If you are a hardware engineer, this is the task for you. Use your creative skill to come up with a way to program or manage any vacuum pump to have some intelligence. The vacuum pump can be programmed to pulse, meaning you can program it to increase slowly, wait for a short period, then decrease slowly, wait for a short period and then increase slowly until it reaches the highest vacuum level. Step 1: Convert any aquarium(fish tank) pump, whisper pump or refrigerator pump into a "vacuum pump". You can search for any of these on ebay or amazon. It costs anywhere between $10 to $20 USD. If needed, I can provide instructions on how to modify these pumps into a "vacuum pump". It is best to create an "add-on" device that can work with any existing vacuum pump. This way, we don't need to spend huge amount of money to manufacture the vacuum pumps from scratch. Step 2: Use whatever suitable programming language to create the below User Interface to acce...

We need a custom built electrical switchbox. We have a computer control which will control this box with 12V DC signals. This box will have two inputs: AC power and four 12V DC signals coming through an RJ45 terminal. The outputs are four pairs of switched 120V AC terminals for controlling AC appliances. The appliances do not need to have AC sockets, as they will be wired directly by hand.

Seeking an EE to be able to develop a concept for a new product: Proof of Concept development - The product will require the design of a small circuit board using commercial and readily available components to implement the functionality. Design of the low voltage (battery cell powered) circuit along with a construction of a simple breadboard will be required to display the functionality.It is anticipated this will need experience in analogue and digital (simple) circuitry to make this happen. The purpose of this development/breadboard is so our client can display and demonstrate the methods of operation to their potential investors. Ideally the implementation should be minimal and cost effective to achieve this with a quick to turn on developing the prototype/breadboard Experience required : Analog and digital simple microcontrollers and associated programming/debugging Visible LED and IR LED and detector experience Chip accelerometer and/or inertia detection

The CAT system should test the response of the following types of filtering circuits: Low-Pass and High-Pass. design low-pass and high-pass filters. along with a copy of the frequency response shown in p-spice. The Analysis routine should determine the following parameters: Maximum Gain and Frequency, Minimum Gain and Frequency, f1 or f2 values, bandwidth, and Filter Type (LP or HP). The data must have only one maximum point and if there is an f1 point or f2 point, there can be only one of each, not multiple f1 or multiple f2 points. The Analyze routine needs to include linear interpolation for finding the f1 and f2 points from the adjacent data values. need this in hour or two . this is a small project can be done within an hour google already has low and high pass .but not with two filters so lets see

We have a PCB layout job that will take an existing .pdf schematic, adjust circuit design based on red line changes (mostly deleting a few sections) and then layout a new board based on a .dxf file of the board outline that includes all critical placements. the board is approximately 4" square and will be populated with about 80 - 100 components. We will order and assemble prototype boards here in house. This job may actually be two very similar boards with the identical schematic design. We prefer the Use of Eagle as it allows the most flexibility for us.

Basic circuit to convert the voltage output from an Arduino controlled MCP4725 DAC outputting a voltage from 0-5V DC to a signal voltage of -5V DC to +5V DC. Therefore 0V = -5V, 2.5V = 0V, +5V=+5V This is for motor control so a clean signal is required and possibly a 0V start up output but this is not essential.

I have 3 k files which the simulations already finished. I need to compare the graphs of all of them. Also I need to find the strain energy release rate of those composite laminates and compare them. So all I need is: -One graph that has all the plotting of force vs displacement in order to compare them with each other. -One graph of all the plotting of effective energy release rate. (as attached in the paper) -calculations of mean values of normalized compliance and Gic I attached a paper which is my main reference for this. Please take a look. All the above are based on this paper. I need this very quickly, as soon as possible.

PLEASE READ THE ENTIRE LISTING FOR CONSIDERATION Looking for someone with significant Civil Engineering experience. PE license not necessary but the ability to take a project from concept to completion with minimal instruction/supervision is a huge plus. Familiarity with drainage reports and stormwater also a plus. The ideal candidate has their own licensed version of Civil 3D. Must be able to get work done quickly and follow CAD standards. If you do not have significant experience using CAD on construction projects in the Civil field, please do not apply. PLEASE ONLY APPLY IF YOU HAVE CIVIL ENGINEERING EXPERIENCE. I am not interested in architectural, structural, or mechanical work. You must have experience with Civil Design and Engineering and be able to show projects you have done.

Hello, I need a report and/or spreadsheet that outlines the majority of fitness bands on the market. What I need to know are: Manufacturer Model Blue Tooth 4.0 ((BLE) ? Acceleromter/brand/device Gyroscope/brand/device Magnetometer/brand/device Android Compatibility iPhone Compatibility Software API that allows access to streaming of raw sensor data? If yes, what is the max sensor streaming rate? (>50Hz required) Average Price Many bands such as Fit Bit, Jawbone, Adidas X_Cell, etc provide higher level software API's with no access to low level sensor streaming data. The Android Watches, Microsoft Band and Pebble watch do indeed provide for this. Please help me find low cost fit bands that provide access to low level sensor data as well as the additional information outlined above.

As you know, big box stores demand very low cost electronic gadgets. Often consumers will enjoy using an electronic gadget for a few minutes, and then will discard the gadget. Dichroic lcds require voltages > 9V. 9V driver chips are expensive, and chips suitable to drive 3V TN lcds will not handle voltages greater than 5V or 6V. I want you to write up a basic BOM. After I approve BOM, you can also make the schematic and gerbers. I need you to be creative, to "put your thinking cap on", and suggest a VERY LOW COST pcba to drive a single dichroic lcd pixel off and on, like a simple flasher circuit. The precision of the timing of the flashing off and on is not important. Square wave is best but not required. Direct drive is OK, but a multiplexing rate of 16 flashes per second or 32 flashes per second reduces battery consumption substantially. If a pcba with direct drive is lower cost than a pcba with multiplexing, I would prefer a direct drive pcba. For example, in...
