Hey there I'm professional electrical engineer having specialisation in Electrical control systems I'm expert in circuit design and simulations tasks I have vast experience in PCB DESIGNING I will provide you with all Gerber, BOM, Schematic and 3D files I'll be waiting to hear back from you

If you know the min/max current that this heating fan draws, then this implementation is very simple. I can give you an idea which will be very simplistic way to achieve it. I can not share the technique here so can discuss over messaging system. Will design a small PCB for it as well. Thanks. Please get in touch.

POSSIBLE to do this depends on the wiring topology. If you are trying to build this to make a load control through wireless module, it can be done. But your drawing is ambiguous. Please feel free to connect to discuss the effort and wayout. Thanks,Raj.

Your project is really interesting. I will do your schematics in Eplan and you would get all componet list with the schematics. Before I start I would need additional info. Feel free to contact me if you are interested.

Hello, I am pleasure with your job as detailed. Thank you for the job posting. It’s a pleasure to meet you. I’d really like to work with you on this one if possible!

Hello, I am an electronic engineer and electromechanical technical. I have more than 6 years of experience in electronic design of hardware and software. 1- For that configuration you could put a resistance, and you could get what you are looking for, the only drawback is that it will be big and warm, and can be expensive too. 2- can put a extern transformer 3- could also analyze to put a source without transformer If you want to know something else, do not hesitate to contact me I think it could be of great help for your project. I am already at your disposal. Best regards Guillermo
