Help with 555 circuit.

Well, I have got the 38khz distance sensor working in picaxe form.

Here

Here

Now I am trying to wire-up a stand-alone unit with a 556. Now I know this is a RTF(data sheet) moment and I know the resistor/resistor*cap/2 (or whatever) equation, but the final circuit is still above my head. Are there any of you circuit guys out there that can do a little drawing for me? Maybe with a couple pots for fine adjustment? I plan on the final output going into a picaxe using the pulse-in command.

Thanks in advance.

Using PiFace but still using I2C

I got a PiFace Display in the mail not too long ago, and just cracked it open.
I got it as a tester to write a review, because I wanted the LED display and the infrared on it.

Does anyone use programming code ;"C" ?

 

 I'm pretty new to this site and robotics, programming e.t.c.

 If there's anyone who is good with programming language; "C" , then go on this site so that  everyone's on the same track with programming and stuff. Post videos or pics of robots or circuits with explanations, because, I know from my experience that I get most of my ideas from other people.

Zezinho, the poser - interactive installation

This is the final result of the first stage of this project. An installation where zezinho calls for visitors and when a visitor reachs the mixing controllers he waits for new poses.
