Electronics stupid idea could make millions

i dont know if any body else has thought of this but what a about a wireless usb port ou would need a dongle to send and recive info from a usb port and a transmitter/reciver with power suply/batterys whatever simple concept could come in use making wired devices wireless

 

Exists. it's called Bluetooth.

 

and closely to your idea, there is a thread here on bit started by a guy that wanted to make a wireless mose/keyboard that lead to the same idea

 

I assume he meant being able to use current USB devices as wireless by having two transceiver modules, one in the computer's USB port and one connected to the device.

Technically it's possible, but you'd need some fairly complex electronics to do it without horrendous amounts of data loss.

 

blue tooth is nice but it doesnt have half the devices as usb im talking about wireless usb like scanners joysticks usb thumb drives maby set it up where you have all your pc in one room with your tv/ moniter in another with a wireless usb port you could do computing in another part of the house withn out moving the pc

 

I'm preatty sure it's possable, but the only problem is power. A consistant 5v line would be hard to supply, two AA batteries only give off 3v. So you'd end up with a honkingly heavy battery pack, or a seperate plug that goes into the wall (though, if you are pluging in a monitor, joystick, mouse, or something like that it wouldn't be much of a problem). Theres gotta be a way to do this! Come on, lets brain storm, see if we can't do a mod to something that'll give this same effect, maybe start small, like sending a small partial stream via a cordless device (like a cordless phone, or something like that).

 

what about those wireless mice/keyboards that don't use bluetooth?

 

he s very right. i never looked at it from that perspective. technically is very possible...even easy...but just stop and think for a sec, that every packet that goes over the air doesn t really have to make it to the destination...so, you would have very high data loss which you have to make up for. Also, speed might be an issue with the simple variant.

 

I've seen a dongle that allows you to connect any usb device to it, which will then enable it to be used with a compatable bluetooth reciever. I think it was in the CPC computer specials magazine.

 

You'd be very lucky to even get 3V from AA batteries to be honest. When you take into account things like the internal resistance of the cells, plus the fact that the EMF drops as the cell runs down it would be an absolute bugger to do.

That would mean about the only way to use batteries would be to use a voltage regulator which is adding to the electronics required even more.

Sounds interesting, but the level of compatibility will likely be fairly low. I've seen those Bluetooth printer adapters that plug into a printer's standard centronics connector and I know they can be pretty finnicky when it comes to actually working well.

 

i wouldnt mind a litle plug that goes in to the wall just some thing i can plug a usb device in to in another room with out a long usb cable (to expensive but i think there is a few camcorder batteries or something like that maby set it up some way to were it can go throug ethernet i know there something like that some were)

(i think the idea is great and every thing but like with data loss witch im sure some one can get around to doing it im shure if thay can make micro chips smaller than a hair witch im sure they can it possible

 

That exists too. It's called Wifi.

 

im sorry maby i said it wrong

what im talking about is a wireless usb port


NOT:
bluetooth
wifi
802.11b



baby it could use some of that type of technology but im talking about wirles usb port that will work with any usb device

 

What USB devices would there really be an advantage to being wireless? It's obviously a little more convinient but what would you really want in another room?!

 

OK, I'm sure I'll really get on your tits now, but what I was trying to say is that there already are solutions to resolve the issues you're trying to address with wireless USB.

Although I recognise the elegance of having just one interface standard in both wired and wireless version, I don't think anyone is going to try and resolve the considerable technical problems involved to come up with something that is already addressed by current standards that only just now have become established and affordable.

A few Bluetooth integrated cameras and printers already exist, and I can see a future for Bluetooth keyboards/mice, joysticks etc.
I certaintly foresee Wifi getting smaller and sleeker, and in the near future being able to just place your iPod-style portable 2.5" HDD chrome lozenge on your desktop as it automatically detects and hooks up with the wireless network access point.

Wireless Thumb drives, Bluetooth or not, are a very sexy idea, but where would it get the juice required to operate (currently it gets 5V over the USB port)? All I can think of is a transponder-like induction coil setup, but that would require physical proximity-- you might as well just plug the thing in.

