Hello everyone, I'd like to share a thought that occurred to me. It appears to me that there are really only 3 main qualities of a knex gun: -Range -Fire rate -Ease of use Now out of these three we have already maxed out range with slingshots and the NAR. Now we need to work on maxing out the other two through semi autos and such and we will have truly revolutionary weapons. Then we can start combining multiple elements and creating easy to use semi-auto slingshots and such. I just wanted to share these thoughts with the community.

My PC wnt a bit wonky this morning. Mouse pointer moved around just fine but the system wouldn't recognize any clicks. Well at first i could click on the web browser and open a new tab but that was it. I restarted the system and had the same problem. So i wasn't able to lick to log in. So i tried another mouse and got the same result. Then i tried both mice on different USB connection both on the front and rear of the system. No change. Out of frustration i slammed the mouse down on the keyboard tray a couple of time and then everything started working fine again. Any thoughts on what happened? I suspect it's an issue with the keyboard. Being a wireless keyboard that came with a wireless mouse i think the keyboard had something to do with it. I've had an occasion where the keys stopped working on the keyboard till i moved the receiver around a bit. oh well.

A couple quick observations from a web dev which i hope can be of use to you as i love your site: considering the state of the world economy, actually the general state of the world, and the recent interest in gardening, i think that agriculture, or gardening, or growing food, or whatever you want to call it should be one of the main topics in the top nav. right now it sits uncomfortably between 'food' & 'life'. the help-> feedback was difficult for me to find because i did not equate feedback with help, i think 'feedback' should be in the left pulldown along with forums, marketplace, and help, and then you could even break it down into different feedback categories. the google ads are styled exactly like the rest and are right up the top before everything else. they got me the first time, and that's all well and good, as you deserve the $$. maybe it's too aggressive though, and may annoy people, even if subconsciously over the long term. maybe just reducing their font-size and arranging them horizontally would strike a good balance? best, _c

I'm drawing up some mental plans for a Sniper rifle. I posted some non-gun k'nex projects but they were never as popular as weaponry. I know there's a tonne of K'nex snipers out there already, but most of them underneath the body are just a basic gun with a blue rod mag, and a lot of the time the mag isn't actually removable. Of course there's nothing wrong with this, I myself have made guns with this setup. However, for my new Sniper, I want a removable mag with lesser-used ammo. I was thinking either orange-connector+grey connector ammo or yellow rods. Basically I wanted to see what the community wants the most, aside from Oodammo, because that's a tad awkward! Also any suggestions as to what else I should add to my Sniper? I was thinking: Removable Mag, breach loading single shot chamber, rails (like ironman's), detachable scope and Bipod, rear monopod, true trigger (of course), pin guides and maybe a section where a small pistol can fit, probably TheDunkis' flat pistol or r3con's (spelling?) mod for it.

Question by Jumpin Jehosaphat 8 years ago | last reply 8 years ago
Briefly, my lawn is a mess and I cannot afford either an electric rake or dethatcher. I have tried using a spring-tined rake to dethatch the lawn but it is too labour-intensive - and I have around 250m2 to cover - not for the faint-hearted! However, I do have a petrol rotary lawn mower and a spare blade. I have thought of combining the spring-tined rake to the blade to dethatch that way. I don't mind the thatch not being collected - as I expect it will leave the mess on the floor - I can simply dethatch at a higher blade height and then cut/pick up the mess on a lower blade setting. I don't have a welding machine, nor access to one. So I wondered if the good people here might lend me their brain cells to consider (a) what I might use as a rake on the blade and (b) how to secure it on to the blade. I have seen one of those rakes which can be spread at will and I thought to size it and secure it with a metal band and rivets - and then rivet the whole thing to the blade. What do you think? I had also thought that I could fix the rake on the opposite side of the blade. The blade is not reversable/obversable - there is a one-way key that oreints the blade to one position only. Please do not trouble yourselves with warnings about safety etc as I think I am aware enough to consider this for myself - unless it is to say "don't do it". I also know about having to balance the blade weight. As ever, thanks for reading me and thanks for your time to reply.

