I have 20 off Monocrystalline solar panels each of 50 volts 7.5 Amp hrs and want to establish the best circuit diagram for the system. I also have an APC UPS Galaxy 3,500 which is 3 phase in and single phase out (240v) It also has a single phase bypass output. You should be an expert industrial electrical engineer as the grid needs to approve your design. Regards John

Only a hardware development is required. No code. Time for project development: max 6 days. Sensor used for input: piezoelectric Microcontroller used to receive the amplified sound: ESP32. Output voltage range: 0-3.3V. Midpoint Bias near V=1.65V (half of 3.3V) Operational Amplifier model will be defined before start the project. We have some circuits tested but with problems as clipping and sensitivity signal. Signal amplification should be the higer possible. In oder to avoid the noise, a 10-15Hz filter can be used. We can cut any input or output signal above a specific voltage threshold Battery used: 1x3.7V (voltage used as input for sensor = 3.3V) Software to use: KiCad for schematic and any other software for simulate it (for example LTspice). Project files will be provided....

Heya there, i need a simpe design made in fusion 360, the enclosure will host a single 18650 battery, and two PCBs, with one USB C and one USB A. I need a good way to seal the enclosure, and a way to "slot" something like this battery into it. "" ive attatched a step file of what i imagine the enclosure to look like. time is of the essence so the faster you can complete the project the better, i realies it should be quick to do. enclosure will be 3d printed.

This project aims to control a Gyroscope, having motors in 3 axes. As the delivery of this work, I would like to obtain: - Complete technical drawing. - Arduino program, containing comments for understanding the flow. - List of recommended components, cables, boards, motors, other elements deemed necessary for future purchase. The idea is to have two Servo Motors and a DC motor. The DC motor in the center, axis C, image attached, being powered by a current that will pass through a Slip Ring Connector B. Such Slip Ring Connector turns from axis B, which represents the second servo motor, also powered by current that will pass through Slip Ring Connector A, coming from A. The DC motor will be activated as soon as the Arduino is connected to the power source. Servo motors will be driven clo...

The driver is to be used with Solomons hardware SSD1333. It is a 176 x 176 RGB driver with the possibility to be set as 528 x 176 Gray Scale (GS) driver. RGB columns become GS controlled. We use 2 of these SSD1333 chips, one on top of the other, to form an image of 528 x 352 pixels, with each SSD1333 device on its own SPI bus. This means that a full 528 x 352 image needs to be split in two 528x176 to be sent to two different SSD1333 chips hanged on two different SPI buses. We want the driver to be able to write an entire image of 528 x 352 pixels on display, as well as, to control individual pixels, rows and columns, with the intention of ease display testing. Check attached display scheme for better understanding. This driver should provide fps configuration and synchronization between...

Hello, I want to make two weather station based on EPS8266 and LORA sx1278. For this purpose I plan to use this project. 2 ESP8266 and 2 lora sx1278. + 1 ght11 temperature sensor. And maybe one DS3231 to wake up the transmitter to save power. My plan is to mount one lora high above me about 6-7km away in the mountains - that way I will have a direct line of sight with both devices. All the data after receive have to be upload to The Things Network Server

Please see the chat and amplifier that you quoted on. The understanding is that you complete the rask for a fixed price although you asked that a hour rate project is to be made. We both agree that when the design is done that the fee of 450 is to be paid for the task, irrespective of the time spent to complete the task. My engineer will review the schematics and consult if he sees any possible problem on the design. Then you can complete the pcb. Please take care of the component that is to ne used as not to become obsolete.
