VGA to USB power!

Ok, so after a few years and some data recovery, I found the original article, just not all the pics.
Enjoy the repost.


This INSTRUCTABLE came into being because of the new craze of NETBOOKS.

These small laptops have only 3 or less USB ports which is fine for some people, but for others that want to use an external Mouse, Keyboard, or just want to charge your MP3 player, cellphone or even to power a power hungry peripheral like a USB hub or external slimline DVD Burner.

This also works on Desktop systems as well!

Also, why take up a much-needed USB port for your USB novelty item? (drink warmer/cooler, lights, fans, etc...)

Step 1 Parts

step 1: Parts
We need a male to male VGA gender changer and a female plug from any old USB extension cable.

"If an instructable warrants being patented for a possible mass produced product" ... then it's NOT an Instructable anymore! It's just an advertisement.

FYI, prior public disclosure means it can't be patented. That is, unless you filed an application before publishing on this website.

[physics_dude]

Do you think you could explain your experience of patenting and developing your “product”. I’m a young inventor who likes to build stuff but some things I made I would like or would have liked patented and sold.

FYI, you didn't need to pull this. Instructables allows you to protect your work with a Creative Commons license.

I built something like this, using a ground and +5V from pin 9. The voltage before hooking anything up is +5.01V, but while pulling 120mA from it, goes to +4.60V to + +4.70V ... is this safe?

[gmgfarrand]

What device are you connecting?

[gmgfarrand]

As long as the device you are connecting is in spec of 5V you will be fine. I tested the adapter by plugging in 3 devices at the same time (Dell AXIM X51V, Creative Labs ZEN MP3 Player, and a MIO GPS) It charged all 3 devices. Just keep your power demands reasonable and only use for ONE device.

[dcork]

By "in spec of 5V" you mean it should be a 5V device, yes? It is so I am okay there. What I really wanted to know is, is that safe for the laptop to have the voltage there only 4.6V?

[gmgfarrand]

Yes. Some laptops only push out 3V. USB ports USUALLY range between 3-5 Volts.

[dcork]

Well, with nothing connected, the VGA pushes 5V. With a device connected, it pushes only 4.6V? So this is safe? Doesn't that mean that the device is drawing more than the VGA port's +5V line can handle, causing a voltage drop?

[kraM]

it would probly be super getto if i tryed but im wondering how long it would take to make something like this, got to find some parts though. nice work even though all i get to see is a pic of the finished product.

[kraulin]

how many milliamps does it provide?

[kraulin]

I did some looking and that external burner only works on 3 models of laptops made by Lenovo. So, from that maybe we can assume it's more than 500mA?

[gmgfarrand]

?? That burner works with every PC/Laptop that has a USB port. Hooked to a PC or laptop, it averages around 100MAH draw while burning a DVD.

[alex-sharetskiy]

that's what i'd like to know!

[ggiihh1]

How would you make one that plugs into the usb 2.0 port an has a female port attached? same thing with a male instead of female usb connector?

[gmgfarrand]

Why would you want to? This is for POWER only, either to power a device or to provide supplemental power in the case of using a USB "Y" adapter.

[ggiihh1]

Let me rephrase my question, How would I attach a male usb to a female vga so I could plug a monitor into the usb port?

[gmgfarrand]

You wouldn't... They make a USB to VGA adapter that will allow you to use a second monitor, but they are large and I haven't seen one that worked really well.

[ggiihh1]

hmm... so all my parts laying around wouldn't cut it?

[gmgfarrand]

Nope...

[Yerboogieman]

How would i blow out my graphics card without it being noticed that it was tampered with so i can get a new, better one.

[gmgfarrand]

Ummm.... You wouldn't. How you kill your notebook is up to you. Be creative, and make sure you take pictures!!! Sheesh.....

[Yerboogieman]

My laptop weighs to much to be a notebook, but, my graphics card sucks, and messes up when i play games. also, my laptop has a ATI Radeon 3850, but crap for ram.

[FatBoiCindy]

will this work for adding another moniter to a desktop useing usb?

[gmgfarrand]

No, POWER only.

[mattameo213]

WHERE DID YOU GET A BACKTRACK LAPTOP?????? *Mad Respect*

[gmgfarrand]

Got the skin for the lid specially made from a local company.

[mattameo213]

Is it running Backtrack? Is that an Acer Aspire One?

[Solifluktion]

No, it's an Asus EEE 900/901.

[gmgfarrand]

No.. It's an Asus EEEPC 1000H

[mattameo213]

Awesome. I have an eee 701. What OS do you have?

[Joe Martin]

If you read the comments, He's triple booting xp, ubuntu and bt Joe P.s Lolz @solifluktion

[Solifluktion]

I've never seen the 1000H before I just looked at the Display and decided that it has to be the 900 because it's definately not the 701 ;)
Looks pretty small for 10

[gmgfarrand]

It looks even weirder when I have my WiFi Sniffing goodies attached. I modded a pigtail into the left hinge, and I either connect my CANTENNA to it or to my ALFA high power USB Adapter 500mW. Or I just add an Antenna to the external connector that goes to my internal card, and run the USB WiFi at the same time... I'll have to post pics sometime.

[camintmier]

Note: On some older VGA connections, pin 9 isn't connected at all, so this might not work on your old 486.

See http://pinouts.ru/Video/VGA15_pinout.shtml for more info.

It might be easier to just use an externally powered usb hub.

[lllalllo]

It will not work on black and white cards. (the pins are used on color cards to detect the monitor)
