Surkue = Surkut. (sorry) Old upload from my former Channel Radioam232 in 2009. A 7400 Chip is used as a clock generator (schematic not visible) but a second 7400 (schematic visible) is used as a driver/shift register for 4 yellow leds. Schematic is in the video and quite clear. I have to build it completely anew now (7 years later, 21 okt 2016) to give a better explanation, but I don't have enough time, so do some experiments when you want to use the schematic.

It is revealing logic TTL (means Transistor to Transistor Logic) Chips ad (thus) very interesting because of its understandable logic using 0 (logic one, the O voltage differs somewhat) and 5 V (also the logic 1 goes between Voltage borders, study it.

All the videos hat I have published on You Tube can be found via my Channel Trailer Radiofun232 on Youtube: Link is

In thematic order you can find these video’s under the “comments” section.

My books about electronics are available via the website from “Lulu”, search for author “Ko Tilman” there. My books are also available via Barnes and Noble and via Amazon.

Regarding all my video’s: I constantly keep them actual, so the original video’s with the most recent information are always on YouTube. That is the source, and search there. When my video’s are reproduced or re-edited on other websites/channels you cannot be sure about the original content (=really working electronics) and important adaptations to the circuits.
