Author Spotlight Interviews: Nominate an author!

We recently began a new round of author spotlight interviews. For the first interview, we chose to reach out and chat with Nikus, who recently won the grand prize in this year's Epilog Contest. You can check out our interview here: Author Spotlight: NikusThese interviews are a great way to learn a little more about individual contributing authors here on Instructables, and see what makes them tick! Is there someone who is an active author that you'd be interested in learning more about? Now's your chance to nominate a fellow author. There are no set requirements to be eligible to be nominated. But generally, we're looking for authors who've shared a good handful of high-quality projects, which made a notable splash within the Instructables community.And yes, if you're feeling bold, you may certainly nominate yourself! : )

Question about dumpster diving in Tennessee

Anyone know if it's legal in Tennessee? I keep calling the police but they just keep saying no instantally. Best as i can they they are assuming I'm looking to steal ID's or meth supplies (big probs with that here). I don't mind the risk of getting yelled at the the store guys but i don't want to get arrested. Also I'm not dumb enough to dig around in private dumpsters here, I'd sooner get arrested than shot to pieces LOL :P

Mouse Mouse is Missing!

Mouse Mouse was last seen on tour with us at Austin's SXSW earlier this week. He made lots of friends at Dorkbot on Saturday, but someone walked off with him while we were setting up at Sunday's PopSci party! Did he go on walkabout, join a punk band, or leave with a cute female Mouse Mouse? We hope so, but suspect he was simply abducted and can't contact us for help. If you have any information, please let us know! No kidding, I only made one1 and would really like to have him back. Drop me a note if you've got any news on his whereabouts. We'll take him back, no questions asked.1Yes, I can and will make another, but it's my art project, and therefore unique. (You may know how to make more children, but still want to keep the ones you've made.)

Test yourself for Aspergers Syndrome

Aspergers Syndrome has only been recognized since about 1995, we call ourselves Aspies. Try this test http://www.rdos.net/eng/ make sure you follow the instructions the results will only survive for an hour, so download them ASAP, the picture (a pie graph) or Aspie-Rating-Picture (ARP) and final score, you can chose to show to people, but the questions and answers are very personal, keep those to yourself. I plan to put my ARP here, that is something us Aspies enjoy displaying, something to be proud of, I hope that other Aspie group members put theirs on. Your Aspie score: 181 of 200 Your neurotypical (non-autistic) score: 28 of 200 You are very likely an Aspie It is possible to cheat to get a high score on the ARP, so I am thinking that ARPs can be voted off by members if members find the ARP unbelievable when comparing the member's ARP with said member's profile and activities on Instructables. Aspies don't practice discrimination, so even if you don't have Aspergers Syndrome, consider yourself as a honorary Aspie and sign up anyway.

Fishing the traditional way

A while ago I had a very bad day of fishing in terms of catching something for my frying pan or freezer.Same story for the old bloke sitting a few meters away from me.So we decided to pass some time with useless chats about our previous record fish we caught.While the old bloke changed bait I noticed that he did not have a hook at the end of the line.....What is that contraption and how do you catch fish with it?Old bloke laughed and said he goes hunting a lot too and always keeps the antlers from deer and such.Instead of a hook he used a round and pointy bar with a little notch slightly off the middle.Couldn't figure out how this possibly could hook a fish, so got a bigger laugh for it this time :("Make a loose fist, put it in and then pull on the line." he said and I was dumb enough to assume it would not work :(Figure it out by getting two bleeding pricks...Fish swallows the "stick" inside the bait and one there is some pull one pointy end will always get stuck.The other moves until there is no room to move anymore and the fish is spiked up for good.Only downside is that one you get a fish too big it might not grab - bad luck then LOLThis approach instead of steel hooks reminded me of the bamboo fishing poles my grandfather used to make.Be it for eel, trout, carp or even from the boat for pollock and sardine - he loved his bamboo.Even made me my fisrt fly fishing rod from a piece of bamboo :)The old guy however had more than hand made rods or horn needles as hooks.When his hands were still as good as his eyes he even made flies from these horn sticks!He explained the process to me but I never had the patience for normal flies and doing this with horn sticks and estimating how big the biggest fish might be while making sure it is neither too heavy nor fails to float...What I really liked about this otherwise wasted fishing day was the stories I got from the old man."You don't need fancy or oversensitive gear to fish, a safety pin and some packing coad do just fine if you are hungry!"Best story was how he caught a 2m gummy shark with a hand line meant to catch some sardines for bait.I could really his 3 hour struggle to get the thing on board LOLWhat are your most successfull old school or just plain weird catches with something a real sports fisherman would not even touch to cast?

