I think I bit off more than I could chew so I need a new approach or to actually come up with the math equation for something I just wing without thinking...  Lots of problems to solve!

Long Time No See.

Okay to start this off I'll begin on telling you how close i was to quitting "k'nex", so anyways when I almost quit "k'nex" i got into war games, like Call Of Duty and Battlefield Bad Company, mostly B.B.C though, so as i collected more guns thought B.B.C I thought to myself, I should keep my k'nex and build some replicas, but then again i thought psssht I'm not any good at building guns, so what I want you people of Instructables to do is to find me the best of the best replicas for me to build, and thank you in advance.

Long Range Hybrid Crossbow

HERE IT IS. The Brickster LDS is a hybrid crossbow. It doesn't have a bow. It has a range of 250 to 300 feet with 16 to 32 rubber bands. It is extremely strong and could hold about 80lbs of force. The arrows are smaller than an average crossbow arrow so they fly slightly faster. It has no track so it is a slingshot type crossbow. Will be posted in a month or 2. Amazingly powerful. Has over 800 pieces and a Ballista attachment that rolls and keeps it at a 30 degree agle with the ground. Low piece and a great gun, If only I could show you. . . . . . . . . . . WAIT, I CAN!!!!!!!!!!

So long cruel world!

Well I wasn't that active in making guns, but I think I should move on to bigger things. I will still lurk around instructables, however you wont see me doing knex guns unless I have an ingenious new idea that I'm sure I can portray correctly. I will probably be making instructables pertaining to: Art, Guitar, Video games, and other things, that is all goodbye and goodnight! P.S: 5th pic is an experimental curved mag I was developing around a year ago to go on my mp7, anyone is welcome to use it as long as they give me proper credit and link me to the instructable/slideshow.

One that makes use of one of the old sattelite tv dishes sitting in the garage. Requesting advice, comrades.

How long with this power a led

I have an idea for a nightlight for kids or even adults in the hallway or something.  But I am running into a problem.  The main housing for this light is going to be pretty small.  I was first planing on running this off a household electrical plug and that would work best.  But I would not know quite how to step down the power from the wall to only run 2-3 led lights.  I am sure I could get some sort of small circuit board that would drop the current.  However because of the small housing I doubt I could fit that in there.  I know I am not giving a whole lot of details but I do not want to give away my idea quite yet.  What I am wondering is how long would say 1 AA battery run 3 LED lights?  I am thinking this idea is not going to work out because people are not going to want to have to replace there battery every week or even more.  So if anyone has some input on this idea then please let me know.  The housing I think I would have to work with would be something like a pipe that is maybe 1 inch across the opening by about 2 -3 inches long.  So nut much room to work with at all. I await your replies.

Long Range IR Transmitter

I'm trying to build a guidance system for RC airplanes and drones. This should work by sending different IR signals to different locations in the air, so the drone will pick up signals specific to one location, enabling it to know where it is. (Like a mini, simplistic VOR, if you know about aviation) I'll probably use an Arduino on the ground with the transmitter, and a Raspberry pi onboard the airplane. I would like the IR signals to reach as far as possible, so does any one know of any small, high power IR LEDs? Also, if you have a good idea on how the signals could be accurately focused, so they line up next to each other without over lapping, let me know.Thanks!

The Coronet Midget - 'Not as long as a cigarette'

