Atmel 1284PU Microcontoller Powering a 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… Continue reading Atmel 1284PU Microcontoller Powering a CCD Circuit Driver

Mega 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… Continue reading Mega 2560 Stepper Motor Controller Sec II

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… Continue reading Stepper Motor Control With LM350 Voltage Regulator

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… Continue reading Fluorescence of Biological Dyes Section ll
