Ok here is the idea, I have a main tower, plus a dozen or so old ones.  I wsa wondering if it is possible to some how link 2 motherboards so that one acts as a slave for the other.     First thought was that it may be as simple as running a cable from the ide ports.  That may be totally off but that is where I got the idea.    Target goals of theory 1. Additional disk drives- this would allow you to use additional HDD in the other case this was my primary objective. 2. Might the additional processor be able to split the tasks of the computer as a whole? In theory would it then be ran as 2 seperate computers or as one whole with dual processors (does such a thing exist?) 3. extra usb space. 4. additional vga outputs- I have 5 screens right now using the onboard, a dual port pci-e and a pci vid card plus a usb adapter one.  rather clusterry.  I have a additional screen but no card space for it.  I intend to eventually be able to use each independantly or as one large 2x3 screen for watching movies, but that in itself is not as of yet crucial to the theory. So can it be done buy this method or for that matter any method? If so how would I even start? I thank all those much wiser on this that I in advance

multiple arduinos in a network (mesh), with each possibly being both host and client.

Hello there, I am trying to put together a mesh topology of arduinos. I have never used them interconnected and now I am hoping to be able to put them together in a way that they may power up and communicate when plugged to one another. so I need them to receive both power and data connection from the one previously connected. for that, i think i need each one of them to be able to act as both host and client. am I correct? would anyone know more, and willing to help? I very much appreciate any feedback. Thank you, Karim.

How do I build a master control? Answered

I want to build a circuit that has several led groups. Each group has an on/off switch. I want there to be a master control switch that overrides the state of all other switches; i.e. when master control is on, circuit behaves normally, when off, all outputs are 0. How do I build this circuit? Are there any parts that can simplify the process? I thought of using a multiplexer but it only outputs one value and I'm not sure how multiple output multiplexers work. Thanks for the help!

I need help with an electrical schematic

I'm working on a project where you press a normally open button that lights an amber light (represents Master), this button then lights other buttons that are lit green (represents Slave). The accompanying schematic should be fairly clear and also repeats this question. What I want to have happen is when you press one Master, the corresponding Slaves light. Release it and the board goes dark. Then if you press one of the other buttons in the Slave category, it becomes the new Master and lights up other corresponding buttons. I'm sorry if it's confusing. The project is a flow chart of sub-subsystems that when completed link to a larger tab, then that tab links to another set of subsystems finally culminating to a final result.

I2C in arduino

Hi, I am trying to connect two arduino UNO together. Lets call one U1 and the other U2. U1 is master and U2 is slave. Now I want to attach a wave shield to U2 which is slave and operate it from U1. Is that possible? If it is possible, then can I use any pin to transmit and receive signal?? Cause in some forums they say that I2C is done by using digital pin 4 and 5. However, these pins are taken by wave shield. So please help me out in this.

Is this a simple RC buddy box system ?? Answered

Hi Guys, I have recently resurrected my interest in Radio Control Aircraft. When I was teaching I ran an after school club to build and fly RC aeroplanes - However it is very hard for youngsters to pick up the skills without excessive crashes. There is a system to over come this - The buddy box system available on many of the high end RC transmitters. 2 compatible transmitters are linked with a cord one is the master and one the slave. The operation of the master slave is by a switch on the master system. Now all of these radios are relatively expensive - £100s. where you can buy relatively cheap equipment without this facility for £30 or less. As far as I can tell the signal on the buddy box cord is a PWM signal which is passed serially from the slave into the master processor to proved the stick position information from the slave. My question is will the much simpler cct below work or have I missed something in my though process. I propose to cut the 5 volt line to the sticks in the master and insert a DPST switch This switches the 5 volts to the slave system which is un-powered. With 6 lines - 4 signal 1 +5 volts and 1 ground line I can provide the necessary position signals to drive the master transmitter. If necessary I can fit a DPDT switch and cut the ground line as well. Flicking the switch back will give control back to the master by switching the +5 volts. If this looks OK I will get another transmitter and do the modification - Have I missed something obvious here.

usb enclosure hack

So far, I have removed the original ide cable the came with the enclosure controller. And, installed my own ide cable. The only drive that is detected is the one jumpered as master, at either location on the cable(master vs slave). No matter what the other drive is jumpered as(slave, cable select), it is not detected. I tried setting both as master and neither are recognized. I have run out of ideas... suggestions would be great. And please dont suggest getting another enclosure. IM CHEAP!

Btw, how do I suppose to upload the files to Arduino properly? When I have the TX->RX0; RX->TX1 (Bluetooth pin to Arduino pin), I can't upload the file. I have to disconnect and upload, then it seems to upload but doesn't work properly. Thanks in advance.

switching on a device using a mcu

Also whenever I open the strip I put ambibox options on colors dynamics than they stutter for awhile until they warmup. then I switch the option on ambibox to screen capture for the rest of use, where under white light they stutter again( I guess white withdraw the max current and this cause the din line to "crash") i have the wires, resistor and cap connected appropriately following the tutorials online.  The V shows around 4.7 and the power connected to two places as I use 160 LEDs with 5V 10A PS.  hope someone can help thanks for your time

is there a fix to my ambilight 2812B endless malfuncion?

