Introduction
My projects this year were to create a new user interface for the high voltage source and to redesign the LED monitoring system.redesign a Led circuit that would contain many LEDs, activate them by address, then holds the flashing addressed Led in memory and activates another Led to blink, allowing the circuit to have multiple flashing LEDs, in the final circuit there will be around a thousand LEDs. This massive circuit board will be for a calorimeter, that will be use to run experiments on about a thousand crystal samples of lead tungsten at the Jefferson Lab. This circuit would be used to check if the PMT are functioning properly during the whole experiment. My main project was to code a new user interface for our high voltage source. This new interface will be able to turn each channel on/off and adjust their current and voltage. The old interface was not user friendly and was hard to learn and use. This new interface will be designed to be user friendly and intuitive.
LED Ideas
Previous design - At the completion of our project last year we had produced a circuit that addresses LEDs, remembers that LED being addressed, then you can readdressed that LED, so that we can access each LED individually and control the frequency of they’re blinks. This is all done through our controller an Arduino Uno, Which we programmed to perform the required functions. Our prototype did not scale up very well. This is because their were too many components that took up too much space on the circuit board. To fix this we need to look at a circuit with less components and more software manipulation.
Bit-Line/Word-line - My professor suggested looking into Bit-line/Word-line architecture. Using an ardinuo or other like device, we can send signals down each line. This will activate the transistors on each line. The spot where the lines intersect is where the LED will be. This will only be active when both type of lines transistors are on.
