Strengths and Weaknesses
Strengths:
- Hands-on problem solver: He creates physical solutions for design errors, such as soldering an “'on chip solution'” when he forgot I2C pullup resistors.
- Persistent learner: He admits to “'fighting the Rust type system'” until he succeeds, showing dedication to mastering complex new technologies like Embedded Rust.
- Analytical mindset: He performs comparative testing between components, such as “comparing an ESP32 with PCB antenna vs an external antenna” to verify performance claims.
- Cost-conscious engineer: He actively seeks value-driven tools and services, noting how “everyone has the opportunity to save $949 by learning how to do KiCAD”.
- Knowledge sharer: He documents his builds and lessons learned, like his “Saturday mini project” to improve antenna gain for the community.
Weaknesses:
- Hardware design oversights: He repeatedly misses basic requirements in his initial PCB versions, such as “forgot pullup pins on the i2c bus”.
- Datasheet misinterpretation: He spent significant time debugging because he “misread the pad mapping in the SAMD21 datasheet” regarding SERCOM pin functions.
- SPI protocol gaps: He lost hours to hardware debugging because he didn't realize “pullup resistors on the SS pins aren't optional” for shared buses.
- Incomplete research: He purchased a PRO subscription for a service only to find “no tyska bolag i screenern” (no German companies), suggesting a lack of pre-purchase verification.
- Low social activity: Despite his senior role and technical expertise, his follower count is low and his “Tweets are private”, limiting his professional networking reach.
Your Simpsons character
Lisa Simpson
Erik embodies the intellectual curiosity and technical proficiency of Lisa Simpson, specifically her passion for STEM and meticulous problem-solving. Like Lisa, he is a dedicated lifelong learner who spends his weekends on “Saturday mini projects” involving complex engineering tasks. He demonstrates a high level of academic rigor in his hobbies, such as when he “spent hours of hardware debugging” to master SPI bus configurations or when he “fought the Rust type system” until achieving a breakthrough. His focus on open-source tools like KiCAD and the Glasgow debug tool mirrors Lisa's principled and resourceful nature, always seeking to “save $949 by learning how to do KiCAD” rather than taking the easy path. Ultimately, his combination of being a “Senior Software Engineer” and a devoted parent reflects Lisa's evolution into a highly capable, principled adult.
Your MBTI personality Type
INTJ
Erik exhibits Introversion through his focus on solitary technical projects and his explicit bio statement that “Tweets are private”. His Intuition is shown by his focus on systems architecture and long-term goals, such as designing a sensor node to “run for 2yrs on a single CR2032 coin cell”. The Thinking trait is dominant in his logical approach to troubleshooting, such as when he “saved the time for HW debugging” by analyzing the Rust type system and datasheets. Finally, his Judging preference is clear from his structured, project-oriented mindset, evidenced by his systematic “Saturday mini project” approach to improving hardware performance.
Some pickup lines for you
- Are you a SAMD21 datasheet? Because I’ve been staring at you for hours and I think I finally found the right connection on pin function C.
- I promise I’m a high-gain dipole antenna, not a cheap AliExpress knockoff—stick with me and we'll see a 10dBm improvement in our chemistry.
- Are we on the same SPI bus? Because I’m definitely feeling a strong pull-up toward you, and I promise not to make it optional.
- I heard you’re a fan of 'on-chip solutions' for forgotten resistors—how about we skip the hardware debugging and go straight to the spark?
- Forget fighting the Rust type system; I’ve already realized you’re exactly my type, and no compiler error could ever make me give up on us.

Senior Dev at Big Tech. Ask me why Rust's type system is better than manual hardware debugging, or how I accidentally improved my antenna gain by 10dB with a brass tube.– @henrikssn
Your signature cocktail
The Rusty Pull-Up
This drink is built on a foundation of Swedish Akvavit, honoring Erik's roots and his query to “@svt, varför är inte dagens Agenda tillgängligt utomlands?”. The smoky notes capture the essence of a hardware hacker who “transitioned to SMD even for prototype boards”, while the bittersweet finish represents the time he “almost gave up (and moved back to C)” before finding his way in Rust. It’s served strong and precise, much like his “Saturday mini project” antenna builds. The copper wire garnish ensures you never forget your hardware fundamentals, as he learned when “pullup resistors on the SS pins aren't optional.”
Your Hogwarts House
Ravenclaw
Erik exemplifies Ravenclaw’s analytical spirit and insatiable curiosity through his meticulous hardware projects and dedication to the 'Embedded Rust' learning curve. His tweets reveal a deep love for learning and problem-solving, such as when he “spent a few hours of hardware debugging” to master SPI bus mechanics or “improved the antenna” for a sensor gateway just to gain 10dBm. He values precision and intellectual growth, noting how the “Rust type system” actually helped him catch hardware mapping errors. His resourcefulness in finding open-source alternatives like “Glasgow by @whitequark” rather than buying expensive proprietary tools further highlights a wit that prizes knowledge and efficiency above all else.
Your movie
Your song
The Scientist - Coldplay
Erik’s feed is a chronicle of meticulous experimentation, hardware debugging, and the pursuit of logic, much like a scientist returning to the drawing board. He describes the grueling but rewarding process of “fighting the Rust type system” and admits when he has to go “back to the start” after realizing a hardware error like missing pullup resistors. His hobbyist projects involve constant testing, such as when he “compared an ESP32 with PCB antenna vs an external antenna” only to be surprised by the results. The song’s theme of analyzing puzzles and working through complications perfectly mirrors his journey of “learning how to do KiCAD” and mastering embedded systems. Ultimately, his profile reflects a man who finds beauty in the data and the discipline of solving difficult technical problems.
