Aiptek 1.3M SD Camera Switch

[DenverDave]

This is my version of a switch for the Aiptek 1.3M SD camera. Attached is the schematic.

This is the connection diagram for the switch.

The completed switch can be bought for $8.00 at www.ziyaelectronics.com . The hex file and code for the switch is supplied below.

Attached is the code for those who would like to modify it for other cameras.

Thank you for post. This was my next DIY project.

Question? Where do you plug-in the 5v for the camera?

Do you plug-in the 5v at the USB connector or have found better place on the camera board?

Thanks

Martin;)

Dave:

Many thanks for your information. I have been learning how to program the 12F629/675 with some help from more experienced programmers. This might be of interest.

does the switch come preprogrammed?

Looks good.

May I ask why you have both the USB and 3.3V connections?

I don't see why both would be needed, I use only 5V out to the USB and power the PIC from that, why are you powering the PIC from 3.3V instead of the 5V from the BEC?




Good luck with your business! Looks like you have nice stuff.

The wires on the left side of the board go to the receiver. It is just a standard servo connector. The camera receives it's power from the receiver thereby it will not go into the autoshut off mode.

The 3.3 V supply from the camera is used to power the pic because the pic is only rated at 5.5 v max. It is very sensitive to over voltage damage. With it being powered from the camera supply, the pic is protected from any supply voltage problems.

The pic goes into sleep mode if the usb power is off or there are no pulses detected from the receiver. This reduces the power used by the pic to a couple of microamps.

Perhaps the question was misunderstood.

Do I have to program the PIC if I buy the switch or does it come preprogrammed?

[DenverDave]

The pic is programmed and all that is required is to solder the board to the camera. Mounting the switch is very simple. Just use double sided tape to attach it to the battery holder.

Ok I'll buy one and give it a try....

PayPal on the WAY!

Thanks

Dave,

Thank you for the clarification...

I thought you had to get a 3.3v supply(step-down regulator) to power the camera.

I just bought one!!
Some questions though:
How do ship? First Class right?
When do you ship?
Does the camera still need a battery now?
And also can I just plug it into my rudder channel and then when I move the rudder stick to the right a picture will be taken?