Hey folks! I wanted to tap the collective mind of the Instructables community on this one: We recently did a radical redecoration of our bathroom. One of the only things that wasn't touched so far was the toilet. Rather than getting a new (probably boring) toilet seat- I'd like to try painting the old one (I'm talking about the SEAT here, not the cover). Is it feasible for a long-term part of the bathroom, do you think? I've never really painted anything like this before- what paints / techniques would folks recommend? I was thinking of sanding down the surface, applying a rust-colored enamel (with some black patterns), and then a goodly amount of clear coating. Appreciate any thoughts (even if they are "Hey, that won't work- suck it up and sit on a boring seat like the rest of us"). Obviously any work will be documented and submitted to the site : ).

I've been mulling around a cheap (as in free) way to make a 3d printer, or laser engraver. I'm looking for flaws in this plan: 1)Find an inkjet printer thrown away because new ink would cost almost as much as a new printer. 2)Mod the paper feed motor assembly so that the it moves the top half of the printer along a rail instead of moving paper. 3)Short out the pins to ink colors other than black to give a false "full ink" value. 4)Attach a power transistor to a cutting laser circuit, and the black ink pins. The idea is that if I sent a black and white image to the printer, this could perforate or even cut a suitable material. I already have a few areas I'm concerned with, but I'd like a second or third opinion on possible trouble areas.

As you may know, I teach Science.You may have noticed that I occasionally venture an opinion on science-related topics.You may also have noticed that bad science, and the acceptance of anti-science tend to get on my nerves.Part of the problem, of course, is the meeja - the majority of journalists have little or no science training, so they focus on the dramatic sound-bites when reporting stuff. Heck, these days the majority of journalists aren't even journalists - they're bloggers.After the massive fuss I had to put up with at school over the LHC (destroying the world by sucking it into an exploding black hole then turning time backwards), I tried to find out where the kids got their panicky ideas from, and it turned out to be the tabloid press (the Star and the Sun, for UK readers).Now, I could wait until the papers publish their bad headlines and write an annoyed letter, or I could be pro-active.Do any of you guys think there is any mileage in setting myself up as a consulting service to the scientifically-illiterate news media?I thought, maybe, offering "expert opinions" on scientific events to newspapers that don't have scientists on staff, or maybe a translation service, turning scientific papers and press-releases into something journalists can cope with.Comments?EDITI have emailed the main local newspapers, plus the BBC.Let's see...

So, my sister is currently a senior in college, planning on being a high school English teacher next year. She's also a Doctor Who fan. She wants me to make her a laser pointer in a sonic screwdriver case, for pointing at the projector screen, white/chalkboard, loud students, Daleks, etc. The case itself I plan to buy, probably this, and then mount a blue laser diode in. Two three questions: 1) Does anyone have one of these screwdrivers, and are they big enough to put a couple AAAs in? I'd rather not have to replace button cells every week. 2) What's the best way to get a blue or violet laser diode? Blu-Ray assembly? You can get a blue-violet laser pointer for $20 off DealExtreme, but my experience with cheap laser pointers is they burn out quickly. 3) Would I need to come up with an actual driver, or would an appropriate resistor be enough? And can a blue diode be powered off two AAAs?

Hello, not that I am unable to view videos on instructables, but more and more instructables are simply a video, sometimes with two sentences, sometimes not even that. Not that I dislike video tutorials and such, but many people still have low bandwith, or (like me) can not turn on the sound all the time since it would bug other people. Also sometimes it is more usefull to read instructions, steps and technical data. Plus there might be deaf people interested in some project but unable to understand all steps due to the fact some videos will depend on audio explanation only. My two cents: Include a minimum text length check for instructables. Video only should be youtube or such, not Instructables.

We've all been there, and I'm right there currently with a specific project:I was excited at first and started making this thing, and about midway through I've lost complete interest in the project and am struggling with motivation to finish it!For me, the contests here on Instructables were a great motivator with specific deadlines that always kept me motivated . . . but I work here now and cannot participate in them ; )When I lose interest in a project, it's often because the intriguing creative challenges have all been solved, but the project isn't yet completed. However I'm ready to move on to the next thing . . so the half-finished projects keep piling up. I've found that I'm far more interested in the active problem-solving process that "making" provides, than in actually producing completed things. It's an odd dilemma, and maybe I'm not alone in this. Do you experience this same mid-project disinterest? Aside from deadlines, what do you do to stay motivated to complete projects once the interest begins to dissipate?I'd love to hear my fellow Instructables authors' thoughts.

