Fruitnanny is a code name for a DIY geek baby monitor. It uses RaspberryPi, a NoIR camera module, infrared lights, temperature and humidity sensors, and a custom Web UI. Chrome and Firefox with native WebRTC are used as clients. Right now it means all major platforms like Windows, Linux, Android, MacOS, and iOS soon are supported.
The main part of the project will be some 5 metre LED strip light laid around the bed. We’ll power these with an external 12 volt supply, switched using some MOSFET N transistors. The setup for this part will be identical to the dynamic lighting system I built before.
We present the design and prototype of an open source, optical fingerprint reader, called RaspiReader, using ubiquitous components. RaspiReader, a low-cost and easy to assemble reader, provides the fingerprint research community a seamless and simple method for gaining more control over the sensing component of fingerprint recognition systems.
In case you do not know what a rubber ducky is, it is a device created by Hak5. It looks and behaves like a flash drive, but it can be programmed execute keystrokes very quickly. It can be used to compromise a system in a matter of seconds. The only downsides are that you need physical access to the machine, and they cost $50, hence the purpose of this article.
We’re going to make use of a Raspberry Pi to build a network scanner to keep track of the hosts connecting to our local network. It’s actually pretty easy to do. And as we’re going to make use of ARP scans to do it, which are moderately stealthy unless you heavily hammer the network, it would be easy to make something that is pretty much invisible to most people.
The bonus in this project is that you'll be able to use the raspberry pi zero, the last one in the raspberry pi family with a small board, a very low consumption, equiped with bluetooth and wifi for all the wireless persons.
This project started about a year ago when I came across an old superhet valve radio on ebay. I didn´t had any useful application in mind when I bought it but as it was really cheap an in good condition I didn´t wasted that much thougths about it.
While I was waiting I came up with this idea to use the power of the sun to do the burning for you. It turned out to be actually quite simple if you can get your hands on the proper equipment, and I will show you how I did it.
Potatoes deserve to roam the earth, so [Marek Baczynski] created the first self-driving potato, ushering in a new era of potato rights. Potato batteries have been around forever. Anyone who’s played Portal 2 knows that with a copper and zinc electrode, you can get a bit of current out of a potato. Tubers have been powering clocks for decades in science classrooms around the world. It’s time for something — revolutionary.