The last few weeks I've been helping my colleague sell some items before he retires. Yesterday he gave me this as a thank you.This tiny film camera is from the 1930's, its a great example of early plastics (Bakelite). At the time they came in 7 different colours, its just like the iPod all over again! You can see how small the item is from the photographs (usb/penny to show size).The main sales line for the camera was,Its not as long as a cigarette Which at the time was the main pocket sized item you would compare something to.The camera itself took a 16mm photographic paper, and its lens could focus from anything from 5ft - infinity. Included in the images is one of the original leaflets selling the camera in the US (points to whom can pick out the physical impossability).Also included is a PDF of the original manual that I found images for on the internet then cleaned up and pushed through quark.Now, you might be asking yourself, what is gmjhowe going to do with it? Well, I intend to use it as its meant to be used. So Ive ordered myself some 120 camera paper (which can be cut down to the 16mm paper I need.) along with some chemicals.No doubt I will put up an instructable for it! My aim is to carry it around everywhere, so as to catch that artistic photo. Of course I will make it a nice little leather case to protect it, the item itself is valued at about £70!Anyone got any suggestions? Or, is anyone else into B&W; photography and want to share there thought/advice?

Navigating large-response topics

As a participant in AngryRedHead's Photo challenge, I've noticed that, as the thread gets longer, navigating it to find my past comments and replies is getting... odd. Using the next and previous buttons seems mixed up.  Sometimes you don't get a new set of comments, sometimes you get a few extra comments in between the ones you already saw, sometimes nothing happens. Similar things happen on other topics with large numbers of responses. (Running XP and up-to-date FireFox)

Short-term vs. Long-term

My tests got me thinking, since I want to go gaming on Garry's Mod so bad, but then my coalition of brainwaves composed of rational thoughts and my conscience told me that I can achieve my short-term goals (gaming) in conjunction with my long-term goals (owning my classmates in the tests then gaming afterwards) if I achieve certain short-term goals (studying) that would require focus, determination, and moral (can't study when you're depressed). The reason why I posted this here in Instructables is because I wanted to know your opinions about short-term and long-term objectives. Like, which is better, short-term or long-term missions? You would get me if you're in my situation, sitting in front of the computer, worrying about the tests, but then you wanna go gaming. Once I get enough data, I can post an I'ble about my conclusion. Here's what to post: -your thoughts about short-term vs. long-term -opinions -thoughts that pop up in your mind all of a sudden What not to post: -spam -questions not pertaining to the topic at hand -advertising your instructables -posts that only flamers and trollers post -talking about how awesome GMod is (that's the abbreviation gamers gave to it) Also: I don't care how long your post is, as long as it's in the to-post list, it's good to go.

How long is a Flying V guitar?

If anyone happens to have a Flying V guitar/bass, how long is the body from the very bottom of one of the "wings" to where it meets the neck? I'm going to build an electric bass, and I have all the dimensions except for that.

How long is a gift code valid for?

My first ever instructable got featured.. then the next day it was placed on the front page. I'm really stoked about this, plus it won me a 3 month and a 12 month pro membership. Awesome! How long are the gift codes valid though? Will they remain valid forever or do they need to be used within a certain period? And can I donate a code to a friend?  Cheers, -Aku.

How long will the discount code work for?

How long can you use the discount code for? I have a big wishlist I'm planning on buying in may (utilizing birthday money), and if I don't win the contest, I would like to know if I can still wait until may to buy the stuff. EDIT: I was under the assumption that the "add a new topic" button would add a new topic to the contest, not just the forums. I was talking about the april fools day contest.

WOW its been a long time...

Alright, I know its been a long time and there are probably a lot of things posted on my ibles that i haven't answered. If thats the case then just ask anything you want on this forum and I'll get to answering it. Because it has been such a long time i was kind of expecting to see some great new stuff out there, but I have to say, I'm not very impressed. Sure there are some good guns that came out, a couple bolt actions and bullpups that were impressive, but other than that, theres not much new. We aren't ging to get anywhere unless we start coming up with new ideas and sharing those ideas so that others can make them better. That said, I'm glad to be back and look forward to building with you. -Kinetic

Is there a way to estimate how long an antenna is?

If I built a radio transmitter and then attached it to an antenna of unknown length, is there a way to calculate the length of it using transmissions? Or, as a separate question, if I had an antenna of known length and then increased or decreased the length, would there be a way to estimate the new length from transmission properties (basically without physically measuring the antenna? Assume the antenna is a straight line.
