GSM Magnetic Stripe Card Reader

I am looking for someone with high experience in GSM/GPRS and SMS data transmission. I need the qualified bidder to build a GSM Magnetic Stripe Card Reader. After the card has been swiped, the data has to be sent via the GSM module to a phone number of my choice.

Also most importantly the reader must be able to read interrupted swipes. (If the card is swiped half way and then back out and then forward in a fast,slow or jitter motion), the magnetic reader can still read the data from the card.

It also must have a long life rechargeable li-ion battery. The device is required to be portable, so the PCB is required to be as small as possible.

Thankyou.

Flow Chart (Microcontroller)

I urgently need a microcontroller flow chart to be done by tomorrow. Here are the details. If you are familiar, this should take no longer than 0.5 hours. Seriously:

Basically, I need a heat blower to be located at the aircon outlet. The heat blower will adjust the temperature with the room being cold by default. The chart should comply to the following:

1. Set temperature for room
2. Sense the room temperature
3. If too cold, heat blower increases heat
4. If too warm, heat blower decreases heat
5. Back to sensing room temperature

Thats all

Hi I need a simple switching device that is triggered buy and audio spike of sound

I have a trifield natural em meter

An iPhone that is programmed to record once it receives a sound spike in volume

And a hand held scanner that is tuned in to a specific frequency

the trifled meter will pick up any radio signal and will beep once there is one, I need this to then trigger the audio gate to open and let the sound come through from the radio scanner, once the sound comes through it will trigger the iPhone to record the audio samples

Should be quite simple for some who knows how to

I also have another project I need setting up once this one is done

2- Reversing polarity to change direction for forward and reverse
3- Motor synchronization via Hall Effect transistor pulse signals from each motor back to microprocessor
4- Current sense feedback monitoring (and adjustability) from L298 to ATMEGA 64
5- Reverse direction when current sense limit is reached (adjustable feature)
6- Safety shut off – when one motor stops the other receives command to stop
7- Adjustable run time
8- Event Logger &amp; reporting
9- EPROM memory to remember motor position when power failure
10- Communication to ATMEGA 64 via RS485 &amp; CAN Bus

C# Application For Embedded Systems Configuration (VCP)

>> NO COMPANIES – NO GENERIC BIDS – ONLY INDIVIDUAL DEVELOPERS PLEASE <<

CAUTION
If you are interested, please read CAREFULLY the information under "how to apply" at the end of this announcement. Incomplete bids will not get any answer!

For our current project we need a C# application that communicates with our embedded systems trough the (USB emulated) serial port. This C# application is used to do various types of configuration of the embedded nodes, the application will typically be used once only during the setup/installation stages of the embedded parts into the industrial environment. Since the program will mostly be used by non-technical skilled people, the application has to work very simple and reliable.

WHAT WE ALREADY HAVE
We have multiple of different embedded systems nodes already connected with each other. These nodes are communicate through CAN bus, typically around 80 nodes are connected on this bus.
Each of the nodes can be configured with different parameters.
For example, the switch buttons can be configured to have different colors, brightness, sensitivity and stuff like that.

THE START
Our CAN bus higher layer protocol is already defined well, you will get the bus protocol specification to retrieve/send data from the nodes. Since there is a high possibility that you aren

Schematic Keypad

Hey mates, i am currently looking for someone who can make me a custom made numerical keypad logger that can log datas
from a 7-pin data ribbon sensor. the datas have to be saved into an internal memory (small size) and time stamped. Nothing
should interfere with the original system key entry. it should time-stamp when bottom-right "ok" button is clicked and jump to
next line.If you are able to incorporate bluetooth into it so that the datas can be acessed remotely, that would be really good
also. Contact me for more info about that incury thanks.

Microcontroller UART/SPI

Hello, we have a very simple project to be done.
We are using an Atmega16 with a MCP41100.
Although the MCP41100 is based on SPI and the atmega16 supports SPI, the project itself is controlled via USB-UART

The project is done in embedded C. I have schematics even if its easy to visualize the problem.

We need someone who will be able to easily code and provide explanation.
This is only part of a project so we might need further help.

Motorised Blind Tilt Control

I am looking for a motorised controller which can alter the tilt of a venetian blind.

The device must be small, battery powered and operate using a daylight sensor.

The venetian blind has two cords which can alter the tilt. One cord rotates the louvers/slats in one direction until closed, the other cord rotates the louvers/slats in the other direction until closed. Pulling a cord in one direction has the opposite effect on the corresponding cord. Neither cord supports any weight. The middle/inflection point between the louvers/slate being closed in one or the other direction represents the
