DIY SERVO triggered DOOR LOCK WITH CAPACITIVE TOUCH KEYPAD
since he was a youngster [Giorgos Lazaridis] has always liked the concept of having an electronic door locking mechanism, as well as now that he has the means, he’s decided to build one for protecting the door to his apartment. He phone calls the job “simple as well as cheap”, though we’re not sure about the very first part. Taking a look at his extremely detailed develop log, you can see that he has invested rather a bit of time as well as effort into this impressive project.
Buying an off the shelf product was costly as well as not a whole great deal of fun, so [Giorgos] disassembled his door’s locking system to see exactly how he may be able to actuate the lock digitally himself. With very little adjustments to the lock, he was able to add a servo which reliably opens the it when triggered.
With the mechanical part of the job out of the way, he spent a excellent offer of time working on the door’s electronic components, including the PIC-based controller as well as capacitive keypad. The keypad proved to be a bit of a problem, however after a few revisions he discovered a style that was both trustworthy as well as pleasing to the eye.
The locking system works quite well, as you can see in the video below, as well as [Giorgos] is rather delighted with the results.
