Mousebot Revisited

Step 10 Finish up making connections

Connect pin 13 of the relay to the left motor and pin 4 of the relay to the right motor. Now connect pin 5 of the IC (brown wire in picture) to the ground node of both motors. If you arent sure which side is + and which - on you motor connect it to a battery and observe the direction of the spin. The right motor should spin clockwise if you are looking at the wheel and the left should spin counter-clockwise.

Locate the wire coming from IC pin 2 (green) to the + lead of the left eyestalk and IC pin 3 (blue) to the + lead of the right eyestalk. Then wire the 1k resistor to the + voltage rail.

Hook up the battery by soldering the black wire on the battery cap to the negative voltage rail. Connect the red wire on the battery cap to the switch and then connect the switch back to the + voltage rail.

Replace the cover of the mouse and then cut a thin strip of your bumper material (CD) with the hacksaw. Attach the strip with epoxy or hot glue on one side so that wherever you apply pressure the button clicks. Once you have the strip attached give yourself a pat on the back, you're done.

Flip the switch and enjoy.

Hi, i plan to do this for my project. do you think you can provide me with the circuit diagram? It would be really great if i could hv the circuit diagram. pls help :)

[luudvig]

I found it alot more esy to solder everything to a circuit board, here's a pic of my mousebot's brain.. :P

[kiran1997]

Dude thnx for ur Idea , i have my junkbot ready and running thnx man!!

[Chris45]

How did you do the training wheels?

[pratik1234]

robart to ban gaya but chala nahi

[Chowmix12]

mera ke liya bhi aisa hi hua

[tompapa]

 Thank for all your help,,.but i wants to add Infrared detector so that my mouse can detect any infrared light in room..and turn towards it..plz help me..

[rajsekhar291]

This is too complicated for me .can u plz draw a circuit diagram of this with all the pin numbers and connections clearly mentioned.PLz

This is the corrected circuit diagram of Mousey from the Make Magazine publishing.

the toggle switch appears to be a master power switch :)

[baldo]

let's see some video!!!

[pobturtle]

There should be a video.

[pobturtle]

on youtube

[weberf]

this is really cool but my mouse is 2 small and it just goes in circles but the electronics work perfectly

[chemy999]

try switching the wires on the motor that is on the outside when it spins

[Shrinking_Universe]

My mouse has a scroller on the top. Will this block anyway of making this or will it work?

[chemy999]

it will work

[Shrinking_Universe]

Is there a difference between the toggle switch, because theres one with 4 legs and theres one with 2 legs. I bought the 2 legged ones, but is there a difference?

[Shrinking_Universe]

Oh okay, thank you.

[stevie1]

not really the one with four legs is just for if u need to turn on or off two things simulatiousely.

[Shrinking_Universe]

I broke the legs off my IR emitters. Is there any way it will stil work?

[TechnoMancer]

try finding another mouse, its almost impossible to solder on wires when the pins are broken off flush

[Doveman]

Where did u find ur mouse at? Also, can a Compaq mouce work?

[Darkshot]

they have some mice at the dollar tree :) thats were i bought mine

[Doveman]

How many pins do the relay have to have? Where can I get a DPDT 5v Relay, and a LM386 op-amp? I can't find these at [http://http//www.radioshack.com/ Radioshack]<br/>

[The_EN6INEER]

Try mouser.com or Fry's Electronics (if you are lucky enough to have one around you). Radio Shack, no offense to anyone, is simply a cell phone and speaker outlet now.

[Gemologist]

Is there a slightly more complicated version that is possible to make with 4 motors, wheels?

[APeiceOfPoo]

Do you think you can make a movie of it working?

[debugger]

u should make a diagram of all the points that canect cause i cant see them in the picture plz
