"I have a dream..." I want to build an electronic board for a smart home project. I need digital inputs (for buttons, dry-contact), digital relay outputs (230V, 16A), and some basic logic (like a way to communicate with the board via MODBUS registers for example, and get inputs when button pressed and change register value to make a light ON or OFF). If you know about logic, electronics, PCB design, etc. - I'd happy to hear your insights about making such a board. Also, I still don't have an idea of how can we design that board on your place, and have it working at last - on my place. I'd be glad to hear good ideas for that. (designing it, making it, putting on all components, and seeing it at work..) Thanks.

Please forgive if I am not using the correct terms. In the block where I live, we have a communal boiler. I have a hot water cylinder in my apartment which works by heat exchange. Sometimes the communal boiler fails or may even function at a lower than acceptable temperature. I need some sort of monitoring device which we will set to a certain temperature and this will be attached to the flow from boiler pipe (see photo) and if the temperature drops below our set temperature, then it should set the programmer to OFF this way it isolates my water tank from the main boiler. Taking it a step further, it should also turn on the immersions on the tank so that the heat in cylinder is retained and the appartment remains warm. When the temperature returns back to normal, it should automatically turn off the immersions and switch the programmer back on. The immersions are up to 4kw each and there are two of them.

I have embarked on a robotic TIG welding project, and I need help to develop a programmable power supply for the machine. I am no electrical engineer, but believe that I need a high-frequency IGBT-based inverter capable of approximating the performance of the Miller Maxstar 280 or Lincoln Electric Invertec V270-TP power supplies: - Input voltage: 415 V - Input: 20 A - Phase: 3 - Output mode: CC - Output range: 5 – 270 A - Output duty cycle: 100% at 170 A - High frequency arc start It is imperative that the power supply must be able to respond to commands from the welding machine to control the output current in the same manner as possible with either the Maxstar or Invertec units. That is, it must be capable of producing a current with a controllable ‘upstroke’, ‘pulse’, and ‘downstroke’. As I said; I do not come from an electrical background and require guidance on how to specify and design this power supply to bring my project into fruition. At this stage I am essentially...

I have attached a zip containing an Eagle Schematic and PCB Layout + an image to show my current test circuit (with labels included) for a board I've been working on. The purpose of this board/module is to allow me to manually toggle power to devices like lights, gates / anything which can be switched manually in a normal situation AND allow me to send it 5V to do the same (from a remote point). ie: Locally and remotely controllable. For monitoring the status, of the circuit, a 5v return/output line is used and monitored on the far end to indicate if the Circuit is on/off. I have created the circuit attached, with lots of help from another party, although something isn't working.. I have one circuit working flawlessly (about 50meters from source point) and therefore suspect there is an issue with interference as when I do the tests right near the remote end, I get erratic latching behaviours (same bad results on 2 different builds of the same circuit in the eagle diagram) and I...
