This project is very simple and straight forward. I would like to have a custom made numerical keypad key logger that will log incoming data from a 7-pin data ribbon sensor sililar to the one shown in pictures. Data should be saved in internal memory with a time stamp. It should not interfere with ongoing system processes, should save and time-stamp when bottom-right "OK" button is pressed, and should be powered by a 3.6v lithium-ion battery (which will be continuously charged by the system. The unit should also have USB connectivity.

143.461 Modern Multivariable Control
Project One
You are required to control a continuous, stirred tank reactor (CSTR). This consists of a tank into which water flows at the rate of 2 litres per second. There is an outlet valve which you must control and set between 0 and 100% open. The tank has a wall steam jacket, whose temperature you can control – within limits.
The inlet stream usually has a constant effluent concentration of 10 moles per cubic metre. The fluid suffers a temperature-dependant reaction and consumes some of the inlet species .
It is your job to control steam temperature and output flow in such a way as to get as low an exit concentration as possible. You must avoid overfilling the tank and allowing the tank temperature to reach boiling point (100 C). You will do this in VB6 and present a running graph of the controlled and state variables.
There is a wash-down every two hours and the inlet flow doubles for 20 minutes during this time, the concentration of the species in the inlet stream halves to 5 moles per cubic meter.
Data and Nomenclature:
Valve = variable [%]
D = tank diameter = 2m
H = liquid height
I have 29.75 in my freelancer at present. I need money to pay bills and things of that nature. I need someone whom I can send my freelancer money too and they will them proceed to send it to my paypal account immediately. Because you will be letting me use your account, I will give you 5$ as a thank-you. I should end up with 24.75 in my paypal.
If you should try to cheat me out of my money or something like that, I will dispute as well as give you a negative review. I need that money for payments. Thanks.
If I accept you, I will send you an email with my paypal address as well as send you the money that I have.
Youll have to bid thirty dollars, but I will only be paying you the 5$ for transferring. I expect the money to be in my paypal within 15 minutes of you accepting the job.

EDIT: I only have 24.75 at present. Sorry about that. I should end up with 19.75 once transferred. Thank you. Other details still apply.
We need a speech enhancement module for Windows XP/Vista/7 (32/64 bit) for langauge examination. Each candidate wear a headset which has microphone #2 on one ear piece (for recording the neighbour candidate speech and environment sound) and microphone #1 (for recording the candidates own speech). Both microphones #1& #2 will connect to a usb sound card (cmedia 6206 chipset) with two microphone inputs. We need the speech enhancement module can use microphone #2 s recordings as reference to filter these noise/sound from microphone #1s recording so to deliver a clear and silent speech recording for exam assessment.
Since we already made own sound card driver so we just need a module to compare and filter the neighbor speech and environment noise.
Note: environment noise in general not much but neighbor speech quite much because candidates are sitting close.

I need to send a signal (go high/5v) on the parallel port of the xp pc. I have a Access database built that we scan the boxes bar code) and print the label. I can put the code in Access and add a dll driver but I cant get the VBA code to work for me. I will add it to the proper events on the forms and button as needed if you get the code working.
We are going to send the message to a basic stamp and it will advance the belt to the next box and we will start the process over. I would be happy to have some help us use a serial port and communicate data if it would be easier to complete the project.
Special Micro(chip)
Aug 3
Not sure about these categories if this is in the right place, but searching is there already available or is there a possibility to create a chip for tracking things if they are stolen for example, such things as: vehicles, motobikes, bikes, some smaller things? There are available for example GPS car trackers with size about 65mmx45mmx17mm boxes you can put inside your car. Is there any other solution for that, to make any smaller you can hide more easy and anyway can track things with it?
This is just a preliminar search, so dont take any concern about pricing Ive chosen.
I need a simulation Code to check how does a multi hope ( relays ) are affected by the spectral efficiency for 1 hop, 2 hop, 3 hop and 4 hop, example(is the figure below) : used Source Destination multi hop
It should be 10 pages explaining the bandwidth allocation process briefly and how spectral efficiency is an important factor for a multi hop relay network and the process model with equation used to generate the code and the references used for the simulation
Check the attached file its detailed.( with simulation figure that i need the same and some codes)

