Hey, I haven't been on Instructables in a while... anyways I was wondering if anyone would be interested in an 'ible about buying, using, cleaning and maintaining a blowgun? I haven't gotten an Instructable featured in quite some time, so I'm only going to do it if I see some interest. Thanks! --popewill

Hello, I am working on a project that is solar powered. I am not sure what kind of solar battery i should get and equivalent solar panel to charge it.. and regulator --- The parameters are: The 'show' will take place every hour for eight hours during daylight hours.. Each hour every 10 mins the system will switch ON and power will be needed to operate 25 automatic car antennas that draw about 0.8amps for about 1 minute show time. So every hour I will be drawing 25*0.8*6 = 120 ? -- I am new to this so i figure my calculations are wrong as 120amps seems a lot -- the system will also be powering an Arduino board which will be controlling the overall timing and puppetering of the work ie some coil relays or transistors for lower power consumption. this project will be installed in Germany in the summer with average sunlight conditions .. From my reading up on the subject I understand that it is not good to drain a battery, ideally half drain is max...could someone please advise what values i need for battery and solar panel.. thanks in advance ..

The Gomboc is a "mono-monostatic" object -- a three-dimensional object that purely by dint of its geometry has only one possible way to balance upright.The challenge intrigued two scientists, Gabor Domokos and Peter Varkonyi, both of the Budapest University of Technology and Economics. They spent a few years doing the math, and it seemed as if a mono-monostatic object could, in fact, exist. They began looking to see if they could find a naturally occurring example; at one point, Domokos was so obsessed that he spent hours testing 2,000 pebbles on a beach to see if they could right themselves. (None could.)After several more years of scratching their heads, they finally hit upon a shape that looked promising. They designed it on a computer, and when it came back from the manufacturer, they nervously tipped it over, wondering if all their work would be for naught. Nope: the Gomboc performed perfectly. "It's a very nice mathematical problem because you can hold the proof in your hands, and it's quite beautiful," Varkonyi says.It's apparently similar to the shape of tortoise and beetle shells, explaining why these creatures can actually flip themselves back over.

Hey guys, I like to run in the rain a lot, however I am worried about my IPod being damaged. I have an older IPod Nano, and I do have waterproof earbuds. I was wondering if anybody had any ideas on how to waterproof it, or make a waterproof casing. The biggest concern is the large charging plug in on the bottom. I have looked for waterproof cases, but I did not see any that fit my needs. Thank you for your time and help

I've been looking for a way to make an airsoft mortar which uses either tension (by way of wrist rocket or similar bands) or compression (by way of a spring). I'm thinking it'd be similar to the trip mine here:https://www.instructables.com/id/Build-an-Airsoft-Trip-Mine/If anybody could give me ideas or post an instructable, that would be great. I don't want to use air compressors or light anything on fire, because it's just not practical mid game (that would also be just a manipulation of a potato gun). I also think compression or tension could be a lot safer if done properly. Any ideas on making shells to hold airsoft bb's and properly disperse them when fired would be great too.P.S. I'm totally willing to offer my input on the situation if somebody else wants to collaborate on such an 'ible.

You may have seen on the news that a Dutch chap claims to have flown under his own power from a standing start. Watch the video... I don't buy it - I think that... those wings beat too quickly to generate enough lift (compare to the beat-rate of much smaller swans, eagles and condors) the wing membranes don't show enough sign of being under load - they're too loose and flappy. the wings look the same on the down- and up-strokes the upstroke should push him down, because the membrane doesn't close up like a bat's wing, or let air through like a bird's wing. In fact, I reckon he's on strings. What do you think? UPDATE Thanks to those comments from The Usual Suspects - so it's a fake after all. I ought to point out, as well, that the BBC had been reporting this on their website as well, but the story has mysteriously disappeared in the last few minutes (I didn't provide the BBC link, since most non-UK readers are able to see video on their site).

When i say airsoft for "reals" i mean not springers unless it is a high quality sniper rifle. and by high quality i mean 250 for stock gun and 800 dollars more in upgrades... just wondering, anyone else rock AEG's, gas pistols, sniper rifles?.. etc.... familiar with brands like tokyo marui, classic army, ics, g&g, tanaka, western arms, etc etc. also... not playing in parks, backyards... in the house. or places that will ruin the sport by getting shot to death by cops. even if it does have an orange tip, cops come anyways when they're called. and yes they are ready to blast you away if they feel their life is in danger... legally too. i would know. personal experience which was years ago. by no means am i bashing people.. im not saying that playing with springers is not okay, i understand not everybody has the time or money. its just i noticed a lack of any airsoft instructables for those serious about the sport?... and yes i've spent well into the thousands for the sport, no i dont think its a waste of money, i have a lot of fun doing my thing.

If you could... Spend an hour anywhere in the universe, at any point in time, where would it be? Meet 5 different people, from any point in time, who would they be? Have any one "superpower," what would it be? For me: Place: Mars, about 70 years ago. People: 1) Ernest Chappell, actor on Quiet, Please!, a 50's radio show. 2) Wyllis Cooper, writer for Quiet, Please! 3) Eoin Colfer, author of the Artemis Fowl series. 4) Ernest Emerson, founder of Emerson Knives and the Emerson Combat System. 5) Mikkel Maltha, the keyboardist/ bassist/ backing vocalist for the Danish band CRYOSHELL. Superpower: The ability to alter my molecular density, rather like Seth's in "Race to Witch Mountain" What would you choose?

