Not while this head is still available you should also check out the new DB3 WIFI & VISCA head here: https://www.thingiverse.com/thing:6180189

This is the Digital Bird three axis balanced pan tilt head part of the Digital bird motion control system. The head can be used on its own or as part of the wider Digital Bird Motion control system. In order to use this head you will also need to build one of the two WIFI controllers found here: https://www.thingiverse.com/thing:5329252
or
https://www.thingiverse.com/thing:4853106

The head can also be used with the Digital Bird focus/zoom motor available here: https://www.thingiverse.com/thing:5156219

As well as this balanced head you may also wish to consider the Digital Bird over the top pan Tilt available here: https://www.thingiverse.com/thing:4842363

Features:
• 360 deg of continues rotation in the pan axis and 130 deg in the Tilt axis
• Capable of lifting a Tilt payload up to 3.5KG
• Automated mount/dismount via two buttons on the control panel
• Sony NP style batteries with 7.5v external power port
• 3rd axis support for Focus motor through RJ45 port
• Full feature interface though Digital Bird compact WIFI remote or PTZ remote
• OLED battery monitor and PTZ slave ID
• Battery lock for Inverted mounting safety
• Camera shutter control

Operating modes:
• A-B straight run
• A-B with acceleration controls (ramp/Ease)
• A-B-A Bounce mode
• Time-lapse mode with built in intervalometer and camera shutter control.
• Six key sequencer for more complex moves.
• Stop motion functions for animators.
• PTZplus real-time camera functions.

News Update: 13/01/23
The Digital Bird mainboard has been updated to version2.0. If you are still building your system with kits purchased before this date be assured the new update only adds convenience not additional functionality. The changes are as follows:
1) There is no longer any need for a ‘Y’ cable between the OLED and the encoder. An additional port has been added for the OLED
2 )The resistor patch is no longer required on the back of the board.
3) There are now 2 ports for 2 limit switches on the updated slider again no need to share the single port.

Updates:
I have added an additional focus motor mount which allows the focus motor to be mounted on the right hand side of the camera where the motor is less obstructed. The mount parts are 18 & 19 glued together and must be printed as shown to avoid the tube mount simply splitting along the layer lines when tightened.
The mount fits under the camera L bracket and is held in place by the same 30mm long low-profile bolt used to secure the camera swiss clamp. Note however a longer RJ45 cable is required for this location. Part 005_100 the focus mount for the other side has also been updated.
