Diving into the world of digital electronics !
For almost 8 months now, I’ve been experimenting with the base and expansion set.
Although I still have a plentiful of ideas with this set, I felt the time had come to explore the digital world.
What better way is there than to experiment With the Lectron Digital set 1007 ?
So, I unpacked the still wrapped digital expansion set A (as mentioned by Michael to distinguish between the 1007 and 1107 sets).
Set A consists of a whopping 3 trays with lots of new modules to explore !
Set A (1007) is the normal Digital lab.
Set B (1107) is also a Digital lab, but uses lesser and different components and is primarily designed to be used with the Lectron AG school system.
Well, here’s an picture of the Start, expansion set and digital lab.
Ready to dive into the exiting world of digital electronics !

Love the photo of the layout and can’t wait to see what creative ideas and new circuits you come up with!

My first impressions ….
So, I started the first digital experiments. Battery fully charged (yes, I use a rechargeable 9V battery) and opening the manual.
It all starts with the beginnings, basic AND circuits with switches.
So far, so good. Everything well explained with much detailed information.
The lamp is always connected with a protective 47 Ohm resistor. Good job Lectron !
But oh, a few experiments later the relay is used without a protective 120 Ohm resistor (see the topic about this here on the forum).
Since the relay used is a 5V type, it’s coil could be damaged when using 9V ! A resistor of 120 Ohm in series protects this coil, so be sure to always use it for the rest of the experiments !
Moving on to the AND gate, made up with semiconductors.
Oh my, these circuits use 2 Si diodes and there’s only 1 (the diode of the basic set) and an extra is not included with the digital 1007 set.
Luckily, there’s one in the Legacy set that I can use.
No problem, but it would be nice if it was included.
The next circuits are about OR, NOR, NAND and impedance adapters with very detailed explanation. Way to go !
Aha ! EXOR gates !
This is interesting, they find many usages in everyday life. The light switches in your house are very good examples and the manual of the 1007 set gives many good examples and circuits.
To be continued !
