All projects

1. Minecraft server 2009 Ran a public Minecraft server with my dad, port-forwarded from the house. First taste of command syntax, server uptime, and most of the English I knew before school taught me the rest.
2. Coding class 2011 First school coding course at age nine. Visual programming in Scratch, which was a disappointment to my batch-script-trained nine-year-old self, but a useful lesson in how forgiving syntax lets the ideas come through.
3. First .exe 2014 First real Python program compiled to .exe. A rotating ASCII skull animation, age eleven.
4. Code teacher 2015 Six months as a kid-instructor for Lær Kidsa Koding's AKS programme, teaching Scratch to fourth-graders in Oslo public schools. The right age to learn that the word 'obvious' is doing a lot of work.
5. first 3D printer 2016 First kit 3D printer, age thirteen. Entry point into hardware: paper-thin bed levelling, host-side slicing, and the discovery that mechanical bugs throw filament at the wall.
6. First NN 2018 First deep self-learning neural net. Played the browser game Slope from extracted screen lines.
7. 3D printer v2 2018 Second kit printer, built with a friend. Bigger frame, beefier extruder, auto-bed-levelling, and dozens of benchies on the windowsill while I tuned each new filament in.
8. Hexaglow 2018 Co-founded a youth enterprise selling configurable glowing wall panels. I wrote the Unity/C# companion app.
9. LEGO plotter 2018 Python on a LEGO Mindstorms brick drove a two-axis drawing arm with a pen-lift. Mouse-controlled and surprisingly precise.
10. PLED 2018 Second youth enterprise. Custom LED lighting with a spectrum tuned to support circadian rhythm: warmer at night, cooler in the day, on a schedule the user could override.
11. Security research 2019 A year inside Windows internals, remote desktop, and auth systems. Formative.
12. Network deep-dive 2020 A year teaching myself how networks really work. Captive portals, DNS, traffic shaping, auth.
13. Color Polygraph 2020 A color polygraph trained on 20,000 survey clicks. Guessed age, gender, and mood from nothing but which swatches people picked.
14. Panasound intern 2021 First industry job. A summer internship at Panasound, a Norwegian audio startup. Go on the backend, Nuxt on the frontend, and the first time my code had to survive another engineer reading it.
15. Sound Flappy 2021 Flappy Bird controlled by your voice. Microphone loudness mapped to vertical velocity. A short game-jam piece from Torshus, unplayable on the bus.
16. Tactic blobs 2021 Game-jam mobile game inspired by the Russian variant of tic-tac-toe. Six blobs per player, bigger sizes overtake smaller ones. The board looks one way and is secretly another.
17. ASCII shader 2022 C++ game with a CUDA ASCII shader that picked the right glyph for each pixel patch.
18. Blink shooter 2022 Python shooter where webcam-detected blinks flip you between two color dimensions.
19. Minecraft 3D printer 2021 Converted any 3D model (including color and scans) into a generated set of Minecraft commands that build the model in-world.
20. Shape-shift miner 2022 Python mining-and-upgrading game where the OS window itself is part of the game. Buy the right upgrades and the window sprouts new rectangles at odd angles, turning the play space into a shape no game has any business being.
21. Cybersecurity lecture 2021 A community-week give-back: a lecture at a nearby high school on staying safe online, covering what data you leak, how it's collected, and how not to get caught out.
22. Drawing plotter 2022 A broken 3D printer became a pen plotter for one-continuous-line drawings. PC-controlled, slow, hypnotic.
23. AI content channels 2023 Automated pipeline scraping top Reddit content and publishing to YouTube, Instagram, TikTok.
24. Oda — Norwegian voice assistant 2023 From-scratch Norwegian voice assistant on a Pi Zero W. Custom RNN wake-word trained on 30k clips, Whisper STT, offline LLM, ESP32 sensor mesh.
25. Under-couch charging dock 2023 Four USB-C ports built into the living-room couch of a shared student flat. A 24V DC supply sized for full output on all four, in a Fusion 360-designed, 3D-printed housing with one on/off switch.
