Asked — Edited
have 2 ir recievers from my wall-e project. Looking to make a cheap/nearly free home base ir reciever.
Could they be hacked up to work with the ez-b and my laptop(and extention cables from my laptop)?
Could anyone point me towards a post similar to this?

THE TSOP4840 is a replacement,now to use it ,its not easy
first you need a IR TRANSMITTER and it ,second on the receiver side TSOP4840 there are 3 wires red 5 volts ,gnd and white output,IT HAS LIKE A SERIAL OUTPUT or PWM ,depending on the input
On output you need something to read PWM output or a circuit like the sharp IR sensor that reads distance to analog output
I am getting ready to work on a design using that type of receiver,its kinda hard
Reason is that so far EZB doesnt read pwm values,thinking it might use the same pins at the sonar
called ECHO ,but DJ hasent made any script to read the values
TAKE a look at the pololu beacon circuit it uses that receiver and it talks about how it works
I am electronic engineer,so desiging circuit super easy for me
The Receiver Circuit:
Receiving data from Fire-Stick II is quick & painless. The only component necessary to receive data is a
single infrared detector module. With the lens of the (PNA4602M) Panasonic infrared detector facing you -
the left pin is the data output pin. Connect this pin directly to any free I/O-pin you have available on the
receiving Stamp, PIC or other microcontroller.
The center pin connects to power supply ground. The remaining pin on the right side connects to +5 volts
DC. Do not exceed 5 volts supply for the detector module circuit.
On the driver circuit you need to know the right pwm and pulse for it to work
Using 2 only gives you about -45 and + 45 deg ,to guide the robot you need a 3rd to have it go straight or 4 is even better
it alot of different ideas
there are over 50 pages just to let you know,i did print all of it about 5 years ago
When i was really into the finding home base designs and testing all types
IR DOCKING DESIGNS
IT talks about why the omnicone is so very important for docking
on the POLOLU IR BEACON is the same as a omnicone
her is my post a i did while back on the POLOLU IR BEACON design
finding home base with IR
TSOL7200 high power IR DIODE
TSOL7200 IR DIODE
ANY other help on this i can do,since i designs these types
ON YOUR design or same as the one i am making , the EZB can read the PWM value to control the servo's for docking
only differnce my circuit is that it does 360 deg soyou get a better docking hook up
YOUR will work as long notthing in the path of IR beams and close to the home base
I know my info is very technical ,but i try to put in lawmans terms as it called for others to understand
How this works will be able to help i think.
So read pwm values from the receiver.
and just give the tranciever power?(doesnt require serial connection)
here is info on SET PWM for transceiver
and info on GET PWM on receiver
EZ b script manual
now on PWM value for transceiver i need to test the value on the POLOLU IR beacon beacon board
if you look at the circuit you can see the simple drive circuit that is needed
