I need a design of a device that is able to generate random frequency in a setted range (for example 50Hz - 200KHz). This device should be connected to a piezo or a vibromotor. An amplifier needs to increase or decrease the intensity of the vibration. With an User Interface is possible to setup the parameters (frequency + intensity). Please note: I need only schematic and PCB design.

I am a teacher assistant at electronics and communication department. I did many projects in analog and digital circuit design and implemented PCB layout(see my portofolio). These are some examples of my projects: - nodemcu for controlling remotely through wifi, - ESP interfacing with arduino, also using bluetooth module for remote control - dealing with different types of motor encoders, - using mobile application for remote control. - U2F PCB layout. - Smart home using (PIR, temp. sensor, IR sensor, motors, door lock, alarm, bluetooth). - Robotic arm using (servos and arduino). - Helperbot for simultaneous localization and mapping using (raspberry pi, kinect, ultrasonic, motors). - Amplifiers using (BJT and OPAMP). ... etc. It will be great to work together.

Hello I have got your job posting “Design of random frequency modulation device” and I am very much interested to work in your project. I am a circuit designer and have more than 5 years experience of working with the Analog/Digital Electronics,PCB designing, Embedded systems(Arduino,Rasberry pi ,ARM processors ,PIC microcontrollers,Wireless boards,TFT Touch Displays,All types of sensors and actuators). i have done tons of similar projects So, I think you’ll find that, I have the skills you’re looking for. For more on my skills and successfully finished projects, please have a look on my Profile and Portfolio. I have a PCB manufacturing facility and all the components available here with me so i will develop a working prototype according to your specifications and then send you the layout and schematics so things will work for sure.I will remotely guide you and help you build the system on your side. I am always available on Email and Skype. Please have a voice or video chat if necessary. I shall be available round the clock and able to start your project as soon as possible according to you. Thank you for your consideration, Best Regards, Haseeb Shafqat

Dear, Client. I would like to say this is my fortune to show you my hardware skills. I can bring your idea to live and you can reach the goal absolutely with me. I have 10+ years experience in hardware design (schematic design, PCB design...). My develop tool is Altium Designer, CADENCE. I have designed many high speed devices in embedded system. My recent design is AM5728 Core Board. (quad-core, 1.5GHz, DDR3 4G, EMMC 32G, Gigaethernet, usb3.0,...). And another is PCIe v2.0 to 4x Ethernet (or 4x usb3.1) convertor. All design is passed in several EMC tests. I have designed MEMS tracking board, ultrasonic distance measurement and so on. My design is very stable in industrial environments. I think your design is not difficult. but the most important thing is EMI, EMC. I have been working main hardware developer in large scale industry product company. Designing the PRODUCT is very different from designing the general PCB (test board, kit,...) You can feel everything that is my real skills in hardware development. Look forward to working with you for a long time. Thanks! Hope to see you soon

Hello. I am senior Microcontroller developer and Electronic Engineer. I have plenty of experience in the PWM Controller device development. I can design the circuit and PCB for the controller used the MCU such as PIC ,ATMEGA,STM32. I have designed the various device using the Altium Designer. Also I can write the firmware as well as design. Due to my experience in this field development, I will bring you the perfect result in time with high quality. I hope we can discuss more details via a private chatting. After you see my profile, you will think I have no experience. I have been developed the complete project, and I have the actual experience. I hope you think again about me I look forward to your response Best regards.

Salve, ho letto la descrizione del suo progetto e sono molto interessata a lavorare per lei. Mi chiamo Victoria e sono una studentessa di ingegneria elettronica, con esperienza in Progettazione di Sistemi Elettrici ed Elettronici e in PCB design, in quanto vincitrice del secondo posto nella competizione internazionale della robotica Robocup Junior, alla quale ho partecipato con un robot progettato interamente da me. Ho già preso parte a svariati progetti che richiedevano la progettazione di circuiti stampati e sarei molto interessata a discutere dei dettagli del suo generatore di frequenza.

I am a retired electronic circuit designer. One of my projects was a generator for ultrasonic bonding for the tiny wires in integrated circuits. The generator was used in the span of 40 to 250 kHz. This generator was capable of much more than your requirements. It could find the resonance frequencies of interest, it could control voltage or current or power delivered to the load. I can complete your project including PC based user interface with the USB communication to the board. Just need clarifications: 1. The generator should operate in two modes. First, totally random choice of operating frequency and a second to operate by frequency given by the operator or just latter. 2. Maximum levels of output voltage and power. 3. Board desired dimensions. I am working and can deliver documentation in Altium and Gerbers for board fabrication.
