    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...

    Generate new code for an ARM series MCU (likely the ATSAME70J19B). Two processors on two separate PCBs will monitor GPIO pins for digital and analog inputs and comparing those values to alarm set points and annunciating alarm status via LED outputs (about 20; green=good, red=alarm). The two micros will communicate between each other via serial ports (converted to RS485 via single chip convertor). A couple other features such as detecting physical key turn-on and time-out-timers will be required. PCBs are being laid out now. Coding should start right away. Will include Ethernet port and Simple GUI for viewing/clearing alarms.

    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...

    1. This is a project based on a circuit board. I will provide the schematic diagram later. In the picture you see a BLE module, but I will try to add one more. 2. The connector on the upper left has 4 input, 12v, gnd, CAN+ and CAN- 3. The 4 connectors on the bottom is pretty much the same, it control 4 identical components. Each connector has 6 wires: Gnd, two output for dc motor, ws2812 data, 5v, and a switch trigger. 4. Whenever a switch is pulled to ground, it will trigger the motor to pull for 1 second. 5. Whenever a motor is pulled, the ws2812 will start to light up. 6. After 20 seconds, the motor should reverse back. And the Ws2812 strip should light off. 7. Whenever a certain CAN signal is received (will be provided), all the 4 motor should pull for a second. All 4 ws282 strip will...
