looking for leather embelishments?

I am making cuff bracelets, where you wrap the leather or suede around the raw brass cuff.  however, before wrapping the leather, i sew on embelishments.  I have been unsuccessful in finding such large embelishments.  Conchos won't work because the metal on the bottom won't stick to the brass cuff.  any suggestions for website to check out?  i have been hitting dead ends for over a month.

how can i turn a 3 volt current into a 12 volt continuous current to keep a relay switch open? Answered

I am building an r/c tank as some may already know from previous questions, anyway my batteries came in and now i have gone to my local jarcar shop only to find out that the relays i require to run a 12 volt 9 amp current need 12 volts at 150ma to stay open! but the reciever from a toy rc truck can only supply 6 volts for which the motors run off and another 3 volts for which the servo runs off . so how can i amplifie this current into 12 volts continuous to keep the relay open? i know whats needed, the voltage will be doubled but the amphours will be cut in halfe or quarters or whatever the opposit of what is needed to make a 12 volt current. i need to know what it is i need and how to assemble it , i am good with most instructions and im presuming that this should be quite simple and similar to that of a solar powerd sla battery charger.

[GUIDE] Raspberry Pi 3g Internet Wifi Access Point (Optional script to sniff login details)

Wasn't sure where to put this, thought it might be of interest to someone in here :) As a project, I set up my Raspberry Pi as a 3g internet Wireless AP to strip SSL from secure websites and harvest the login details. I wanted to show how easy it would be for someone to set up wireless AP providing free internet, with the equipment hidden - maybe in a backpack - and sit in a public place grabbing login details without anyone suspecting a thing. In the future I would like to do this while running the Pi from a battery bank. Guide to set up Raspberry Pi as a 3g Wireless AP Tutorial on writing BASH script to harvest login details

Wacky bike?

You know at carnivals they have those "wacky bikes" Ride it like 6 feet or so and you win a little pocket motorcycle. I would like to make one. Not sure where to begin or if this is easy enough for me (I have no metal working tools other then a dremel and a grinder). Basically, the wacky bike is a bike that when you turn the handlebars left, the wheel goes right.

Advice for hydraulic master thesis.

Hello, I’m a civil engineering student and I’ve always had a special interest for electronics, sensors, and arduinos. I’m finishing my degree for which I have to develop a thesis. After some research and based on some articles, I proposed to my hydraulics Professor to monitor the solids transportation (at the bottom of a river) using a hydrophone. This idea consists on measuring the intensity/quantity of sediments (like rocks and muds) passing through a certain spot. These measurements are made using a hydrophone put underneath a seel plate – when the sediments pass beneath this plate they create impulses or frequencies, which will then be analyzed. What I would like to know is the best way to capture these frequencies through the hydrophone – mobile recorder, daw, arduino? I intend to connect the hydrophone to the computer, either through the arduino or through a sound plaque, but I’m afraid these solutions are more prone to the appearance of noise. The frequency range to analyze is between 10Hz and 30kHz. Will it be a good solution to connect the hydrophone to the arduino? Another issue in my mind is the handling of the data gathered – should I use excel, matlab or python? Thanks, Carlos Esteves

Farewell my robot army

Dear Everyone (and you know who you are), The time we've spent together has been unforgettable and I think you're really swell, but I'm afraid it's time for me to move on now.  You've always been there for me, supporting my every effort, from cheeseburger salads and microwave cakes to turning Care Bears into a coat.  I love you for that. While in your tender, sometimes tempestuous, embrace, I've grown and blossomed from a green intern to the editor of your food and living channels, and you've rewarded me with your support, comments, and continuous inspiration.  But now it is time for me to spread my wings and move on to new territories.  I will always appreciate everything you've done for me.  I will still be here, lurking in the forums, popping up in your recent feed, featuring your awesome projects, and occasionally feeding you a new recipe of epically unhealthy proportions or gratuitously kitten-themed craft project.  So this is cheerio, but not goodbye. I hold all of you in my heart, and I am not going far.  You will find me just across the internet at Betabrand.com, turning a new group of people's ridiculous concepts into ridiculously popular products and trends, just as we always have here. So be prepared for a stream of disco-fabric and other related Instructables as I transition into my new role managing the Thinktank division and test out new product ideas.  I promise not to stop making cupcakes, or putting bacon where it doesn't belong.  Be well, do good, and keep making awesome projects. All the best, Sarah

Creating a guide & looking for suggestions

Hi Folks. Following a recent renewal of my membership I find myself with a bunch of patches I really should give out. With that in mind I am thinking of creating a guide based on salvage, reuse & recycling of wood something anyone who has seen my own 'ibles will know is a subject close to my heart. It could be created from pallets, old furniture, decking, fencing or anything else as long as the main material used is wood that has been previously used for something else & saved from the bonfire or landfill by being put to a new use then it fits my idea. What I'm looking for from YOU is suggestions for 'ibles I can include, it could be something as simple as toy box or as complicated as a full suite of dining furniture, I'm looking for 'ibles to suit all skill levels but particularly things that involve readily available tools so while I wouldn't reject them entirely I'm not really seeking projects that involve CNC's & laser cutters. So if you have an old or new 'ible of your own or someone else's that has caught your eye you think fits the bill please let me know, of course I will take the opportunity for a shameless plug of a couple of my own so I have one or two to get me started ;-) For every 'ible I use I will award a Wood Reuse patch (thanks go to planetpals.com for the image) for the person who suggests it & if it's not you own the creator of the 'ible. Thanks for looking folks, I look forward to seeing your suggestions. NG.

