Cosmos ADC is powered from USB, so cutting the red wire is not a solution - it will not work :) And, as the black wire is still connected, the ground loop is not eliminated.

I just cut the red wire in my usb cable :)

Here the latest version of the code running on LEDs. At minute 19:58 the diffusor is removed. And this is a simulation of a 128x128 matrix:

I must admit I've never used any maths functions on my scopes. I scope both an and b of my differential channel with reference to 0v (single ended) and I scope between an and b to get the differential signal with the common mode noise gone...

Hello RNoble. Sorry to read about you blowing up components. These ws281x leds work well with rs485 transeivers. It's a common way to interface with these leds and you will have no more flicker issues. I use the standard max485 cheap ones but...

Unfortunately its very difficult to get to the encoders. I could swap encoder and cable at the controller end to prove it is the cable and encoder, but that has risks i need to feel comfortable with. This hoist runs a master slave setup. Were...

Hi MarkT Not easily, that would/has only be done when the machine won't run due to an encoder issue. Even moving cables (and the encoder attached to the end) between inputs needs carefull consideration before doing. The problem is these...

Hello All. I'm after some feedback on noise I'm seeing on some encoder wiring. I put together a video to communicate the issue to a previous electrician who worked on the equipment. I thought there might be someone in this community that enjoys...

Hello morind79. I looked up the TaskScheduler library and the readme suggest it allows something with results equivilant to concurrent processing. I'm guessing your tasks can use some idle time, like when the motors are running, and instead of a...

It's taken a month but I have my ftm class to make using a teensy 3.2 ftm module in input mode easier for my purposes. In case it can help anyone else: https://github.com/gibbedy/teensy-3.2-ftm-input-mode
