Richard Wendel III
I am a Computer Science major, EE minor at the University of Illinois.
After I started college I quickly realized that while I really enjoy CS, I also really like circuits.
What I like most is building the software and hardware interfaces to physical machines.
Ask me about Hyperloop. Huge fan of space
Software Engineering Intern,
June — August 2018
Developed algorithms for an image processing PCI card for a satellite.
Wrote C++ for an embedded PowerPC CPU running VxWorks to do image processing and tracking. Tested algorithms in MATLAB, porting to C++ and running unit tests to verify continuity
Tracking algorithms contained several parts, including an Assignment Algorithm. I greatly improved the Assignment Algorithm speed through binning, and implementing a multiple pass filter.
In order to predict and propagate tracks between image frames, motion model filters were used. I performed through testing and profiling of a Kalman filter on the embedded platform, helping to redesign the model to improve its speed.
Led electronics design, integration, and testing for two payloads for BIRST, an intern program launching payloads on ULA's Future Heavy sounding rocket.
Software Engineering Intern,
June — August 2017
Developing data collection, command and telemetry software as a part of a Flight Demonstration program.
Interfacing with a wide variety of COTS hardware. All of these pieces fit together in the data collection software — a multi-threaded C++ program running in a Linux environment.
Experience using COSMOS, an open source command and telemetry interface that Ball Aerospace developed, written in Ruby.

President and Electronics Lead,
September 2017 — Present
Illini Hyperloop is a student organization competing in the SpaceX Hyperloop Pod Competition. I have been involved with this project since October 2015, and have been the President since September 2017. As President I lead approximately 20 students, oversee the mechanical and electrical design, finances, and construction of our vehicles.
Competition 4 — TBA 2019
- The team is currently designing our fourth pod. This vehicle will use frictionless magnetic propulsion, and aim to be as light as possible in order to achieve high speeds.
- I am leading the propulsion system power electronics and battery design. In addition, I am guiding a redesign of the sensors and computing unit.
- The computing unit aims to be far simpler and smaller than the system used on the second pod. The BeagleBone Black is the only onboard computer, and our PCB will be a "cape" containing sensors and power regulation. I am developing the BeagleBone's Programable Real-time Units (PRUs) for high reliability sensor data.
Competition 3 — July 2018
- I became the President of Illini Hyperloop after the second competition.
- With SpaceX shifting the focus of the competition to speed, I led the R&D effort for our frictionless magnetic propulsion disks. I helped to create the testing apparatus for these disks, focusing on monitoring and logging the power electronics and force output of the disks.
- Reacting to the trouble we had with our friction brake system on our second pod, we decided to investigate magnetic eddy-current brakes. A 4 foot diameter, 1/2 inch thick circle of aluminum is spun up to several hundred RPM, and a magnet is lowered onto it. Using much of the same electronics to test the magnetic propulsion disks, I set up a monitoring and logging system to measure the magnet's stopping power.
- To power our propulsion system, I designed and constructed a high-power Li-Ion battery pack out of LG HG2 18650s, with a Elithion BMS. This pack was tested up to 80A discharge, and verified to work inside a vacuum chamber.
- Unfortunately, the team did not make it into the third competition. A rushed design, incomplete modeling, and unfinished CAD were our downfall.
Competition 2 — August 2017
- Having learned a lot from the first competition, I led the redesign for all of the electronic subsystems for our second pod.
- I designed the pod's overall electrical system, including batteries, sensors, PCB schematic, computing units, braking, and a detailed wire harness. I was away from campus during the summer build, and my team built the electrical system to great success.
- In addition to the pod's hardware, I led the software development of the embedded Atmel AVR boards, writing C. These boards were responsible for collecting data from all onboard sensors for the main flight computer, and controlling the brakes. I wrote an SPI driver for the flight software group to facilitate data transfer between the AVR boards and the main flight computer.
- Building off of legacy code from the first pod, I updated the LabVIEW base station.
- Computing consisted of a primary BeagleBone Black flight computer, which was fed sensor data by two Atmel AVR boards. Sensors, data lines, low and high power regulation were all integrated onto one PCB, with primary and secondary batteries supplying power. Our braking system had digital control from the flight computer using the primary battery, but could fall back to analog control using the secondary battery in the event of either a flight computer or primary battery failure.
- Overall, this second pod was much more of a success than our first pod. The computing and electrical systems worked well, but we needed more time to test and iron out some bugs. Unfortunately, mechanically our braking system failed.
Competition 1 — January 2017
- Soon after starting college I learned about the Hyperloop competition and the team on campus. The idea of Hyperloop was fresh and exciting, and it drove me to become even more involved.
- During my first year I began developing a LabVIEW base station, for pod command and telemetry. Because of this I eventually earned my CLAD certification (although it has expired now). I began tinkering with embedded Linux on the BeagleBone Black, and some simple sensors, like accelerometers, gyroscopes, and ADCs, since these were to be components in the pod's flight system.
- The first competition team was heavy with senior Mechanical Engineers and Aerospace majors, but lacked many Electrical and Computer Science majors. Most of the first competition team graduated, leaving an incomplete electrical system. By virtue of being one of the few people with some experience, in my second year I began taking on more and more responsibility for the pod's flight software, sensors, and some of the power electronics
- To summarize, our Pod was not ready mechanically or electrically, but the electronics were worse off. The first competition was a huge learning experience for me, I was exposed to LabVIEW, C++, embedded development, sensors, low and high power systems, and mechanical design.

Custom controlled Quadcopter
December 2015 — April 2017
Video of test flight!
Buying a quadcopter is just too easy. I wanted to build my own, so I did! During the winter break of my freshman year, I began to buy the parts and put together my quadcopter.
However, the quadcopter is not controlled from a traditional RC remote. I have a different set up. I created an Android app that acts as a controller which communicates via Wi-Fi to a Raspberry Pi onboard of the quadcopter, which then relays the inputs via a serial port to the MultiWii flight controller. I was initially inspired by an Instructable, so I decided to document my build process as well.
- Raspberry Pi server - GitHub
- Android remote controller - GitHub
- Multiwii Serial port communication implemented in C - GitHub
- Instructable tutorial detailing the entire build and setup process

Carnegie Mellon University
June 2014 — August 2014
NHSGA is a six week program that Carnegie Mellon University hosts. I was exposed to the artistic and technical side of the video game industry, creating video games with other programmers, artists, and game designers. I was able to work with two different teams as a lead programmer and create a total of three video games. I learned C# to be able to program the games using the Unity Game Engine. It was a great experience where I could focus all of my time and energy to develop great games.
