Book Safe (Secret Santa)
I made a book safe for my Secret Santa via Make in Belgium (Facebook group, also known from Koterij with Henk Rijckaert). It’s based on arduino. I did everything myself: programming, creating and printing case. I truly didn’t enjoy cutting in the book. It was a lot more work than anticipated.
Parts list:
- chinese arduino
- 2 buttons
- 1* 4-digit 7-segment display
- 1 relay board (to shut off after 30 seconds or so)
- one matrix keyboard
- 1 servo motor
- 2 rubber bands
- 1 book (sacrilege!)
