This type of led indicator is indeed intended for the direct replacemen of incandecent type indicators and as such does not require a dropping...
Sorry Jim, 20mA for the CT's and 2mA for the INA219. I changed the post. Good catch!
I have been testing various current measuring devices for my layout. I started out using Current Transformers (5A:5mA) through a voltage divider...
Just requested access, also willing to help where I can. Dan
Tom The DCC++ Base Station inherently DOES NOT provide auto reverse functionality. A separate device is required. Dan
You are correct. On the IBT-2 tie pins 3 & 4 together and then connect to pin 3 of the Arduino (Uno or Mega) for the Main Track. This should...
Travis; I think you will find that the IBT-2 current sense lines are wildly inconsistent between units. Even the two BTSD7960 chips on the same...
It does work and all but the original come from china one way or another (maybe it too). The arduino web site does show it available at $22.00. I...
Try here Travis,...
FlightRisk; An excellent set of videos by the original creator of DCC++, Gregg Berman. In four videos he walks through the entire concept to...
Vasilis; I believe the Head End and Power District Module descriptions above answers your first question. I'm working on the Turnout Module...
POWER DISTRICT: The Power District Module provides self-contained control of four blocks by a local Arduino NANO. Multiple NANO based Power...
HEAD END: JMRI is used to control the entire system on a Raspberry Pi4. Keyboard, mouse, two HDMI monitors, a powered USB-3 hub and an Arduino...
vasilis, I'll answer you last question first, I thought I had answered it yesterday but the post was still waiting for me to push the Post Reply...
Vasilis, Your circuit does indeed perform both the inverter control for the base IBT's and the autoreverser for the dedicated IBT. My original...
I have started a Modular DCC Control System that is part DCC++, CMRI and JMRI. This is kind of a “kit-bash” project where I have taken various...
Erik, In the circuit you posted the DCC signal is sent through the opto-isolater and emerges on pin 6 where it goes down to the IBT-2. One portion...
Vasilis; Regarding the 74LS04, the signal I receive from the DCC++ Arduino MEGA is the raw 5vdc pulse, not bipolar, so the 74LS04 inverts one side...
Erik, Here is a quick copy of the schematic. I can post the eagle files if desired. This is part of a modular DCC++ / CMRI system i am building...
Here is the most recent version of my prototype Multi-District controller. This prototype is only two blocks, the final version will be four...
