Short Bio:

My name is Nathan Zimmerman and I’m an electrical engineer that enjoys doing and learning nerdy things. By 4th grade, I decided I wanted to be an electrical engineer and by the grace of God I am one now. When I was younger, I greatly enjoyed creating and making projects with legos and such. While one is never too old for legos, I now have the opportunity to work with much more interesting building blocks such as microprocessors, FGPAs, traveling electromagnetic waves, and mathematics! My dream is to continue to learn more about the amazing world around us and to apply that knowledge in helpful ways.

I’ve had the privilege of working on electronics with some great companies like John Deere and Appareo Systems. Learning about electronics, mathematics, and physics is my favorite hobby/past time. Have fun looking around my humble and probably outdated website and feel free to contact me if you have any questions!

Skill Sets:

The following is my informal list of skills that i’ve found fun to keep track of over the years.

Hardware Design:
One of my favorite applied EE skill is embedded electronic design. From problem formulation, to designing hardware, to manufacturing setup, and finally to maintainability. The following are my electronic design skills:

• Schematics/PCB Design Tool Experience: Altium, Xpedition, Pads
• Circuit Design Experience: Precision analog, SMPS & LDO supplies, high current drivers, motor drives, transient/ESD protection, radio transceivers, wave guides, antennas
• Circuit Test Experience: EMC compatibility, vibration, physical shock, ESD, load dump/transients.

Embedded Low Level / High Level Software Design:

Without software, one has a brick. Application of high/low level software allows one to create neat and powerful applications.

Experience: *Low , **Medium , ***High

• Languages: C ***,C++ *,C# *, Assembly *, Javascript / NodeJS ***, Python **, Java *, Matlab **, Lua **
• Web Tech: HTML , CSS, Javascript , Jquery , PHP , React, Vue, Nginx
• Cloud: Azure **, AWS *, Docker *
• Database: Kusto ** , Influxdb **, Graphite *, SQL *, MongoDb *
• Embedded OS: Free RTOS, TIRTOS, ThreadX, OpenWRT / flavors of Linux
• Embedded MCU Experience: MK22FN128VLH10, MKL25Z128VLH4, AM3352Z, STM32F051, STM32F303, LPC1768, LPC1347, MSP430G2553, MSP430F5529, CC430F5137, CC1352P, ATMEGA162, PIC18F4620, ESP8266, ESP32, ATSAM4SD32CA, FC9000

Math:
Math can help solve problems and quantify quality and risk. More importantly, its a lot of fun! See some of my math notes here. To solve various problems, I find the following algorithms and concepts helpful:

• Estimation: RLS, KF, EKF, UKF
• Optimization: LSQ, NLSQ, Constraint handling
• Control: MPC, PID
• SysID: Discrete TF, N4SID, Gray Est.
