    I need a pcb coil electromagnet designed similar to Carl Bugeja's Flexar pcb actuators (you can find them on his YouTube channel), but I need mine to be about 8 cm in outer diameter and it needs to be powered off of 3.3/5 volts and must produce a magnetic field strong enough to move ferrofluid in a display.

    The device is an ion exchanger. It is therefore used to extract ions from media, in this case water. This can be ensured, as long as the device has “space” for the ions. This unit is reprocessed with acids and alkalis after it arrives at the factory. This process lasts from several days to several months, so all materials worked with should be fully resistant to the corrosive and abrasive effects of said media. The device already exists and is now to be extended with useful features for the plant and customers. These various sub-items are assigned as one package, various packages, or separately, depending on competency. The developments of the sensor technology, as well as the processing of the electrical signals resulting from this, are the priority tasks. For further in...

    Need design and working prototype of Arduino or ESP32 for use as programmable/adjustable constant voltage and constant current regulator. Also, output will need to be Transistor/FET controlled for use as pulse out. Circuit should be capable of being powered by typical usb from laptop or alternate power supply, but built using usb-c preferably. Input power should range from 5VDC to 30VDC or higher. Adjustable output voltage up to 30 VDC minimum with 16 bit resolution. Adjustable output current up to 2 amps minimum with 16 bit resolution. Preference is to have a socket for the Arduino (embedded Bluetooth and UART) or the ESP32 (embedded Bluetooth and UART) in the case of failure. Drawings, schematics, and GERBER files should be included as well as a bill of materials, along with two worki...
