I need a complete 32-bit datapath and the accompanying control logic that can execute the Alpha instruction subset consisting of sll, xor, and or. This is strictly a computer-architecture exercise, so the deliverable should remain at the logic-gate or block-diagram level rather than being written in an HDL. What I expect to receive: • A clearly drawn schematic (PDF or PNG) showing every functional block—register file, ALU, shifter, control unit, multiplexers, and any intermediate buses—wired for 32-bit operation. • A micro-operation schedule or timing table that explains how each of the three instructions moves through the datapath. • The control truth tables or finite-state-machine diagram that generate the required control signals. I will test your ...

I have a completed mixed-signal Schematic circuit drawn in KiCad and I now need production-ready fabrication files. Your task is to take my schematic and generate a clean, error-free set of Gerbers with every standard layer included—copper, solder mask, silkscreen, paste, and the matching drill files. Please make sure the output complies with the common Gerber X2 format accepted by major board houses. Before handing over the package, run KiCad’s DRC—as well as a quick pass through an online viewer such as GerberLogix or J-PCBCB Viewer—so I can be confident that: • there are no unconnected nets or clearance violations • layer names match KiCad’s default naming convention • drill file offsets are zero and tools are correctly mapped Delivera...

Project Overview We are looking for an experienced PCB designer to develop a compact production ready DC-DC boost converter PCB for our RC product lineup. The PCB size is fixed and must match our existing RC chassis mounting system. The board will take input from a single 3.7V 18650 Li-ion battery and boost it to a stable constant 12V output capable of driving either BO motors or N20 motors continuously without major voltage drop under load. This is intended for mass production, so the design must be reliable, cost optimized, manufacturable, and use easily available components. The final design must be fully production ready and suitable for commercial manufacturing. PCB Size and Mechanical Constraints PCB dimensions are fixed: 60mm x 38mm All components must be placed only on the...

I’m looking to refactor and extend the existing firmware that drives my Model B Dry Bath Incubator. The current code is functional but suffers from imprecise temperature regulation, a clunky front-panel interface, and no way to capture run data. Your brief is to take the present source, retain the working foundations, and inject three clear improvements: • Sharpen temperature-control accuracy to lab-grade stability across the full operating range • Modernise the user interface so set-points, timers, and alarms are easier to read and adjust • Build in robust data-logging (on-board memory with optional USB or serial offload) I’ll supply the current firmware, circuit diagrams, and remote access to a test unit. Please work in C/C++ (or the original embedded lan...

I need detailed engineering schematics for an audio-visual system and would prefer they be created directly in the XTEN-AV platform. The project is strictly technical—this is not about marketing visuals or animated promos—so every drawing must be precise enough to guide installers and integrators without further clarification. Here is what I expect: • Clean, layered XTEN-AV files (or equivalent CAD files if you propose a better tool) that map signal flow, rack layouts, cable schedules, and device elevations. • Consistent symbol libraries and line weights so the set can plug straight into our standards. • A PDF set exported for review plus the native, editable project files at hand-off. If you are faster or more comfortable in a different pro-AV design platform ...

I need a working miniature that shows exactly how rainwater can be captured, filtered, stored and then pumped for reuse. The project is for a school presentation, but I want it built as a fully functional prototype rather than a static display, so moving parts and visible water flow matter. The model must include three core components: a small-scale filtration system that clearly demonstrates sediment removal, a storage tank that can hold the collected water, and a pump mechanism powerful enough to lift the stored water back to a higher point for recirculation. I’m open to PVC, acrylic, 3-D printed parts or any lightweight, classroom-safe materials as long as each stage of the process remains transparent enough for students to see what is happening inside. Alongside the finished mo...

My almost-finished ATMS board in Altium Designer still has its 5 V rail and ground net incompletely routed. I need a fellow Altium specialist to open the existing project, tidy up those power connections, run the usual design-rule and connectivity checks, and return the updated Altium files. No other parts of the circuit require attention, and I don’t need change logs or screenshots—just a clean, error-free design file that passes the basic rule checks. Deliverable • The original project folder updated with correctly routed 5 V and GND nets and no DRC errors related to those nets.

I need a clear, well-structured set of building and design instructions for the DEC Alpha instruction set, written for someone who is actively designing the processor itself. The focus is on how each arithmetic instruction is implemented at the micro-architectural level and how it interacts with main memory during execution. Please walk through instruction formats, pipeline stages, control signals, timing, and any associated hazards for the full range of arithmetic operations (add, sub, mul, div, shifts, etc.). Whenever an operation touches main memory—whether for operand fetches, write-backs, or cache-miss recovery—spell out the required signals and timing hand-shakes in the same depth. A concise explanation of where the cache sits in this path is fine, but the write-up shoul...

I’m adding a green LED to my vending machine controller and need clear, no-nonsense guidance to finish the job. The LED will sit on pin 15, running at the standard 3.3 V GPIO level, and must glow steadily whenever my existing “vending _enabled” Boolean is true, switching off the instant the flag is false. I already know the resistor value, so no calculations are required there. What I need from you: • A simple wiring diagram showing pin 15, the series resistor, LED orientation, and ground return. • Confirmation that the selected pin can source the required current and, if not, the minimal code tweak or wiring change needed. • A clean, drop-in Python snippet written for either or gpiozero (your choice, just keep it concise) that exposes a function lik...

I have an ESP32 Basic Core IoT Development Kit V2.7 installed in my truck and need firmware that will warn me whenever the Starlink router stays powered after I switch the ignition off. The sketch should watch a dedicated ignition-sense pin: while the line is high the unit does nothing special, but as soon as it goes low it must keep polling the Wi-Fi connection status in code. If the ESP32 is still associated with any network after a user configurable amount of time, an on-board LED must begin to flash, screen starts flashing and the internal speaker must chirp in tandem until the Wi-Fi link drops or the ignition is restored. I would like a simple LCD screen interface on the kit’s I²C display that shows real-time states (“Ignition ON / OFF”, “Wi-Fi CONNECT...
