Heute habe ich gesehen wie wichtig ein gutes Oszilloskop ist, deswegen möchte ich mir jetzt eins kaufen.

But i am not sure, should i buy it? On the one hand i can use the oscilloscope in school (but i can't use it very often). On the other hand i want to have my own oscilloscope (But it's very expensive)

Rfid emultor and Scope
the_f_halex
Heute habe ich meinen RFID emulator mit in die Schule genommen. Unsere Schule hat ein sehr gutes Digitales oszilloskop. Aber nach einer Stunde vergeblicher Suche des Signals habe ich aufgegeben. Man hat nur Störungen und ein komisches Auschwingen der Spule alle 20ms gesehen.

Today I have took my RFID emulator to school. Our school has a very good digital oscilloscope. But after an hour of fruitless search for the signal I gave up. It has been seen only faults and a strange outswing of the coil every 20ms.



ID generator

I have finished the ID generator. It generates an EM4001 compatible ID.
It calculates the row and the column parity bits from any Rfid Data.

Now my PCB's are there. It tooks more than 2weeks to ship them
from Bulgaria to Germany.

I had bought the them at Bilex in Bulgaria.

3D eagle
the_f_halex
With 3Deagle you can convert eagle .brd files to 3D .pov files.
After you have routed the board you must execute the 3d41 ULP
These ULP produce the pov. file.

And with PovRay you can render the file.

You can produce a picture of you're board or even a movie.

The RS232 connection works!

The RS232 connection to my emulator works!

Now i am  going to make a BrutForce skript.



Avr Slax
the_f_halex
I have found this: http://www.lost-byte.de/avrslax.php

It's an Avr Linux that has the Avr Gcc compiler onboard and the burning tools for the Avr's
.
It based on Slax.

I hope it's easier with Avr Slax to compile avr-gcc programs :)
