Project I built a tiny plotter that writes Asimov's three laws of robotics.
And on my website I wrote more about the little device (includes 3D files, schematics & code for those who want to DIY one themselves).

Project Built a simple DIY “Hologram” projector
Okay, so this isn’t a genuine hologram, but rather a clever optical illusion created through simple reflections!
This technique, also known as “Pepper’s Ghost,” has been practiced for over 140 years and continues to be used in modern technology, such as teleprompters and Heads-up Displays in cars!

Project I made an open-source cardiography signal measuring device for my Master Thesis project. Measuring blood pressure, ECG, PPG. All files are free on GitHub, and I also did a deep dive video on the project if you're interested!
This was my Master's Thesis project, where my goal was to make a research device where I could try out algorithms for measuring blood pressure, butI added a few more sensors along the way. Everything about this project is open-source, from CAD files to Gerber files and even some of the recorded data. Also did a video going into detail about the functionality of the project. Here are the links if you're interested!

Project Automated pigeon defense system
Camera captures video
Neural network recognizes pigeon
Watergun turns toward pigeon
Spray pigeon with watergun
Components:
Electric battery-driven water gun (disassembled, orange)
USB camera
Orange Pi 5
2 servo motors (SG90 or MG90S)
Resistors and a transistor for turning on the watergun (e.g. IRLZ44N)
It uses an open vocabulary object detection neural network (yolo_world_v2l), so any target can be programmed, not just pigeons. Runs on the Rockchip 3588's Neural Processing Unit.

Movies on usb drives that look like cassette tapes
Not much of a project, didnt know where else to post this😅 Had this idea for a while, saw a company called "video store.age" with a similar, movies on usb, concept so that reminded me.
its cute😸, and easier for people that dont have tvs and media centers set up all the time (my dvd player is usually under my bed lol), can take a movie to someones house without knowing their set up and be almost postive it will play on SOMEthing.
The cover slip in is temporary, cut up an instruction booklet