I am using ~170 LEDs (2812b) with a 10A 5V PS. the power is connected to two parts of the strips due to voltage drop that results in a yellowish white color, close to the end of the strip. I also added a 1000uF 6.3V Cap on the PS and a 470ohm Resistor on the Din starting point. GND connected to the Arduino and using Ambibox software. after a few weeks of usage and especially when turned on, the LEDs flicker or stuck on a certain color up until led (x). few minutes later it overcome whatever problem it had and works regularly. Alas, on white color (guess when it consume the max current) it start to flick again mostly on this led(x) again. of course, I replaced led(x) and led(x-1), enjoy a few weeks of the Ambilight project working perfectly and then another led(y) want my attention and again and again.... should I replace the whole strip? am I using too much current? is it a known issue?or there is a galaxy where these leds replacement slaving don't occur. thanks in advance

how do I connect 2 stepper motors for a single Axis using two different drivers (slaved drives so I dont lose current)?

Hello,    I am currently building a cnc machine and realized that if I use two NEMA 23 to operate the Y-Axis from one controller, each would get half the current, I don't really have an understanding of electrical components but I keep reading forums suggesting I slav two drivers together using one signal input, I found the wiring diagram for the cnc I'm building and was wondering if someone could explain it to me or draw a diagram.    My understanding is I can use another driver that is powered separately but I run the signal wires for both motors from the same source, would this work or would this cause hardware issues or destroy the board. I would really appreciate any and all help. I've included the image from the build I found, I was hoping someone could draw ontop of this or explain it to me in a diagram.

How do I connect several Arduinos through RS485 with the SN75176 chip? Answered

Hello, I want to connect several Arduinos together in a star network (1 Master, several Slaves), but they're too far apart, so I can't use I2C. I researched a bit and found that I can use the serial protocol RS485 and that I can use the SN75176 or the MAX485 chips to do it. Being the MAX485 more expensive than the SN75176, I bought the latter. My problem is: now that I have the SN75176 (I have two, actually), what do I do? I have no clue whatsoever. I found some circuits for the MAX485, but I don't quite get how I should connect them to the Arduino.. Anyway, the chip I have is the SN75176... The only thing I find with Google is about DMX - for lights and stuff like that -, but I'm not interested in that. I just want several Arduinos to send data gathered from temperature and humidity sensors to another Arduino... Thank you very much. :)

PPM vs PWM, why choose PPM over PWM and how does PPM work? Answered

I understand the basis of operation of PWM, however, PPM is what confuses me. What is it, and why would I choose to make a system for data transmission using it over PWM? What are the benefits? and also the drawbacks? I have a Skyfly 6 Ch radio Tx and Rx, it is even remotely possible to squeeze a slow serial data communication (9600 baud) down one of the channels reliably? I was wondering for simple non critical auxiliary mode control, I could have more than one thing controlled by a single channel on the radio, such as lights on or off, acro mode, GPS hold, and GPS return to home mode switch, and other auxiliary things by using a output of a microcontroller to multiplex all of those things with a serial data Tx. I do not want to make any major modifications, possibly use the S video port-like thing on the underside where another slave remote control can go.

Anyone know of a cheap Digital Video-Camera that has (or can be hacked to support) External / Asynchronous triggering?

Basically, I'm wanting to record something from several vantage-points (tennis-strokes mostly, but it would be relevant for things such as baseball or golf swings as well) using two or more cameras. The problem of recording with multiple-cameras is, if they're not triggered simultaneously, they could be capturing their respective frames at as much as 1/(fps*2) of a second (i.e.;16.7 ms for 30 fps) off from one another; which for many, if not most things wouldn't be a concern. However, since they wouldn't capturing the event at the exact-same moment, the usability of the video information for motion-analysis purposes is greatly reduced. For everything else other than lacking support of external/async. triggering, something like my relatively-cheap $120 ApiTek 60-FPS 1080p Camera (Std-Def would suffice) I picked-up on a whim at Walgreen's would fit the bill quite nicely. While professional cameras do have this feature (also referred to as a Master/Slave Camera Array), this is simply for my personal-use, and I'd have a hard time selling my wife on the idea that I need to spend multiple thousands of dollars on it.

IDE hard drive wont spin up in external array, using hacked power supply.....?

           So after building my new computer I had three old IDE 250gb and two 40gb hard drives.  I took some scrap aluminum and built a rack to mount the drives on. I hacked an old power supply and made a power supply for the drives. I bought 4 IDE to USB connectors and ran then into a USB hub. For some reason the power supply turns it self off a few seconds after plugging in the 250's. It will run the 40's no problem and the system instantly recognizes them.  The jumpers are all set to slave. When I individually try them with my single IDE to USB kit they work fine. 400w for just 5 drives should be more than enough power. Please help me out. Specs. Power Supply Antec-PA-412x 400W drives-250's WD2500-WD Caviar SE WD2500-WD Caviar Seagate Baracuda 7200.8 drives- 40's IBM Deskstar 40 WD400- WD Caviar
