Introduction: Electronic WorldMap

Hi Folks,

here's a stuff i decided to make because i couldn't find any that suits me.

It's the first electronic thing i've made, so that's not the better way to do it, because i knew nothing before making it ; i think that a professional would rather have a sepukku than doing this like a did, but nevermind, it was for fun.

I wanted to have an electronic planisphere that could show me countries i've been to. But i wanted to have something looking engough good so that i could have it in my room.

Moreover, i wanted an lcd screen that could print the country and the cities i've visited. The prupose is to be a tool (geography) and have some fun while building it.

I started to test some coding that will do the job, and posted it on my blog, to keep the phases of conception.

Here is what i needed to build this :

- an ikea frame (that's why i consider it as an ikehack :) )

- a worldmap (tough one, plastic one)

- blue leds (number depends on the countries)

- shift registers (depends on number of leds)

- an arduino Uno

- an lcd 16*2 (blue screen)

- a 9v battery

- a switch (stolen from a lamp :) )

- boards or breadboards

- wires

- a soldering iron

- tin

- power cable for battery with arduino link

- thermo retractable tape

- some patience

First, i had to get the leds through the map, and cut the map so that the lcd screen can appear ; like this :

Then i soldered the wires on the leds : two colours corresponding for anode and cathode

Then i cut the switch, made holes in the frame to let the cable go through, and had to link it to the power cable.

Next step was to solder the lcd screen,

Fix everything on the board, and test .

You can find the full steps and the code on

Thanks for watching, hope you'll find this not too bad. I'll post the full work and all steps when 'ill get some rest, too much work for the moment, but i wanted to share this idea, which is quite simple

Have a nice day,
