    The project consists of two boards 105X80mm each that will be stacked into a single enclosure. The first board has a three-phase metering chip (RN8302B), three relays, a SIM800C GPRS modem, and several pluggable terminal blocks. The seconds board has an STM32 QPF48 MCU, three optocouplers, two digital isolators, an RS485 transceiver, B0505S Dc/DC converters and 2 LDOs. The two boards are connected by a 30-pin, 1.27mm pitch, flat cable. Schematics in Altium Designer format are complete with footprints assigned to components and footprint libraries ready. The board mechanical DWG file is also available. Design shall adhere to the manufacturing capabilities of JLCPCB for two-layer PCBs. Deliverables: two-layer layout files of the two boards in Altium Designer format.

    Design circuit You may use Multisim Construct a single phase, one-pulse SCR battery charger in Multisim. The same basic circuit as in section 1 above can be used, but replace the diode with a SCR and include a 340VP : ≈ 200VP (depending on your student number) step-down transformer between the ac supply and the SCR. Implement your circuit in Multisim using ‘virtual’/ideal components. Also add a 10-V firing/triggering pulse via a 10-Ω resistor to Gate and Cathode. You must have some form of delay in the pulse to fire at a certain angle Simulate typical output waveforms for the circuit (choose a firing angle α). Show voltage as well as current – and use a current probe to send the signal to the oscilloscope. Briefly discuss the waveforms to summarise t...

    Not processing more proposals. Follow the Sun is a 50' Solar catamaran. The boat has 2 motors, one in each hull. The motor forward speed is controlled by a 0 to 5v input signal. The motor backward speed is controlled by setting reverse (close contact) and 0 to 5v input signal. Turning is accomplished by reducing the motor speed on one side. Via throttle input or by autopilot command) The requirement is for a throttle circuit that will allow manual and autopilot control. Please contact me for further detail.

    I am designing two PCBs (a RF emitter and a RF receiver) and I would like to find someone to give me a hand with it. A summary of specs is presented below: - The emitter (Tx pcb) it is like a keyfob. It should incorporate an encoder (HT12D or similar) along with an RF emitter IC and a PCB printed antenna. This board will be powered with a coin cell (3V). There will be only 2 inputs coming into the encoder. - The receiver (Rx pcb) should incorporate a decoder (HT12E or similar) along with a RF receiver IC and a PCB printed antenna. This board will be powered with a single LiPo Battery (3.7V). There will be 4 outputs. This board should also incorporate a LiPo charging management circuit (TP4056 + DW01 + FS8205) and a DC-DC boost IC (MT3608 or similar) since one of the outputs requires 12...