First things first, I've been a member of Instructables for 4 years. I made a separate account to post this for a number of reasons, including the fact that people I know in real life who don't know much about this part of my life could end up seeing this, and I really just don't want to deal with that. So. When you see this title you probably think "Oh, this chick learned how to do some sort of life saving thing on here and applied it to a real life situation." No, not quite. Lets start with the background story. I was 14, and had gotten in trouble for something stupid. I was quite upset about it and had recently learned about something called self harm. Seeing as I had heard that self harm can help people release emotions and generally feel better about things, I tried it. It eventually became a habit. I'm not sure if the self harm played a part in my spiral into depression or not, but it sure didn't help it. Along with the depression came, unfortunately, suicidal thoughts. I thought about it a lot. How I would do it, when I would do it. All that. I believed that I'd probably end up going through with it by the time I was 18 or so. Now fast forward a bit. To when I was about 15. I was browsing Ibles one day and discovered this Instructable. It's a good Instructable, but nothing really stood out to me. Until I got to step 8. Where I saw this: "Never ever think that you're not worth it or life's not worth, read the next step on all the crap I've learnt from without ever having had a suicidal thought, you're much better off being alive than dead, it's disturbing to think that people would do something so stupid, wasteful and futile." Now, Killerjackalope was one of the members I looked up to on here, and this quote struck very close to home for me. I couldn't help but remember it. I made a promise to myself that no matter how bad things looked, I wouldn't attempt suicide. Promises to oneself are easily broken, as many of you may know. But this one for some reason wasn't. Every time I considered suicide, that quote came to my mind and made me think "What about the promise you made to yourself? You can't break it." I'm 18 now, and I've come a long way from where I was then. There's been many rough patches, but through it all, I haven't broken that promise. Not only did that single Instructable help me, but the site as a whole did too. The projects, the community, that sort of stuff, all helped me. Making things made me happy, and posting projects on here was rather therapeutic.

I think I have close to eleven bikes in my garage right now (sort of unfortunately), though I only really ride three. for road/ commuting, I have a pacific voyager toys-r-us mountain bike that I converted into sort of a timetrialing singlespeed, complete with a shimano 400 crankset, profile aerobars, champion bullhorns, a look carbon fork, alex 700cs with hutchinson tires, and lots of other ridiculous things that don't belong on such a frame. I ride a diamondback venom park bike for bmx which I found at a garage sale for five bucks, not knowing just how good it actually was and my gary fisher bitter has been decommissioned due to a faulty front hub which blew out my axle and almost ruined my fork, so I'm slinging around a specialized rockhopper on the trails whose back wheel I destroyed and as a result, I've replaced it with a wheel off a peice of crap magna my friend left at my house a while back. I've got several others, but these are my ladies. they come and go quite often for me, but that's what happens. so what are you riding?!

Altair ,the protagonist of the game Assassins Creed has a hidden dagger attached to his arm which is obviously spring loaded, but he unsheaths it by pressing a button with his pinky and retracts it with the same. I wanted to know if it is possible to make such a contraption and how it would work just to satisfy my curiosity. There are a number of videos on youtube but most of them are gravity driven or do not give any explaination so I'd be obliged if someone helped me out with this.

Hey, I'm much more of a mechanical guy than an electrical one, and yeah, I'm trying to be won over, but I think this project might help me bridge the gap if I can get it rolling. what do you guys think about buying maybe six or so friction light generators and disconnecting the lights, putting two on the front wheel, four on the rear, (they rub on the side of the tire) and wiring them all together to produce a power source? like I said, I'm horrible with electrical stuff- maybe you could even build a larger generator like I saw in another instructable, but do you think it'd be possible to either create a car-adaptor-style outlet, or even a functioning regular power outlet with that idea? what about an electric bike that charges itself while pedal in that sense? talk to me people!

Just thought I'd share a time lapse video I made last year (but just got around to putting it online) Two of my kids are involved with a local circus and last year, said circus bought a geodesic dome to use as a venue for shows. There was great excitement when it was delivered and put together for the first time. It seemed appropriate to record the momentous occasion, but knowing how long it was going to take, a normal video was out of the question. So I set up the tripod and camera and took photos roughly every five minutes. The first photo was taken just after 9am and the last one was taken just after 5pm. It's quite an interesting structure and so strong, they can rig the aerial apparatus from just about any point!

Today in gym class we "played" lacrosse, and by play, I mean we threw and caught the ball. Still, it was mucho fun-o! I think I would like to play lacrosse, or at least get into it more. I seemed to excel today, and I do like contact sports. The problem is, I don't have much training in lacrosse. I do know that it is similar to hockey, both in field and rules. Another thing is that my (future) high school does not have a lacrosse team. Only 2 of the 4 high schools in my county have one. I could play for rec, but what I am thinking is: Do you think I could get my high school to support a lacrosse team? So, everyone (and by everyone, I mean you, Brenn10), do you think you could help me out learning about lacrosse? What do I need to get started and practice? Do any certain body sizes excel at lacrosse more than others? Thanks, Bran!

This is just crazy - two Ocean Engineering students created a "hamster-powered submarine" from "materials derived from common household objects" that connected a hamster wheel in a sealed, air-supplied vessel to a propeller, allowing hamsters to take themselves on aquatic jaunts. (via BoingBoing Twitter feed) Seriously, it's a submarine powered by a hamster in its wheel. I can't decide if the hamster is having loads of fun, or is being driven mad with terror. It doesn't seem very fast, though... They documented the build on their own website, but if you would like to see an instructable on it, go to the video and leave a comment to say so...
