My name is Robert Alexander Von Hoene. Everybody calls me Alex.
Welcome to my personal web site.
Pronouncing My Last Name
The first word is the German "Von".
(Not the Dutch "Van".)
The second word is pronounced like the English word "hone".
I studied computer science at Indiana University
in Bloomington, Indiana from 2013 to 2017.
I am currently writing software to optically track the flow of blood cells in mouse livers
for the Biocomplexity Institute at Indiana University.
From Summer 2014 through Spring 2016 I was an undergraduate researcher at CREST.
I worked on custom electronics for GPU-bearing multiprocessor quadcopters.
I also mentored high schoolers in developming real-time software (in C), CAD (SolidWorks and SolveSpace), and rapid prototyping.
I have also done a little bit of freelance electronics development.
I am a two-term board member of Bloomington's hackerspace, Bloominglabs.
Come and visit on Wednesday evenings to work on your projects and meet interesting people.
Our motto is descriptive: A space for sharing tools and knowledge to make stuff!
Here are some of my projects
and also my wiki contributions.
I built a RepRap Prusa 3D printer while I was in high school.
2013 through 2014, I was active in IU's defunct 3D printing club "Bfabs" (Bloomington Fabrication Group).
Here is the old blog,
My interest in 3D printing and activity at BFabs lead directly to my job at CREST.
As activity at BFabs wound down, I became active at the nearby hackerspace.
I have a technician-class amateur radio license.
My callsign is KD9CKV.
In 2013, I earned the rank of Eagle Scout
from troop 555 in Columbus, Indiana.
Please enjoy a look at my troop's excellent image archive.
