Speed Passion Wireless Adapter

[tank423]

 

“Speed Passion have announced details of a future product line, which they say looks set to revolutionize both gas and electric R/C racing. Their rather criptic release states: We are proud to bring the Power of freedom, “The wireless powerâ€. “Reduction†is one of the ways to help to protect the Earth. Imagine playing with an R/C car, boat, or soft air gun without chargers, power supplies, and extra battery packs. No more worries about battery pack quality, and chasing constant small advances in battery capability and size. Saving you time and money and developing new ideas to improve your skills in order to enjoy the pure fun of R/C.

 

What product they are announcing I dont know, but the picture above shows version 1.2 of the Wireless Power prototype, which looks like a speed controller with battery inputs that has a built 2.4Ghz system, judging by the aerial. Speed Passion will release more details every month in the lead up to its 2009 release date.

 

(taken from an rc forum but it mentioned airsoft so i thought i would share with you guys)

[Magsz]

Um...yeah...

 

lol.

[freq88]

isn't april fools a month away?

[Bizurkur]

It's not a joke, wireless electricity is a possibility, and it's coming soon.

Just finished reading an article on it.

No no no no no no and no.

 

Lock this please. This is a AIRSOFT forum, thus usually we like having AIRSOFT news in our AIRSOFT section of these forums. Put this under Off-topic if anything.

Yeah, you know this can actually be utilized in airsoft, right?

[Dock trinE]

Assuming this thing does work, wouldnt it only work within a certain range? In RC it would work because the track is only so big, but in airsoft there is much more moving around.

[freq88]

if it does work then you can put the pack and "transmitter" inside a pouch on your rig or in your pack on you. So range isn't an issue.

[thartwig]

looks like it has a pretty large fan, could be troublesome if you put it in a pouch.

[amateurstuntman]

yeah, and how big will the receiver be?

And aren't you worried about microwaving your balls and sterilising yourself?

[Nox Invictus]

Well, assuming that it is as big as some are making it out to be, and assuming that it does work like it's supposed to, I'll start running a third line just to carry the sucker around.

[Bizurkur]

I am pretty sure the ability to have infinite maneuverability and never having to use PEQ again is worth a slightly heavier buttpack.

 

[Magsz]

That looks like its about the size of a PC power supply unit only a bit thinner.

 

If the fan wasnt going to get obstructed and overheat the sumbitch id say that this could be a stupidly cool invention especially when applied to airsoft.

 

Remember guys, the transponders are going to be ridiculously small, they have to be in order to work on RC cars unless this is being developed for those huge monstrosities that look like glorified go-karts.

[freq88]

if they can make this work. Someone will figure a way to make it fit onto/into one of our gear/pouch.

[DarkLite]

And when your AEG draws 20+ amps (as a stock AEG often does when starting a firing cycle) you'll then microwave yourself. Greeeeeeeeeeeeeeeeeeeat.

[shcurti]

Again echoing the rest If it works I will line up for one I would like to see a little more R/D go into it before I trust the boys around it.

1. wrong hobby - wrong forum but we all like to use things for airsoft which are not made for it

2. get free power out of the air - I have the background and can only say (no problem to make a "wireless" charger for you mobilephone but this is another topic as it is to get 0.00000XAmp out of the air too but just forget it for airsoft, if you do not like a light bow between your vest and your gun (all the field solutions are far from ready yet))

[rik]

this is super awesome.

if this becomes real for airsoft.. no more wiring problems! woo!

[MDK_Marshal]

Oh, for pity's sake.....

 

Look.

 

Wireless power is easily possible, yes, and the tech is coming through. However, I doubt it will EVER work for airsoft. The way this works is a big radio signal is beamed out. A receiver catches it, and converts the signal back to electricity.

 

There are a few MAJOR stumbling blocks with this technology, ESPECIALLY when you take into account the absurd current drains airsoft guns have - even stock marui ones.

 

One of the big ones is range. The signal strength (and as such, the power transmitted) will reduce with distance, so that when you move further away from the device, the power it's got to chuck out to reach you increases exponentially.

 

If we assume that each AEG will require about 100 Watts of power to run (10 amps * 8 volts, plus some for distance falloff), then say that we've got, maybe, 50 skirmishers playing. this thing will have to be capable of giving out 5kW in that scenario.

 

How many watts is your microwave? And how fast does that roast things if you stick them in and turn it to full power?

 

While it's hardly going to be a Maser or something similar, it's still one heck of a lot of energy to be blasting into the radio spectrum. Transmitters that work with those sort of power levels are big, bulky things with lots of dishes; not a little aerial like this has.

 

You know, I can't be arsed to rant any more. Some mod just lock this, or move it to off topic. Please.

[Shriven]

Blimey mate, calm down... as well you can see, the vast majority don't understand electricity/microwaves etc ( myself included)... so don't get all stressed out when someone finds something that is touted as being a wireless power unit and not a long range microwave.

The idea is great... however, after what you've said... not so much!

[Catman]

Witchcraft!!!!!!!!!!!

 

 

 

I've heard of this tech a few times in the past, maybe it's application would be better suited as a constant top-up charger for your battery?

[Magsz]

If this is being designed for RC cars dont those platforms use a crapton more current than an AEG?

That's just what i was thinking

 

Wireless electicity is nothing new. Legand has it that Tesla wanted to use it as a way to deliver electricity to houses and factories, but in the end they never went ahead because they thought there would be no easy way to meter how much a customer had used Really it's quite simple induction stuff but getting the transmission gubbins small enough to carry might be a problem, even if the receiver isn't

[mannerofliving]

Now if they go the fuel cell route (that is with enough power), then we may have something... example, http://www.dailytech.com/article.aspx?newsid=5130

So far, MDK seems to be the only one to have given the problems with this sufficient thought.

 

Anybody here heard of a cats-whisker radio?

 

You can build a simple radio that makes use of the power from a radio signal to actually power it.

The problem is that it'll only allow you to listen through earphones. Quietly.

The reason being that the signal you receive is tiny. Miniscule.

 

The ONLY way a system of wireless power can work reasonably is using directional antennas. That won't work for airsoft because you're moving around.

To transmit enough power to an AEG half a mile away you'd need an omnidirectional transmitter that looks like something out of Lost In Space and would cause every player on the field to glow like the kid in the Ready Brek adverts. And then drop dead from a combination of radio-burns and massive electrical damage to the brain.

 

Though MDK has the right idea, even he has underestimated the amount of power dissipation that will occur as you beam electricity through air. It would take gigawatts of power to transmit 20 amps of power to a couple of dozen AEGs over a radius of half a mile.

The way we're talking about transmitting electricity in this thread is just impossible. Can't be done.

 

There are currently experiments to use lasers to transmit electricity. Because a laser is so tightly focussed it can transmit energy over distances. Even so, the received energy is only a fraction of the energy transmitted.
