Just a Regular OverEngineered FlowerPot
Arnov sharma Jul 13,2022
So Here's something Super Cool and unique, A Flower Pot made completely out of PCBs.I made this flowerpot by combining three different PCBs, I used a diamond-shaped board as a flower petal by soldering them together in star-shaped form.I used a previously made PCB as a leaf because its shape was somewhat similar to an actual leaf.As for the stem, I prepared a PCB that holds the flower and leaf together, this stem is then soldered on a base that holds the whole structure and also contai...

Detecting Unstable Electrical Grid with TinyML
AlexMiller112 Jun 26,2022
IntroductionElectricity is the heart of modern social and economic development. More and more countries strive to transfer to sustainable energy systems, which is quite a challenging process, as it causes increasingly unstable power generation and grid overloads. The unstable electrical grid can endanger people's lives and the safety of their property. This means that power systems should undergo timely monitoring and optimization, which AI and machine learning can easily handle.In fact, artific...
