    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...

    The Sketch needs to scan for specific BLE devices and then display a signal strength via a coloured 5 led bargraph, play a beep, and show accumulated points for the time spend within the vicinity of a found BLE device. Required deliverable for this project will be a single Arduino Sketch. This project is a follow on to a previously completed Bluetooth BLE Scanner MIT Inventor App (see project brief attached). The APK can be found in the project files on Freelancer. The objective of the MIT Inventor app was to prove that the BLE scanner concept would work. This follow-on project will to be to extend the concept to an Arduino Nano Microcontroller. See attached PDF for full project description

    I need to design a wireless battery charging like one of those show in attached pictures. In 1-2 pictures you see planar antenna for wireless power transmission and cylindrical antenna in the receiver section: this is the first possible solution. Second solution (3-4 picture) is to have both cylindrical antennas to have this charging system, anyway the antenna in RX section has to be cyclindrical for mechanical reasons. The RX antenna has maximum lenght of 40mm and inner diameter of 22mm. I need to have a charging minimum current of 1A. Distance between two antennas is about 3mm and there is nylon PA12 between them. In TX section we have not particular constraints in the shape of antenna, you can design rectangular plane antenna too. We have 5Vdc 3A current in TX section. I need to have d...

    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.

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.

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...

The machine should not use any hydraulic and pneumatic system for Operation. We would be able to give input to the machine through the push button available and also directly through the computer or data stick in case of bulk requirement ( different cable length). If the machine can itself take different cable ( sq mm) and cut it into desired length as per table or input provided in bulk would be great.
