How to control multiple relays? #3

Closed KrishnaPG closed 6 years ago

KrishnaPG commented 7 years ago

Thanks for sharing this good work. It is helpful.

Wondering if you have this design extended for controlling more than one relay. And also, how to make it work with dimmers etc (in the same board alongside with normal relays)?

ArnieX commented 7 years ago

Hi, this is what header is for. You can connect extra accessories to the board. If you would like it to control big relay board that should be possible if this board would be equipped with I2C. Dimmers would work too but for that I recommend dimmer that is referenced in “What’s next” in readme.

KrishnaPG commented 7 years ago

Thanks for quick reply @ArnieX Will look into the header functionality. Thanks again for sharing this good work.

ArnieX commented 7 years ago

You are welcome, hope you will like it if you happen to build few.

In the folder which file is the board file? I am trying to experiment with the board to make small changes, such as using nodemcu (in place of esp), and other options such as using mounting headers instead of having to solder etc. Could not find the source files in the repo

ArnieX commented 7 years ago

Sorry, no source file available. Using NodeMCU is overkill. Anyway NodeMCU is good for prototyping, this is actually finished thing. If you want to use NodeMCU the best would be to use other ready made modules, like relay module, etc.

Thanks. When sending this design for PCB manufacturer (local) for a quote, they are asking for BOM. Wondering if there is BOM csv file that you can share?

ArnieX commented 6 years ago

Well, I'm not sure. PCB manufacturers usually need gerber files. I don't know what is BOM, but I can ask my colleague who did the actual PCB design, if he knows what this is.

KrishnaPG commented 6 years ago

BOM is short for "Bill of Materials". They would need it to assemble components on the PCB (after the creation), and also to give the estimate/quote. Essentially it tells which component goes to which location (on the PCB) and how many needed and what is the exact component brand/value etc.

ArnieX commented 6 years ago

Hi, this information is in readme. You can therefor assemble BOM file yourself ;)

KrishnaPG commented 6 years ago

Thanks. Wish I were that expert :) The system (that generated the gerber etc.), must have auto-generated all these BOM automatically. It follows certain format. Besides, I want to make sure that their placement mappings (which is not provided in the readme) is correctly captured. Request you to kindly check with your mentioned Friend - he must already be having this BOM file. It would be great help.

KrishnaPG commented 6 years ago

Also, the placement mapping of these components is important. For example, there are multiple resistors listed in the parts. The generated BOM file keeps the mapping correct.

ArnieX commented 6 years ago

Just one question. Are you going to make it in big amounts? If not we recommend you to solder manually.

KrishnaPG commented 6 years ago

Not big amounts. I am more of software guy, so I am asking my friends to help me build samples. In that process, they asked me to get the BOM. It helps them to recreate the board correctly. Hence the request.

ArnieX commented 6 years ago

Then again, exact mapping table is included in readme. This should be more than sufficient to do exactly what you need. I use it too when soldering.
