Christian @ hackaday.io build his own USB Hub based on GL850G IC: I was looking to make a custom USB Hub for a project but I couldnt find any of them that worked and using the chip GL850G. The chip is pretty old and cheap, but in my case I didnt need to use any of the fast...

Imagine if a bit of data can be stored in a single atom or a small molecule, then massive volumes of data can be stored in a tiny amount of space. This theory was the topic of a research tries to develop a new method to store data magnetically in atoms. As the magnetization of an...

Monitor and log water quality (pH & ORP) and temperature from everywhere. Instead of performing regular checks with tester kits to maintain adequate pH and chloride levels in our (small) swimming pool, I decided to build a project that monitors the water continuously and...
