I’m bringing up new hardware built around an MPC-series PowerPC processor and I need a seasoned low-level developer to create the initial firmware that will boot, initialize all on-board peripherals and hand control to the operating environment. The work is bare-metal: you’ll be starting from the reset vector, setting up clocks, memory controllers, caches and MMU, then implementing board-specific drivers and a minimal diagnostic shell so I can verify the platform in the lab. Your background should include solid C and PowerPC assembly, familiarity with typical toolchains such as GCC or CodeWarrior, and a track record of writing or modifying bootloaders (U-Boot or custom). I will supply schematics, memory maps and any other technical details you need as soon as we start; what I ...

I have developed a Velostat-based pressure mapping matrix. The setup uses 9 copper columns on the top layer and 9 copper rows on the bottom layer of the Velostat sheet. The column lines are connected to a CD74HC4067 multiplexer (C0–C8) with 10 kΩ pull-down resistors. The controller used is an Arduino Mega. MUX signal → A0 MUX select lines (S0–S3) → digital pins 2, 3, 4, 5 Enable → GND VCC → 5 V Copper rows → digital pins 22–30 This setup worked perfectly. I was able to read the data and plot a proper pressure map using Python. However, the problem started when I rebuilt the exact same circuit with a different Velostat sheet. This time, the Arduino serial monitor shows only zeros, with no pressure response. When I removed the pull-down resist...

I need a complete Simulink-based representation of a low-voltage DC microgrid that demonstrates stable power-sharing through droop control. The model must combine two renewable sources—a solar panel array and a wind turbine—each tied to the DC bus through appropriate DC-DC converters. A battery pack, modelled with its bidirectional converter, will serve as the main energy-storage element. Please include a representative mix of static and time-varying loads plus a simple load-management block so I can toggle demand profiles during simulation. Key points I expect you to cover • Implement conventional voltage–current droop control (or another proven droop variant) so the sources share power proportionally under changing irradiance, wind speed, and load events. &bul...

I want to turn a single-board microphone into a self-contained, cloud-ready product. The board must capture audio, encode it in MP3, and push the stream in real time to a designated AWS S3 bucket over 802.11ac WiFi. Power will come exclusively through USB-C; both ends of the board need USB-C connectors so the unit can sit inline between other USB-C devices if required. My preference is for a small, production-ready PCB that combines a suitable codec, a WiFi SoC (ESP32-S3, STM32 + Murata, or anything you recommend that supports 802.11ac), and the necessary power management so it boots as soon as 5 V is present on the port. Firmware should expose a simple JSON or REST configuration endpoint (SSID, password, S3 bucket, access keys) and handle reconnection gracefully. Deliverables • S...

Project goal, to create a Bluetooth transmitter that pairs with the insta360 x5 camera and transmits line-in audio via Bluetooth to the camera. I need an experienced Bluetooth-Classic analyst who can hook up an Ellisys BR/EDR sniffer to my setup and hand me clean captures of everything that happens between an Insta360 X5 camera and its Mic Air wireless microphone. Here is where I am right now • I have proved that the camera pairs over BT-Classic, not BLE. • Using an ESP32-A1S I can reproduce the pairing, yet 3 seconds after I start recording, I get an audio anomaly and the entire recording stops. There is no audio saved in that time. What I must understand • Full packet-level flow for both the initial pairing and the ongoing A2DP + HFP/HSP streaming sessions. ...

I need to reproduce the complete control model from a published paper on grid-connected photovoltaic inverters—specifically the PI + Resonant current controller—and then push the work further by adding an intelligent ANN-based control structure. Everything must be built and run in MATLAB/Simulink so that I can validate the original results first, then make a clear side-by-side comparison between the classical and the new approach. The task starts with an exact replication of the paper: identical parameters, same test grid, and matching waveform plots. Once that baseline is confirmed, you will design, train, and integrate an artificial neural network controller, tune it, and show how it behaves under identical scenarios. I am especially interested in response time, harmonic dis...
