Motorized half automatic pano head
by Fx_CAD, published
Untested project for the MakerBot Giveaway contest. Iâ€™ve got no clue about how sturdy MakerBot printed parts are, this means that I donâ€™t know if the parts I designed are thick enough to support the weight of the camera and steppers. Iâ€™m maybe plain wrong ! However, parts size have been carefully designed to fit into Makerbotâ€™s build envelope. The only overhangs are holes, therefore the parts should be printable on a MakerBot (At least, I hope !). STL parts have been checked with Netfabb and are manifold EDIT:I reuploaded the STL parts. They are now oriented in build direction
This half automatic pano head has been designed to take pictures using a Canon Powershot A560 compact digital camera. The purpose is to shoot panoramas without getting into the risk of forgetting to take THE PICTURE absolutely needed to get a complete panorama (when you donâ€™t have got a wide angle lens, you need to take a lot of pictures!)... The head moves left/right and up/down. Two NEMA 17 sized stepper motors are controlled by an Arduino (or compatible clone) using two Sparkfun\'s Easydriver. The shutting mecanism will be controlled by Arduino.
The Canon Powershotâ€™s normally donâ€™t have remote shutting capabilities. Fortunately, a great open source software package can add a lot of functionalities to these cameras: CHDK. It adds remote shutting by detecting when voltage is applied on camera usb port.
This head has to be mounted on a standard tripod.
Function: When pressing the start/stop button, the camera will take a picture (or more, if CHDK â€œbracketing in continuous modeâ€ is checked â€“ needed for HDR), then moves upward, takes a picture,â€¦ , then moves left,then moves downwards, takes a picture, â€¦ ,and it does the same column after column. When the necessary pictures have been taken, the photograph has to press the start/stop button. After, the reset button has to be pressed to put the pano head back in starting position (only horizontal axis needs to be moved).
Advantages of this design:
-No need to carry a notebook to control this head.
-Simple to use.
drawbacks of this design:
- the row/column intervals and time between moves can only be changed by editing the arduino sketch.
- No care taken about â€œNo-parallax pointâ€ for now.
