(This instructable is dedicated to my fellow brother Rodrigo, who starts a new life today; and to all the people who thinks Valentine's Day - and its Colombian equivalent: Love and Friendship Day in september- is the worst nightmare in the year)
Valentine's Day: flowers, chocolates, cards, love is everywhere. All the couples kissing and hugging and saying tiny lovely silly things. Edward and Bella Forever And Ever!
Well, I think I'm a very romantic guy. But, unluckely, almost all the Valentine's Days and Love and Friendship Days catch me alone, brokenhearted and without money. My ugly ex-girlfriend is now with a "Brazilian Male Top Model", my roommate married with the love of her life (Hooray!), my friends are in love (or without love but not looking), and it seems like every pretty woman is married or has a boyfriend...
But, before I could make my annual ritual of listen "It must have been love" of Roxette and, armed with a big reserve of ice cream, see "Love actually" and curse the fate, the opportunity knocks and I have a first date. A blind date. In Valentine´s Day. And she wants a gift (A GIFT? WTF?) And a special one. I'm so excited. What is the emoticon for "sarcasm"?
I don't have money, but I have trash in my workshop. So, I can make something that lasts more than flowers and chocolates and maybe, could be in my date's desk. And who knows? Maybe she will give it to her new boyfriend (maybe another Brazilian) when she becomes my ex.
Step 1: I got a trash on you!!!
First, remember sensei Adam and master Jamie, and be ready for the loose engineering. What is that? Be flexible. Use the things you have near, in unconventinal ways. I love ecodesign, and I store a big amount of plastic trash. I suggest these materials because I have the stuff in my workshop. But if you don't have a damaged motion sensor and a cup, use broken toys, damaged houseware, computer pieces, etc. In the end of this instructable, I will suggest alternative ideas.
Note: I'm a Spanish speaker. So, I'll try the best to name the stuff in an understandable way for all.
2 Oven knobs
4 iron pieces for picture frame
2 small iron angles
1 plastic cup
1 damaged motion sensor (you know, the one for automatically turno on the lights)
2 alligator clips
2 big blinking LEDs
2 resistors 220 ohm (red red brown gold) (optional)
1 AA Battery box
2 AA Batteries
2 Joystick vents (or any vent, like the used in the darts of toy guns)
50 cm of copper wire
thin rubber hose for covering the copper wire
screws and nuts
And our always trustable Dremel Rotary Tool (Hmmmm... I will collect money for the publicity)