Power banks and solar cells -could be great Instructable for you to make!

I was lucky to score a nice and real 8000mAh power pack with a solar cell from my local discounter.Realising the solar cell is more a gimmick than of real use I started to wonder....We all love our mobile devices and really hate that they need to be constantly charged up again.On long outdoor trips people used to carry a lot of gear and vital supplies.In todays times it almost seems that solar and battery power start to replace food and water.No trip is complete without pics, selfies and videos, some even take a drone with them.So: are there ways to increase your luggage weight by thinking smarter?Modern technology has come a long way and moves faster ever year.Solar cells are no exception here.Be it foldable setups or now even roll ups of flexible cell systems, you have the total freedom of coice.But then again: You are going on a week long camping trip in the middle of nowhere...Going on foot or using a bike means you need to keep the extras down or hire someone to carry them.Here are some of my yet to be finnished ideas:As long as you don't use them commercially feel free to make an Instructable or just use the ideas!1. Pop up amd normal tents.They seem to be the new standard now.Big with no poles on the inside and even someone who never used a tent can set them up.With the design comes a certain way of folding everything to pack it.Flexible solar cell designs won't break and can often be arranged so they would actually be able to replace parts of the outer tent material.And if it could mean they would get kinked too much and too often they are still perfect to create some "strap on panels" that can be rolled up and included with your foam underlay or mattress.A 200 or even 400W system can be transported easy and has less weight than a 80W fold up solution that you struggle to secure on your backpack or bike.2. Trackers!What is now almost a standard for fixed installations is still not seen in mobile setups.You pop up your panels, connect the power packs or batteries and go fishing, hiking or whatever.The sun moves on, the efficiency of the panels suffer.There are a lot of great Ibles for these solar trackers, from simple to 3 dimensional.Kites loves to use carbon fibre rods to reduce the weight.A tracking frame to hold a good sized flexible panel would count at less than 300 grams....In return you get up to 40% higher effiency and overall output compared to a fixed panel!Roll the panel up, fold the frame and you end up with a quite small roll that is easy to transport and very low in weight.3. Battery backups.No matter how long and well you planned, the weather might let you down shortly after your trip started.For a lot of comitted people that is no problem.The lack of power though can cause some to struggle to keep their video logs running.Your small drone might be great but it only lasts for less then 30 minutes until you need fresh batteries.Similar story if you use stabilizers, automatic tilt and pan gadgets or just a 360° camera.Just your cell phone alone can be a hassle if you use it as the main thing for GPS, pics and videos.At least one set of spare batteries seems to be a must have these days.For a lot of things it does make sense, for others not so much.Unless you really need ongoing power it might be enough to just charge you empty battery at the end of the day.But then the sun is down and options are gone for solar energy.In the RC area we can find a lot of powerful battery packs.Usually around 14V but 40 or more are no problem.And if you check the E-bike and scooter sections you will find some quite powerful and light weight battery packs.If you go outdoors a lot and for longer periods of time then it makes sense to replace the multiple battery options with just a single one.Use a high power backup battery with your solar system.DC-DC converters make it possible to literally combine everything with everything.Select the battery size so it will suit your charging needs and capabiliteis of the solar setup.Once time to close the tent you enjoy electricity to finnish your logs while your batteries are being charged during the night from the backup.4. Emergency generator.We all know these cheap gadgets like crank up torches or cranking mobile phone chargers.Nice to play with, utterly useless if you actually have to rely on them.A full charge for your modern phone might mean you crank for at least half the day - good luck!If you already carry a supply of gas for your cooking needs then these new fuel cells running on butane might be nice.Some of the Kickstarter projects actually made it into production!Prices though are more for real fans or those with enough money...But a small RC engine can drive some nice DC motor with very little fuel....In return you get a pocket sized generator that can charger your phone fully in the same amount of time a wall charger would...

