Just a Thought

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.

Looking for thoughts.

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.

some thoughts

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

Fun (Techie) Question(s)...(will be continued if there is interest) This is #1:

Engineering problem: The problem is to take an extension cord (you will have to figure the gauge at some point), and wire in 2 more "sockets" (for plugs) in series or in parallel, plus 3 neon bulbs in such a way that they only light when something is...#1: plugged into the corresponding socket &#2: the something (appliance, light, etc) is turned on, in other words, when that portion of the circuit is closed. The cord will be for very light rated appliances or bulbs. Nothing beyond a kilowatt althogether. Specify extension cord wire gauge and anything else needed for the project and it's necessary rating / part number. And most of all, have fun....and don't over think the problem ;-) OK, I blew it.....I knew I had created a similar cord to the one I described, and finally found it....only it doesn't do what I said it does. I merely had Neons that come on when the cord is plugged in.......this is what happens to your memory as you get older LOL.

Thoughtcrime 2.0

The BBC says 2007 was a big year for bloggers being imprisoned. Worldwide there were 36 confirmed cases of people being arrested for blogging and certain organizations suspect, but cannot verify, that hundreds of more people were."The report predicted that the number of blogger arrests in 2008 would exceed the 36 seen in 2007 thanks to greater popularity of blogging as a medium, greater enforcement of net restrictions, and elections in China, Pakistan, Iran and the US."

Excessive Conservation Wearing Out [noun]...

So... While brushing my teeth - I first rinse my brush, turn the faucet on, brush, then rinse the sink/mouth. Yes, I turn the faucet off while brushing. And if you're counting - that's two on/off cycles per brushing...I've been playing with this tool: http://www1.eere.energy.gov/femp/procurement/eep_faucets_showerheads_calc.htmlAnd I pose an open question for discussion.. But first, my data/research...I'm estimating 3 minutes of use per day - 365 days/year. According to the tool... I use 2190 gallons per year. Lets say that's 5 uses per day (2 for teeth - 1 for bathroom use). The tool seems to estimate an 8.4 year service life - so that's a total of 18396 gallons of water over it's life as a faucet.So If I leave the water on while brushing - that's 3 on/off cycles per day.butIf I turn the water off while brushing - That's 5 on/off cycles per day (40% more cycles).Realistically, a faucet's wear comes from on/off cycles - each use bringing it closer to retirement. So 40% of 8.4 years is 3.4 years.Now... Leaving the faucet on an extra 4 minutes per day (2 minutes per brushing) consumes 2920 gallons of water per year.The difference over 8.4 years is: 30660-18396=12264 gallons. At about $4 per 1000 gallons - that difference is $49.06. BUT, the direct replacement for my faucet (as priced today in home depot to the exact model) is $75. So after 8.4 yearsFaucet remaining on will cost me:$49.06 + $75 = $124.06Faucet being turned off will cost me:$75 + $30(prorated cost of faucet for 3.4 years of wear on a new faucet) = $105Differences:$19.0612,264 gallons of waterThat is to say - due to extra wear on my faucet - it's only marginally more economical to turn my faucet off while brushing my teeth. If I wasn't me, and not able to DIY replace - it very well may be cost effective to leave it on given the cost of a hiring a handy man or plumber...Okay... Now that you've read the above... please discuss your thoughts. I am very much aware of the assumptions I have made (no need to point them out) - just looking for opinions :)UpdateLets turn this discussion on it's head now... As several have pointed out, conserving is more important - bonus as it's close to an economical wash in my fictitious scenario above (it's not 100% real and based on data from the link above and some hefty assumptions).My car uses .3 gallons of gasoline per hour at idle. Lets take a 100% city drive in heavy traffic (my drive yesterday). I was at a complete stop due to traffic lights or traffic for 20 seconds or more a total of 12 times to travel ~10 miles (yes, I freakin timed it). So that's a total of 4 minutes (wow, that worked out nice) of idle time. That time consumes 0.02 gallons of fuel costing me $0.06. If I were to make that commute 5 days a week, twice daily - that's a cost of:10.4 gallons of gasoline$31.2 worth of fuelSo, a new starter for my car costs $130. Typically the motors don't actually die - just the contacts. But lets assume I don't want to fiddle with that and just want to direct replace (corollary to valve washers :D).This means - using my starter an additional 24 times per day - it will take 4.2 years for the fuel savings to pay for a new starter. In 4.2 years - averaging 12,000 miles per year - I will have traveled 50400 miles.Okay - now lets consider the cost of fuel to restart - 24 times.... According to mechanical engineering magazine, a V6 engine used 5 seconds worth of idling gasoline to restart. So - redoing some math to compensate - that's a savings of7.8 gallons of gasoline per year$23.4 per yearTime to recoup 1 starter: 5.6 years (equating to 66000 miles)So, I'm having some problems finding data on starter life cycle - all I have is anecdotal evidence... *My personal car has 115K miles and is ~8 years old - and I've been doing this since I bought the car >2 years ago. *My last car was sold at 98K miles and this was done for a little less than 2 years (the car was 8/9 years old when sold).*My first car had unknown mileage (estimated around 150K), was 10 years old and the engine was killed at stoplights.*My parents own a conversion van (seldom used now) that is 12 years old, 120K miles - did not shut the engine (v8) down at traffic lights.None of the cars above have had their starter go.*Father had a truck that had it's starter replaced around 220K miles - unknown age. That car left us with a blown connecting rod around 300K milesBatteries... Yes, this does put more strain on your battery... I'll go more into that when I can find some better data (more than anecdotal :p)...But, that's to say... It's economically viable to turn off your engine at traffic lights... So much so, it's illegal to idle (over a certain period of time) at traffic lights in some countries...

