Hello people!-- Yeah I know you're completely fed up That every chapter looks the same
...That it seems like Nintendo is my sponsor But no, it's not like that!
And I promise that this is going to be the last chapter relates with this silly thing
emmm
Until we create a robot that Can be controlled with this thing
Yeah, it'd be cool But in the meantime let's check
...the materials for today
...are:
- A Wii Remote Controller - A Computer with bluetooth
...again
- A 10 Ohm Resistor here are two, but just one is needed
- 4 Infrared LEDs that in this case
...are going to be of 1,2 Volt - A USB Standard-A plug cable
...unused or cut off
...or taken from a broken mouse
...or whatever
Of any device
The thing is that wee need a USB plug
...that this part and the rest should work correctly
- A Hanger, broken o useful and it must have this things
OK?
- And of course all the arsenal of rubbish you can find in your electronic lab
like for example the Soldering Iron, Tin, Soldering Flux...
...the Nail Clipper, the little Cables blah blah blah
The deodorant shouldn't be there, anyway
The first thing you're going to do is to cut the ends of the hanger
These ends where are these...
...kind of clothes pegs
These thing, right?
And you're going to leave
...a small piece
...of the hanger so
so we can put our LEDs by making four little perforations
and in every perforation, we'll pass one LED lead frame through it
Two Infrared LEDs are going to be
...in each of
...these pegs
Why? Because with these pegs we're going to make our DIY SensorBar
But what is the great thing about the SensorBar? It is that the distance between the LEDs could be variable
because they're separated
Either way
you could take it from a
independent power supply
with batteries, for instance But in this case
we're going to have to connect them with a cable we'll give them a tolerance so it can have...
...certain distance
But it'll be variable, so we can regulate it
and later we're going to connect this cable with the USB plug cable that we've got
so we'll be able to connect all these with the computer
Because many of you ask me
...for an explanation of that
I saw this hanger with this little saw you see here
...now obviously
you can use another device you think is more appropriate to do it
And this is called "breaking our soldering iron"
la la la la la la na na na na na
- You tell me when the... - Eeh... yeah...
Tell me when it passes to the other side
Yes, it has passed Oh the smoke
- Nothing is going to happen to you. - It passed

It passed It looks like a lancet
OK, so...
ee...
We've already got four perforations
...and the idea is that in every perforation
...passes a lead frame
...of the Infrared LEDs
in this way
like you can appreciate What a beauty!
- Yes. Is it covered? - Looks like
The idea is that you make four perforations I did them with a soldering iron and
...it is really mediocre, but if you have a Dremel, a one millimetre drill bit, or something similar
and if you have a drill you can do it with that
and it's going to be more descent than this junk
Then you put the LEDs
The idea is that
every lead frame in every hole
every perforation in this way
After this we're going to cut, bend and solder ...and it'll be great


Well, here we can see how it is
...the soldering
...of our SensorBar
The four LEDs are soldered as a series circuit
...with a resistor in the end
This is important: the USB plug cable ...the red one
according to the USB Standard
it should go with 5 Volts
the electric current
...and the black cable to the mass
that is to say
...to the negative
The other two cables carry information, so we isolate them
Emm...
Here it is the ohm resistor
Everything is connected as a series circuit... maybe you can't see it very well, but because it's a mess.
That is what we can see here
The idea is that you can adjust this,
the more esthetical, the better
It is no the most beautiful thing in the world but... it's something
We hope it works correctly
The idea is that in the back where all the soldering and connections go
you fill in with silicone caulk, so it can work as an agglutinative insulator
with this
it'll prevent the connections touch each other
But me, not having silicone caulk, I'm going to use insulating tape
It works too
Now we have the SensorBar finished on the computer
It's not the most pretty thing
mainly because of the insulating tape I used
but it's quite functional
and it works better than the other SensorBar
I believe it's because of the distance and the intensity, 'cause it has two LEDs
in each extreme
We don't have problems with the variation of the power supply
Because before, the battery used to run out and the luminosity used to fade out
Now there's no problems because it's connected by USB man!
with its appropriate resistor and everything perfect
so now we've got a SensorBar
that really can kick asses
Here we've got our SensorBar up and running
In fact, it works better than the last SensorBar we made before
- Now we can see how... - How is the thing? Who is the host of this thing?
- I-I- I don't... - Just go ahead!
Go ahead!


Are you recording?
em...
Let's make a DIY Robot?
- Really? - No! hahahaha