 

Well Nexxo, some nice ideas but a couple of things to point out. Firstly, MS already have a Bluetooth keyboard and mouse combo. They suffer from the usual problems that wireless keyboards/mice have as well as the Bluetooth dongle supplied not working with anything else (this is from a few reviews I've read not personal experience). That coupled with there being no official Bluetooth device profile for keyboards or mice mean that really it's just a proprietary solution with Bluetooth used to get a few more sales.

Wireless thumbdrives would be very nice indeed, meaning that you could basically have it on a keyring so you wouldn't even need to remember to take it around with you, just keep it with the stuff you always have with you and you're effectively storing it in yourself !

Power for this could come from Splashpower once it finally turns into a commercial product. I won't pretend to know how it works exactly, but apparently it's a pad which is connected to a power supply, then you just chuck your phone/PDA/MP3 etc onto it and it'll induce a charge in a tiny chip inside them to recharge their batteries wirelessly.

 

they could simply put a battery in the thumb drive as i don t think it requiers very much juice to read/write, and a button just to let it know when to go into operation mode

 

I know the MS Bluetooth keyboard/mouse combo exists. Logitech now also do one. I also know that they're far from perfect: they only operate in Windows, not pure DOS (as opposed to DOS in a Windows environment) so if your OS crashes or you want to edit the BIOS you're stuffed; battery power consumption is prohibitive, and the MS product has no compatibility with other Bluetooth devices.

This is why I said I see a future for Bluetooth keyboards/mice. They're not really a viable solution yet. But they will be.

Splashpower is basically the induction principle I described earlier (pioneered by a.o. Phillips). But as I said: if you have to put the drive on a pad, you may as well plug it in. Wireless won't have a point unless you don't have to take it out of your pocket.

I know where at_b is going: if a car remote keyfob can operate on a button cell battery (for years even), then why not a thumbdrive? Well, a keyfob will only emit a microburst of data each time you push the button. That is not the same as the data traffic between a PC and a thumbdrive. Although as data speeds increase, this would become more of a possibility. Hey, we once thought that wireless optical mice were difficult to realise!

 

lol...i was going to...sleep... but, here s my 2 pence

the ericsson bluetooth headset adapter, with rechargeble batteries, will work after you tell it to(press the button) and can withstand some time talking through it, not sure exactly how much, but i would guess enough...so a thumbdrive on that same technology should work fairly well, with the disadvantage that you d have to recharge it every few uses...oh...another disadvantage would be that it won t be quite thumb sized although the ericsson device is quite small...


sorry for my spelling but i m 9/10ths asleep

 

See, all this is fine and dandy, and yes, things like bluetooth and wifi are good solutions, but think of the cost of them. I've been pricing out a wireless keyboard and mouse set, and the CHEAPEST I've been able to find (super low quality, no extra features, nothing) was $100 canadian. Now, some people can afford that yes, some people have money, but I don't. And I know a lot of other people out there don't either. So what I invisioned when I first asked the question "can you make a wireless mouse/keyboard", is not "hey, I have a ton of money to throw arround, so how about some super expensive solutions?", I thinking "why not something simple, a small wireless station that has a couple plugs in it, screw the minor data loss, theres data loss in normal cables to begin with". If you have an existing keyboard and mouse you like, and don't want to give up, and they don't make a wireless keyboard and mouse set thats exactly like what you have, arn't you going to get a lilttle annoyed? Wireless componants have come down drasticly in the last few years, you can now buy 2.4ghz cordless phones for less than the price of a pizza ($20), so why is a concept this stupidly simple, being made so hard? I don't mean to condone anybody, nor say their ideas are invalid, thats the furthest thing from what I'm saying, all's I'm saying is "help us to do this". And btw, cordless phones allready have data loss control chips.


[EDIT] and btw, that wireless keyboard/mouse set was IR, not RF [/EDIT]