With current computers, it depends on your definition of "getting a virus" If getting a virus means infected and damaged by it, than no. If it means carrying that virus, yes. This is of course, assuming "you" is a human  or other biological organism. If the "you" in questions is a sentient computer or AI, than the computer would get the virus because the "you" sneezed a virtual virus. Then of course, you can go into the combination of the above examples, like a biological, sentient computer or robot that looks like a human. Wait, wouldn't that be a human?

K'nex Sniper thoughts?

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. Oh and maybe a heartbeat sensor for all the MW2 fans out there XD -Lowney

Thoughts on modifying a mower to a dethatcher?

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.

Thoughts on painting a toilet seat?

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 : ).

Anyways, there are a few instructables on loft beds and I plan on making one that will be much more functional and better (not that the ones on here are bad) my question is, should I make it an instructable? it will have more features to it, like a shelving unit built in and a built in loft night table. but basically it will be very similar to others. what do you think?

Your thoughts on an inkjet hack

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.

An idle thought on career diversification.

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...

Laser Sonic Screwdriver - Thoughts?

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?

Failed Experimentation : AI : My new creature is alive !

.It's alive !Alive, yes, but not as much intelligent than expected ..........Instead of watching a stupid movie at TV, I decided to write a tiny AI programme all in PHP.My goal was to get some functionalities comparable to logic programming languages like Prolog.In simpler words : I wanted to create a programme that could learn facts, and find the solutions to some logical problems.For instance :> blue is colour.Okay.> carrot is vegetable.Okay.> blue is colour ?Yes.> blue is vegetable ?No.> carrot is colour ?No.etc.So far, I can teach it facts in the form of 3-words-affirmations, and I can ask it questions and definitions, and the creature is able to find some connections between facts.Experimentation #1 : > red is colour.Okay> black is colour.Okay> orange is colour.Okay> orange is fruit.Okay(Here, we have a trap : orange is both a color and a fruit.)> red is colour ?Yes> black is fruit ?No> orange is colour ?Yes> orange is fruit ?Yes(Good. The beast did not fall in the trap.)> translate : red- "colour"> translate : orange- "colour"- "fruit"> translate : colour- "red"- "black"- "orange"Good ! The beast can give a sense to the words it learned.Experimentation #2 :> Paul is human.Okay> human eat fruit.Okay> apple is fruit.Okay> human is animal.Okay> animal eat meat.Okay> animal is mortal.OkayNow, let's see if it can "chain" the facts in a logical manner :> translate : Paul- "human"Here it should have replied : "human", "animal" and "mortal", since human are animals, and animals are mortal ...Let's see how it defines "Paul" :> define : Paul- Paul is humanMy creature seems obviously narrow minded ...Let's quiz it now :> Paul is apple ?No> Paul is fruit ?No> Paul is human ?Yes> human is Paul ?Yes> Paul is Paul ?Yes> Paul eat fruit ?Yes> Paul eat apple ?Yes> Paul is animal ?Yes> Paul eat meat ?No> Paul is mortal ?YesAs we can see, it successfully (and surprisingly) replied correctly to each question by connecting facts together, excepted