Hi everyone, I am part of a research group at UC Berkeley working on a product involving the Arduino/Raspberry Pi. We are conducting market tests, and would really appreciate your help answering these questions. Thank you for your time! If you use Arduino/Raspberry Pi, how often do you use it? How do you use it? Would you consider it mostly a hobby or do you use it for school/industry as well? How were you first introduced to it? What are your general thoughts on the Arduino/Raspberry Pi? Did you learn to program by using the Arduino/Raspberry Pi or did you have some prior experience? If you had prior experience, how much? What languages are you well-versed in? Would you be interested in a model-based approach to programming Arduino/Raspberry Pi functions? This would be something akin to Matlab’s Simulink or Labview’s visual programming (flowcharts). The basic idea would be to remove the need to code in C. If you are not interested, why not? If you are interested, what specific features would you enjoy? Do you believe such a tool would be an efficient way to teach/introduce students to programming?

So a little while back, I bought about 10 arduino nano clones. I'd used the nanos before, and really like the form factor, so i got some off of ebay. they worked great, and you'd know no difference in performance compared to other boards, these new ones seemed to boot faster even. unlike most, the ones i got dont use an FTDI chip, but rather a chip labeled as "CH340G". these boards were working perfectly until i was trying to test some code that was very close to the maximum size you can fit in an atmega328. it was 30,000 bytes, and mostly because of the included libraries. when i hit upload, it compiled fine, but once it got to the "uploading" phase nothing happened on the arduino board and after a while it threw an error claiming a response of 0x00, if memory serves. it didnt seem like the atmega was resetting, so i probed it with my oscilloscope, but it certainly was resetting. i thought maybe the capacitor on the reset line had issues, so i replaced it to no avail. everything seems fine in windows and i can still talk to the program previously on the chip via the serial terminal. the only way i can seem to upload code now is via the icsp header. so im wondering if anyone knows what is going on here, or how i can fix the issue?

So, I have an intex easy-set 12' pool. We have finally leveled the ground and re-filled it and it works great. I live in Texas the swim season is pretty long already. I have this all rigged up with a bungee cord tether so I can swim in place for exercise. I dug out the center to give me another foot depth where I needed it. I also have a solar cover and the entire thing is covered by an elevated parachute tent for shade/wind block. (Also modesty). For now the water warms up significantly enough by about 10 am without much heat loss at night. I have thought long an hard and this is what I have come up with to heat it during the colder months. I can build a typical solar collector with hoses and hook it to either my saltwater sand pool pump or the cheapy pool pump it came with (which would be better?) then put it on top of a metal roof piece in the yard slightly elevated from rain water, then attach radiant floor heating mats underneath it. I am hoping this would provide a boost of heat on less sunny days or when it is significantly cold, like December. With a much cheaper energy bill. I am guessing I will need to insulate the heating things a bit or something. Feel free to suggest anything. I am just kinda in plan mode atm.
Question by HidiousTak 3 years ago | last reply 2 years ago
I have had some excellent exposure from some of my projects on this site. My Nintendo card reader was published in Popular Photography magazine. My geek wallet went pretty viral. Even my shopping cart bike was picked up on Wired and may be published in an Italian magazine. These have been great because they have had my permission to publish my work. But there have been some negatives.Many splogs (spam blogs that just scrape content from valid blogs) have essentially stolen my photography. Thanks to a tip from someone near Boulder i was able to pick up a copy of a newspaper that had published one of my photos "courtesy Instructables." I'm happy to have other people take my ideas and tweak them. That's why i post my projects here. That's why the license i have chosen for all of my projects is Attribution Non-commercial Share Alike. This specifically states "This license lets others remix, tweak, and build upon your work non-commercially, as long as they credit you and license their new creations under the identical terms."So when a newspaper publishes my photo without my authorization and credits Instructables that gets me a little hot. When someone takes one of my projects and then makes a video of it and submits it to the MetaCafe rewards program that seems like a violation of my license. And when dozens of splogs pick up a popular project and i have to go around trying to get photographer credit it makes me really reconsider if sharing projects on here is actually beneficial to me at all. I'm sure others have had their great projects ripped off (if they want to retain any rights) in the effort to contribute to the community too. Admittedly, i do have a Leatherman and a few t-shirts and magazine subscriptions to show for my efforts. I do want this site to work - i truly believe in it. I guess i'd like to see image protection for projects that have specified that they need to be attributed. I'd like the license more visible on the project pages. Perhaps a "if you write about this project provide a link to Instructables.com as well as the author's website at xyz.com" type footer to projects. I suppose i can watermark all of my photos and put copyright notices all over my pages and it would be moot.
