As we move a servo it would be more than nice to have a position feedback! The servo itself have a potentiometer telling the absolute position, but a standard Servo only have a 3 pin interface Power and Position setting – it gives no feedback. This is a common issue with many available actuators –…
Creating a module that can control a PowerServo is fine, but what about using it from BSA? What do we need to do? From a user perspective very little. In this example I just created a PLD State Diagram block with 3 input methods and one output method. It is this simple once the underlaying…
I am quite found of using 60 to 150Kg Servo units, but driving those units is an issue as I need a RF Signal and a 12V PSU capable of 5A. The example board below contains a separate DC/DC so I can deliver 8V and 12V with a single cable for those larger servo’es –…
This is the 24V power modul. It uses a 3rd party isolated DC/DC to support 24V “as is” and 5V isolated. It has protective diodes and capacitance for the 24V side. I could have needed more connectors for power distribution, but these boards are very small. As this is a PLC design we use. This…
Picture below is an Ethernet modul. It connect to the PLC on the left side and have a waterproof Ethernet connector on the right side. Again I have replaced the SWD connector at left bottom with TC2030. I don’t expect to be using so many of these since CAN/CAN-FD is the primary link technology, but…
I have done several experimental modular control systems that was scalable, small in size and based on MCU’s. My first experiment was with Basic PI Hats and I later did a smaller, modular system illustrated below. The system below was actually a great success. Specially the keyed connectors worked well. What did not work so…
I created the footprint for GX16-8 and updated the 3D with a few details. I will see if I can add the thread as well. I quite like these connectors, but I am a bit concerned that I only find them on one source on Aliexpress + I realized that these connectors have a different…
I will upload these packages on github (here) because it is 2 days wasted work having to draw them and I depend on others publishing their 3D packages myself. Just be aware that these are Beta – their accuracy is subject for testing. I will draw the last five as I get them. Have fun.…
I fancied using GX16 connectors in a project since they are low cost, robust and can be made water proof. I found 2,3,4,5,6,7,8,9,10 and 12 pin versions with bend pins so they can be mounted directly on a PCB and fixed to a panel. But, what I did not find was 3D models for KiCAD,…
I have lately had the priviledge of working with two vendors of mobile, electrical vehichles – one used a self-developed system designed for volume production series, the other was a larger industrial vehiche on prototy level where they started with a standard PLC and a small cabinet. Usage of a standard PLC “kind of works”,…