for "Paul eat meat ?".At this question, it should have replied "yes", since it knows that "Paul is human", "human is animal" and "animal eat meat". But it did not ... ... and it's bizarre since it can reply correctly to "Paul is mortal ?", from "Paul is human", "human is animal" and "animal is mortal", or to "Paul eat apple ?" from "Paul is human", " human eat fruit" and "apple is fruit" ...Interesting, isn't it ? =o)If you want, you can submit your facts and questions to my experimental creature (which has no name yet) =o)What would be interesting also, is to confront it to a "paradox" just to see how it behaves ! =o)20080625 : For those of you who would like to have a look at the guts of the beast, here is available the source code.However, keep it mind it's a spaghetti-code and many function names are in french (as well as comments).Also, this version relies on MySQL to store and query facts (I'm planning to replace it with simple arrays though), which make the code slightly more complicated than required ...The main code makes less than 250 lines =o)There is no direct input interface : instead, it use scripts (exp_*.php) that call functions. For example :declarer("red","is","colour"); // <---- declarationsdeclarer("black","is","colour");declarer("orange","is","colour");declarer("orange","is","fruit");verifier("red","is","colour"); // <---- questionsverifier("black","is","fruit");verifier("orange","is","colour");verifier("orange","is","fruit");... which is slightly more complicated than what I showed above for the sake of comprehension and simplification !

I love the new home page but if you could add text to the pictures that would be cool. I do want to thank people who created and designed the homepage for putting it here, I know it was a lot of hard work. (P.s. I'm running firefox 4.0 on Mac)

Anyone got thoughts on this instructable idea?

I own a foodsaver with those airtight containers. The rubber piece came off the other day and got me to thinking. Almost any container could be used by drilling a hole in it. Maybe someone could come up with a DIY to make containers that work with foodsaver or those Zip pumps that take the air out of containers. Those pint containers that come with Chinese food might work. Or Tupperware or Ziploc containers would do also. I just have the idea but not the talent to do it. I'll leave that to others. ha ha.

thoughts on a project i am toying with

Hey guys...little project I am working on, very very beta. But I have an led sign displaying my Instructables stats (instructable coming soon) and while building it, I realized that Instructables didn't have an API of any kind to see our stats all together. So I rolled my own...check it out http://irssistible.appspot.com/ click the pie chart on the result page to get the url for a xml output...very, very beta, but you can fetch the data via python or processing via the xml url data, or parse the results page. It's buggy, but it is sorta working.

More thoughts on Video-Only Instructables

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.

Staying motivated to complete a projects . . thoughts?

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. Let's have a conversation!

peculiar issue with arduino clones; thoughts?

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?

Thoughts on Arduino/Raspberry Pi Idea?

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? In addition, here is a 1-minute survey (on a similar subject) if you are interested: Survey: https://docs.google.com/forms/d/1dkwyhC59I7h8IOuNFyL_tbjo7AFucTP0KQS0mYH1qy4/viewform
