If one were to install the chip, let's say, upside down; could that potentially damage the chip?

It seems that the Eagle Eye board does not want to come out of walk test. At first I though I may have applied to much heat soldering the PIR onto the board, which could have caused it to malfunction and continuously send trigger signals.

What I'm getting is a constant blinking of the led after the program goes through turning the cam on and off. When I ran the program through the editor everything ran fine.

Could I test the input pin on the Picaxe to see if the signal is being sent even without motion - false trigger?

I should also ask if there is a way to determine which is giving a bad signal, maybe help eliminate one from being the issue?

No idea here but just wondering a couple things as have never used the board. I know the aio among others has a little tab out of one side so it can be positioned as the diagram on the board (ones I'm aware of have 3 legs so don't see how can install them wrong?). Are you talking about it in a build and turned on or just the board seperate? Reason asking is I've had the camera hack actually have a bad solder spot, loose wire, etc. that has caused the led to blink constantly.
Probably all the previous has no bearing on this.

The PIR "should" be positioned correctly [smile] .........lol, the board does have that marking on it so it should be okay. I've tested both with the cam hooked up and without so that's not it. What I did do was install the op amp chip upside down, and also had the PIR flush with the board, when it was all together I didn't like how close it was to another solder point, out of fear of short circuit I melted the solder leg by leg and lifted the PIR from the face of the board. In doing that I may have applied too much heat. [frown]

Yes you can damage the op amp when put backwards.  They will get hot because I have ruined one this way.  What is the voltage to the control board.  Also make sure the pir pot is not all the way up.  If the pir pot is to high it will not go out of walk through.

The program should turn on the camera when in walk through.  So when you turn on the board the camera should come on.  If not you have s issue with the power mosfet.

The supply voltage was around 4.5V, the camera may have a timeout feature that would that would shut it down after a certain length of time. I'll have to change that.

I did notice that when I first powered on the board, with the chip backwards, the flux started to sizzle after a while.....that may just be the issue.

If you put the opamp in backwards and applied power to it you definately destroyed the opamp.  That is your problem!!!!  The middle pin on the left side is ground and the middle pin on the right side is power.  If you installed it backwards you basically ran the power through the chip BACKWARDS....CHIP DESTROYED!!!!

Thanks everyone, we have now confirmed I'm an idiot [smile]

All jokes aside, I notice that the TS27L4IN is no longer available. What are the critical attributes of this chip. I have noticed some replacements that have different surge values as well as a tad higher frequencies. (0.04/0.05 and 100mghz/110mghz)

Any ideas?

I would go with 6v.   Depends on which regulator you are using.  A 5v regulator will not work with 4.5v.

This is the board and parts I had received from you(Charles) just before Christmas, it would be the regulator you had supplied so I'm really not sure. I will have to re-test using a 6V source, but it sounds like the chip is the issue.

Fun, fun, fun.

That is why I questioned this.  That is a 5v regulator.  This can cause the board not to go out of the walk test.

I am confused now? My Critter Getter Micro runs on a 5v LDO voltage regulator and that doesn't prevent it from exiting walk test mode. I used the tsl27l4ain Opamp for a short time with decent detection before switching to the mcp6044isl which is a much better more accurate Opamp and is what I currently use but it is only rated for 5.5v and the reason you guys run 6v on the aio is slave power I am assuming.

Actually it doesn`t do what people think.  So you have no issue with using a 5v ldo with a 4.5v power supply.  The 4.5v is below the 5v output.  This causes instability in the regulator.

I have used a 3.3v regulator and 4v regulator with the Eagle Eye board.

The Critter Getter Micro is ran by a 9v battery and I use the 5v regulator on it. The Critter Getter PRO is ran by 3aaa and it does not have a voltage regulator on it at all. The new picaxe chips are stable from 5.5 v down to 3v...

Yes you can use a 9v battery with this version of the Eagle Eye.  But if you are going to connect a 6v camera to it then that would be bad.  That would put 9v to the camera charge circuit.  Remember you can use the Eagle Eye to charge the batteries the camera.
