Hello. I have an experience in multiplexing of up to 250 analog inputs for AVR microprocessor. I have some question for your project. Can you specify: - a range of voltage of your signals, min/max, volts - required precision of the measurements, % -a frequency of incoming signals , Hz (or speed of changes, i.e., the frequency of measurements)? I can make a "frontend" for display of the values (for PC or MAC) on computer's screen in convenient (and aestetic) form. Also, I can make a design of hardware multiplexor for those signals. I will make a prototype for debug purposes, so will be able to demonstrate a device. If you need to obtain that prototype by mail- the price for a components and delivery will be added to the work cost. My current price includes the schematic, PCB-design and code for controller, but is not final until we discuss the questions I wrote above. With best regards Maxim Bulkowsky

Hi. Interesting project. I congratulate you on your initiative. For proper selection of hardware (microcontroller, sensor, displays) I need to know the type of variable you want to monitor (temperature, level, pressure, etc.). I can choose any microprocessor with analog inputs sufficient for the number of variables to be measured. What level of quality do you want in the displays ? (color, size) and how is the presentation of different levels ? (bars, circles, percentages, etc). I have a project that measures six variables of temperature and are presented on a monochrome LCD screen as bars. This works fine !!!. I'm sure you serve in your project. If you want to know more details please contact me. regards Pardo Darwin
