The job is to review the PCB layout in ALTIUM designer software. You have to give me a review in the form of word file mentioning all the mistakes you found in the PCB layout according to the schematics. You do not have to correct those mistakes but just to mention and point out those mistakes and any recommendation you want to give in a note pad file or word file. Word file will be better so you can paste snap shot of the PCB layout where the mistake is present. Best Regards Faizan

Please read carefuly 1) CUT AND PASTE proposals will not be considered. So dont bother. 2) Type "locked and loaded" as your first line of you proposal 3) Add links to any portfolio projects (make sure they are LINKS and not downloadable files) 4) Briefly explain your related experience (1 or 2 sentences) 5) Briefly explain any strategies you might have to achieve the goal (1 or 2 sentence) 6) Your proposal will also follow this numbering format. We are looking for an expert growth hacker/marketer/webscraper to help with building a community for our commerce site. Introduction Our vision is to build a community of curated "makers" who use CNC (Computer Numerical Control) mills to create beautiful pieces of art. CNC is another form of 3D printing, instead of printing material, you cut it away. See here:   [obscured]  /1LZ3tJb So you take a sheet of wood/metal/plastic and can turn it into anything you can design. Here are some examples.   [obscured]  /searc...

I have 3 phase 480v electrical into my property, I need to run power out to my site 850 feet away. I'd like to have a 100-200amp service of 1 phase power at the end of the 850ft run. This will be direct burial cable and I would need the EE to look up the Oregon or County specs to make sure the cable selected is suitable. In summary: 1. Size wire according to load and length and 3-phase. 2. Select wire from a discounted source ideally, like ebay 3. Size transformer for 3phase to 1phase 4. Select transformer.

The objective is to design and fabricate one or several circuit board(s) capable of collecting multiple vital signs (ECG, SpO2, Temperature). The design can be a new design or one that is based on an existing reference design if the requirements can be met. If a reference design is used, schematics and demo software/firmware will be provided by the freelancer. The requirements are: - Capable of measuring ECG, pulse oximeter (SpO2), and temperature - Use an embedded 32-bit microprocessor with DSP functionality - Data collection of ECG and SpO2 must be simultaneous or with a low, deterministic latency (<1ms) between ECG/SpO2 samples - Sampling of ECG/SpO2 should occur at a rate higher than 100Hz with a good signal-to-noise ratio - Communication over USB/RS232 to a PC host - Onboard storage for at least 10 seconds of ECG/SpO2 data - Powered by a +5V DC power supply. Preferably a USB port. - A touch or infrared sensor for temperature - Firmware/software program demonstrating the fu...

This job is a large project which can be executed by a single highly competent engineer if required. We realize that this project description falls short of the requirements and will serve as a preliminary requirements. 1) BACKGROUND One of our clients is using a variety of heavy duty machinery to perform testing on packaging. The packaging may, for example, consist of oil drums, plastic drums, tin cans and other materials. These packaging materials are certified by this packaging centre through the following tests (Each test below is performed by a machine in question) a) Load Press - The machinery here performs a "press" upon to a package to see if there are any stress faults or breaks in the package - Machine puts up to 5000kg pressure b) Holding Pull - This machinery tests the plastic straps that are used to "wrap" a package across the horizontal and verticals. c) Hotroom Press - This room consists of heaters and systems that are designed to place a sma...

Since I'm often overloaded with work, I am looking for a work buddy. Someone I can trust, and share future projects with. I am very specifically looking for someone living in Davao Region, Mindanao, Philippines. I need to travel several times per year to Tagum City for personal reasons. It would be great to get in contact with some engineers in this area, so we can work together on projects more efficiently. These are the skills I'm looking for: - Circuit Design. You know how to desing electronic circuits (analog and digital), and have preferably some experience with a design program like Eagle, Target3001, ... (or anything similar). - Embedded Software. You know how to program a microcontroller (preferably in C). I myself have experience with 16-bit PIC microcontrollers and will soon learn how to use the Cortex M7 (from ST Microelectronics). Experience with one of these would make our cooperation easier. - IoT (Internet Of Things). For future projects, I will need to focus on micr...
