Tilt-based led light

Hello makers, readers and curious!

   I´m here today to bring you a sort of toy I have made for the Arduino Day (March 28th, 2015). It is a simple tilt-based LED light (images below), and despite the fact that it features no Arduino (!?), it made me proud of my maker capabilities!. 

   The working principle is simple: depending on the  position of the tilt ball switch, the LED lights or not; you can check the schematic below. I have used the following materials:

- 2x 1.5V coin cell batteries

- 1x 100R/ 0,125W resistor

- 1x Tilt ball switch 

- 1x 5mm red LED

- Soldering

- Glue, to put the batteries together :) 

The original idea came from my mom, which is a special children's teacher, and it intends to stimulate and entertain them, and help them learn quickly.

I have not tested the toy with children so far, but will be glad to share the results with you when I do. See you guys next time!.

The Hackaday Prize 2015 !

Hello readers, how are you doing today?

   So I´m back to this blog after some time, now to spread the word about an incredible opportunity form the Hackaday website team: today is the beginning of a new Hackaday prize, the @HackadayPrize 2015!. This is a maker competition in which you can submit your idea to change the world (or just to water your plants more efficiently..), and for which there is a go-to-space first prize.

   I have entered a project in the 2014 edition, having reached the quarter-finals with mine `chip timing for running clubs´, you can see my project in here. For this year´s prize, I am planning to enter this open source weather station here, which features a bunch of sensors and communications options, all of that being supplied by a fraction-of-watt solar panel!.
   By the way, the 2014 champion was a project called satNOGS, satellite tracking stations. So if you guys have any project idea and would like to share it (and maybe win a trip to space and many other perks), enter the Hackaday prize now!. See you guys soon.