Quirky tip on how to propagate roses?

Recently I found this little quirky tip on how to propagate roses/ bushes and I was wondering if it was true? In the little tidbit, they tell you to use a cutting of a rose of course and then put a little cinnamon on one of the ends that you intend to grow roots. Then poke that end in to a potato. Then bury that part with the potato into the ground. After I guess eventually you get a new rose bush. I was wondering can this actually work? Or is this just bait to get you to read more of their articles?

How much angle or curve needed for bike trailer tow-bar?

I want to make a trailer for my bike, but am confused about all the various types/styles of D.I.Y. tow-bars I see being made/used...how does the curve/bend of the tow-bar affect whether the trailer will track correctly behind the bike? If the trailer does not track correctly behind the bike then the tires will be ruined over time, and it will cause more 'drag' (harder to pull). I understand that the tow-bar needs to be able to clear the bike's back tire when turning, but if I put the wrong angle or curve in the tow-bar will it cause issues with keeping the trailer straight behind the bike and tracking properly?So how does someone determine the correct angle/curve of the tow-bar, besides trial and error and possibly wasted materials? Thank you for your time and assistance.

How much is granite worth?

So today I went down to some local woods with a hammer (Geode,granite,marble hunting) and I saw that 2 friends of mine had dug up a 20-30 pound rock. It was a heavy little bugger. So I swung the hammer at the rock for half an hour until I had about 30-50 small chunks of granite. The main reason I broke it was so that me and my friends could split it. One of my friends didn't want it. The other friend wasn't allowed to have it. All that was left was me. So I then realized that it was way too much to carry around. So I told another friends that didn't help do anything but polish the freaking thing with a brush *pauses and laughs* that I would give him all of it but 3 peices. I'm starting to regret saying that. So I wanna know... is granite worth anything/expensive?

Wearable that vibrates on text/sms

I am looking for a way to make a wearable (bracelet or hanger) that will vibrate when I send a signal (i.e. text message?). It's intended use is to alert players to certain pre arranged situations in a game. As coach I can not always reach my players across the field by voice so I want to send an alert signal. Also this is more discreet. A smart watch is to big and volnurable. Bluetooth does not have the range so I am thinking gsm. Any suggestions on how to build such a device?

Non lethal poison blow darts.? I was thinking about making blow darts then the topic struck me, could common natural non lethal poisons or toxins be used in blow darts. This sounds a bit vague, so heres and example: you take poison ivy leaves and either wipe the darts on the leaves or grind up the leaves then rub darts in the mix. Would this work, how effective would this be?. I am not planning on even attempting to try this, this is for informational purposes

Instructables as an Extracurricular

Really weird question. I didn;t know where else to ask. So I really love tinkering, building things, and making Instructables. I'm applying to college and thought putting it on would be a good idea. However, I really don't know what to 'call' it. if the admissions officers don't know what Instructables is - it looks really weird. Online Tech Blogging would be a wrong way to phrase it. Tinkering is far too general. I'm looking for a short and specific term that includes my love for building/making stuff, and my interest in instructables. Thanks for the help, and I'm sorry if this is the wrong place to ask :(((((

I think I inhaled a bit of cement dust...

Although I did my mixing outside (on a semi-rainy day) and held my breath while pouring the cement powder, I think I might have inhaled a tiny bit. Not a lot, but enough for a bit of coughing afterwards. The coughing is over, but my throat now feels slightly sore, but not bad enough that I want to contact a doctor. Mostly just a bit irritated, that I hope will pass. But can I eat or drink anything that might help this pass quicker? For lubricating the throat or something. Or will it go away eventually?

Cutting PVC Pipe - Lengthwise for guttering

Ok, here's one I thought I'd throw open to the masses.... I'm knocking off the last of a fully automated self-sufficient watering system that runs completely off grey/rainwater. However, the coke can guttering is not working in this position as it has previously :(  I was thinking of using PVC piping, cut lengthwise for guttering. However, I'm working out the logistics of cutting it. It can't be cut directly in half - this would be too shallow to catch the runoff from the chicken shed. and funnel it down to the tanks, so I'm looking at removing a chunk of the top.  And I also have no table saw. Wheee. What I do have Dremel (x2) with associated cutting wheels Jig saw (With associated plastic cutting blades) Circular Saw Mitre saw Hand saws (tenon, crosscut, hack, pruning, etc) So, here's one that I'm throwing open. With the tools I have, how would you do it?  I'm leaning towards the dremel, but there would probably be issues with maintaining a straight line (not that I care about some warp, it's a gutter)   Ideas? *EDIT*  Ended up using a jig saw with an acrylic cutting blade. Worked a treat.

