    This project is two fold as you look at the schematic- piezo and metal tank. The suggest is made of placing a second inductor across the primary of the transformer to improve the driver's efficiency . The value of the inductor is empirically picked to minimize power consumption (it offsets some of the capacitance of the piezo transducer. The optimization need to function with any piezo at the 63kHz range Also we consider a push/pull transformer arrangement driven by a similar microprocessor arranged input. This is typical of higher power ultrasonic drivers.

    We need a 2-3 second intro for our new YouTube Channel “Trash TV”. The intro is a dust bin (trash can) falling over and an old-school boxy tv falling out, and rolling over to reveal a static screen. The TV has two antenna in a V shape, one is a bit bent. The screen flashes into the letters TTV. For the style, we are flexible on this. Not too experienced in commissioning animation, but basically we are open to styles that resemble 90s TV era cartoons. This could be 2D or 3D, however we are not looking into hand drawn or stop motion animations at this time. Our budget is £150.00. If you are interested please send over your website/portfolio.

    This paper embodies the design and development of a compact Coplanar Waveguide (CPW) fed connected ground Multiple- Input-Multiple-Output (MIMO) antennas operating in the sub-millimeter-wave 5G New Radio (NR) n257/n258/n261 bands. The planar geometry leads to a small and compact structure while achieving a wide operating bandwidth, high gain, and better radiation efficiency. The top surface of the antenna comprises a modified CPW in the form of two circular structures that feeds the centrally slotted circular patch. The single antenna structure is arranged in a rotational orthogonal manner forming a 4-port structure. The ground plane on the bottom of a 4-port structure is connected using a circular ring which is carefully optimized for achieving isolation level...

    A L-band radar operates at a carrier of 1 GHz. It observes an aircraft moving through space in a straight line at a speed of 300 kmph. The aircraft approaches from the east, flies directly overhead of the radar at an altitude of 10 km and continues to the west. Assume the radar antenna tracks the aircraft so it always appears in its beam.
