Keying with a Mouse !

Quite a few operators have been talking about how to use a mouse for a key, on cwcom.  the obvious way is to check the "mouse" as a selection for "morse input" and then select Iambic on the Morse Key part of the "Morse Key" tab, on the "configuration window"..

This works, to a point.. but you MUST keep the mouse cursor in the little black box in the top left of the main screen... tricky, ! !... it keeps moving about when you key... so, a quick and simple solution to that, is to have a second mouse plugged into another usb port, and secure that to the desk top, with some blue tack, to keep the cursor in the box..   !.

.......again, it works.. however, what if you are not so good with a "paddle/iambic" type of keying?  can you connect a straight key to the computer in the same way?

The answer is YES!.. you can...

You will still need two "mouses" or mice !.. one to be the "operational mouse" as for normal usage, call this mouse number 1... and the second mouse, mouse number 2,  to be "hacked" so that it can be used for keying on a straight key.

ok... how to....

.....How to make the mouse number 2 into a USB keying device for a straight key. ... first remove the little PCB


CLICK ON THE PICS TO ENLARGE THEM....  ! 





inside the mouse, and you will see a small pcb,... remove this,.. and have a look at it...




Turn it over,.... and with some blutack, (or you could use some tape )... secure it to the bench , for ease of soldering your wires.....  ...  ..

                         I used a roll of insulating tape , blobs of blutack ...

From my pic, at the bottom end you can see two pairs of  solder points... these are the contacts of the right and left buttons on the mouse... this gives us some nice convenient points, on the circuit board beneath each button.... to solder a pair of wires to one pair of points...

EDIT EDIT... instead of soldering the wires permanently to your morse key, you could make a short connection to an in-line stereo socket, and then just plug your morse key into that,... this will also give you the opportunity, to use the mouse as a mouse, if you needed to.. and also allows different keys to be connected via the mouse adapter...
 
You need to determine your wiring, and connection points...


     Using a spare 3.5 mm (or whatever size you have on your key) jack,  determine by "continuity test" using a meter or battery & bulb, which parts of the jack connect to which solder point .

... insert the jack into the  "line socket"... and by a similar process, you can determine the layout of the solder points on the line socket. 

     do a drawing, and write down your findings... you will probably need to refer to this quite often ! ! ..

 Using a suitable short length of 3 core wire ( if it has four, cut one off short ! ).. and solder them to the points on the socket.... 




Solder the other end to the mouse pcb.... remember to put the sleeve on the line jack first ! !! ..

 You will need to make sure that there is plenty of room on the shell of the mouse for two sets of wires to exit... so use a sharp craft knife, or penknife to enlarge both halves of the casing...

before final re-assembly, it is advisable to double check that it is all working fine....   plug in your mouse number 2... ( this one )....




      check that you have selected IAMBIC  on the configuration window,.. and also double check, that you have "COMPORT" selected.

 and then you can get mouse number 1 into position with the cursor in the little black box, top left of screen... and if you want... you could stick it down with some bluetack, to keep it in position...






Once you have confirmed that your soldering is absolutely brilliant,.. i.e. it works ! !.. then you can put it all together and make a nice neat job of it....





here is a pic of how a straight key could be connected, direct to the mouse pcb.

 and "Hey Presto".. you can key with the mouse number 2... whilst mouse number 1 does its job by staying put in the black box..


WARNING...

I hope that helps you to do the necessary work...

 as with all my information, you work on things at your own risk... it works for me...

 I hope it works well for you...
