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.

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 - ...

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...

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!
