Hack Your Brain to Stop Overeating
https://hackaday.com/2019/09/05/hack-your-brain-to-stop-overeating/
Sometimes the easiest advice can be the hardest to follow. For example: if you want to lose weight, you must eat right and exercise. You can avoid both and still lose weight by simply eating less, but that takes willpower.

Print A Drill Press For Your Printed Circuit Boards
https://hackaday.com/2019/09/05/print-a-drill-press-for-your-printed-circuit-boards/
If you make printed circuit boards the old fashioned way by etching them yourself, you may need to drill a lot of holes; even surface-mount converts still need header pins on occasion. But, drilling these holes by hand often leads to broken drill bits, which always seems to happen with …read more (https://hackaday.com/2019/09/05/print-a-drill-press-for-your-printed-circuit-boards/)
