I’m breaking a little protocol today and talking about my research over the past two years. I started this venture around the beginning of January of 2015, sounds benign enough but actually I had a very close friend, who had recently lost a relative to which they thought was under suspicious circumstances.
A situation that for all intents and purposes, might rise to a dime store mystery novel. (no joke!) if I was inclined with the skill to write such things, I probably really would, anyway, without getting into the personal particulars of it all, there was a “white powdery” substance in a bottle that should not have been in there…yeah, getting it now? This friend asked me if there was anyway to find out what it was and I said yeah you can take it and get it analyzed, it’ll cost some money but it can be done.
For whatever reason…

well having a stroke several years earlier didn’t do me any favors. So, I developed a system of log books and these logs corresponded to files saved on my computer as a backup. I had to literally annotate just about every little thing I was doing, I have a short-term memory problem, but if I have a log of my previous actions I can recall it well.
Now this is the full spectral range from 0 - 1323 pixels, you will notice at the far left of the chart a line shooting straight up, this is the transmission line, which use to be the "absorption" line, by implementing this equation: (10ᶺ(-B2))*100 We can "flip" the spectral image right side up.
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
