Computer Drive Bay?

Hi all. I am looking to fill at least 2 of my 4 availible 5.26 inch drive bays in my "new" computer. I was thinking like maybe a fan comtroller... but thats a little boring for me. I want somthing really cool. I did consider a lcd... but its kind of expensive and well... just not... idk. I just dont really like that idea. I was thinking somthing lik a toaster. :D But really... i want something kool. i mean even somthing totally useless... I just wanna fill them. I did consider using 1/2/3 of them for resivours for a liquid cooling system... but thats a little hard 4 me rit now. I am on a budget. I already gotta pay lik 130-230 for a new mobo. But i still hav som monsy 2 spend on it. So, wat is the coolest 5.25 inch drive bay device u ever saw. I also have 2 3.5 inch ones for smaller things. Like floppy. :D In case ur wonderin, i hav a xion vantage case. I am usin lik 4 fans. 2 or 3 lite up. I will soon be adding cold cathodes. But anyway, u can see it in my forum topic that i will make once my pc is bak from shop. THANKS!

Hard drive won't mount?

So, I've had a toshiba 2.5" SATA 250 GB internal HD for a while now. I got it from an old toshiba laptop. I finally got an enclosure for it, and I plugged it in. windows made the sound it makes when you plug something in, and in device manager the usb port said a usb mass storage device was plugged in, but it didn't show up in my computer, nor did it show up in disk management. I searched the net for hours trying to find the problem, reading about how you might need to assign it a letter in disk management, and other more "grim" outlooks on how it might be dead. I listened to it closely, and heard it making very VERY soft ticking noises at a regular rate. I immediately thought the worst, and came to the conclusion that it was dead. The next day, I decided to take it into school with me, as my teacher was pretty smart when it came to computers, and maybe she could provide the tiniest shred of hope. She asked me to plug it into one of the school's desktops. I plugged it in and...it began running like normal. It showed up  on my computer, and showed the correct disk size, as well as a document I'd put on there long ago. I couldn't believe it!  When I got home, I plugged it into my computer, but surprisingly encountered the same problem. I decided to do a bit of experimenting, and I started plugging it into various computers we had around the house, and lined up all the facts I had: It didn't work on my laptop. (runs windows 7 home premium) It DID work on my mom's laptop. (also runs windows 7 home premium) It didn't work on my old desktop. (runs windows xp home edition, but I don't trust it. It's been acting very weird lately) It DID work on my school's desktop. (runs windows 7 enterprise) It DID work on my sister's laptop. (runs windows 7 home premium) I was stumped, to say the least. Can any of you tell me WHAT THE HECK IS GOING ON?!?!?! The strongest lead I have is that it might not be working correctly on my computer because the usb ports can't provide enough power to mount it. But if my laptop can't mount it, why should my mom's or my sisters be able to? Please provide any other theories you may think are plausible too!

Non SCSI, mega storage device?

So there I was, thinking that I had heard/read somewhere that it was possible to hook up many regular hard drives (IDE, EIDE) together to make up one logical partition that was dynamically expandable. I might be off my rocker, but I think I heard of it somewhere. An example is.. your company is upgrading it's computers, and intends to throw away old hard drives (i.e. 4GB, 20GB hard drives...) If you got your hands on them, you could hook them all together and make an expandable external storage. This would mean that if you have 3 20GB hard drives, you'd have a logical 60GB partition. Your buddy wants to throw away his old 10GB hard drive.. so you get that one and add it. Now you've got a 70GB hard drive. Has anybody ever heard of this idea before? No idea how to make it work, but I think in theory it would be neat.

Reformatting a hard drive? Answered

Hi there. I know most of you reading this are thinking of the simple process that is reformatting a hard drive, and are prepared to offer me an obvious and somewhat novice explanation as "right click > format...". Please don't, this is not the case. I recently acquired an external hard drive previously used as a Direct TV Dvr. The hardware and everything is fine, and my computer recognizes it as a USB Mass Storage Device. However, the disk itself is in a format my Windows-based computer cannot recognize, read, or understand, and - as a result - does not acknowledge it exists. I need to figure out how to reformat this to NTFS / FAT32 to use on a windows machine. Also note, as a result of the lack of recognition of the disk, I can only guess its drive letter. CMD does not recognize it at all - I have tried mounting disks E - Z with no result. If needed, I have access to a Macintosh, but that is preferably the last resort as it resides about an hour away from where I am currently.

Drunk Driving Bank

I am looking for ideas or a complete solution to locking up your car keys when getting drunk, but allowing access to the keys the next day to go to work or whatever. The idea is to make an electronic bank of sorts that you would deposit your car keys into and it would be time delayed, so you could not open it till the following day. Another idea is to make a breathalizer that you could make and install in your vehicle, and not have it monitored or have to make monthly payments on it as they are set up now. I know my son has good intentions of not drinking and driving, but we all know when drunk, your intentions are impaired. if people that wanted to drink, yet not drive, a setup like this could save people from driving when impaired even though they normally wouldn't.

