Thanks for the tip! I am considering all types of sensors, as I want this device to be compatible with as many as possible. Right now I am working on the RF communication part and a friend joined in with the LCD. After we're done with these rather softwarey tasks, we're going to switch to improving calibration for all analog sensors, including the water sensing. Unfortunately this is taking ages, as we both have day jobs. From your experience in this field, what would you consider a fair resolution for the water level sensing? cm? mm?Thank you for your input!

Glad to see that I'm not the only one using through hole components! Nice idea, I voted!

As someone who is in the process of making a PIC-based development board himself, I can see that there is a HUGE amount of work in your board..great job, friend!

that's how you waste 2 red leds :P

This device is "walking" at 0.12 km / h, while an average person will walk at 5 km / h without even putting in effort. Looking at the parameters of the motor, and the sutff you're loading it with, I say that a 0.1 A current consumption is a minimum, if we're optimistic. At 12 V that gives you 1.2W. Looking at the average efficiency of an adapter (90%), one can conclude that you're running your device with 1.35 W power consumption. Since April 2016 the price of 1 KWh in Oregon is 10.5 cents. If you take 8 hours as an average sleep, that gives you 0.84$ for the device only, not to mention that you have to charge your phone, and you're sleeping in noise. I don't know how many km's it takes to hatch an egg, but this device isn't doing it for free.

Looking at the average efficiency of an adapter (90%), one can conclude that you're running your device with 1.35 W power consumption. Now, let's see the phone: In average, it takes 2.5 hours to fully charge an iphone, at 5 V and 1 A, that is 2.5 times 5 W = 12.5 W. Calculating with the same efficiency of 90% at the charger, we get 13.88 W for a full charge. Let's say that you need to charge your phone every other day, so it's only 6.94 W per day, or 0.29 W per hour. Since April 201...

Since April 2016 the price of 1 KWh in Oregon is 10.5 cents, this results in 0.00164 KWh for your hatching device, this means 0.0172 cents for every hour you leave this setup hatching. I just searched to find that an average distance one has to walk to hatch a pokemon egg. Minimum is 2 km and maximum is 10 km if I read reliable sources. Let's just say 6 km is the average. That means that this device takes 50 hours to hatch the egg, 42 times the time it would take the average person to do that. It also results in a week of sleeping in the annoying hum, and 0.861 cents.Continuing with the theory: in Salem a bottle of beer costs in average 1.74$. In just 10116 hours you could have saved up enough money to buy a beer! Long story short: If you don't build this, but you DO play 8 hours of Pokemon GO every day, you get 1264 days of sleep in complete silence, you walk 50580 kilometers - which is good for your health, you hatch 5058 eggs of the 10-km-tough-guy-pokemon, and you even save up for a bottle of beer so you can celebrate! I believe that's worth it!

That's a great idea :) and a nice scope :)

Place 10000 of these all around the world, and give stats about the place one should visit when searching for a breath of fresh air. A bit l'art pour l'art, but hey :)

this project too has an emitter and a receiver, just saying :)
