Fun with a Y connector

So I got one of my friends to come over, and we played with knex. He decided to have fun with a Y connector and pretended it was a nose and lip piercing. I thought it was funny, and took pictures, then I decided to post it.

USB Y Split for power

I've just got a simple question, which I was surprised to not find anywhere. A long time ago, I had a portable drive which had a single usb cable to two ends. One end had data + power, and the other end had just power. This was to supply more than 5v to the drive. I want to recreate this, do I need to do anything except splice another cable (with just the power + ground) into the one I have? Do I need to put anything in between them? Thanks, Ivan

[HEADPHONES] Y-Part Cable Fix

Hi guys! I've read quite a lot of threads on this, but could not find anything related to my problem. I need some help with fixing my headphones. I've managed to break them exactly on the Y part where Left and Right headphones connect to the main cable. I want to solder them however not sure how to connect separate cables... I have a small schema here: http://i58.tinypic.com/24vnptf.png Please note the Copper(orange) and the Blue(Blue) are together: blue is in plastic? coating with wrapped copper around but its two separate wires. Also, the magenta/violet on the diagram represents a white wire, All of the other cables except blue were coated in enamel?. The headphones have a built-in microphone with a button and its sony mdrzx610 model. I really hope there's someone to help me out I need my sounds back!

X-Y stage for film scanner

I'm building a film scanner using a dlsr. Here's a picture of the rig so far: Basically there's a light source, negative stage, negative holder, camera support stage, camera and lens.  I put a negative in the negative holder and slide it using a guide such that I can take a bunch of pictures of the negative at 1:1.  For example, it takes 25 pictures to cover a 6x7cm negative.  The individual files are then combined into one file using stitching software.  The system works very well, but it's a bit tedious.  I'd like to automate the negative movement using a diy motorized xy stage.  Many of the designs I've seen are for much bigger units, such as for a cnc machine, or units that require speedy movement.  That's not the case here.  Each movement would be only 10-20mm. I'm fairly handy, and I can follow directions/recipes well, but I haven't worked with arduinos or stepper motors before.  Any advice or suggestions on a good way to accomplish my goal would be very welcome!

Difference between all the X,Y and Z axes?

Hello, I am new here and only registered to get access to a CNC build which I really like. Now m questions is, as I look at so many of the builds, what defines the axis? Some use Z to go up and down, others mentioned it being the Y-axis, even saw a few saying X. Is it up to the builder or up to the software? Kind regards, Red

X Y Zach humbly asks for your help...

Hey there Brochachos,            Ok, having just dug in on my first project, I'm more than overwhelmed by the sheer volume of 'stuffs' I need to learn to accomplish my goal.  Howevever, having done a substantial amount of reading, I believe I've got a fairly focused question that can hopefully pull a concise answer out of the beautiful woodwork of this community.  Onward... I'm trying to interface a gantry style xy table that uses some softpots as positions sensors for the x and y axes.  I want to send this analog signal wirelessly to two servo motors that will respond to this analog signal accurately, with minimal latency, and no jitter. As a fairly new egg in the DIY self world, I stubbornly cling to Arduino for comfort and the xbee modules seemed like a good fit, but the workaround to transmit an analog signal seemed troublesome and the servos always seem to develop a Parkinson's syndrome of sorts. (at least with the builds I saw). The question...   What transmitter/receiver is both extremely amateur friendly, with regards to setup, and can also get the signal (sans Internet connection)  at least 100ft to the receiver where it gracefully manifests itself on the servos as smooth motion.  If you don't have a definite answer, pointing me in the right direction of relevant reading is also greatly appreciated.  If there is anything I've left out, just ask.  Thanks in advance, I love you, but not like that... -Z

iPad/Tablets for Disabled with robotic X/y plotter

HI all! I develop tech stuff for people with very significant physical challenges.  The iPad has been a great boon to those disabled persons that can use their fingers/hand to access it.  But this leaves quite a few of the people I work with left out. I wish to create a "plotter", similar to the old CAD/CAM plotters, with the movable X and Y coords that would be adjustable for iPad, and the Androids, Nooks, Kindle, etc.  It could be controlled, by the disabled user, by joystick.  When the destination is reached, they would press a joystick button and a 'pointer' (instead of an ink marker) would tap down on that spot.  I realize that many of these tablets require a capacitive touch and I have found pointers/styli, that seem to get around this somehow, so it's the robotics portion that I don't have experience with. Would anyone be available for contracting to do this? RJ :) rjcooper.com

Is there a handy algorithm to work out how may X points to ploy against Y? My current solution is to extract the difference - 5600 and divide the Y by that  11600/5600 = 2.1 So you plot 2.1 Y points for every X point. Somehow this seems wrong? i am sure I should know this.

