Static Voltage Stabilizer is an IGBT based PWM type buck-boost voltage stabilizer which has tight regulation and fast correction speed which is impossible to obtain using conventional methods such as servo voltage stabilizers, SCR / triac type stabilizer, relay type stabilizer etc. This is an SMPS type voltage stabilizer for mains voltage (AC input and AC output). This is a new switching topology ...

i am looking for a expert in SystemVerilog and UVM test environment for RISC-V processor.

** Please download the attached file "Job [login to view URL]" for a complete explanation. ** I am looking for an electronics engineer to advise me on how to optimize the RC network to get a perfect “carbon copy” lag signal. It must work no matter how long the LOWs are. I suspect my RC network could be optimized to operate better or maybe there is a semiconductor that can r...

My name Kavita Prasad and I am in the early stages of setting up my business. I am looking for someone who can help me add a battery charger (for phones) into the lids of my water bottles. The bottle is cylinder in shape and will need to have the longest battery life possible and charge the phone fast without damaging the phone. It will also need to be water proof and not contaminate the water in ...

Its a small circuit design schematic project. With ardunio uno 3, LCd16X02 LCD, I2C LCD Module, 7 X TCRT5000 module. I am also uploading a image file of circuit I made with [login to view URL] I just need it made in schematic choose any software, you like eagle etc.. Thank You

I need the designs for a compact bluetooth device that will fit in a small housing. Footprint for the PCB will be provided. The device should use an Apple certified Bluetooth controller. More details will be provided when you apply. Thanks!

I need to produce a device that will monitor water flow out of a tank. This will be for a boat. I will want to use a water sensor inline with out pipe of the tank. You will initially set the tank capacity eg 100 litres. Then the display will monitor the water passing thorough the sensor and decrease the display. Ideally the monitor will be on a remote cable and backlit. An audible warning could b...

Need to make simple PCB layout design, from ready schematic diagram. KiCad, Eagle or Altium. A basic entry-level task for Electrical Engineers who involved in various power-supply electronics and LED lighting applications. I consider it as micro project.

hello i need help asap with circuits 2, please text here if you know the concept

Need to build a switch-mode power supply that drives a ~1Mhz H-bridge, all powered by a AAA battery. Specifically, I need a tested circuit design that will work to drive this using small SMT components. Using a MIC4606 H-bridge to drive 200mW.

I am developing a device to respond to acceleration. I need help to design a circuit that is cheap and compact and can filter out vibrations.

The project concerns the design of a data acquisition module for LVDT probes. The module uses the PGA970 chip from Texas Instruments and must also have the relative signature that allows the management of different types of probes, with different values of sensitivity and connections ( 2-4-5-6 wires ). The project foresees the realization of the electronic diagram and the realization of the PC...

Hi, I need a schematic/PCB design that will convert 24VAC to 3.3VDC. AC/DC should be robust and be able to handle AC spikes and most important protect the 3.3VDC microcontroller/circuit. The system will be used in homes on the low voltage 24VAC. Design should be done in Altium.

I am starting a micro brewery and have designed a PID control system to regulate temperature throughout the process. Although I have a background in electronics it was a long time ago and a lot has changed. I would like to talk through my design with someone who has both electronics and electric knowledge in order to advise on my design.
