New Revenue Sharing

Posted by ozirock on November 9, 2011 at 4:05 PM Comments comments (1)

Hey Guy's

I'm struggling to find time to add to the website so I've added a section for people to add projects. As an incentive you can enter some adsense code and hopefully generate a bit of revenue for yourself. You can find a discussion about this on the forum here. Or you can find the place to submit your projects here.

Successful test of new motor controller!

Posted by ozirock on October 30, 2010 at 5:40 AM Comments comments (0)

We've had some success with a new design for the motor controller which is much simpler than the original. This design only uses an 8 channel ALLEGRO MICROSYSTEMS driver source, a few BD135 NPN Transistors and a few 125 ohm resistors. 

To control each motor takes 2 channels of the driver source, two resistors and two transistors which means the final design will be a very simple build.

Unlike the original design, which had the PIC microcontroller built into the board, this design will simply be a controller board with eight inputs and outputs for four motors. The PIC will then be created on it's own board which should make future robots easier to build by just rearranging these boards.

Diagrams and pictures should be following soon,

All the best,

Controlling servos with a 555 timer

I've found a bit of information on using a 555 timer to control a servo, could be very useful if your planning on making any humanoid style robots.

New Forum

Posted by ozirock on October 20, 2010 at 12:25 PM Comments comments (0)

Hello All,

I decided to try and replace the forum as there was no notification of new posts and reply's to threads which made things very difficult. I was able to find a forum which integrates with Facebook so it should be very easy to keep up to date on new threads and posts.

You'll find the new forum here

Or alternatively on Facebook here, don't forget to hit the like button and spread the word.

A few electronic components for sale!

Posted by ozirock on August 21, 2010 at 7:49 AM Comments comments (0)

Hello All,

I'm heading back to uni soon so I taught it wouldn't be a terrible idea to try and sell a few components since I usually by them in bulk to save on the shipping.

I have quite a collection of resistors, leds, transistors and other small things like that so if your looking for some components it may be cheaper to get them through me and then you don't have to buy in bulk yourself thus making it cheaper.

The shipping cost is €2.30 for Ireland and €2.80 to everywhere else for a small package.

So if your working on a project and need a few parts let me know and I'll see if I can help at all.

Hopefully this will help some of you guys as well as myself.



New App on Webs

Posted by ozirock on August 18, 2010 at 3:53 PM Comments comments (0)

Hello All,

I've just added a new webs app which links us with a company called CafePress, we're able to design some t-shirts and that. Does anyone have any ideas for logos?

I'll try make as many as I'm allowed, not sure what the limit is, thanks for the help :)

You can see the few designs here.
