Searching for Hardware

I'm desperately seeking hardware for a set of stilts I'm making.  I *need* certain weight grades, etc and am having trouble finding anywhere (online or in the real world) that gives me sufficient information on their products to be sure that what I'm purchasing won't let me down at a crucial moment, like when I'm surrounded by kids and might injure myself or them if I fall. I have looked on several websites (like McMaster-carr) and just can't find the info I need.  Any recommendations would be greatly appreciated.  Thanks!

Orthopedic Hardware

My mother is having her screws and plates removed from her shattered ankle, and I really want to turn them into something beautiful that she can keep forever. Does anyone have ideas for creative uses of these implants? I've been searching the internet for ideas, but no one seems to do something with these (or at least they don't write about it).

PID control hardware?

This is for a college project, I'm not asking for help so much as advice. I need to write a PID algorithm and have it control an electromagnet. The only experience I have with this kind of stuff is C++ and arduino serial communications (with processing, not C++). Obviously the goal is to make the whole system as fast as possible, so could anybody recommend a programming language and hardware interface I might look into? Arduino on the whole seems a little slow, and I'm not  sure how fast the serial communications are or if something like USB might be better. Thanks in advance.

Open Hardware Toolchain Survey

I'm not sure how many instructables readers/authors identify with the open source community, but what you guys are doing in terms of publicly documenting hardware projects is awesome and makes your perspective especially valuable.  The Open Hardware Toolchain Survey is an attempt to uncover a basic list of user/developer requirements that can be contributed to the documentation discussion and, ultimately, lead to a new generation of collaboration tools.  I would like to personally ask you to take 10-15 minutes to add your perspective and/or pass this request along to anyone you think might be interested. The compiled results of the survey will be made available and will also be used at the OSHWA's DocJam. Not sure if I can post links but you can just google "wareium survey" and it will be right at the top. Matthew Maier

Harware stores 80 Vs 30,000

Just out of interest... I was pondering as to whether the dimise of small chain harware stores is a world wide phenominum or is just an Australian trend... I am lucky enough to have started with my company, back when it was the type of store you could dash into and see Bob from electrical, that had that 1w LeD you were looking for, that never sells, just Bob has some stashed away just for special customers like yourself... Or Dave in plumbing that knows exactly what PSI rated pipe you need for the job..... Or even Tim in tools is still holding that $400 impact drill he ordered in just 'cause you said you wanted to check it out(even though he is not supposed to) Unfortunatley we have been taken over by a multi-million dollar company and things have changed.... Most of the old employees were sacked.... But some made it though... I have taking it apon myself to resurect the fallen company, one person at a time.... So far 5 of us remain (quality employees that LOVE our customers) I now am a manager and have trained over 15 employees. (these team members at times get VERY protective of their departments, which makes me wonder if I instilled a 'lil bit to much of myself in them) Those 15 have trained atleast 5 employees each... So far that's 80 employees... Hopefully this spontaniously continues... I might add, these employees act vastley different from the generic 16yr old kid, the new business employs, who doesn't care if a customers get's stuffed around for hours on end.... 80 vs 30,000 It's seems to be working as I have had MANY complements as to the QUALITY of service provided to customers, by these employees. In the mean time until we take control (I already have 90% of my staff converted to the dark side at my store ;p) It's off to go hide some LeD's, Switch's, Fitting's, Drill's etc down inside our racking so "other" managers don't find out and squeel to head office... Anyway's, is there any Bob's or Dave's left at your local hardware store that you can call on, for all those weird and wonderful things we needs to make all our Instructable dreams come true???

Say you had a giant wall designed for fastener storage....

I've been working on a project for the last week. When it's done I'll have a chunk of wall with: 90 1"x2"x4" drawers 64 3"x4"x7" bins 48 3"x6"x9" boxes My goal is to get all my various hardware organized and to fill in some gaps so that I always have a small handful of whatever size of nut, bolt, nail, lag screw, rivet, sheet metal screw, etc. that I need and don't have to go making a trip to the hardware store unless I'm doing something big and need dozens of something. So my two questions: If you had this setup, what sorts of less common hardware would you make room for? Where would you go to buy hardware to fill this thing up? I know if I go to the big box stores and buy those little plastic bags with four of this or five of that in them, I'm going to end up spending a lot more than I need to. I know places where I can buy hardware by the pound, so that will help keep costs down. But I'm also imagining that there are people here with on-line sources that might be cheaper still?

