About us

BaseCam Electronics was founded for the purpose of developing camera stabilizing solutions based on direct drive brushless motors.

The company's first products are the BaseCam SimpleBGC controller — previously marketed under the name AlexMos SimpleBGC (BGC stands for Brushless Gimbal Controller) and Extension board for building 3-axis stabilizer systems. The controllers are used to build camera stabilizing systems for both handheld and UAV mounted cameras.

Basing Gimbals on our solutions allows a wide range of cameras to be stabilized, from GoPro to Red Epic.

News

SimpleBGC32 - a new version of Android App was issued.

In this version:
— Support of the firmware 2.5
— Some new settings
— Support of Bluetooth 4.0 (BLE)

SimpleBGC App is a final version which supports 8bit boards and won't be evolved anymore.

You can get the App here.


The issue with automatic firmware update

To solve the issue you just need to download GUI of needed version from our site again.

The issue is caused by new SSL certificate which we started to use.


New firmware 2.50b2 for 32bit controllers has been released

Changes in this version:

  • User-written scripts (see Language Reference and user manual)
  • IMU temperature calibration and compensation.
  • New tool "Analyze" to make analysis of system response.
  • Notch filters have adjustable gain (0..100%)
  • "Motor outputs" settings group is changed to per-profile basis
  • GUI and firmware support Bluetooth Low-Energy (BLE) module communication (experimental)
  • New setting group "Outer PI controller" to adjust values for outer (cascade) PI controller (default value is 100 suit most setups)
  • New option "Swap frame and main sensors" to use frame IMU as main IMU and vice versa
  • New option "Gyro Deadband" to cut off gyro noise around zero (that may be audible as 'white noise' in heavy setups)
  • New option "I2C high-speed". Use it carefuly: high speed mode may cause I2C errors.

Details and required files can be found here.


SBGC32_I2C_Drv expansion module has been developed

This module is intended to work as a part of the SimpleBGC camera stabilizer system, performing a motor driver function.

Unlike regular scheme, where all motors and encoders are connected to the main board and driven by the single MCU, in the modular scheme each motor is driven by its own MCU, that lets to optimize cabling: encoder is integrated into the PCB for each module, and motor's cable goes to it by the shortest way. Only 5-wire cable joins modules with the main controller.

This expansion module is supported only in the encoder-enabled version of SimpleBGC firmware.

Details and required files can be found here.

Letus Helix Jr. was awarded by News Shooter at NAB Show as Best Pro Video Camera Accessory

Needless to say that Letus Helix gimbals work on BaseCam SimpleBGC 32bit controllers. From very beginning, Hien Le, owner of Letus Corporation, with his crew devised the unusual design for the gimbal. It took some time from our team to adapt our solution to the demands of Hien. It was not for nothing.

Letus Helix Jr. gimbal got the winner at NAB Show as Best Pro Video Camera Accessory.


DIY motion controller for gimbal

This DIY tutorial helps you build a Bluetooth motion controller for any SimpleBGC-based gimbals! This means you can simply move the controller, and the gimbal will match its orientation. This is the second project from Mark. We thank him for the work done.

BaseCam filter tuning

This is a short tutorial showing how to use BaseCam filters to provide better gimbal performance.


Problem with the spektrum port

Some versions of the controllers can have a problem with the spektrum port: the satellite receiver does not get enough power from the 3.3V internal voltage regulator, resulting in unstable operation (symptoms: signal interrupts, LED blinks randomly, on binding attempt system goes to reset).

Find out how to solve the issue.

How to recover firmware on your 32-bit board

Suppose that you somehow damaged the firmware on your board and need to recover it. The following steps will help you to do that.

  1. You need GUI version 2.41b5 or higher. Find it on the download page.
  2. You also need a recovery firmware. You can find one here.
  3. Close FLASH pins on the board using a jumper shunt.
  4. Connect the board to your PC via USB. Note that the Red light has to light up on the board.
  5. Start GUI and do the following steps:
    • Select appropriate COM port. Do not press button "Connect".
    • Open TAB "Upgrade" -> "Manual".
    • Specify location of Firmware HEX file.
    • Select Board version -> v3 32bit.
    • Press button "Flash".
    • Wait until uploading to be finished.
  6. Unplug USB and remove jumper.
  7. Do automatic upgrade as described in the User Manual.

Rebotnix Gimbal Control for iOS

The rebotnix Gimbal Control allows you to remotely control a BaseCam SimpleBGC controller with an iPhone or iPad in conjunction with the rebotnix Apple and Bluetooth certified Bluetooth hardware module.

Rebotnix Gimbal Control is available in App Store.
