The more I get to play with hardware, the more I get to see how security is lacking or implemented poorly (and I’m being very polite here). This time, I would like to share my 315mhz/434mhz RF Sniffer project, which can be used to open poorly protected gates, cars, etc. Nothing new under the sun, […]Read More RF Sniffer – open gates, cars, and RF remote controlled devices with ease.
Here is my circuit design for Arduino keypad, using only 1 analog pin (instead of 7 serial pins), 6 resistors (can be reduced to 5) and 1 capacitor: And now for the full story: I decided it’s time to add a keypad to my Arduino playground. Usually, those simple keypads come with 7 pins (actually 9, […]Read More Arduino keypad with 1 Analog pin
So, I bought myself this Robotic Arm Kit (similar to this) from China, since I thought it will be a nice thing to play with. Unfortunately, I didn’t notice the ‘Kit’ part in the name, and surely enough, the parts arrived disassembled. Alas – they also arrived without any documentation. After some googling, I found […]Read More My Robotics Adventures.