Embedded video solutions

I'm working on a project that requires the playing of short videos based on some physical conditions. The microcontroller and more general electronic end of stuff I'm fine with. What I haven't yet figured out is the mechanics of the video player mechanism. I want to use digital video stored on removable media (preferably CF or similar memory card storage). The videos will have no sound, be black & white, and probably low resolution (640x480 being the max size). I had originally planned to use an embedded linux system (gumstix verdex or some such thing) hooked to a TFT display. With some software running on the computer, it shouldn't be hard to control with serial communication. However, I'm not sure how well (if at all) mplayer would run on the Verdex. Also, if there's a cheaper solution I'd rather take that. I guess this post is to see what my options are. I know there are mp3 decoders on a chip (like the STA013) that produce output that you feed more or less directly into a DAC. Is there such a thing as a hardware mpeg video decoder (or divx, or quicktime, or avi, or whatever?) If something like that existed, I could connect the CF reader straight through my uC to the hardware decoder and pipe it out directly. Either to LCD or CRT (depending on which signal is easier). So, does this exist? Is it feasible? Thanks,

Hardware/software for indoor digital signage?

Hi, What I would like to build is a digital signage kiosk. I am using a 32" LCD display and wood for the housing but I can't figure out in which direction to go regarding the hardware/software which would breath life in this stuff. Room is not a problem inside the housing, so I could go mini or a normal pc, x64 or ARM. The interface would be rendered in HTML (+java script for animation), which would contain some short (1-2 minute) video clips, but overall the requirements are not that big. So here comes the software decision: windows or android??? Android with smaller lighter (energy saving) hardware or the ARM powered Raspberry Pi is tempting, but maybe in the future I would incorporate touch capabilities which may need a more sophisticated hardware...I am confused, which way to go????

Open Source Hardware Design Project?

Needs updates. www.slida.orconhosting.net.nz I have tried, with my limited financial resources, to market them but my problem is the high production costs and lack of finances. So I have been thinking about giving the idea away for free as an open source hardware design.  I am planning to start a community of people developing the idea and maintaining the design.  My strengts are design and problem solving. I have improved the original prototypes so now the current design has got not many bugs or flaws.  As I got the idea for my UUT from a design in Finland and they no patent either, the idea can not be patented.  And since I have not benn able to commercialize my idea, I am keen to give it away as an open source design. How to go about it?

Where can I get screws, nuts, bolts and other hardware most cheaply? Answered

I'm planning to build a car-top bike rack based on this gentleman's design: http://www.angelfire.com/vt2/tommymc3/BikeRack.html As I've been pricing materials, I'm pleased to find that the wood, pipe, tubing and conduit will cost me only about $20. I'll need to buy one tool (a rigid backsaw) for about $10.  I was hoping to get away with less than $100 out of pocket for a rack to hold four bikes, but then I hit the screw aisle. Picking out machine screws, nuts, and wing nuts for the uprights and jotting down prices, I hit almost $10 for those items alone.  Then I looked for galvanized angle brackets to attach the uprights to the base, and those plus the screws, etc to attach them were close to $35!  Once I started looking at U-bolts and other things I'd need to put the whole thing together, I got quite discouraged. So, is there a place to go where I can get those kinds of things at more of a discount?  I tried McMaster/Carr, but they sell only in bulk quantities.  Once I'm an old established tinkerer, I'm sure I'll have a workshop full of hardware bits that I can make work, but for now, I'm flummoxed.  Suggestions?

