Hi, I have with me a PCB design created for me, but I wish to have an consultation with an expert on the design to ensure it is robust enough before I take it to the Gerber design stage. The design is for an Emergency light PCB control which will switch to battery mode when the supply has been cut. Let me know should you be interested and I shall revert with more details. I am fine on hourly rate, but I also wish to chat online and discuss to go thru any doubts. Thank you. Lee Han Pin

My Research topic is:Two dimensional modelling of sand production, using Finite volume to solve the governing equation and then use C++ to program.A C++ Visual code would be used to solve a 2Dimensional Navier stoke's equation in order to predict the critical drawdown pressure. I have been able to obtain the governing equation and discretise using finite volume.I have been given a C++ Visual code of 2D Full Navier stokes equation comprising of the Energy equation,Momentum and Pressure Equation which i have to solve for a flow in a pipe and obtain the Temperature,U and V velocity, temperature distribution and then the pressure distribution in the pipe. I wish to check the functionality of the code by making it obtain the required result with the various boundary conditions imposed(Top and Bottom -Insulated, Left-Dirichlet, Right-Convective).After solving the Navier stoke's equation for the above problem , i would also need to incorporate the code to determine the critical drawdown press...

Hi I have a small water valve that is being fed 14.5 dc volts as read on my meter to open a small solenoid to flow water. When Idle the circuit has 5 volts on it and is being monitored by the computer. I dont like the valve. I need to use a 120volt ac valve to flow the water. Can you provide a simple circuit that can detect the 14vdc flowing to the bad valve and turn on 120vdc from a wall socket plug onto a small 120ac volt valve.

Parametric analysis of Solidworks flow simulation are to be carried-out using flow simulation API, the main idea is to edit already generated codes in VB 6.0 into VB.net or C++ (prefeably C++) , a plugin in terms of fluid codes (using codes already generated in C++ for navier-stokes momentum equation) should be embedded into the solidworks flow simulation environment), the VB 6 codes are able to do the following: 1. Change different impeller types used for the study 2. vary fluid height in the mixing vessel 3. Varying impeller rotational speed 4. Vary impeller distance from the bottom of the mixing vessel The plugin codes are written in C++, and its untended to be introduced into the mixing vessel as an external fluid and different results ar intended to be generated from the simulation that would determine which impeller gives better homogeneity and at what impeller distance this should be achieved. My system config and software : Win 8, 64 bit, solidworks 2015 and MS visual st...

I am designing a universal card. See   [obscured]  /wiki/Universal_card. I would like to enable it to work in a wide range of readers. But as a small company it is expensive to set up an extensive testing program to do this. I am looking for an electrical engineering consultant with in depth knowledge about dip and motorized magnetic stripe readers that could guide us in our development. English speaking a requirement.

Hi, We need very specific device manufacturing (prototype + logic). Size of device must be not more then iBeacon (but here can be any server device), when some one near range of device (range is 2-3 metres), device must catch it (i mean identify it) and send signal to WiFi router or something else. Mobile Devise can be Android / IOS and we are not able to install any software to device. Probably you can catch BT or WiFi or any else signal from device. Share your budget. At first we need ~ 100 devices. Thanks!

I will like a very good product designer than can create an innovative portable salon sink which can be easily carried around and doesn't take a lot of effort or time to setup before use. It has to be portable and lightweight, easy to setup, and is easily collapsible into a rollable case to make it easy for transport. The designs I have seen are harder to use for freelance stylists because 1) the sink takes some time to setup so has to have been setup prior to the client visit 2) once the sink is setup prior to the client visit, the product becomes bigger and harder to transport as it is now bulky 3) there is no case for the sink in its pre-setup of post-setup phase so there's no sleek/professional way for stylists to transport it into clients homes. The sink design should also factor in the need to retrieve water and to drain out water. The design of the sink, most particularly of the base of the sink, has to be innovative in order to overcome these challenges and so the product de...

We need a Radar system developed that is camera based. The project will require the freelancer to build a pan, tilt and zoom solution+ the detection and tracking software. Operational Specification 1)System scans the sky looking for planes (Any Kind) 2)Detect at least 10 planes at the same time 3)Assign Ids to all detected plane (  [obscured]  /watch?v=LNaL58GRou4) Something like this but for the planes. 4)Track the plane selected by the operator 5)The software needs to calculate the GPS location of the plane + altitude + Speed + Distance of the plane from the camera + expected path 6)The system will need to identify the planes by make and name 7)Have a traditional radar GUI + Show the plane( that is being tracked) on Google Maps 8)Detection range of 5Km 9)Required accuracy rate of +-10m

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.
