Electronic Worm Harvester

closeup-of-worms.jpg Having been born and raised in Minnesota — Land of 10,000 Lakes, as modestly claimed — I’ve always had a fondness for fishing. We mostly caught sunfish and walleye. Though I had a strong aversion to baiting the hook, when I saw this circuit designed by engineer Dave Johnson, who runs the website Discover Circuits, for harvesting your own bait, I just had to pass it along! Explains Dave: “When I was a kid my engineer uncle built a circuit similar to the one below. My cousin and I used it to force earth worms out of the ground to be used for fishing. It worked like a champ. Please be careful since there is high voltage at the probe tips.”
