Mega168 bot and servo control

At the picture you can see my bot improved. All wires hided inside the box. Scan algorithm was improved as well. Now I can release him for long autonomous traveling inside my house.

For servo coding I used my USB scope DSO-2090. All pulses was measured perfect.

This pulse controls the servo position. 1 ms - the servo edge position.

  

USB Scope DSO-2090

Today I received USB scope DSO-2090. I bought it on EBay instead of my old analog scope. I must tell - Great thing. User friendly software interface. Bandwidth declared as 40 MHz - it seems to be true. I don't need greater. It works in real time despite of USB connection bandwith limit. You can auto set up all parameters (voltage and time) or you can set up them manually. You can see FFT spectrum as well.

Here is a box

And here are things inside the box. Scope, CD, short instruction, USB cable and 2 probes

And here I tried to reach scope limit. You can see signal around 3-4 MHz

You don't see squares because of high bandwith. With lower bandwith signal is pretty stright. All controls are like in analog scope. And you can measure everything - frequensy, rising time, duty cycle etc.
