Turning Infrared into Radio Control?

Hi,

I have a simple toy robot that is controlled by an infra red remote that I would like to transform into radio controlled.

I think the easiest method (least alterations) to do this is to fit an opto coupler setup to both the remote and the robot. In this case an infrared diode receiver or transmitter and a bit of cardboard tube with the signal via a radio transmitter.

I can not remake the controller as the data it transmits is very specific.

Not being very up on electronics I need to find a simple radio receiver \\ transmitter circuit that will allow this.

I imagine that the IR transmitter receiver diodes would simply replace the speaker or mic if this was an audio circuit.

Is remote type infrared transmission a series of pulses rather than frequency or amplitude modulation?

I only need enough power to transmit room to room. About 10 meters or so.

Anyone know of any simple circuits I could have a go at building or modifying a kit? Any projects online?

For radio transmission I am in the UK so guess certain frequencies wouldn't be legal.

What about just moding one of those very basic radio controlled toys?

Ideas appreciated.

Pete

** Forget the radio control conversion - waaaay too complicated.

Get yourself an Infrared Control Extender.

You can get remote IR extenders. They do exactly what you want except that you may have to butcher the TX and/or RX unit to fit onto your robot and.or remote if they don't have a good view of the room already.

Cheers but radio is the way I wish to go.

I have seen a number of IR to IR extender cicuits that would cost less than $2 to build but the are not suitable as I want a strong control.

Even flooded IR has a line of site problem..

Cheers anyway.

I've seen a few RF IR booster units. They are rediculous prices for what must be a simple circuit. Many have multi IR channels though.

In my ignorance I can't see how such a booster would be hard to make if I can find a radio circuit with a sufficiently clean signal.

From reading most IR has a carrier of 36-40KHz..

Maybe the robot NGs have more experience with this..

I'll keep looking but thanks for the suggestion.

OK so you are the type that sits behind a keyboard and feels powerful enough to be nasty and agressive. Probably because you don't in real life.

Very troll like behaiviour that makes it pointless to listen to anything you have to say.

Well there are plenty on the market but then you seem to feel superior to the manufacturers and the masses that buy these devices for some reason.

Just because your advise was not of any use to me and I choose to continue in my search you are this aggressive towards me. Are you just pent up or something or behind a WHISKEY keyboard ;(

OK Phil so you are the type that sits behind a keyboard and feels powerful enough to be nasty. Probably because you don't in real life.

After looking your posting history on usenet and various forums you seem to do this sort of aggressive shit all the time.

I suspect you respond with lame replies and when told that that was not the theme of the post you just like masterbating off on your keyboard.

I could never see the reason for such aggressive behavior but maybe it actually is too much alcohol, a weak and feeble personality or just that you only have this avenue to express your self.

maybe you should join the hitler fascists down in the local forums.. they have exactly the same posting manner as you.

What a sad person you are "Phil Allison"... or whatever your name is.......

On the other-hand, Phil knows electronics, but you haven't a clue.

How can you determine that a circuit will be simple? You can't.

Most people aren't willing to try telling people with your attitude anything.

Don Bowey

So your example of a non-simple circuit is?

The attitude was not a hostile piece of verbage that Phil presents that you seem to ignore. What attitude is there to ask for examples?

If you don't have any simple or otherwise then why reply.

Thousands of posts by Phil and 30% are trollish, rude and agressive. If you think that is the judge by which someones knowlledge is valuable poor you.

He had nothing to offer. Sadly neither do you except to defend his right to be a troll!

After some research and for the benefit of anyone else looking for such a project - but that may be put off by the utter negativity of some arrogant troll responding to this post - here are some examples of what was simply required:

Basic Project Kit:

--------------------------

The Ramsey kit uses only a few components on a single sided home reproducible board with a simplicity level of near beginner.

The most non basic component examples are: Semiconductors

1 IR Sensor Module [U1] 1 1N4000 series rectifier diode (black with white band) [D2] -Note that 1N4000-1N4007 diodes may used. 2 2N3904 NPN transistors (marked 2N3904) [Q3,4] 2 2SC2498 UHF NPN transistors (marked C2498 or C2570) [Q1,2] 1 78L05 5V voltage regulator (marked LM78L05ACZ ) [VR1] 1 Large Green LED [D1] Miscellaneous Components 1 33 nH 4-turn coil [L1] 1 433.42 MHz saw resonator (TO-39 Metal 3-pin case) [X1]

Nothing above is oh so complex certainly not 'rocket science'..

There may also be other circuits and projects out there but as I have now found a solution that will cost me about $8 and a little effort I have stopped looking.

= There are always sad people who need to put you down - to feel big themselves - by trying to limit your options and horizon in their reply to a simple request. Ignore them and keep on looking.

Nope. I asked for info not some troll being aggressive.

Utter ignorance on your part. I have a life beyond this place in which I have quite a strong socialism in a different field. I often give advice but never the trollish stuff you seem to be defending.

I asked for some info that was all. The troll is well known. I responded to that. The message has now been taken over by some alternative objective on your parts not mine.

Stop and take out the troll and reactions to him and the thread does not have anything you are suggesting in it.

There is no demand for a "strong signal". You have taken the words out of context. Strong signal could simply mean having integrity in the distance required. This was room to room of about 100 meters.

As to legality that has nothing to do with this. it was simply information that may lead to one suggestion rather than another. i have a number of wireless devices around the house. All are legal. I haven't failed in that at all.

You seem to be making weak references. If you have examples of complex circuits that meet these needs and show that the task is too complex for someone with a soldering iron then give me the links and I will happily go and look at them....

... but something tells me you don't have info on this - do you?

John. If you feel that the trolls responses listed here:

| ** What a fool. | Tried strong beer. | ** So do human eyes - you f****ng idiot. | ** As if this ignorant f****ng moron would have a bloody clue. | Not even grammatical. | Go Fuck Yourself. | ........ Phil

are really worthy of your defense then that is just sad.

You take your own advice. After all it is you that is responding because you are somehow 'perturbed..

As to the rest of your stuff about leg work.. I've done quite a lot. Sadly the types of responses given by a few here just detracts from any benefits that could be gained from a newsgroup.

I asked for info on moding IR-RF-IR devices or simple kits or circuits.

I got a load of bullshit and crap.

I have posted some of the info I found despite you and the trolls that shows that moding IR-RF-IR devices or building simple kits or circuits was not the enormous amount of effort you all claim it to be.

Probably because you few seem to have some form of superiority complex that stop you from behaving like normal people do in the real world.

In the end I now have a few very simple solutions lined up so whatever you say is just pointless...
