I just wanted to clarify that the output needed to be sinusoidal. Please let me know what all would be provided with the solution. Please, find the attached file with the design requirements. Please, let me know if you need clarification on anything. If you would like to quote it in stages that would be fine. I would like it in 20 days or less, I would like you to supplying the complete tested working control and buy components, because I don’t have hardware. This project will be difficult for you if you have not developed a frequency drive before. Do you have an idea of what you would need? Have you developed a Frequency Drive or something similar before? I would like it in 20 days or sooner. I want you to supply all the material it will be great. I will send the fund into milestones based on progress. You will have to design and hardware for the VFD controlled by raspberry pi and Touch screen. The main part of the design is VFD design ok. I do not have the hardware. I am an Electrical Engineer and able to program in C/C++. I do not have the resources to develop this product so; I will need the complete solution. The main part is the VFD design and interface to a raspberry pi that will utilize a touch screen to make the output adjustments. I mentioned all the details over here for more info please, find the attached pdf file thanks.

I am starting a task that involves attached and remote sensors being monitored by a Nordic nRF51 (and hopefully nRF52) core. I need to find someone to help with Firmware. I have the nRF51 and 52 dev kits and can run the demo files Nordic provides. As I identify needed blocks of firmware I would like to provide you a description and get a cost estimate then proceed from there. The first block that I need is to be able to connect to an android device and have the nRF51 report temperature on an android app. What would be your estimate to set that up and send me the files so I can test it?

Hi. I need to develop and setup a system that will collect the environment data using a luminosity, temperature, pH, and humidity sensor, and save it online into an application or database, and if no connection locally. This is to be used to monitor the plant environment for an aeroponic system. You will be focused on the hardware/software side of the sensors and sending the data, and I will be dealing with the front-end application. I've seen something like this, but looking for easier and better ideas. http://rominirani.com/2014/12/04/temperature-logger-powered-by-arduino-orchestrate-io/ Want to use one of these (please let me know which one you would use and why): 1. https://www.arduino.cc/ 2. http://www.udoo.org/ 3. https://www.particle.io/ 4. https://www.crowdsupply.com/pinoccio/mesh-sensor-network 5. http://store-usa.arduino.cc/products/e000052 It's a pretty simple job, but I don't have much experience with hardware and could use the assistance. I have not purchased the sensor either, but I would also need them to be compatible with on of the devices listed above.

Hi - we urgently need a good engineer to give an mcu more accuracy to complete the job --it is in khz from 0.01 to 999.99khz but the current mcu is not accurate--can you improve the accuracy to 99% and finish assignment--then we also need assembly and program in C

Needs to be in Massachusetts We are looking for a knowledgeable electrical engineer to redesign or optimize an existing control system for manufacturing. Looking for experience in the following areas: Microcontrollers, Sensors, BLDC Motors, Microcontroller programming, PCB design, Circuit design and Designing for manufacturing. The goal is to design a control system to drive 3 brushless dc motors using PWM signals from the microcontroller(s). In addition, data from an accelerometer needs to be read and displayed on an LCD screen. All parts will be paid for. You will be expected to suggest the proper hardware based on given specs, design the circuit and demonstrate that it works as expected.

Hello, I need a customized bootloader as source code for the stm32f4 and F0 series. The bootloader will be used in a system, which is interconnected with halfduplex RS-485. Multiple Controller in the system will have their own ID and there is a master mcu. Its not relevant how to get the bootloader into the system, its allowed to use SWD or JTAG. I would also need a puristic gui where I can upload the firmware into the controller. For the start I only need to evaluate the bootloader with a discovery board, later on it would be great to select each controller in the system for update via a spinbox. Also a small tool, where the firmware is encrypted, would be cool including the ability to write the key into it. It would be a plus, if the bootloader can have encryption. Best Regards, Antony
