.Hello, I am looking for a forensic audio examiner to review a recording that may be used in litigation. The issue is whether the recording is continuous or whether there are signs of stopping, pausing, restarting, splicing, editing, exporting, or other manipulation. I also need the metadata reviewed, including recorded date, encoded date, tagged date, and any signs that the file may not be the original recording. Can you please let me know: Whether you perform forensic audio authentication; Whether you can provide a written report suitable for court/litigation; What file format or original source material you would need; Your estimated cost and turnaround time

I only accept the price in the bud so don't come asking my budget in inbox or increasing again I'll cancel you immediately. I need a fully-commented Arduino Nano v3 sketch that handles auto-scanning on the mm238rw 5.8 GHz 8-channel video receiver module (datasheet linked above). At power-up the Nano should cycle through all eight channels until a valid video signal is found, then lock on that channel and stop scanning. A compact LED screen mounted on the front panel must show a clear “searching” indication while sweeping and switch to “signal found” (with current channel number) once video is detected. Pressing a panel button should immediately restart the scan so I can keep looking for new FPV drone feeds. Because the Nano’s only task is to driv...

So its a Dual-Mode Reconfigurable Switched Capacitor Multilevel Inverter (DMRSC-MLI) for on-board electric vehicle (EV) charger utilization. This topology united an adaptive flying capacitor voltage clamping (AFCVC) mechanism with a reconfigurable switched capacitor (RSC) network to generate a high-resolution stepped voltage waveform using a significantly reduced number of active power switches compared to conventional multilevel inverter (MLI) topologies. Unlike traditional Switched Series Parallel Source (SSPS), topologies that rely on an H-bridge for polarity reversal, the proposed architecture employs a self-commutating polarity selection network (SCPSN), operates passively at the fundamental frequency, thereby eliminating 4 additional active switches. Furthermore, the flying capacitor...

I need a custom indicator coded for the current version of NinjaTrader that will process live market data in real time and generate clear entry and exit signals directly on the chart. No back-test-only solutions—I want the logic to read the incoming tick stream, plot its signals immediately, and refresh seamlessly as new data arrives. Core objectives • Accept only live market data as the input stream. • Display unambiguous long/short markers and, ideally, an optional audio/visual alert when a new signal prints. • Allow me to toggle standard plot properties (color, thickness, shapes) from the indicator panel without editing the source code. Deliverable A compiled .dll or ready-to-import .cs file plus the unlocked source, accompanied by brief inline documentati...

I am putting together a low-cost, 10.5 GHz phased-array radar that must spot and track any flying object out to roughly 25–30 km. The core architecture is Pulse-LFM and the whole unit has to stay hand-held and field-serviceable, so every gram and watt matters. I am looking for someone whose background is firmly rooted in radar system development; experience with phased-array hardware, RF front-ends, and real-time signal processing is essential. Off-the-shelf evaluation boards or turnkey kits will not meet our needs—we have to build the hardware from the ground up. Re-using or adapting open-source material on the software side is welcome, and I am open to AI-assisted techniques for algorithm design or UI generation, as long as the end product remains fully traceable and maintai...

I’m building a compact, battery-powered torque meter that streams live readings to a smartphone over Bluetooth Low Energy. The job covers three tightly-linked pieces: electronic hardware, embedded firmware, and a cross-platform mobile application that works on both iOS and Android. Hardware & firmware The unit will sit between the torque sensor and the user’s phone. I need a custom PCB that conditions the sensor signal (likely through a strain-gauge amplifier), handles A/D conversion, and hosts a low-power MCU with BLE 5.x. Firmware should sample torque, apply calibration constants, then broadcast the data at a steady, low-latency rate. Power efficiency and a clean-pairing workflow are essential. Mobile application On the software side, the app should discover the met...

I need a compact piece of software that will run a closed-loop control algorithm for an AC motor, using a Hall effect sensor as the sole feedback device. The firmware will sit on a microcontroller that is already wired to the motor driver stage; what’s missing is the logic that reads the Hall pulses, calculates speed and position error in real time, and then updates the drive signals so the shaft tracks a commanded RPM with tight accuracy. Here is what I expect to receive: • Well-commented source code (C or C++) that compiles with GCC/Clang, plus a makefile or project file. • A brief user guide outlining pin assignments, interrupt timing, and how to tune the gains. • A short test log (scope screenshots or serial prints are fine) proving the loop holds speed within...

I need a compact acquisition board that reads pressure sensors and sends data by Bluetooth and Celullar (SIM). Your job covers both the hardware and the embedded layer that will live on the board. System Requirements : A custom PCB (embedded system) must be designed to interface with the sensor. The system will be powered by an external battery, for which voltage and current requirements must be carefully calculated. The PCB will receive pressure data from the sensor through front-end components directly connected to the electrode outputs. A microcontroller (MCU) will scan the matrix at high frequency by sequentially energizing one electrode (e.g., rows) and measuring responses across perpendicular electrodes (e.g., columns). This scanning process allows detection of pressure points acros...

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...