Get Paid for your Hardware Projects

Looking thru all of the cool projects here, it seems like there are too many projects that took tons of effort, sitting in attics. Or they're being used by the project designer, but no-one else can benefit from the designer's hard work. A lot of people would love to try some of the projects you've come up with, but they're not sure where to start.Here's what I'm proposing;- I'll keep a stock of the most useful components (passives, IC's, etc). I'll also keep stock of several 'generic' project PCB's.-You come up with a cool project using these components, Or modify a project you've already done. Once you've got it done, send me your source code / design and a Howto.-I'll publish your projects on my site, and I'll market my site to drive hobbyists. I'll spend real money marketing it, driving traffic so that thousands of folks will visit and check out your projects.Here's the best part; If a visitor thinks your project is cool, they can order the materials to build it. I'll take care of shipping, inventory, payment processing, etc, and I'll share the revenue with the project designer. Imagine if your hobby paid some bills instead of making them! And all you have to do is write up a 2 or 3 page 'How I did it' and share your code.HOW TO GET INVOLVEDI need to do a fair number of things on the business side, so I won't be ready to launch for 2-3 months. Before I can launch, though, I need to figure out what the inventory of components should be. There are two ways to get involved;IF YOU HAVE A PROJECTGo to the website and submit a brief description and a Bill of Materials (BOM). The BOM is the most important. Once I've collected enough BOM's, I'll build an initial component inventory for projects. Try to be thorough with the BOM (Everything but solder). Your project doesn't need to be done (or even started), but if you share your project now, you'll get priority listing when the site is launched.IF YOU WANT TO SEE A PROJECT AVAILABLEVisit the website and drop me a note. I'll collect project ideas and see if any designer are interested building it (or chase down a designer who already did).My goal is to let other folks enjoy your awesome projects and appreciate your work. You'll also be able to make some money with your hobby, too. All feedback is appreciated!To get you thinking, a few projects I've seen around or think people might find cool; 'IRC client in an altoids tin', Music Visualizer, C64 wiimote baseball bat, LED stock ticker, Homemade portable MP3 player, POV clock / 3d display, Guitar Hero kit, LED lighting system, 3d printer, Parking assistant, SIM card reader, Metal detector, GPS logger / tracker, Balancing Robot, Remote Camera recorder, PS/2 Keylogger... Whatever! At this point, I don't need completed projects, just an idea of what they are and the Bill of Materials.The only way to make this project viable is to limit the inventory depth. By submitting projects now, I'll be able to build an inventory that will best support your ideas.The website is www.gadgetgangster.com. Thanks in advance,Nick

How to tighten a nut on a threaded rod from the side, through a hole in a hollow tube?

Picture a threaded rod, with a hex nut on it. The rod is inside a hollow tube. You move the nut down the rod by inserting an outside hex wrench into the hollow tube from the top. But what if you only have access to the rod from the side, through a hole in the tube (which is fixed and can't rotate around the rod)? Is there a way to tighten a nut down a threaded rod from the side through a hole in a tube? Context: the application would be a grip for a fencing weapon. The base of the blade of a fencing weapon turns into a threaded rod (the tang). The bell guard (metal disc to protect your hand) has a hole in the middle, and is inserted onto the tang. The standard grip is a straight tube-ish thing (usually solid except for a hole the diameter of the tang). You stick the tang through the central hole in the grip. Then you stick a nut on the end of the tang (which just extends beyond the end of the grip) and tighten the whole assembly down. Some special grips are curved, which means that you have to bend the tang in a curve to match the grip first in order to fit it onto the tang. Another kind of grip is straight and hollow, with a plate with a central hole over the end butting against the bell guard, to give the nut a surface to press against, and the tang is cut much shorter than the grip, and you tighten the grip with an outside hex wrench from the back end of it, as I described initially. The advantage is that a shorter tang weighs a lot less, and the weight savings can be really good in fencing. I want to combine the advantages of these two types of grips- a curved grip, which is hollow and lightweight, with a tang that is shorter than the grip itself. Obviously, it would be impossible to tighten the hex nut through a curved grip, hence my question.

Starry String Lights?

Hi all, first time poster, hoping I am putting it in the right spot. Last night my wife brought home these awesome "Starry String lights" from Restoration Hardware (http://www.restorationhardware.com/catalog/product/product.jsp?productId=prod1730031). They look fantastic in the house, but she tells me they are REALLY expensive per foot. I was wondering if anyone out there in the community has ever done a DIY version of these lights and if so, would you mind sharing your technique? I would love to string these in several locations but don't want to pay the outrageous price for them! Thanks in advance, Jake

computer systems for an NGO?

Hello everyone, I am currently a volunteer at an NGO and I have seen that they use different systems for their daily routine and that they have much trouble with their existing system.  So they are now moving into an office space instead of having two differents units in two different houses where the staffs can work more efficiently. I proposed to help them with their existing system to solve some of the issues that I am aware of.  However now they want to have an overview of how to fix the whole system which is Hardware, Software, Infrastructure, ISO rating (future update, People etc.... Could you please help me on how to proceed so that I can propose a solution for them. Thanks
