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

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...

Hi, I have at a fair a device that is able to talk to centralised Heat&AC systems (like the ones that you find in hotels) and to control remotely temperature etc.. The device is marketed as a power saver due to the fact that uses ultrasonic sensors to detect the presence of people in the room and shuts down heat/AC or reduces it based on the setting chosen. The device is powered and uses power line network and a proprietary protocol to record power saving (the delta between the power reduced since the absence and what it would have used in power if the device was never in place). I would like to produce this device, right now this little device (15cmx10cm) can not be bough, so I would like to create one to propose to hotels etc... Would you be able to help? How would that work? I am a software person and never tried HW/Electronics before, so I am sorry if this might sound a bit foolish, but I can assure the project is serious and I have intention to find the right partner ...

I'll need to measure temerature from 12 points through non-contact temperature sensors. Once the temperature is readed, the data has to be saved in a memmory card. Ideally, the sensors will be reading and saving temperature, at least, every 0.5seconds. The idea is that later I can plot temperature vs time. The freelancer will have to prepare a tutorial on how to do this and must cover all the aspects so that someone with little knowledge can buy its own sensors and do it. That includes the code. I hope to hear from you soon. Cheers P.S: I was thinking about this sensors:   [obscured]  /products/9570

Hello, I wanted to know if you could help me. I'm designing a new product that needs an internal power generation. My research has steered me towards "disc type axial flux generators /motors". See attached sketch idea. Basically I need a test bed to prove theory I have based on the contrasts that are given. I can't fully describe the entire design but part of it needs to generate electricity and output it to a outlet, which kind of mimics a typical low voltage wall outlet performance you would find at a normal house. The initial device constraints was to have a cylinder can design with a max diameter of 3.5 -5 inches, and have the device be very light weight, and requiring very little force to spin the axial flux inside. I have not specified a height yet this is all a idea in testing phase. What I'm requesting is a design or instructions to create a test bed in my shop and so I can build and tested it, the shape and design are critical. This is a generator, I will ...

Dear Elancers, I'm was looking for buying a Honeywell resistor board (Honeywell-221508A) but unfortunately I couldn't find it and it's out of stock in most market areas. So I decided to make it by my self which I think it's not very complicated. It's just an analog card with mosfet. I'm looking for someone who help me for building this resistor board and give me some advice for the board. Please pay attention that I only need your advice and help for this so it's not a hard job. in the attachment you will find the pic of the board. Looking forward to hearing from you, Thanks,

That is why I am making this query. This will be our last improvement (I said that before) so it needs to be done correctly. Note: I have several versions in the worldwide market since 2008 so I know EXACTLY what my costs are. Any/all bullshit will be ignored. I wasn't born last night.
