Description
LED ring on logic chips
A printed circuit board for assembling a simple LED flasher. The scheme was published in the journal Radio number 11 in 1986. I assembled this construction on the radio hobby shool while still a schoolboy. She remembered to me her simplicity, and the childish delight of the hand-assembled, working device.
The video briefly tells about this scheme, and about several improvements and modifications that were published in subsequent issues of the journal.
