Detecting CVE-2021-31166 – HTTP vulnerability

By Ben Reardon, Corelight Security Researcher In this blog we aim to provide a little insight into part of the lifecycle of Corelight Lab’s response to a critical HTTP vulnerability. We’ve open-sourced many such responses over the last year (see Append… Continue reading Detecting CVE-2021-31166 – HTTP vulnerability

This Soap Dispenser Will Crush Your Germs

When it comes to cleaning your hands, [Arnov Sharma] is not messing around. He built an automatic soap dispenser using ultrasonic sensors, a stepper motor for activating the pump, and 3D printed components for housing a bottle of soap – a spectacular display of over-engineering. At least he won’t be …read more

Automatic Soap Dispenser Hides Arduino Board

If you’ve been hanging out here at Hackaday for awhile, you’ve certainly seen projects that were based around the concept of putting a miniature computer inside the carcass of some other piece of electronics. In fact at this point it’s something of a running joke, certainly we must have seen an Arduino or Raspberry Pi shoehorned into every type of consumer gadget ever built by this point. But if you thought this would be another example of that common trope by the headline, you might be in for something of a surprise.

Hacking A Solar Bubble Blaster With Grandkids

[Fmilburn] was having fun with his grandkids, playing around with a small Radio Shack solar panel, some supercapacitors and a Zener diode when the kids eventually moved on to blowing bubbles with their grandmother. To regain their interest he got an inexpensive battery powered, soap Bubble Blaster and converted it to run on the solar panel and supercapacitors instead.

His write-up is a pretty fun read, walking through his process, including an oscilloscope measurement showing how the capacitors’ voltage drops from 5.26 V to 3.5 V when the trigger is pressed, and interestingly, slowly recovers until it’s released a second …read more
