GPIB Issues

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.


Making My First Knife

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.

Hohm Phone: Cell Phone for the Elderly

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.


FPGA Reaction Timer

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.
