1 X 4 KeyPad Matrix & LCD Display Control Console

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 […]

UniPolar Stepper Motor/ULN2003 Controller Optimized

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 the […]

Microstepping The 28YBJ-48 Stepper Motor

Advantages of multi-grating turrets in spectrometers Phase I There are significant advantages of multi-grating turrets in spectrometers. Quite often it becomes necessary to select two or three gratings to achieve efficient light throughput over a broad spectral region. Turrets make grating changes an easy push-button or computer controlled operation, and also reduce the risk of […]

Windows 10 – Arduino Data Transfer to Excel 2016 PLX-DAQ Protocol

    UPDATE 5/30/2017 10:06:AM I have just tested this program on my Atmega 1284P Development board and it works perfectly and the Arduino Mega 2560 🙂 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 […]

Communication between Arduino and Excel in Windows 10

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. I needed an alternative way of importing my CCD data directly […]

CCD Fast 8 Bit Driver Circuit

REV B           Update: 5/27/2017 I had to put the 16 bit driver circuit on hold for right now, there is an over heating problem with the ADC that I cannot solve right now, I have 2 boards made up and both have the same issue. So I have decided to […]

Atmega 2560 Stepper Motor Controller Sec II

Well I finally got the code worked out correctly and the switches work now. I placed a 0.1uf capacitor at each switch with a 10k resistor to ground for switch debouncing and fixed it in the code also. The LCD displays the motors direction now when the switches are pressed, now the hard part…either hack […]

Stepper Motor Control With LM350 Voltage Regulator

I’ve been working on this concept for awhile on the side for this project, it’s incorporated directly into the Czerny-Turner configuration. Most of the prototype is on a 590 pin breadboard with an LCD screen (1602-C) to display data output., motor control (using a 28BYJ-48 Stepper motor) Here is the concept below with an explanation for […]

Atmega 1284P Powering a 16 Bit CCD Circuit Driver

This is a project that I have been working on for almost a year on Hackaday.com, it is the CCD detector portion of the 3D printable Raman spectrometer project of mine and I finally got someone far smarter than me to help me out on the AVR part of all this and I guess I […]

Fluorescence of Biological Dyes Section ll

3 Biological Dyes in Water, Ethanol and Methanol Author, David H. Haffner Sr. 8/29/2016 Abstract In most polar solutions, such as water and alcohol solutions, ions diffuse more rapidly than covalently bonded molecules, because most ions are smaller than most molecules, and because of their greater polarity caused by a negative or positive charge, ions […]
