So I cut all the wires, neatly bundle up the ends in case future reversal is needed and go get a Coke.
ADDING A JOYSTICK TO CONTROL THE BESCOR MP 101 DRIVER
We will not be using any of those, because, power for the motors is to come courtesy of the Moteino and an external power source, motors will be directly interfaced with the motor driver and operational drive limiting shall be done from within the code logic. Several thin wire bundles connect the electronics to the rest of the platform, including power wires, direct motor wires as well as operation of the limit switches. All of the electronics rest on a small PCB bolted to the plastic backplate along with the DIN connector and the operation mode switches. Once the screws are out, the backplate needs to be slid down from the top as it is embedded into a channeled groove. A long thin Philips-head screwdriver is all that it is needed to remove the six screws holding the backplate together.
Luckily, getting at the electronics of the Bescor is not a difficult task, as most of it is mounted on the back plate.
Unfortunately, we have done as much as we can using the stock port – the imposed limitations on the original scope of the work for the Bescor will not allow for further explorations into extending the operational capacity of the platform. This is a simple approach as it allows for the Bescor to remain in stock form, as well as retaining the ability to use the original remote. Why do so? Up until this point, all of the electrical paths towards the Bescor were done through the stock DIN port, used for the original remote. Operating on the Bescorīeing happy with the mechanical base of the Bescor, we are setting out to remove offending electronics and interface the DC motors directly. Controlling the motors directly from the Moteino makes sense for at least three reasons simplification, increased power and torque, and extended movement control. In addition from the limit switches and the integrated motor drivers, it is bound by the requirement to work with both batteries and wallwarts, use a wired remote and implement basic automated panning.Īnd since we are already using a microcontroller with some power and programming capabilities, it is only natural to move all functionality to the internal logic and eliminate the superfluos electronics in the Bescor. But as production costs dictate, the resulting product mates quite a mechanically sound platform with less than stellar control electronics. It makes for an interesting read – for what it sets out to be, it is a wonderful product in its original form. Within that same post, there are links to the patent applications for the inner workings of the Bescor.
This post is bound to be longer, so bear with me.Ī few writings back, I elaborated on our choice for the Bescor MP-101 as the basis for the project. …but let’s not get ahead of ourselves here. Speeding up and slowing down is great and all, but can the platform move the camera along with itself? As it stands, it needs to be able to safely move around a loaded DSLR camera with a typical lens, an external monitor, zoom and focus motors, a cage to mount all these to, control boxes with the electronics to run the whole thing… Will I choose water over wine and hold my own and drive? …so if I decide to waiver my chance to be one of the hive,