The cost and downside of modern life

In another topic we noticed that times have have changed in terms of repairs, spare parts or just finding a replacement for something. It not only seems that a lot of people no longer bother to repair their broken things but also that for those who still want to the available options are disappearing fast. Take the common lawn mover as an example: We can buy them in dedicated shops, the local hardware store, supermarkets and sometimes even at Aldi. But if you need such a simple spare part like a fuel hose or gasket for the carby you are usually lost unless you can order the parts from some online store at the other end of the world. Electronics are even worse, here a broken charging plug or just loosing the charger can mean people throw it in the bin to buy a new device. Splicing a rope? Why bother if a big bunch of knots does the same LOL Do you still remember these little repair shops that used to fix your waching machine, TV or sometimes even your electric drill? Where are they now? Or all these small electronics shops selling resistors, wire and complete kits? I still remember the times when I could take my radio to the local shop, the guy listens to the sound and lack of available stations and knew right away what parts I needed - and they were right at hand. For a few bucks extra he even replaced the broken bits if he had the time. After thinking a bit about all this I came to realise two things: a) We are getting lazy and no longer learn vital skills because modern life makes us think we no longer need these skills. b) Unless you can repair something yourself, labour costs mean a repair is often not worth it. Who here, under the age of 30 still knows how to make a good campfire from scratch, dares to take the lawnmower apart to fix it himself or simply bothers to stich up a little rip in his fancy tent instead of buying a new one? For crying out loud, a lot of kids don't even know how operate a washing machine by the time the lease the parents home for good... Schools seem to support these life changes by no longer teaching the use of pen and pencil, not to mention ink... All the kids get is a tablet or laptop and that means they don't even have to learn the language anymore - that what the spell checker does. If I dare to spin this further by another 25 or so years I only see chaos. Everyone is highly specialised, noone bothers to cook anymore and the third generation in the family no longer has any clue what the first generation is talking about. When my grandfather grew up life was hard. When my parents grew up life was all about expressing yourself. When I grew up life was intersting because everything was changing so fast. When my kids leave the house what will they say about this?... What do you think ? How much has modern life affected since you grew up ? And of course: Do think it is the right trend ?

Underwater Jetpack Project. [HELP NEEDED]

Im planning on making an underwater jetpack something like this. However I'm a bit to dumb to figure out all the ESC and electronic components of brush-less motor systems.   Im also limited because this is a school project and in order to be reimbursed the materials need to come from amazon.  I will be using it in a chlorinated pool for demonstration but salt water resistance would be nice.  My requirements are as follows:  1.  Propeller must be covered as I may do another project after this one that requires fingers (im thinking 6in diameter pvc pipe with chicken wire or a metal grill over the ends) 2. Modifiable for different circumstances.  (I already cut up an old backpack and screwed a plywood board to it for mounting the propellers and  batteries, however I may decide to go with hand or foot mounting instead.   3. A trigger operable switch. (Cordless drill style although I don't care that much about speed control.   I'm planning this project to be for a senior year high school project (next year) so I have plenty of time. Do you guys think something like this would work for the propellers?  Their for air so I would expect significantly reduced performance in water.  However if they are to high rpm/low torque to spin properly in water perhaps I could keep the enclosure and switch out the motors for higher torque ones.

Coin a phrase, or one liner

Have you ever wonder were, phrases come from like  " That's what she said " or  "See you later.......not if I see you first" or "Well, there's your problem!" I think i may of coined a phrase, but of course I can't prove it  " Its funny cause its true"   I even heard it on TV the other night, I have been saying that for years. Anyways today after a student made a mess I gave him a mop and bucket and told him to clean it up. After 20 minutes I came back and he had managed to make the mess about 100 times worse. I was very annoyed with him and I was inspired to say  "Never send an idiot to do a job a monkey could do" Anyway there is, If it takes off I will now have proof that i said it first on 20 april 2016 So whats your favorite phrase or one liner?  Maybe you could come up with the next "That's what she said!"