Variable frequency drive

Hello there instructables, I have another question discussing maglev theory and i was directed that the true way to build this project was to use 3-phase power! So this question, although related, is also an entirely new project in its own right! Now to the point, i have been researching single to 3-phase conversion, and there are a few options available like rotary or static phase converters, but i have been intruiged by a device called a variable frequency drive! Okay so what i understand so far (i think) is that these convert ac to dc, run that dc through a H bridge rectifier using igbt's and then convert the 3 outputs back to ac...... okay assuming my analogy is correct so far, to my question, 1. How are the igbt's triggered in the h bridge? do they use a function generator with altering timesteps to create the seperate phases? 2. Also how are these kept in sequence with eachother? Many thanks in advance for any help you can provide!

Restore lost external hard drive files and folder after format

The day before yesterday, my external hard drive was dropped to the ground for a sudden shock. When trying to access it again on the computer, the windows just gave me a not formatted error and disabled my access without formatting, so, without deeper consideration, I formatted this drive and finally found all the files and folders were gone. What a stupid operation. In order to access my files and folders of the past two years, I began to crazily search for related articles and questions to see whether there was a way for me to get them back with success. Follows some recommended steps and data recovery programs, like: Firstly, stop using this formatted drive till rescuing everything back. Secondly, attack drive to computer and use data recovery software to scan this drive and rescue original stuffs back as many as possible. Thirdly, save all restored stuffs on another different drives or storage device at last. Fortunately, after trying these steps, I got most of my needed drive files and folders back with success. If you are also experiencing such data loss problems, you also can get some clues with my found articles, like: http://en.wikipedia.org/wiki/Data_recovery http://freeware-fix.blogspot.com/2013/02/external-hard-disk-format-recovery.html Or http://www.ucfix.com/data-recovery/data-recovery-after-format-external-drive-hdd.html Hope my words also can help someone there!

Another step towards human cyborgs - the finger drive.

A Finnish computer programmer who lost one of his fingers in a motorcycle accident has made himself a prosthetic replacement with a USB drive attached.Jerry Jalava uses the 2GB memory stick, accessed by peeling back the "nail", to store photos, movies and programmes.The finger is not permanently attached to his hand, so it can be easily left plugged into a computer when in use.Mr Jalava says he is already thinking about upgrading the finger to include more storage and wireless technology."I'm planning to use another prosthetic as a shell for the next version, which will have removable fingertip and RFID tag," he wrote on his blog, ProtoBlogr.net.Half of Mr Jalava's left ring finger had to be amputated last summer after he crashed into a deer while riding his motorbike near Helsinki.He says he was inspired to create the unique storage device when doctors treating him joked that he should have a USB "finger drive" after finding out that he was a software developer. More is apparently available on the inventor's blog, but it keeps timing out for me.BBC story

Roomba mapping and quadriplegic assistive device

Hello,I am a high school student in the San Francisco bay area. After attending Maker fair this past weekend and talking to the instructables staff, i am going to take on one of your challenges and developing a roomba mapping platform, and much more. Because i am still a student, i don't have the funding to purchase my own roomba, so this is my application for the scholarship. I have attended many lectures that have been made by the Stanford DARPA team, i would like to take some of their ideas and apply it to the roomba platform. My roomba will be able to map it's surrounding, where it will then process that information, creating an optimum route. I will also utilize complete use of all the sensors that are provided so you can keep track of everything that is going on. Mapping will be one feature, there are plenty more. A nice control system for your roomba will be made so you can access everything you need to know about battery life, run time, dirt picked up, etc....in a nice GUI layout. RSS feed can also be sent to your laptop or cell phone so you know what exactly is happening with your roomba. And because this platform will be used very often to guard my precious projects, i will throw on a wi-fi video camera and control system. This will enable me to control the roomba over the internet to scout around and see what my dog is up to. The video feed will also be told to record one pass around the entire house, if anything abnormal appears (chair knocked over, loud nosies, etc.)I am also a member of this years Palo Alto High School Lemelson-MIT invent team. Our project is to create an assistive device for quadriplegics so that they can control their world using countless lase r activated household items. Our quadriplegics friend Henry Evans said that it would be amazing to be able to control a roomba that drives around and plays with his dog. I will make it my personal goal to create a platform which henry can use to control this roomba using the assistive technology our team is developing. (http://robotics.paly.net/)There are plenty of other things i would like to add on if i have the time. The main goal is to make the roomba map it's surroundings, and be controllable by our friend Henry.I have so many more ideas i would like to add on to this if i have the time, and i ensure you that i am very capable to complete these goals by the required time frame. I'm very excited to take on this project, and i believe that with your help i can really do something amazing here that can be appreciated by the entire robotic community.--Daniel FukubaPalo Alto High School

How to Identify homemade USB device connected to computer by passing some identification tag?

