Digital shutter release

The stock Gigapan Epic 100 uses a servo to press the camera's shutter button. The disadvantages of using the servo are:

  • It shakes the camera
  • It draws significant power as it presses down on the button
  • You have more flexibility in positioning the camera because the shutter servo doesn't have to reach the shutter button

The Epic 100 has an optional setting under the Advanced Settings that allows an electronic shutter release instead of the shutter servo:

Options > Expert Options > Shutter Mode = Remote Port

Connector to circuit board to replace shutter servo from Tower Hobbies: Hitec Servo Wire Male S Connectors

(Connect Y to shutter, B to shutter ground)

Wired remote shutter release ordered from Amazon: "Opteka Remote Shutter Release"

  • Connections for Opteka wired remote:

  • Received both Hitec and Opteka connectors: made wired remote. Note that connecting just "Shutter Full Press" and "Shutter Ground" would not fire shutter - you have to tie both "Shutter Full Press" and "Shutter Half Press" (Opteka white and yellow) to the Gigapan yellow wire to get the shutter to fire.

  • Final Olympus remote control cable:

Cable works fine, the only change I made was to bend the connector to stay closer to the gigapan body so that it would not interfere with the camera movements. -- JeffPelz - 14 Sep 2009

Pivot Support

  • One problem with the current Gigapan unit (even the Epic 100) is that it supports the entire weight of the camera and lens from one side. This is fine for small cameras, but when we install a DSLR with a large, relatively heavy lens (e.g., 70-300mm or 12-60mm), the weight can cause two problems.

    • The first is that the camera can cause the camera cradle to 'sag,' and the amount of sag will vary depending on the vertical angle of the shot: angles closer to horizontal will show the most variation and angles closer to vertical will show the least.

    • The second is that the extra weight suspended from one side may cause extra vibration because of the relatively long moment arm and the suspended weight.

  • By moving the camera back, it is possible to shift the center of balance of the camera/lens system to the axis of rotation of the Gigapan, so very little torque is required to rotate the camera, but this doesn't address the sag issue. To try to remedy this, I designed a pivot to support the opposite end of the camera cradle.

  • Side view of support pivot with camera support removed to show alignment of pivot support and servo axis:

  • To open the battery compartment, the camera tray has to be rotated down so that it is out of the way of the pivot support.:

Camera bracket

  • Originally I made an extension that shifted the entire camera cradle back. This was necessary because we were using the shutter servo to press the shutter button, so it had to stay in the standard position. Now that we are using an electronic shutter release, we have more flexibility in camera positioning. I extended the slots in the camera bracket plate so that the camera can be shifted further back on the camera cradle.

  • Extended slots cut in camera bracket plate:

  • With the new bracket slots, the camera/lens can be balanced correctly without having to attach the extender plate to the vertical servo.

Alternative Power Supplies

  • The internal battery pack is convenient, but it doesn't allow the Gigapan to collect a large number of images before it needs to be replaced. The goal is to allow a larger capacity power pack, and/or to allow simple replacement of the power pack without disturbing the Gigapan head.

The Anderson "!PowerPole" connector is a polarized, stable, low-resistance connector. (Spec sheet in the attachments list 9/15/09).

  • To bring the power to the Gigapan head, a generic power cable has the Gigapan power connector at one end and a PowerPole connector at the other end, polarized with red=+. The cable is ~2m long, and has extra strain relief at the Gigapan end because one of the power pins was broken and repaired. Once we get replacement pins I will shorten the cable a bit and put on new a connector.

  • The first power pack is a D-cell pack:

Panoramas

  • Field test at RIT: ~140 images, 8 rows of images each with a 10 FOV. This has been downsized quite a bit from the original!
