This project is a cheap rain sensor able to detect the occurrence of rain. The sensor automatically triggers a buzzer when a rain drop is detected and thus giving early indication of rain. The circuit is powered from AA batteries and it draws no current when in standby and consumes little power when the buzzer is on. It is easy to build and install.

Embedded temperature datalogger

Andrew Schamp has build a temperature datalogger to measure the temperature in his garden. He used a TC74 temperature sensor, 24AA1025 1024kbit EEPROM and a DS3231M+ real-time clock to record the time and temperature hourly onto the EEPROM. He also implemented a serial interface for reading the data at the end of the sampling period. The device is based on Arduino-compatible Boarduino. Every hour, the device takes a sample, and then goes to an extended sleep state, to be awoken an hour later by the interrupt from the RTC. [via]

Arduino And Flash Tutorials. All Of A Sudden.
Written by d.gomba@arduino.cc

If you (like me) get to know the term “software tutorial” related to some professional products like the Adobe Suite, you are going to be quite amazed in seeing Kevin Hoyt introducing Arduino as the Physical counterpart of that high-level, client-friendly, closed-source, wonderful software which is Adobe Flash.

[...] If you like me spend a lot of time -everyday- in front of the computer, and that’s just great..don’t get me wrong…Adobe Developers built some of the collest apps out there…but…what happens when you close your laptop and walk away? For most part web developer just live there in the Ether, you’ve got nothing really to show from your hard day of work…but, that bothers me, so I want to kind of escape the bounds of the computer, and do something more…[...]

This is kind of a deep witnessing. You to judge what that really means.

Anyway, here come the tutorials I suddenly found over the internet (thanks David!). Note that none of them goes over the 150 views, even if they are totally perfect. I hope this post helps to spread the message. Here‘s the playlist of all (9) videos. I embedded three of them here.

This project shows how to build a cold coffee (frappe) Machine using plain build materials. On the pages below “Giorgos Lazaridis” describes the procedure of building the coffee/sugar tanks, the raising/lowering mechanism that will blend the coffee and the rotaing glass table. He has to overcome many challenges to achieve his goal and he describes all them in his website.
