I need a well-structured Excel workbook that walks me through selecting every major component for a standard EOT crane. After I type in fundamentals—capacity, span, duty class, lift height, ambient factors—the sheet should calculate and recommend suitable options for three areas: the hoist system, the bridge & runway, and all key electrical components. Formulas must be laid out transparently in a way that lets me trace or adjust them later, with a separate tab summarising assumptions, safety factors and any reference tables you draw from IS, FEM or comparable crane design standards. Because I’m open to any brand that meets the spec, keep the logic brand-neutral yet show the exact parameters I’ll need to compare catalogues (motor kW, gearbox ratios, rail sizes,...

1) Project goal Design a single PCB device for testing cable harnesses up to 25 wires, where both ends of the same harness are connected to the board: Side A: 25 lines (A1..A25) Side B: 25 lines (B1..B25) Total: 50 signal lines on the PCB. The detailed test logic (continuity/shorts/mapping) will be implemented in firmware later. For this phase, the key deliverable is robust hardware (schematic + PCB) prepared for such testing. 2) Scope of work (hardware only) Electrical schematic PCB layout Production files: Gerbers + drill BOM (with specs and acceptable alternatives) Assembly files (pick&place/positions) preferred Short mapping table: MCP23017 pins → A/B line numbers (Firmware is NOT required in this phase. Optional “I2C scan / basic blink” is a bonus.) 3...
My heating installation is already wired with motorised valves and PT-100 temperature sensors; what it still needs is a clean, reliable control program running on a Schneider Electric PLC.

I need a clean, well-commented Arduino sketch for the Pololu 3pi that lets the robot visit six preset locations, interact with the magnet at each spot, and return to its starting line in under four minutes. The only sensing method available is a magnetic sensor array, so all point detection and interaction logic must rely on that hardware. Two run modes have to coexist in the same program and be switchable through a simple flag, jumper, or serial command: • Intermediate – the robot must physically touch the magnet before leaving the point. • Difficult – the robot should recognise the magnetic field, stop just short of contact, and then continue. Between locations, I expect a mix of straight dashes and graceful curves; please handle path planning so the 3pi&r...
