I’ve been trying to interface with GPIB instruments but struggling a lot with GPIB adapters. Hopefully this can be useful to someone else trying to automate old instruments.
I started out with a Agilent 82357B USB → GPIB adapter. I was able to get my power meter to respond to a GPIB query once but never again. After fighting with
linux-gpib configuration on and off for a few months, I got fed up and got an Agilent E5810A Ethernet → GPIB adapter. Despite authentication issues on the university network, I had no problems communicating with my power meter no more than an hour after power everything on.
I’ve been wanting to make my own knives for a while now and decided it was time to just do it. Here’s what the finished product looks like.
For my freshman projects class in the Fall of 2016, we were prompted with using some aspect of touch tone phones in a new way. Ultimately, my group decided on making a cell phone targeted at the elderly population, some of whom struggle to use miniaturized cell phones or much more complicated smartphones.
The primary goal of our project was to create a working cell phone with as similar an interface to old landlines as possible to simplify use.»
The purpose of this project was to gain experience with a field programmable gate array (FPGA) and design of digital logic through the creation of a reaction timer. This timer must be able to wait a random length of time before measuring how long a person takes to react to an LED turning on. The purpose of this delay is to prevent someone from simply pressing a start and stop button in quick succession without ever having to truly react to an event outside of their control.»
