Guide & Review
Sandeep Patil, CTO at RedNerds
Model Name: FNIRSI-1014DAbstract :An oscilloscope that retails at INR 13K basically covers all of the hands-on subjects a 4-year engineering syllabus teaches in theory. The only issue is that none of this is practiced. We barely get past MCUs hands-on.This… |

This Clock Displays Time Using Air and Pneumatic RAM A unique experimental clock created by soiboi soft is gaining attention for its unusual way of telling time. While it may look like a fully air powered system, the design actually combines pneumatic logic with electronic control. Instead of relying only on circuits and chips, the clock uses air pressure to form its display, while electronics handle precise timing and control, making it a… |

This Nerf Gun Uses AI to Predict When You’ll Pull the Trigger A hobbyist maker has taken Nerf modding to the next level by integrating machine learning into a custom-built blaster called the Stinger. High-performance "flywheel" blasters usually suffer from a slight delay while the motors spin up to full speed, which can be the difference between a hit or a miss in a fast-paced game. To solve this, creator "stingernerf" bypassed traditional hardware… |
