The problem with having a handgun for home defense is the danger of leaving a gun accessible to unauthorized users, but it needs to be accessible in order to be effective. The fingerprint gun safe solves problems that others like it don't. For example, it can mount directly to a bed frame or desk to prevent someone from stealing it entirely like others. It gives the user precious seconds of time that could be crucial in an emergency.
Design
This design would be simple and include an Arduino as a micro controller, a solenoid lock, a transistor, a fingerprint scanner, and an LED. The design was to use the transistor as a switch in order to trigger the solenoid lock to open when the fingerprint scanner is activated.
Cost Constraint
The budget for the project was a big obstacle. Only $40 was given in order to buy all the components. The shell and handgun were 3D printed using PLA on a Creality Ender 3.
