Search for the original Moog schematic
The hunt for the original Moog schematic, which, as it turns out, wasn’t terribly hard to find… just not easy to source parts for and build….
I was watching How Telephone Phreaking Worked when at 3:01, I saw this large Gameboy display
Following on from Sequence Dancing – Schmitt_trigger_NAND_implementation, and the number of issues with that schematic (from CMOS 4017 Based 8 Step Sequencer)…
Basically, the HOLD function of the schematic above does not work:
I purchased from Lissony 24Values TO-92 Transistor Assortment Assorted Kit Each BC327 BC337 BC517 BC547 BC548 BC549 2N2222 3906 3904 5401 5551 C945 1015, £4.33+£3.25, which is still to arrive.
However, are they actually economical?
After having seen some people doing this in the canals around Leicester and having read this article on the BBC news, The hidden dangers of magnet fishing, I thought I’d look into it.
There are a range of magnet sizes/strengths to choose from, with cost obviously increasing with strength, so which one do you need?
