Project Description:

Hello, I need you to be be able to deliver 2 of these PCB boards to start. The PCB board will be small preferably no larger than 10mm wide x 20mm long x 2mm thick and will run off a [url removed, login to view] lithium rechargeable battery. So the components should be small. The battery on the board should last for a long time considering its mostly being used when there is key strokes. There should be no reason why it could not last for a week or even weeks on one full charge. The battery will charge automatically when the PCB board is plugged into the computer by the USB cable. The board will charge until the battery is full. The PCB board will have 16 push buttons connected to it. When you push any of the 16 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. There will be one LED lights on the board. The light will turn green when the board is turned on or plugged into the computer. When its charging on the computer the light will turn orange then back green again when fully charged. The buttons that are pressed connected to the PCB board will be saved every time the time stamp button has been pressed. When the time stamp button has been pressed the green LED light will flick on and off twice. This is to let you know the data has been saved. Whenever a button is pressed the LED light will flick once. The memory on the board will be 512K. When the memory is full it just stops recording and the LED light will turn orange. There will be 16 buttons altogether. 0,1,2,3,4,5,6,7,8,9,*,#,a,b,c,d, and b will be the time stamp button. When the time stamp button is pressed all key strokes are saved and then time stamped. Any new data pressed and time stamped will go to the next line in your saved file when downloaded. When you plug the pcb board into the computer there will be software you will need to open that you will make. When you open the software it will ask you to enter in a password. The software will be encrypted as well as the PCB board. You will enter in a password then you have access to the software. In the software you have the access to change your password. You also have the access to the current information saved on the PCB board or to download the information. If you download the information it will be saved as a “notepad” file.

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. I have a picture that I can send for the correct instructions on what will be done so there is no misunderstanding.
