Our language is derived from Hebrew, u can say it is Hebrew sort of.
It is read from left to right as well as written.

And I am looking out for my self.

All the gangsters are now locked away. The Islanders say it's never been this safe and peaceful now that the drug dealers are away.

Here's a pic of my current project. It's one of the first traces from my PC based oscilloscope. I know it's been done thousands of times before, but I fancied getting back into PC programming and I need some kind of cheap, basic oscilloscope.
It uses the PIC ADC to store samples, then send them over serial to a Python program. It's early days and it's only about 50K samples per second and it can't store many, but I might upgrade to a better PIC later which could make it 20 times faster.

Same here,I have also started same kind of project.

This one is datalogger ,I wanted it to be real time datalogger so its sampling is very poor around 10-15 ms as right know I am using windows timer.Working for USB but I think I can't transfer data so fast, so I will store the data and then transfer to PC.Live streamming will give slow sampling rate because of windows interface.



Here is my PC based oscilloscope.Tracing 50Hz sine wave
I have stopped working on it for sometime as I am working on my datalogger...


BTW ,the hardware I started with PIC18F4520 and looking for other better options,applications prototype is with .net using C# but final one will be full native using C++ and win32.

Having lots of problem but too much fun ;)

I think I will complete it one day.

Looks pretty good already, my plan is for all the critical timing to be done in the PIC because it's much more accurate than the PC (without doing some crazy low level coding).

Yes thats what I am doing too, as I have already said the windows timer is not much good its giving me a resolution of 10ms.Right know atleast I need a resolution of 1us.I don't think my plan of using a mcu will go to far as too many parallel input for the datalogger.I think now it needs a FPGA too, thinking on it.

Hope your project is going well.

We need more guys to step up with pictures,some guys won't put
there state out there.....So kick the can guys,Nerdegutta,enjoy
your vacation more vacation pictures.The mid- summer pictures
should be coming in.

@Loosie - you keep asking for pictures but only post one of yourself? How do we know it is even you? It could be one of those that comes in a new picture frame.

Some one as famous (notorious?) as you should have tons of pictures to post.

Just kicking the can and Loosie:p

Browsing through the pictures from the vacation in the boat, my daughter caught me wearing my Steven Segal fighting face. :) Don't know why I had it on, thou...
