Philips EE3023

The EE3xxx series is the last Electronic Engineer kit only published by Philips. After this series the name changed to ABC and the products were quickly licensed to Schuco.

I have the EE3023 box in a very good state..

Video oscilloscope

What makes this box interesting is that it allows to use a normal television for the oscilloscope projects in the EE1007/EE2007/6105 that required a oscilloscope tube.
It has therefore a video signal generator, quite simple with some cmos IC's, on a special PCB. See the circuit diagram on the right, quite simple!
Dont expect a real oscilloscope, it is quite limited in frequencies it can show. But the educational value is good, to see the electronic signals is great.

The idea for such a circuity is not new and not original. Already in 1977, years before this kit was published, I published an article to build this with the title Videoscoop in the dutch electronics magazine Radio Bulletin based on exact the same idea!