Can using logarithms overcome scope insensitivity bias? Answered

Say you perform the following type of psychology experiment:You describe an undesirable event to people,tell them that X instances of the event can be prevented, andask them what they would be willing to pay in order to prevent those X instances.The responses you get (Y) are not even close to being linear with respect to X, but ratherthe responses are roughly logarithmic. That is, X=ABY, or Y=logB(X/A) for some constants A and B.So does anyone know of an experiment (or real-life situation) where subjects are asked to answer in terms of log(Y) instead of Y? Do such responses show a linear relationship to the corresponding X?

Motorized Panoramic head with microcontroller

Hi All, I want to build a motorized panoramic head. It must be made in PIC or ATMEL because I have only these options. Arduino board are not available to me  How it works.  Its basically controlling two stepper motors using inputs from photographer. Photographer inputs values in parameters and than microcontroller uses these parameters to rotate camera frame and take pictures. Parameters are as under: There are two stepper motors. One motor rotates frame of camera on x-axis and one rotates it on y-axis.  1. For x-axis motor parameters    a. Total numbers of steps to rotate.    b. One motor movement = 1 stepper motor step or more. For example we can move stepper 2      steps in on movement    c. After each movement (point#2) It takes image or press camera button by using relay or optocoupler    d Time Delay : When camera takes picture it takes time to save on memory card. We can define time in seconds as per picture size.    e : When it completes total number of steps defined in step#1. It moves back to its zero position. 2. For Y-axis moto parameters     a: When first motor completes its full number of steps than y-axis motor is activated.     b: y-axis: Total number of steps      c: one movement = how much motor steps. just like x-axis motor parameter     d:   Time Delay : same as x -axis motor. time delay after tilting frame.      e: y-axis motor just performs only one movement. Than again it activates x-axis motor.     f: Panoramas are made in multi rows. so this process of x-axis and y-axis motor activation should keep on going. It is terminated when y-axis motor completes its total number of steps. So the whole process is like this Turn on microcontoller  Add parameters for x-axis and y-axis motors click on start button microcontroller starts rotating frame on x-axis Frame start moving in steps. Than frame completes its first x-axis turn now microcontroller activates y-axis motor. Y-axis motor tilts frame upper arm in one direction.   code checks it is Y-axis motor final movement or more to come. If more than it activates x-axis motor. X-axis motor starts repeating whole process which it previously did. Than after full movement on x-axis and it activates y-axis motor. This process is terminated when total movement defined for y-axis motor is achieved. CAN ANYBODY MAKE ITS CIRCUIT AND PROGRAM CODING ? I M TOTALLY BLANK IN MAKING CIRCUITS AND WRITING CODES.

Air Compressor/Vacuum Pump

I have a theory: You have your supply of compressed air. You connect that by hose to one branch of a y-connector. The other branch is connected to a hose that goes into some sort of fluid that you want to move from one vessel to another. The trunk of the y is your exhaust (in theory). So now I give, say, 15 psi out of my air supply and that shoud drag my fluid out of its vessel through the y connector to the destination of my choosing. Would that work?

Best cheap wireless communication?

Device x has a button and is 25 feet from device Y. Device Y needs to know when the button is pressed and activate device Z, but it has to be cheap and if I have a lot (A LOT) of these sets near eachother they still need to work without interfering with eachother. Best Solution?

How to repair my headphones, when the wire colors don't match ?

Here's the problem, My headphones broke due to lame construction, so i decided to fix them myself like i usually do. but this time I'm lost. each headphone cup has two sets of wires. Both are have one Yellow (Y) and one Red (R) however the wire coming from the audio jack has something different. it has Yellow, Red, Blue(B) and Green (G) I've connected Y to Y, R to R on one cup, And B to Y and G to R on another. only one cup works. I've tried switching G and B places, however still, only one cup works. can someone please help?
