The scientific method requires making observations, recording data, and analyzing data in a form that can be duplicated by other scientists. In addition, the scientific method uses inductive reasoning and deductive reasoning to try to produce useful and reliable models of nature and natural phenomena.
Well, this may be the ugliest test platform I have ever made but it sure worked, I had to modify my circuit board @ R8 going to pin#3 at the opamp [LM324], by running a bypass from the C9 [200pf cap,] to pin#3 @ the LM324, some strange ground problem I can't quite figure out yet from manually placing the components on the PCB design circuit in DesignSpark.
This is my second installment on using PLX-DAQ as an easy method of sending data from an Arduino or any AVR related MCU to Excel. Here I will be showing you how to process the data into a graphical chart for plotting it's values...the easy way 🙂
These are the capabilities of this technology, and with the advent of 3d printing and 21st century design software, projects such as mine and others like it, will continue to provide fresh innovations for the market place, and a vehicle for the citizen scientist to deliver technological modernization to under developed regions in desperate need of it.

The Mega 2560 was chosen because it is a low cost and efficient MCU with sufficient PWM and digital int pins that fit well with the design of this project. Second, I could not drive the CCD and MTR control all with the Atmega 1284.
This is another example I wanted to share of cost effective measures I have integrated into my overall project designs (most of the time because of budget constraints,) but I have been able to produce many high end parts that would otherwise cost many hundreds of dollars had I bought them outright.
a downloadable Power point presentation, I am presenting an amended version here to illustrate the main points and history of this long running project.
This is the control console for the DAV5 V3.01 Raman spectrometer, I designed it on FreeCad v0.16. I will be having this 3d printed by Sculpteo using POM material (powdered nylon type material,) color [white] for about $107.00US, as always, all my 3d parts are manufactured by Sculpteo and I have over 236 designs uploaded … Continue reading KeyPad & LCD Display Control Console
This is the 2nd installment for the V3.01 Turret Grating Controller project for the 3D printable Raman spectrometer project. Below is a link to the video @ my YouTube channel demonstrating the newest functionality and code changes. UniPolar Stepper Motor Controller Optimized I updated the code significantly, I added " lcd.setCursor(12, 2); lcd.print(i--);" to … Continue reading UniPolar Stepper Motor/ULN2003 Controller Optimized
