Electrical Engineering jobs

Electrical engineering is a branch of engineering that involves the study of electricity, electromagnetism and electronics. An electrical engineer knows how to deal with a host of electrical appliances and devices. To ensure that your electrical device is compliant with the set standards, you need to hire a professional electrical engineer. For this, all you have to do is hire a professional electrical engineer. Once you have an experienced electrical engineer onboard you can hope to add a fillip to your business.

    we have several PCB boards which were detected as a source of 100MHz emission in the lab. We would like to find the source of this signal with our spectrum analyzer(Siglent SSA3032X). we have probes and did some tests already, but it's hard to find anything useful since it's a new experience for us and we do not even know where to look. We need someone who has BIG experience in such troubleshooting and be able to spend 1-2 hours with us debugging the board and guiding us over skype video call. You should really teach us the technique of finding EMI issues and find the problem to get payment.

    I work at a crash test facility and we use a lot of piezoresistive accelerometers. That being said, we need to be able to quickly check the functionality of the accelerometers before we put them in a car for a test. So I need someone to build a handheld device that can measure and tell me the resistance on both sides of the wheatstone bridge inside of the accelerometer.

    Electronic Timer Design 6 days left
    VERIFIED

    NDA required. The device will be 8" Long x 2" Deep x 2" Height It is a timer actuated by the removal of an object on the surface of device. When object is placed on device, timer starts. When object is removed, timer stops and resets. There are four independent timers on this 8" long device. Each 2" x 2". So, place the object on the device and led illuminates red. Timer starts. When timer reaches interval, LED illuminates green. This indicates the timer has reached the set interval. When object is removed from device, the LED turns off. When device is placed back on device, timer starts over and LED illuminates red. A small button in bottom left of 2x2 square can reset timer as if the object was removed. Intervals can be adjusted from 1 minute to 72 hours with a sliding bar. Each of the four timers can be adjusted independently. Low battery indicator light required. Power on/off required. Need the electronics for above device including PCB, schematic, LED, battery, etc. Need the enclosure design and all mechanical

    Important: • Please create a new assignment folder in your working directory for each assignment, and a new problem folder in the assignment folder for each problem. • Please backup your files in your own USB drive or your own network drive at the end of each class because the workbench computers may be reimaged without prior notice. Problem 1. UART serial communication with interrupt. • Follow “[url removed, login to view]” to create a new CCS project with the name “Lab3_1”. • Delete “main.c” if you have generated the file automatically. • Copy the source code “Lab3_1_main.c” into your project folder. • Make sure your LaunchPad is properly connected to PC. • Launch the Windows 10 Device Manager – Ports (COM & LPT). Look for the line showing “XDS 110 Class Application/User UART”. For example, in my computer it is COM4. It might be a different number in your case. Write down your Application UART port number: COM______. • Lauch the software PuTTY. Enter the following as shown in the image, Connection type: Serial, Serial line: COM4 (which should be your COM port number), Speed: 9600. Click the Open button. 1 • In CCS, build, load, and run your project on LaunchPad. • Bring up the PuTTY window that you just opened, then type on the keyboard. While you are typing, you should see the letters you typed in the Putty window have been received by the LaunchPad and printed in the Console window in CCS as shown in the two pictures below. 2 • Explain the code line-by-line in your report. • Once the UART communication is working as described in this problem, you can simply use the following line in your code to display any messages on the PuTTY terminal window to help you with the debugging of your code: uart0_transmitStr(“You can have any text that you want to display on the terminal!”); Problem 2. UART serial communication with polling. • Create a new CCS project with the sample code “Lab3_2_main.c” • This code uses polling method to receive from UART. Compile and run the code on LaunchPad. • Study the source code and explain the source code line-by-line. • Make the following changes in the source code, then compile and run the program again: o Configure DCO frequency to be 12MHz. o Configure UART0 baud-rate to be 115200. (You will also have to change the baud-rate in PuTTY in order to communicate with LaunchPad.) • Explain your source code line-by-line in the report. Problem 3. Glitch filtering for user button S1. • Create a new CCS project with the sample code “Lab3_3_main.c”. • This sample code implements a software glitch filtering for user button S1. • Compile and run the program. Study the source code. • The user button S2 is connected to P1.4, which has glitch filtering capability built-in. In order to enable glitch filter, you will need to call the following function when configuring the GPIO port: void SysCtl_enableGlitchFilter(void); • Modify the source code to implement the following features: o Click button S1 to double the LED blinking frequency. o Click button S2 to decrease the LED blinking frequency by half. 3 o Define a minimum (2-4 Hz) and a maximum (24 Hz) blinking frequencies to prevent the blinking frequency from being increased or decreased indefinitely by user. • Explain your source code line-by-line in the report. Assignment Deliverables: • Compile your report with pictures, plots, and the codes that you have written or modified. • Explain in detail what you have done, why you have done in that way, and what you have learnt. Follow the report format outlined in the Introduction lecture notes. • Printout of your source code should be attached to your lab report printout as appendix. If your source code goes beyond two pages, please only print the part of the source code where you have newly written or modified.
