How to provide power to keyboard and logger without computer

[mpardinho]

hardware logger

Does a k/b need to initialized or something when its plugged in? This is what I have...


+5V Power (**broken link removed**)

----> +5V connected to PIN4 / GRND connected to PIN3 of male PS2 (https://www.networktechinc.com/ps2-prots.html) connector... then PS2 hardware key logger connected (https://www.keelog.com/diy.html) ... then keyboard.... but pressing any buttons doesnt work... how do i know its getting power and actually turning on? Shouldt it work in theory....?


Im trying to make the keylogger store data without a computer... so that i can retrieve it later... almost like a notepad... cept im walking around with a keyboard and no computer a batter at the end and a keylogger between the battery and the keyboard...


Anyways... if someone could shed some light on how I can provide power to the keyboard and the logger WITHOUT having a computer.. would be great...


i found ..look at page 39 and 40 of this picaxe manual:
hxxp://www.rev-ed.co.uk/docs/picaxe_manual2.pdf

but i need other chip...in my country not have

Thanks!

Re: hardware logger

You can simply use a 5V regulator, that will power both the keyboard and your microcontroller. There is nothing special about the micro, you can use pretty much any micro you have available. You just need to toggle the clock line and watch the data line. Any micro can do that.
