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.

      NOTE: If you have a project that I don't think is for beginners (or I don't understand what it is/lacks documentation) - you'll automatically get a low score from me even though your project is really cool.