I have a DC solar pump that operates directly on solar panels at 70 VDC / 13 Amps. I need a power supply design for two different power supplies.
Power supply 1: Output is DC 70 volts with standard 120 VAC input. Output current is 13 amps nominal. The only major consideration is that this motor needs current limiting on startup so if it is powered on from a dead stop it must not exceed 15 amps.
Power Supply 2: Output is 70 DC @ 13 amps nominal from 120VAC input. This power supply will be in parallel with solar panels so it must be protected if the solar panel voltage gets high (can get as high as 90 VDC). If the voltage drops below 70 VDC on the panels Id like this power supply to supliment the power to keep the pump operating steady. As above it must have a soft start and not slam the motor with current. If solar panel voltage is high Id prefer this power supply to use very little power while idle.
Id like the design to be as simple as possible. Keep in mind that this is operated outside so it must not generate lots of heat (no fans) and must have lightning protection.
I am looking for someone to design a circuit and draft a PCB layout (if you can manufacture & assemble the PCB even better).
I want to take the signals from 24 BNC composite CCTV cameras, amplify the signal and output to BNC plugs. The PCB also needs to be able to process the signals into upto 6 outputs. The outputs need to display 4 signal on the screen in a quad formation.
Basically on the rear I need to have 24 video in, 24 video out and 6 quad outputs.
On the front I need controls to select which signals are output on each of the quad displays.
The idea is that I will attach this inbetween the existing cameras and digital video recorder so it continues to record as normal, but then the quad outputs then go to remote screens located around the building. so for example Quad output 1 may need to display cameras 1,2,3 & 4, Quad Output 2 may need to display cameras 1,3,8 & 9.
In sumary I am wanting a PCB with a video amp and 6 quad circuits and the electronic connection between them.
I hope this makes sense but feel free to ask any questions and I will clarify.

Who takes this project must be able to deliver 20 of these PCB boards to start. The PCB board will be small and will run off a 3.7v lithium rechargeable battery. The PCB board will have 10 push buttons connected to it. When you push any of the 10 push buttons the PCB board will log the strokes in the internal memory. One of the push buttons when pressed will time stamp the data. The PCB board will be plugged into the computer by a USB cable to charge the battery or to download the button key strokes that were pressed.
Its very simple. We need someone who can program this and deliver the PCB boards very fast. Hoping within a week or two at max since its a very simple project.
We will use escrow if that is okay with you.
Processor Design Using VHDL
Jul 27
Hi Sir,
My project is to design a Barrel processor (architecture design and coding in VHDL). I have no prior experience in this field. Can you help me out.
I have given a short note on my project below.
I have to design a barrel processor that has to execute only one instruction from each thread at a time for all threads upto N threads. I need to design the architecture for the Barrel processor and has to implement the processor on a FPGA by using VHDL.
So, I have to take a basic architecture of any of the processor and have to modify it such that the processor has N – number of PC,SP,SR,Thread IDs,etc. for each thread. I have to cycle all these registers of each thread at their turn executing only one instruction at a time.
For example Thread -1 is taken and all its corresponding CPU registers are loaded, then one instruction from this thread is executed. Then again Thread -2 is taken and all its CPU registers are loaded, then one instruction from this thread is executed, etc. upto N threads and again its cycled from the first.
Example:
Thread -1 ACC Ro-Rn PC SP Thread ID Flags Thread-status(En/Disable)
Thread -2 ACC Ro-Rn PC SP Thread ID Flags Thread-status(En/Disable)
Thread -3 ACC Ro-Rn PC SP Thread ID Flags Thread-status(En/Disable)
So, I have to design an architecture first and then i have to code in VHDL.
Can you please help me in my project. I have only two weeks left.
Well, i need a simple basic processor design and coding in VHDL that implements the mentioned concept which is enough, with a simple instruction set considered. Its urgent, so can please help me out.
I have attached the idea behind the processor design as for as i got in one of the attached files.

I) programming 3 x types of adaptive-noise-cancellation (ANC) filters on matlab by using built-in functions in matlab filter design toolbox / signal processing toolbox. Example of the 3 x filters are least-mean-square (LMS), normalized least-mean-square (NMLS) and recursive least square (RLS)
ii) comparing the performance of the 3 x filters by applying a sinusoidal wave mixed with random noise onto the 3 x filters, and capturing the signal-to-noise ratio (SNR) / coefficient of the output.
iii) capturing the software simulation output
Need the Matlab simulation code for the filters and the software simulation output within 2 days.
Urgent!
