Snoozelock – the multistep alarm clock #ShowAndTell #Adafruit @Adafruit

From the May 15th edition of Adafruit Show and Tell, Lucian demonstrates his awesome project: Snoozelock

This is a three part wireless alarm clock that functions kind of like an airlock. You attach one part to your ceiling, one to your door, and one somewhere outside your bedroom like your bathroom door. The alarm goes off on the ceiling node, and to turn it off, you have to go out the door, close the door, and then activate the bathroom node. Go back and open your bedroom door again, and it turns back on. And it stays like this for 10 minutes. There’s absolutely no optionality to it. Once it goes off, you’re up. Good morning!

It’s built on mbed/bluepill, NRF24l01 wireless, Adafruit’s DS3231 RTC, SSD1306, 5V buzzers, and AA batteries. It works for about 8-10 months before needing the batteries replaced. Lucian is still working on the case, saying it’ll need screw on covers to make sure it takes as long to disassemble as it does to time out normally.

So yeah. Snoozelock. A horrible device for lazy people. You’re welcome, sleepy me.

See the appearance on the Adafruit Show and Tell episode below. And of you want to show your own project, here is how to join the fun every Wednesday at 7:30 PM Eastern.




Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
