    I am wanting a Server Based Block Grabber for an android program called Amazon Flex. Blocks are released by their server and I am trying to be able to grab them before they get out to other users. You will need to install a proxy server onto a VPS. You will need to have this connect to the server to access the blocks for the Flex program/app. I need it to check for blocks between 10-20 times per second. Then when a block becomes available I would like it to be grabbed from the server to where an Android phone can then accept. Ask me any questions that you might have.

    I have designed a PCB that is powered by 12v. It powers an esp32 cam, attiny chip and PIR sensor with a 5v buck convertor. I have added a circuit to the board for a "dark sensor" utilizing an LM393 chip, that will allow the main 12v current to flow when sun goes down. I need someone who is an expert with circuit design, to check and verify the "dark sensor" portion of my circuit, even though this is considered a relatively basic design.

    Consider the sequential circuit implementing serial addition built with two shift registers, a 1-bit full adder and a D flip-flop (Figure 6.5 in Morris Mano & Michael Ciletti, Digital Design). Design and implement in Verilog a 4-bit version of this circuit. Use the behavioral implementation and make the following changes/additions: 1. Create a logic diagram of the circuit. Use Figure 6.5 and update it using the structure of the behavioral model (add a 2x1 multiplexer and parallel inputs to the shift registers). 2. Cleate a logic diagram of the shift register with parallel load as implemented in module shiftreg (block level multiplexers and D-flip-flops). 2. Implement modules shiftreg and serial_adder at gate-level using gate-level D-flip-flops and 2...

    This project requires knowledge in power relay physics and arc suppression (TVS) techniques. We need a circuit to wrap around a latching power relay to minimize internal relay arcing during operation (make/break) for extended operational life. There are many conceptual ways of doing this such as snubber and varistor approaches, but we need specifics on products to use that are available today and their configuration. The relay in question is rated for 250V, 120A but we are operating in a 120VAC nominal environment with at most 60A full load. Datasheet of the relay can be provided. Expected life of the application/proposed solution is ~20 years with up to 10,000 operations over the life of the product.