I'm planning on developing several different USB devices that will be operated by a Visual Basic 6 program I am writing.  I want to be able to identify the USB device plugged into the computer the same way a program knows when you have just plugged in a USB drive or webcam.  Is there some simple cheap way that I can wire in a circuit that will pass an identification tag so my program can identify which USB device has been connected?  There are certain criteria.  The parts must be cheaper than a usb flash stick...otherwise I'd just disassemble a flash stick and load a program to it to automatically run telling the usb ID.  I'd rather not do this simply because I'd rather not have to take apart several usb flash drives which can get expensive.  This eliminates Arduo and other costly circuit boards.  The parts when assembled need to be smaller than  a usb flash drive.  I just want to pass some ID serial number to the usb port that I can than pick up with my program so it knows that device has just been plugged in.  Any suggestions?

How to view corrupt zipped files? Answered

The problem is that I need to recover a zipped file from a corrupted hard drive. The hard drive is NOT physically damaged, only inaccessible due to the current state: I accidentally, began ghost imaging and completed about 10% of the initial process before I canceled it. So now the system won't boot. I get a single flashing cursor in the top left corner of the screen. If I connect the hard drive to a SATA-to-USB adapter and connect it to my Windows XP computer it will show that the 'Mass Storage Device' is found and installed. But I can't see the device in My Computer or Disk Management. What I think needs to be done is have the device (connected via USB) mounted so that I can use a file recovery program to scan the drive for files. Does anyone have any ideas? I know I can complete the reimage and then try to recover the file but its about 2.6 GB in size and I have a feeling that no programs will be able to successfully recover the whole file. I would like to recover the file without reimaging the drive because chances of the files being overwritten are much greater if the image completes.

Not sure if this has been created or could be created with the right minds and resources.  thank you for any assistance!

Build a 3v Relay Module

Would love a 3v relay module that can be drive by PIRs that output 3v signal.  Thought I finally found what I needed on Ebay, but discovered this is a bogus product that actually needs 5v to be driven.  http://www.ebay.com/itm/5PCS-3V-3-3V-Relay-High-Level-Driver-Module-optocouple-Relay-Module-for-Arduino-/331413255692?hash=item4d29c4f60c:g:6koAAOSwfcVUDuEJ Buyer Beware. Advertised relay PCB as 3v relay. While the relay on the board may trigger independently with only 3 volts, the circuitry of the board demands a higher voltage to trigger the relay. Relay PCB has a EL817 opto-coupler for the input signal, it requires a 5V drive voltage on the Input in order to drive the onboard transistor which controls the relay coil current. With only a 3v drive, there is insufficient current to drive the opto and transistor. The module that the relay is mounted to is falsely advertised as 3.0V because the components on the board need more than 3 volts. In order to drive this relay with a 3v signal device, voltage level shifting needs to take place between 3v device and relay PCB.

120 GB Xbox 360 Drive, but no high-speed internet. What to do with it?

I got an Xbox 360 Elite for Christmas. It comes with a big-ass 120 GB hard drive, and it already has some demos and videos that came with it, but you can't copy music, videos, etc. onto the drive from USB devices, and I don't have high-speed internet, so I can't download anything onto it. What can I put on it from local sources, then? I mean actually putting stuff onto it, not streaming stuff from my PC.

Is Call of Duty 2 for PC working right?

I have Call of Duty 2 (or COD2) for PC. I've had it running fine on my computer before. Then I got a virus and then had to run it again, which is this time. I put it into my disk drive...nothing happened. I went to device manager and it said that my two CD drives were not working properly. I uninstalled them and reinstalled them. I restarted my computer, put it in and nothing happened. When i go "My Computer" it says that the disk drive is empty. I have Windows XP.

My Arduino Uno is not showing up as a USB port!!! Please Help!

I am currently trying to convert my old shitty keyboard into a MIDI controller and have everything hooked up to a breadboard and Arduino Uno but the Arduino will not show up as 'USB Serial Port" as the website says it will. It is showing up in the device manager under "Ports" named "Arduino Uno (COM4)' and I am able to program it to run the blink program successfully, but it just is not showing up as a USB device in order to use it as a MIDI device. The drivers seem to have all been installed, and the usb cable is working perfectly. Also when it is plugged in and out of the computer, the computer will make the USB sound but no new USB drive will appear. Please Help someone!!!! This keyboard is driving me nuts!!!
