Project mention: Flipper Zero DarkWeb Firmware Bypasses Rolling Code Security | news.ycombinator.com | 2025-08-07Unfortunately that video is lots of talking and little substance, so it's hard to properly evaluate it. From the little info shown there it just looks like a nice repackaging of the old rolling flaws (https://github.com/jamisonderek/flipper-zero-tutorials/tree/...)

Project mention: Ember: A hot plate controller powered by USB-C Power Delivery | news.ycombinator.com | 2025-12-06
Hi, I’m Nathan, an aspiring engineer who likes to tinker with hardware. Earlier this year, I started making hardware/electronic projects through various Hack Club programs. It was perfect, but most, if not all, of my projects were being withheld due to high customs and import fees, so I wanted to change that.
Most of the price was actually assembling the PCB, and looking around the internet, I discovered the wonderful invention of the hotplate, and that I could make all of my PCBs myself for more than half the cost. Now, while I could have bought one on eBay, I decided to take up the challenge of making my own (because why not) and to make it as functionally portable as possible, so Ember was born.
I started reading how hotplates work and looked around the internet to see if anyone had made one, and I stumbled upon this repository (https://github.com/ikajdan/reflow-hot-plate). It was basically what I wanted to make, but reading through, I found that although it went up to 210 °C, the hotplate size was rather small. Also, it needed an external DC jack along with USB-C to be able to control/monitor it from a laptop.
