This box reads any card with a magnet strip and, if you’re on the registered personnel list, turn on the shop power via a relay. A sole person, to be added to the program file upon creation, has the power to add others to this list for the utmost security. Step 1: Hardware This is …
Last month we brought you word of tonyhax, a clever exploit for the original Sony PlayStation that leveraged a buffer overflow in several of the games from the Tony Hawk Pro Skater series to load arbitrary code from a specially prepared memory card. But now [Bradlin] has taken that idea a step further and developed a software exploit …
A China-based manufacturer called RAK Wireless has released the RAK833 LoRaWAN gateway module a couple months back. This has already been used hugely to create a gateway for ‘The Things Network’. Now they’re back with the new RAK8213, an NB-IoT and LTE Cat M1 module in the same mini-PCIe form factor as the RAK833. The RAK mini-PCIe card is constructed …

Story The quality of the air that we breathe, is very important to our health. This device analyses the air quality inside our homes, and records the values in a SD card. By analyzing the stored values, we know how the evolution of the parameters thru time was. I will use temperature, humidity and air …
Introduction A data logger is an electronic device or instrument that records data over a period of time. It allows the user to record time or location stamped data which can be viewed at a later time or real time. Irrespective of the type of data being logged or the kind of data logger, these devices usually …
Introduction Often times, we have the need for a way to store data in our projects, and most of the time, the EEPROM which comes readily to mind has a limited storage capacity, and issues with the format and nature of data it can hold. All this and more makes it probably not the best …

MV is the ability of a computer to see using analog to digital conversion and digital signal processing. The key characteristics that make a machine vision module better are sensitivity and resolution. These systems allow machines to see a broader spectrum of wavelengths such as x-rays, infrared or UV light. Nowadays, it is mainly used …
In this post we will make a cool Christmas greeting card with the possibility of changing the music and much more, with Cayenne IoT. Things used in this project Hardware components Arduino MKR1000 × 1 LED (generic) × 1 Buzzer × 1 Jumper wires (generic) × 1 Christmas Greeting Card × 1 Software apps and …
Firmware is a type of software that provides control, monitoring and data manipulation of engineered products and systems. A USB device firmware hack called BadUSB was presented at Black Hat USA 2014 conference, demonstrating how a USB flash drive microcontroller can be reprogrammed to spoof various other device types in order to take control of …