Instructables Podcast

ShadyLogic and I have chatted for a couple of years about doing some sort of podcast, but we could never nail down exactly what we wanted to do. We've finally managed to come up with an idea that excites both of us, and more importantly isn't a podcast we've ever heard someone else do. In addition to this, Instructables is sadly without any sort of official podcast and we'd like to remedy that. With all of this in mind, we thought a podcast all about brainstorming projects would be fun! Instructables is all about the projects and the people behind those projects. Now while the projects on this site are amazing, We've met a lot of people throughout the years who didn't think they had a good enough idea for an instructable, were unable to push through a builders block (is there a phrase for that, a writers block for makers?), or just had the very basics to an idea that they needed to flesh out with someone. We want to be there for you, and bring those ideas out. Our hope is that this will not only introduce some people to our brainstorming process, but will inform people to different methods and techniques for creating things. We know there is an Answers section on the website, but the intention of that is for questions that have answers to them. The questions we plan on tackling here don't necessarily have a right answer, and if they did, we probably wouldn't find it. Wilgubeast was nice enough to present us with a question to practice on, and you can listen to that below and see what you think. This is something Jake and I are planning on doing every week, but we'll need your support to continue. What we need: Questions, problems, musings, goals, etc. Anything you'd like to share that you wouldn't mind us talking about in a very public space. We'd like to tackle different issues people might have and see what sense we can make out of them. It can be a project that you're working on, such as how to attach two things together or something you'd only just started thinking about making and want to hear some tactics for moving forward. We'll pick a few questions every week and do our best to hash out any issues that we run into while discussing them. You can post any questions or quandaries in this forum topic for next weeks recording. We hope you like the idea, as we're very excited to present it to you. Attached you'll find the pilot question for the Instructables Podcast: How Do I? ----------------------------------------------------------------------------------------------------- Update 1: Well, unfortunately it looks like we spoke to soon. Jake and I really wanted to do this, but it looks like our schedules just won't allow us the time. Between living in different countries, graduate school and full time work, we just weren't able to to line up our schedules. We were hoping we squared this away with our practice rounds, but it seems we weren't quite thorough enough. Neither of us wants to try to do something like this if we can't stick to any kind of schedule, so we thought it would be better to nix it now before it progressed too far. We apologize if we got anyone's hopes up. ----------------------------------------------------------------------------------------------------- Update 2: And now it appears I've lied to you. Jake and I put our heads together, remapped out our schedules and we found that we should be able to manage to do this so long as we put the podcast out on Fridays. I hope this works for everyone! Thank you for bearing with us as we figured this out!

Instrument Topics of All Kinds

Hi all! I'm new here...nice to meet ya'll! I think I get how this site works, and it seems really awesome! Who needs the DIY network when you have a whole online community :D Anyway, this forum seems to be for sharing personal endeavors, correct? Well there's this blog. It's not completely mine....it's a company blog. It has SO MANY how-to posts about mainly reed instruments, reed-making, and all sorts of things. That makes it relevant to a niche community, which may or may not be here on instructables? I just hope there's some oboist or bassoonist out there that I'm helping by posting this :] It's called the Midwest Musical Imports Blog. Yes, there are a couple self-promoty type posts on it (it's a company blog, afterall). But a majority of it is how-tos and instructions and such. Am I right to post this here?

How can a LED be flashed like a strobe, motion activated and installed outside to act as a security light?

This is about home security.  I have posted another security question on single LEDs in the same category. We have a remote house under construction at the end of a cul-de-sac.  My idea was to create some type of motion-activated single flash strobe or LED burst of light.  This light would be installed at the cul-de-sac and the motion sensor could be further away.  I just want to create this big flash so that any one coming around in the wee hours has to decide if they just had their picture taken and do they want to go further.  The strobe would just flash once like a camera flash, not flashing repetitively. So the final product would have to be weather and water proof.  The house is about 200' from the cul-de-sac but there are a number of empty, underground PVC conduits run from the house electrical panel which could be used to run out 120v or low voltage wiring. I've looked everywhere on the net.  The closest I could find were cameras that are made to take flash photos of animals at night and are motion activated.

Waterspout!

On my way to work this morning I passed an amazing sight: a fountain of water shooting 50 feet into the air. A fire hydrant had come off (I wish I'd seen that bit) and the water from the main was spouting to the sky. I've often been vaguely impressed with the concept of water pressure in cities - it just comes out the faucet! What is pushing it? You used to have to pump water to get it Up to where you want it. This sight really brings that home, the massive pressures running underneath the streets in modern cities. It's highly impressive. When I first arrived there was simply the waterspout, but fire trucks and firemen arrived very shortly and started playing around in the water. One almost had his hat knocked off by it. It wasn't clear what they were doing in there, and I don't know how they were planning to get it under control again. The grocery store on the corner lost its awnings from the weight of water falling on them.

device to read volume level in a room

I was just thinking that something like this might be handy for a teacher. If you had some device that could read the volume level in the classroom and display it in a bar format so the students know when they are getting too loud. It'd be nice to be able to say, "ok, you can talk with your group but stay under volume 5" or "if you keep it below volume 3, you'll get more marbles". Anyone know if this could be done and how?

But what I want is to plug it in to the comm system and have everyone on comm hear the music. So here are the two problems I have "they should have the same answer" I need the music playing in my headphones not to travel back to the source and I need the music I pipe into the mic end not to turn my mic into a speaker.
