hi
im trying to modify a "useless machine" - the one that sticks an arm up and switches itself off.

the aim is to make my cars GPS unit pop up (stand up @ 90 degrees) and "lay back down?" when i switch the ignition on and off.

using modified servo's or gear boxes i can sort the mechanics out however, my major complication is the electronics- switching the power off once the unit is upright, reversing the power and switching the power off once the unit is back down again.

you may ask why all the effort , main reason is because it would be cool, then there's the security (people breaking into your car to steal it which happens often)

this may seem like a stupid idea but im a diy enthusiast.

PLEASE HELP
ANY FEEDBACK WOULD BE GREATLY APPRECIATED!!!

I think this allows you to interface your cars "electronics".

If it does connect it to the arduinos RX and TX pins.... And then connect the arduino to the motor and just program it with some "if" commands, and actually that's a cool project, Its not stupid.

Use a "analog input" and a "while",

const int moisture = A0; //or what ever pin you want

//other code

void setup(){

pinMode(moisture, INPUT);

//other code

}

void loop(){

while(moisture < ????){

//pump HIGH code

}

while(moisture > ????){

//pump LOW code

}

}

Is that your useless machine I saw on Think Geek's website? Congratulations! I like your wooden box better than their kit, but it's great that your genius idea is now available to the thinking masses... I hope they distribute your candle powered LED lamp too. I never thought the useless machine could be topped, but you did it!

Nope different useless machine. I was not the first to make one. Was first posted the author saskview (who also used a wooden box). I was just asked to make one for display at Maker Faire. Nonetheless, perhaps one of these days I will be able to turn one of these things into a nonsensical product. So far no luck.
