5 Volt 5 Pin Relays.

[xman]

Finally found and ordered some relays so I can mod the DX IR receivers.

Now I can replace the receiver board's 24 volt relay with one of these and the conversion from 240 volt to 5 volt of the board is complete.
This is nearly what the board looked like before hacking-

I have taken nearly every part off the board, the 24 volt relay, the diodes, the red cap, the large cap and the 5 volt regulator. I feed a 5 volt supply in where the regulator was from the 5 volt standby supply on a 1.6 xbox power supply and change the 24 volt relay for one of the 5 volt ones and now the whole receiver works on 5 volts. The other problem is the board is a latching circuit and to get around this and turn it to a momentary devise to pulse the Xbox on or off, I connect the Xboxes power switch across the relay terminals. The 2 outside terminals of the relay's switch are connected to the Xbox's open switch terminal so when the relay is in either position, on or off, it does nothing however, when the relay changes state, the switching relay terminal which is connected to the Xboxes "other" switch wire is also connected to ground via a 20k resistor. What this does is ground the Xbox's switch wire whenever the relay changes state. The 20k resistor is there to prevent a short and only supply a ground signal whilst the relay changes state. I'll do a complete "How To" with pics when I have the relays and have tested the circuit. The best part about this mod is the receiver is a "learning IR receiver" so that means it can be tuned to work on any button on just about any IR remote. Once I have the 5 volt 1.6 version working, I'll have a look at how to get it working on the other Xbox versions.

Slick work X, so this is a like a homemade X3IR yeah?

Yer that's correct Nex. In keeping with the Xbox modding theme of "It's gotta be cheap". I really like these because at $4.30 and the ability to tune to any IR remote and they can also have two codes to activate them and these can be on totally different remotes and different buttons. This means you could use a MS remote unused button and a unused button on your T.V. brands remote.

you gonna cook up a guide for u xman? im likin 5 bucks

Actually starting to worry how long these relays and other parts I've ordered are taking. Some, like the alarm module I ordered are quite pricy. An X3IR is a good description I guess but you can use these things to control anything really especially at this price but the best feature is to be able to use any of your existing IR remotes to control them. I will do a "How To" when I have it running ,tested and installed.

Relays arrived today....
