DIY Low Cost Spectrometer: Being a final-year undergraduate student majoring in physics, I believe that labs and practical experiments are just as important as the theory when it comes to subjects like physics. Lab sessions and experiments provide tangible results which often…
Last year I started designing the spectrometer/spectrophotometer. It is not really too related with nanotechnology it could be used however ...
World's Cheapest Spectrophotometer
GPS Speedometer: My company car that I normally drive tends to have a "small" problems from time to time, the speedometer fall to 0 Km/h when driving (after some time it resumes again). Normally this is not a big issue since if you know how to drive a car, you are …
Make use of an ad hoc module by AMS in order to make a precious Arduino based tool. It will allow analysis of materials, including food and drink, through the spectrum obtained with a light stimulus and a sensor, and shown on the serial monitor. Spectrometry is an analysis technique that enables the identification […]

DIY Spectrometer) Explore the Unknown ->: Hey Guys! A Spectrometer is useful for detecting impurities in water and in other substances, or even just telling us what wavelength something is! If you have a mystery laser and you want to know the wavelength, you grab a laser with a known wavele…
Typical spectrometers use prisms or diffraction gratings to spread light over a viewing window or digital sensor as a function of frequency. While both prisms and gratings work very well, there are…
Hand Held Laser Spectrometer
Consulting project performed for AMI Purdue in the Winter of 2011. The task was to help them transition their miniaturized mass spectrometry prototype into a user-friendly, point-of-care device.

Cardboard Spectrometer, Rainbows in Your Pocket: Maybe you had noticed that different light sources give a wide variety of sights and sensations, especially due to colors revealed by illuminated objects. It can be true that some very nice pieces of furniture bought in a well lightened showcase, or…
A simple description of how a mass spectrometer works
With a few hours and about $60, you and build with essential piece of scientific equipment that analyzes light to determine what matter is made of.
How to Build Your Own Anemometer Using Reed Switches, Hall Effect Sensor and Some Scraps on Nodemcu. - Part 1 - Hardware: Introduction Since I started with the studies of Arduino and the Maker Culture I have liked to build useful devices using junk and scrap pieces such as bottle caps, pieces of PVC, drink cans, etc. I love to give a second life to any piece or any ma…
Note: This log entry is a living document. I'll be updating this post to reflect the current configuration as time goes on.. There will also be a log at the end of the post noting modifications to the log, etc.. UPDATED-----> 09.23.2014Ok.. It's been a lot of tweaking, and refining... A lot of going over the design, fixing issues and overcoming problems.. But I have reached a pretty good point with the spectrometer design.. I managed to design this part of the system so it can be used completely independently from the rest of the raman setup.. You can print this portion, install the optics, setup the fairly simple electronics, configure the software, make some minor adjustments to the optics so they're properly aligned, hook it up to a PC (or the ramanPi) and get some work done!This spectrometer should be about on par with what you'd get from an ocean optics commercial product... Well, at least as good as one could expect to get.. I might experiment a bit with better options than razor blades for the entrance slit.. But really, the
