|Write some software
||I need you to develop some software for me. I would like this software to be developed for Windows using PHP. I have a solar tracker, I am using RF315mhz transmitter and receiver for wireless transmission. But at the current moment the transmission is not happening. Thus I have connected the transmitter direct to laptop using USB. I need the data that is coming from the solar tracker that is disp...

|Custom Circuit Board for Sensors
||I need a circuit board designed to transmit data from these 2 or 3 sensors to either Teensy or Arduino so that the data can be read.
Nitric Oxide (NO) NO-A1
I am not sure if I will include the O2 one or not as there is another sensor already built with the transmitter circuit board. The sensors will be measure subtle amounts of these substances in the human b...

|Fast Barcode scanner
I would like to develop a fast 2D barcode scanner. One idea is to use a light carier of 38kHz , and filter the received light. So when a barcode pass under the transmitter/receiver (at constant speed), the output will show a series of pulses with different width. The output signal is a digital signal, i do the decoding myself. The barcode is black and white., the material is paper , the focus ...

|Write some Software
||Problem: Filtering sensor data in a warehouse to predict where an object is.
We are building software to identify where an item is based on the signal strengths of an array of non-uniform transmitters surrounding that object. Each transmitter broadcasts a Unique ID, a signal strength, tag and approximate geo-location. (see the JSON file below to see sample available information returned by transm...
