Ok, heres the score, I have an infra-red device, I won't bother saying what it is or it's purpose etc because it will just leave room for unnecessary andn ot helpful replies, the question is this, and this is more of a project than a need to hae a working remote for said device. I have a device, but i don't have the remote, it's not a common device, so finding remote codes on the net isclose to impossible. The idea I'm having is to use some sort of program (via the MCE Ir Blaster) or make a PIC circuit to somehow "brute force" the device, meaning, I want to see if i can beam IR signals at it in a brute force manner in the hope of finding the correct signals to operate the device. If it comes down to it, I can possibly test the internal circuitry, see if i can find the clock frequency of the IR system, see if i can atleast find the modulation frequency, other than that, I have nothing at present to go on. My question is, does anyone have any suggestions on ways i could start beaming semi-random IR codes at it, for example, by downlading an internet database of IR codees for different devices and beaming them at it till i get a reaction. Call it, a little bit of reverse engineering, except with hardware and not software. Any suggestions appreciated.

If the device is infrared and it originally came with a remote I would think you should be able to get a home electronics remote to work. The last time I had to program one of those things there were literally hundreds of Models of equipment listed. For each one you needed to key in a 4 digit code. That would be trial and error.

Like I said, it's not really a mainstream device, and it's by an unknown manufacturer, also, it's cheap, and the remote is cheap, so it for sure wont incorportate anything reaching the comlexity of a stanadrd remote control.

Well, If your like most of us you probably have a bunch of old remotes lying around. Won't hurt to try. You don't need to use all the buttons on the remote. I had a TV some time ago that the remote got broken. Still worked but the case was broken. The closest replacement I could find didn't replace all the original function buttons and some that were labeled for one function in fact controlled a different one. I don't know how infrared remotes work but I'm guessing it may be on pulses. That is why I suspect any remote may cause on or more of your needed functions to work.

Hehe, fortunately, I am quite aware of how a remote works, and am more than capable of making one, which is my plan to make a replacement for this device. Unfortunately however, no amount of knowledge of electronics seems to help me with a solution to finding what IR codes the device needs to receive which is the help i'm looking for. Failing that, I will simply rip out the IR detection circuitry and build my own with know modulation and codes, it requires only 5 buttons, and by the remote from a similar device I have seen, the codes should not be as complicated as a commercial product remote. After scanning the output of a remote for a similar (differnet brand) device of the same nature, it's codes were simply a repetition (with a variable number of repetitions) of the same code "fc"(hex) followed by 4 stop bytes (ff ff ff ff). Unfortunately this doesn't tell me the modulation of the remote (and of course i tried the obvious - pointing the remote at the damned thing to see if it just works, unfortunately not though.) I'm lookintg for a way now i can load a whole databse of downloaded remote codes into some program like HIP or Girder and blast them with an IR Blaster at hte device until i get a reaction.

Ok, now I feel stupid, just opened the bleedin thingu p, thought I know, I'll see what's inside and just make my own IR hardware, so, opened it up, No LDR, looked around, the whole chip for the IR detection just isn't even on the board, the space is there, no chip. Anyway, guess we found the solution, next thing is to make my own IR detection system. AMD X2 4600+ AM2 ACFrzr64 M2N32-Sli Dlx 2x 1GB Corsair XMS2 DDR2 800 NvGeforce7600GT Enrmx.

Is the IR detector on the board? Most devices use a detector in a cubish module about 3/4" on a side. The logic may be in the can.
