I already have the mechanical outline captured in a DXF file; what I need now is a matching PCB-layout template inside Altium so I can reuse it across future designs. Once the template is ready, I’ll hand over two existing Altium projects. Your job is to drop each board onto the new template and enlarge the four mounting holes (current drill size will be in the files; target size we can confirm together before routing). Key points you will handle • Import DXF, create the board shape, keep all layer names, stack-up and grid settings tidy so the file shows up as a clean “PCB layout template” in Altium. • For the two boards, migrate them to the new template and update the mounting holes only—no component relocation or net changes expected. • Retur...

You will also travel to customer sites to install new food-processing machinery. Once the hardware is in place you may have to work with PLCs, tweak ladder logic, and verify that every sensor and actuator reports correctly before sign-off. Although troubleshooting is part of life in the field, I measure success by how well the preventive work you do avoids unplanned dow...

I have a device that runs on 12-48v DC, drawing up to 5A at 12v at bootup. This then settles down to 2-3A for normal operation. I need to run this device from my 12v vehicle battery – either via a cigarette lighter plug or direct battery connection. The device runs fine at 12v, but runs better at a higher voltage. The device’s supplied 240v power supply outputs 30v @ 2.0A/60W. The problem is that when the vehicle engine is started, the current drops and the device reboots. I need a circuit and PCB design that will: a) Be robust enough to live in a vehicle b) Switched (off board) – via screw terminals c) Fused (either on PCB or automotive blade fuse connected to PCB via screw terminals) d) Reverse polarity protection e) Reverse connection protection (i.e. po...

I have a new Segway-style scooter in development and need a seasoned embedded programmer to create the entire self-balancing (gyro/IMU) firmware that will ship on the production boards. The scooter is meant for personal transportation, so reliability, safety and a polished riding feel are non-negotiable. Above all, the control loop must react instantly to rider input—acceleration, braking, tilt corrections—without hunting or lag. I will provide hardware access for bench testing as well as real-world ride data; you will transform that into a finely tuned PID (or equivalent) solution that keeps the deck level and feels natural underfoot. Beyond the core balancing logic, I want a highly customizable interface layer: riders should be able to tweak parameters (speed limits, sensit...

I want to take traditional conveyor-belt tensioning a decisive step forward by creating a completely motorized, cable-and-pulley system that adjusts itself on the fly.
