Rekrut Circuit DesignersI want a bridge board to connect a 4.3 inch 40pin 'standard' LCD to a smartphone. Optionally you can suggest other 4.3 - 4.5 inch display(if so I need to check width and height first). On the LCD side: this 'standard' 40 pins are the ones used by companies like [login untuk melihat URL] and other chinese brands for Raspberry. One of the part #s is 043145C0-40-N. They are sold ...
Suggest a conceptual design of variable frequency ultrasound transducer in a range 20kHz to 10 MHz. The job is to suggest a high-level concept and a solution to how an ultrasound transducer can have a variable frequency. Usually, an ultrasound transducer operates with a resonant frequency. The goal is to overcome limitations with a simple and elegant engineering solution.

Design and build a PCB. Powered by 230VAC (e.g. using encapsulated switching mode power supply to 5VDC). DC output of SMPS powers battery charging circuit for on-board battery. Battery powers circuit (acts as UPS) if/when input VAC fails. The circuit (powered by on-board battery) has two functions: 1) detect DC output from SMPS. Buzzer sounds if input VAC (or SMPS VDC) d...