26. A song hidden in a frog 2023 A homemade compression algorithm that squeezed the full ASCII version of a certain song into the low bits of a single frog photo. A tiny decompressor reads the hidden bits straight out of the image and plays the result back as a live terminal animation.
27. Sine generator 2024 ESP32-controlled signal-level generator: analog gain stage, software-controlled DAC, potentiometer-set knob. ~26 dB gain, ~21 dB attenuation, single-line hot loop.
28. elektra.io 2024 Designed and built the Elektra student association site from scratch.
29. EV detector 2024 Detects if a car is electric. YOLOv8 for plate detection, custom CNN for plate reading, Statens vegvesen lookup.
30. Freq doubler 2024 Analog frequency doubler. Diode for the non-linearity, two cascaded LC band-passes with an op-amp buffer between them. SDR ≈ 21 dB at 2525 → 5050 Hz.
31. Teknisk Komité 2024 Founded and still lead the technical committee in Elektra, NTNU's electronics-student association. We maintain elektra.io and ship the internal tooling the rest of the association runs on.
32. Append Consulting 2024 Eighteen months at Append, a small AI consultancy in Oslo. Shipped four production ML projects for Norwegian public-sector and industrial clients. Most days, the model was the smallest part of the job.
33. Tesla-seat presence sensor → smart lights 2024 Wired the seat-occupancy sensor from a Tesla seat (repurposed as an office chair) to an ESP32. Sitting down turns the room red.
34. Tone remover 2024 An analog-electronics assignment asked for a band-stop circuit to remove a single tone from a recording. I solved it in software with spectrograms instead. The right kind of cheating, depending on who you ask.
35. Traffic light 2024 A road-grade traffic light retrofitted with a Raspberry Pi, a Flask web UI, and a sound-reactive mode. Bass goes red, treble goes green. The party mode ended up being the headline feature.
36. 4G RC car 2025 RC car streaming two camera feeds over 4G with a custom UDP hole-punching protocol for low-latency P2P video without static IPs.
37. Anti-alias filter 2025 6th-order Butterworth anti-alias filter for a 3 kHz ADC. Three cascaded Sallen-Key sections, with weird capacitance values built from parallel combinations of standard parts.
38. Analog buffer 2025 BC547 emitter-follower buffer between a 5.6 kΩ source and a 680 Ω load. Designed, biased, tuned with a potentiometer to hit the predicted 90% gain at 1 kHz.
39. FPGA dice 2025 Seven-LED dice on a Lattice ICE40 FPGA. Button-gated clock, 3-bit counter wrapping 1→6, LED logic derived from a truth table. First hands-on FPGA project, built in IceStudio.
40. Freq doubler v2 2025 Second pass at the analog frequency doubler. Same topology, much more careful. Measured inductors, hand-built capacitor values, Analog Discovery for the SDR estimate. SDR ≈ 26.7 dB at 3725 → 7450 Hz.
41. ML competition 2025 Designed and led an internal Kaggle-style ML competition between NTNU students and Hydro engineers. Wrote the brief, prepared the dataset, set the scoring metric, and learned that the metric is the whole project.
42. FPGA noise filter 2025 FPGA-generated white noise (LFSR) shaped by a Delyiannis-Friend active band-pass filter into a tonal output around 920 Hz. Digital pseudo-random source, analog band-limiter, audible result.
43. Omega clock 2025 A clock modded with LEDs and an ESP32, made as a host-gift for a student-association party. Day-long build.
44. Op-amp 2025 Operational amplifier built from discrete BC547/BC557 transistors: differential pair, current mirror, emitter-follower output. Characterised open-loop (A ≈ 400) and with ×10 negative feedback (A ≈ 9.7, THD < 0.3%).
45. Ligmax 2026 Custom boat platform with full sensor suite, dual cameras, buoy detection, custom hull, and integrated electronics.
46. Infinigrid 2026 Building AI that watches the electrical power grid and predicts its risks.
47. ViT + LoRA 2026 Adapting a pretrained vision transformer to a new task using LoRA, with low-rank adapters in the attention layers. Half make-it-work, half an excuse to actually understand why it works.
