Can someone help me code for the bare conductive board?

I recently bought an arduino and bare conductive board and really need help trying to code three things at once. So the idea is to use a servo motor, audio speaker, and lights to go off when in proximity of the electric paint. The project itself is having a mouth open and sounds/ lights come on. From what I can tell I can get the audio with bare conductive board, but not sure how to hardware the servo and the lights on the board either. I can see online its possible to hardware the arduino with a bread board with sensor coding, speakers and lights, but for the audio its beeps. With the bare conductive you get the mp3 storage capacity.

Possible replacement PSU for PC? Answered

I am fixing a PC for someone and I believe the power supply is dead. I have been looking for a replacement but can't find one exactly the same. It is also from a 'slim' model PC so the psu is smaller than normal. Here are the specs of the original: Input=100-127v ~6A, Output=220W, +3.3v=13A, +5v=14v, +12v=14A, +5VSB=2A, -12v=0.3A. I was wondering if this one on ebay could replace it. Do the Amps and wattage need to be exactly like the original?

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,

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? Or am I just "screwed"? :-)

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.

Making a personal game system

So everyone and their grandma has posted and made articles for how to make a "universal game system" that emulates the actual hardware of a console on something like a raspberry pi. But my question is this: is it plausible/possible to create your own, unique, personal gaming console? I mean something that doesn't emulate, but rather is an entirely different system (not an NES or Sega, it's a "You-console"!). I understand some criticisms for this: "Why re-invent the wheel? Or at least the console...", "This is too complicated...", "You're stupid" and etc. etc. My reasoning for this is this: Why not? Heck, what a niffty thing to have under your belt to say "Hey, I developed my own game system and make my own games for it! I'm cool!" So what do you guys think? Is it possible? Has someone done it? If not, you guys have any pointers on what to do? I'd like to do it, but I'm not too electronically edj-imukated. Maybe it'll be something I tackle in the future, but I'd like your input first! :)

If you have have you gotten frustrated because your design has to be different and very from the previous design because you had to work your way around limited documentation? Can you realy make a improvement if more than one change is made fallowing the scientific method. For example lets look at a recipe: You are going to make a cookie. You will need these ingredients. What are their manufactures , manufacturer part numbers and suppliers? These should have sources on the internet because you are expecting some one to build off of this. You use measurement devices to put the ingredients together in steps.

I'll be using a picaxe, either 08 or 18x, and I was wondering what hardware to use for RF transmission (remote) and receiving (please don't just tell me to take apart a toy car, I don't have one on hand and I want to do this myself). Also, some tips on how to code this would be great. Oh and parts wise I'd prefer to buy through Sparkfun, especially as they're going through the whole getting sued by SPARC thing. Thanks!
