Very very nice. Great idea. Full points for this one!
I don’t recommend taking Mr. Wake on an airplane though. Security folks might not like the looks of an alarm clock on a home made device with colored wires showing.
To turn of the alarm… cut the yellow wire … no no! they expected you would think that … cut the red one. Hurry!
Hahaha! Another great design. I somehow missed this one earlier, but then saw it on Hack-a-Day.
Yup, the range might be a little short - somebody might actually catch this one and shut it off! Have you thought of using a PIR sensor? Range on many PIR’s are about 5-6 meters (~20 feet). Soon as you stir out of bed, the robot would be scurrying! But again PIR’s are a bit expensive (about $5-$10 US) and they aren’t very directional. I would guess you would need at least three to tell what direction the victim sleepyhead is coming from. Something to think about though. Adafruit has a great tutorial on PIR sensors in case you want to try one.
Thanks for the laugh! An easy 5 stars! Awesome bot!
No, I did not think of PIRs, but will consider them now. I believe they are suitable for my purposes. Unfortunately I will not have time to work on it before challenge deadline, so it will be an upgrade project Thanks for the tip!
Similar to the PIR idea is a Similar to the PIR idea is a simple LDR or phototransistor. By sampling at 2 intervals with a short pause in between you can look for large changes that would signify movement. Plus it has the added benefit of costing next to nothing!
