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 ...

We have customers that will want a shoe shine. They will sit on one of those chairs to have a shoe shine. Each treatment is about 10-15 min. There will also be a camera on top of the chair. At the end of the treatment (shoe shine), the customer will pay the operator who did the shoe shine for him. We will ask the operator to key in in the store system the transaction and issue a ticket At the end of the day, to cross check that the operator did not do any treatment without declaring it (ie stealing), we will cross check number of transactions entered in the store system (that issued at ticket), the number of times the seat has detected we had a customer for treatment, and the number of customers detected via the camera. We are looking at an electronic application that can 1) Count the number of customers who spent more than 5min on a seat 2) Detect from the camera images the number of customers who had the service during the day 3) Notify the store owner if any discrep...

We are implemeting CAD Standards in our studio. We currently have AutoCAD LT, and need to streamline toggling layer states for working on our architectural plans. In my previous firm, we had a full AutoCAD license, and had a Macro/ Lisp custom toolbar ribbon that we loaded for customization. My understanding is that this is not possible with the LT version and am researching what the best alternative is. We currently create Layer States for individual projects which is time consuming and inefficient in a growing studio and are open to any proposed solution similar to a custom ribbon. We can provide a spreadsheet and a CAD drawing that identifies all layers. The spreadsheet will also identify which layers should be turned on or off depending on which plan we would be working on. We would also need to lock all off layers in order to enforce standards. We will need to have separate layer states for the following plans. - Construction Plan - Reflected Ceiling Plan - Electrical Plan - ...