Hi, I'm a soccer coach.  I'd like to make some inexpensive posts to serve as obstacles/markers that I can use indoors.  I have 5' pvc pipe, but can't seem to locate or concoct something to hold the posts upright both affordably and that aren't too wide to get in the way of the players or the soccer ball.  Ideally, I'd have something that is only a few inches wide with a 3/4" hole in the center to hold my 3/4" pvc.   Thus far, the best thing I can come up with are a few 2.5/5lb thick plastic weight plates where the center hole happens to be just about 3/4" wide.  Those seem to quite difficult to come by though!  The next closest thing I've found were either heavy steel flanges or rubber mounts specifically designed to hold plastic posts.  At $8 or more/each though, I was hoping to find something a little less expensive. Anyone have any ideas?

Making Copper (II) Chloride From Acid and Copper

Ok, so last 4th I made fireworks for a small- and I mean small- display, and it turned out fairly well. I only had two complaints- a) It wasn't that colorful, as I was only using pine and palm charcoal for color: reddish orange.b)it wasn't electrical, and took alot of visco, as I wanted everything to go off near-instantaneously. Well, I am going to solve problem b by getting e-matches off of Skylighter, but solving a is a little harder. Then, I read that certain copper compounds could be added to create a green to green-blue color in the flame. Well, I like that idea, but I didn't know where to get the copper compounds. So I kinda left it. UNTIL TODAY!I found this page on making copper (II) chloride. Well, it seemed straightforward enough, so I was going to try it. I was only wondering about two things:a) why on the description on this page about it include hydrogen peroxide, but the page does not even mention it?b)is this safe? I guess I should be outside for the hotplate part- I can't imagine boiling/simmering HCI, inside.c) is this even possible? Does it: 1)create a form of copper that could be used with success in pyrotechnics? 2)create copper chloride at all?Any answers are appreciated. Even if they don't directly pertain to the topic, POST ANYWAY! Makes it more interesting.

can you help identify kite parts

I wondered if anyone could help me identify some kite parts.  I won a huge lot at the local auctions including literally thousands of kite making parts. (I have a lot more not imaged here) Unfortunately, I have little experience with kites and the scale of the volume I have acquired is a little daunting. So I thought I would ask the experts for help :) So far I think I have managed to identify the following: 22,000 4mm end caps 6,000 3mm spar/eap 1500 i think small douge (the yellow things that look a bit like bullet casings .. they could also be end caps but i am completely without a clue on this one) 500 rubber bands 6,000 5mm end caps 3,000 6mm end caps 8,000 3mm rubber gromets Tones of name tags I know there are a number of notched end caps I think the curved bits of plastic were 3 rods can attached are called dihedrals. 65 kites The fabric parts of around 10 large kites made by greens of Burnley (a lot of them branded as the pioneer range) I haven't measured but im guessing around 9ft across I think the lot originally came from Greens of Burnley who are no longer trading but I have found their archived site https://web.archive.org/web/20060818054031/http://www.greenskites.com/spares.asp If you could help by identifying some of the parts/ what the pioneer range of kites is possibly a place where I can sell some of the kit (there's far to much for me to work with here) I would be relly grateful :) PS ill put up more photo's if anyone is interested.  PPS I have just found some info on the Greens of Burnley kites http://www.ebay.ie/itm/Vintage-CODY-War-Kite-1-GREENS-KITES-Greens-of-Burnley-Large-Frame-Box-/401079737121 PPPS I found the original image I think I have a few boxers from the range. http://www.kitelife.com/wp-content/uploads/2012/01/Kite-Lines-v7-3.pdf

Making this ethereal paper bird lamp

I wonder if anyone has any suggestions on how to build a lamp that looks something like this (Perch Light by Umut Yamac). This one was made out of archival paper and solid state LEDs. I can't tell whether it's nothing but folded paper or has glued components.

Electricity Free, wind powered Air Conditioning system from an old fridge

Has anyone ever thought of connecting a compressor from a refrigerator to a wind turbine and making an electricity free AC system for their house? It could be made from all free parts - turbine from barrel (vawt), dead fridge, etc. Please comment
