Patrick explains a little more about his latest Arduino hardware project. Thank you for having a gander at my 19th Kickstarter Campaign! Let me introduce you to the “Tommy-Knocker”!

This kit uses a CD-ROM drive and an Arduino board to build a clever robotic lock. This dude used a bolt to create the project and it's voice activated.

[Andrea] just sent us this great student hack he made for his room. He’s constructed an Arduino keypad door lock — without using any proper fastening hardware! The entire buil ...

The security flaws on this common hotel keycard lock are nothing short of face-palmingly stupid. Look closely at the picture above. This is a hotel room door swinging open. The device he holds in h… ...

Which is a long-winded way of saying check out this Arduino-based project which shows you how to build – in miniature – your own IoT smart door lock prototype system using a Nano ESP32 and the Arduino ...

Perhaps you could create an Arduino device to lean on the door right before the Arduino device bolts the door. It's not clear if the lock unlocks the door when you close that incognito browser.

He has fashioned an Arduino-powered door bolt that locks itself whenever you open an incognito browser window. Always nice when a computer gives you a helping hand.

Once downloaded, upload the script to your Arduino Uno using the Arduino IDE. After uploading the script, test the system by entering incognito mode on your web browser.

If you need a reminder not to put your complete trust in standard combination locks, here it is. Samy Kamkar, who once also engineered software that can hijack drones, created a motorized lock ...
