My Arduino Robots

Category : Arduino, Electronics

Thought I write some about my two robot projects! They both use a Modified Pico, since it’s the smallest Arduino I’ve found. And it also fits on a small breadboard!

Botty 2:

This is the most advanced robot I’ve built, but it’s not nearly finished.

It’s current task is to drive straight forward until it senses a object with it’s IR-sensor, then drive away from it until it’s cleared, and continue in that direction. Really simple šŸ˜›

It uses a Sharp-IR sensor, mounted ontop of a servo, so it scans the horizon while driving forward. The sonar in the picture isn’t in use, since I actually like the IR sensor better.

BewBit:

Simple and yet fun to make arduino bot. Just follows the strongest light source. Using two LDRs, a modified pico and 1xAA and 2xAA battery packs, to give out 4,5 volts. Just enough to power theSN754410 and motors. But it gets around. It also includes a low-voltage alarm, which beeps when the voltage goes low.

Had a little accident, it drove over a carpet, or it came about 30cm into it and some funny gear-whining noise came šŸ˜› A lot of hair in the gearbox, had to take it apart and clean it.

Future plans:

* Crash sensor, a small micro switch in front.
* Speaker, plays sound according to light source šŸ˜›
* Better code

Installing WMP11 without genuine advantage or validation check

Category : Windows

We all know when installing windows media player 11 you need to validate your copy of windows xp. Or at least you will know when trying to :P. And if you for some reason fails that validating, you can’t install it. Now here is how to bypass that šŸ™‚

1. Download WMP11 from FileHippo:
http://filehippo.com/download_windows_media_player/

2. Extract the .exe file somewhere:

Left click on the wmp11-windowsxp-x86-enu.exe, and select Extract here, or someplace you want. Using WinRar or some other program.

3. Run wmp11.exe:

This is actually the install of the wmp11 without validation šŸ˜›

Running this file will bring the installation window for wmp11 right up. And now it’s just to follow the steps from there.

4. Reboot and finished!

Yes, at the end of the installation in step 3 it tells you to reboot. So just do that, and when it’s back up again you got a fully working windows media player without having to hassle with the validation.

EDIT: Might also add this, on some systems you need to run the other exe files in the setup package.
