Welcome
This is homepage of ham radio station oh5hba. Info about me and my station, which may interest other ham operators can be found thru menu. This page contains links that I use often in my everyday life. Reason for this site is just for own fun and it helps to find important things when i’m not at my own computer.

- For those missing limbs, a robotic prosthesis represents a real and useful way to regain capability. But such prostheses are traditionally very expensive and are inaccessible to a large percentage of the people who would benefit from them. In an effort to improve the situation, Pavel Kochetkov of Weird Motions Lab designed this affordable, open-source […]
- Appeals to nature notwithstanding, humans didn’t evolve to sit in desk chairs all day slouching in front of computers. Nor did we evolve to handle constant and near-unlimited access to delicious, calorie-dense foods. It isn’t surprising that so many people are at less than ideal health levels. But how can one work up the motivation […]
- There’s a handful of things we truly need in order to live, and food and water comfortably make the list. Unfortunately, our water and food sources are not always safe. Throughout the world — even in developed countries — pollution, climate change, and poor management are damaging our access to clean water and food. And […]
- April 22nd is Earth Day – a powerful reminder of our shared responsibility to preserve the planet for future generations. While the call for climate action grows louder, Arduino is committed to making sustainability an ongoing priority through concrete projects and global collaborations every day of the year. One of the most exciting steps in […]
- The joysticks found on ordinary controllers are quite simple, and as a result, they fail to provide much in the way of haptic feedback for the user. This is especially tough in racing or flight simulator games where making sharp turns should require a greater amount of force. YouTuber zeroshot’s project aimed to overcome this […]
