We Tested JBD, Daly & JK BMS After the E-Rickshaw Hack — The Vulnerability Is in the Hardware We recently came across reports covered by news outlets about electric vehicles, specifically e-rickshaws, being remotely hacked and stalled in the middle of busy roads. The attackers were using Android apps, some of which were available on the Google Play Store under names like BAT-BMS, Epoch Li-on and Overkill Solar. These apps were apparently able to connect to some specific brands of the… |

Build an ESP32 Voice Controlled Drone with LiteWing using Python Drones are amazing little machines, but most of the time they are controlled using remotes filled with buttons and joysticks. While experimenting with our LiteWing drone, we started wondering, wouldn’t it be cool if the drone could simply listen to what we say? That idea eventually turned into this project. We built a voice controlled drone using ESP32 for the… |
