Rendered Concept Images Blender 2.79 (Luxrender/Photoshop)

"The Anvil" my rendition of an old but very useful tool...
These R 2 more components in my Raman spectrometer but I decided to get a little "artsy" with it. On the left is, a Holographic diffraction grating 25 x 25 x 6mm mounted on my design (the color's are an actual spectrum from a chemical dye called "Rhodamine b,") imaged from my spectrometer.

On the right is a silver reflective mirror, 50 x 50 x 3.5mm mounted on my design also.

The sound of 1 bolt clapping...

"2 Donuts & Coffee" this is my 1st full scene render in Blender 2.79, thanks to the tutorial video series from Andrew P Price@andrewpprice the blender guru:

It took me about 4 days to complete the video tutorial but it was worth it, it taught me so much more in depth working knowledge about Blender I never would have realized without it, anyway's this is my interpretation of "Coffee & Donuts" for breakfast.

The two images below were rendered in Photoshop

Interstellar Black Hole

These are images processed using Blender 2.79 and rendered using Luxrender 1.6.0

I just thought this Japanese lamp model was very beautiful and decided to do my own rendered interpretation of it.

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
PLX-DAQ Data Transfer To Excel Using An Atmega1284 MCU

I have Excel 2016 and Windows 10, two powerful platforms in my humble opinion, well thanks to an individual named Net^Devil over at the Arduino forums, he has a very clever program that I think perhaps has in large part solved a problem for me.

Nice profile pic. :) I really need to finish up the #Interdimensional Portal Gun project up, but it sat in a car too long and melted so I'm starting from scratch again now. Someday...

You've some interesting work 'round here. Chemistry is a bit beyond me, so I'll be mostly watching/learning!

Doing "good" in the world, doesn't always mean, doing something "phenomenal" or "unprecedented," it often just means, to be "Magnanimous."

Sometimes, it is within the simplicity of a thing, that the much finer genius can be found...

The way of the Spectroscopy Ninja: seven basic principles.

A Spectroscopy Ninja will...
never stop practicing
use all resources available
know no "fail", just imperfection
not "Undo" what has been done
instead do it again and do it right
always see room for improvement
not loose patience, as progress will come

Because from learning comes knowledge

from knowledge comes understanding and

from understanding will come great wisdom.

Are you sure? yes | no
