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!

Question by sdds    |  last reply


X is always happy Y is sometimes sad

Hi One and All, New here and new ish to electronics. I have put together a physical test environment with a 450watt psu from a PC, an Arduino UNO R3, CNC Shield v3 - this is driving 3 dvd/cd rom drawer stepper motors via 3 A4988 drivers. Firmware uploaded as gbrl v09 using XLoader and running some test g-code using UCG. I have set V-ref on the drivers using a multimeter balancing motor function and heat. Well, there is in fact a very small voltage window where the motors work (.75 or thereabouts) the coils test at 10-11ohms.The issue! X, Y, and Z axis all work perfectly when run individually. However, from a blog (can't recall which right now) I have created some polygons for the 3 axis to draw/print. X and Y motors won't run at the same time when the code dictates. X always runs and Y just shudders but when the code within the same file dictates motor Y to run alone it works fine. Z works fine irrespective of what X and Y do. I have tried adjusting v-ref to no avail. Does anyone here have any ideas how I can get Y to run alongside X? Thanks in advance.....

1 bit x-y scanning laser projector?

A lot of the laser projectors I have seen have problems with seek times and stability. This guy seems to have done pretty well. Would it be possible to create a scanning laser projector with a single bit input? Replace the x and y galvo(or any other type) scanners with motor powered wheels rotating at a constant speed. This would create a filled in square of laser light. Then all you would need to do is send an off-on signal to the laser to create an image. It is the same principle as a black and white CRT TV. What do you think? Edit: I think one motor should be stepper and the other permanent magnet. If both were pm's it would only create a diagonal line. The pm motor would scan from side to side while the stepper would tick along at the refresh rate. I guess you are kind of running into the same problems as you would with traditional galvo scanners. Edit (again): With a high speed motor from a dremel (max 35,000 rpm) you could only get about 130x100 pixels with 24fps... hardly the best projector. Not to mention the extreme vibration you would have to deal with if you didn't balance it correctly. I guess I kinda answered my own question.

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

Transform a conventional ink-jet printer into a 8000$ laser etcher?

I believe everything is possible, with a little bit of help and that's what I need now. I can't build out those fancy CNC machine found here, since it's beyond my knowledge and skills. However, I thought about modifying a cheap ink-jet printer to make it into a DIY laser etcher this way: -Replace the ink part with a custom laser - instead of giving a current in order to flow ink, the laser will be powered. Laser requires different power level depending on the material, perhaps a potentiometer knob on the laser power supply could do it? -Remove any rolls and paper-only specification: instead, make THINGS able to go inside by simply destroying the printer, rising it up, and use the bottom paper rolls as the Y axis motorization. (The ink-jet head will be the X axis). Why would I do this? I have no idea how to programm small electronic chips, even less how to hook them up to computer or software. I, however, am able to print black and white images, and believe the black can simply be a signal to "laser on". I strongly believe this is possible. Since I can't, as stated above, mess with microcontrollers, I suggest adding potentiometers to the motors and laser and calibrate it myself, and adding physical marks (e.g: sharpie marks) to mark my settings. My question is: Do you think it is? What else could be required? Did I miss some obvious point that would render the previous idea totally worthless, and is this point solvable? Please comment :)

y should you use a pump in small hydroponics??? not needed in most cases?

Most small setups are keeped in the house where you stay. so a small sprayer is all you need if you keep your plants on top of a plasic sheet with water and clay pebels. a good layer of clay ball socked in water with the plants on top is not going to cause root rot. you can use plant pots or rockwool cubes and dosen`t mater if you don`t spray them everyday.. a heaing pad under the hole thing is also a good idea . the heat will cover a larger area by gently heating the water also this way is perfect for seedling just cover with a clear plastic sheet. humidity from the heating pad under the sheet will act as a heated propergater.   here is some music to listen to while you read http://www.youtube.com/watch?v=MMbcfYrkmxs

Plot a diagonal line? Answered

PD17200,11600; i am sure I should know this. I need to plot a diagonal line from 17200 to 11600  Obviously there are more X points than Y points. 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.

Okay, problem with hp pavillion ze5700- letter "y" scrolls across the display whenever a folder opens.

The "y" character scrolls  continually. I  disconnected laptop keyboard ribbon and hooked ext. ps/2 keyboard, then  reloaded  XP OS , then sub-out  HD , then tried to load XP again. No avail. Suspect hardware, no trace breaks seen,
