    I am looking for a freelancer to design a simple 12v circuit for me with the purpose of powering LED lights, charging a battery, or controlling a motor. The circuit will utilize a salt water anode timer, a piezo speaker deactivation, and a FOB. I do not have any specific components or specifications in mind for the circuit, so I need the freelancer to suggest these components and specifications. My preferred method of delivery for the circuit diagram is in PDF format.

    I took a long time to connect the equivalent circuit of the piezo material (Quartz) to its electrodes (attached on both sides of the quartz), gave it sine voltage, and did a harmonic analysis to see the amplitude of piezo oscillation in the specific range of frequency. I added the CAD data directly to the workbench and added the APDL commands (attached) to the modal analysis (added before the harmonic analysis). Based on the errors I receive " Element 18590 does not have all of its required nodes defined. The E command is aborted" I am guessing that the problem is with nodes and elements that I introduced. It would be really appreciated if you can help me with this issue.

    I'm looking for someone who is capable of converting a .WAV file to the approriate Arduino code to let it ring with a Piezo ringtone. These ringtones will be used for an electronic device with piezo speaker, in which we are capable of producing audio between the 3.5Khz and 4.5 Khz frequencies. This of course means that the ringtone via the piezo speaker will not sound the same as the original .WAV file, however the type of tune needs to remain the same. The project has a quick turn-around time, so it's important to find a reliable Freelancer able to work on a short timeline. Experience in sound engineering or audio production is a must. I've tried it myself using these steps: 1. Create the Wav file. 2. Analyze of WAV file. Using WAVE and NUMPY. 3. T...

The Nano should be able to recognise whether the 6 switches have been set in a Normally Open or Normally closed state. This will change after every use. 4. If a NC or NO switch subsequently changes state the board should alarm for 15 seconds and then assess the condition of the switches again before returning to monitoring them. 5. Each Analogue Switch should have an LED associated with it. If the switch changes state (Example NO to NC) then the LED should illuminate at the same time as the buzzer sounding at requirement number 4. Notes: The buzzer will be a regular piezo buzzer.

    This project is two fold as you look at the schematic- piezo and metal tank. The suggest is made of placing a second inductor across the primary of the transformer to improve the driver's efficiency . The value of the inductor is empirically picked to minimize power consumption (it offsets some of the capacitance of the piezo transducer. The optimization need to function with any piezo at the 63kHz range Also we consider a push/pull transformer arrangement driven by a similar microprocessor arranged input. This is typical of higher power ultrasonic drivers.

Here is an example setup scenario of setting up alarm time: Alarm Se...

    I have an Arduino nano and a piezo speaker. I need code saved as an ".INO" file so that I can run it for making the piezo buzz at 40,000Hz (ultrasound). I want a code-only solution because I don't want to have to add resistors transistors, etc. All I want is for the thing to run with just 5 volts DC with a piezo buzzer soldered onto the board.

    Hello, The title of the project is Numerical Characterization of Ultrasonic Atomizer. In this project, we would like to simulate a fluid flowing through an atomizer. This atomizer is a resonating part, meaning it will vibrate at a resonant frequency. This vibration is provided/imparted by a piezo-electric transducer which is attached to the atomizer. This vibration creates standing waves inside the atomizer. When fluid is made to flow through this atomizer, due to the presence of standing waves, fluid gets atomized into droplets. We are interested in simulating this process. We have already finalized the geometry of the atomizer. But we are not able to simulate the vibration which causes the atomization. In the attached paper "Miniaturized Multiple Fourier Horn", we hav...
