How To Design A Low Cost Probe-Oscilloscope
https://hackaday.com/2019/12/16/how-to-design-a-low-cost-probe-oscilloscope/
[Mark Omo] sends in his write up on the design of what should hopefully be a sub-$100 oscilloscope in a probe.
Many problems in engineering can be solved simply by throwing money at the them. It’s really when you start to apply constraints that the real innovation happens. The Probe-Scope …read more (https://hackaday.com/2019/12/16/how-to-design-a-low-cost-probe-oscilloscope/)

Busy Box Beats Baby’s Boredom
https://hackaday.com/2019/12/16/busy-box-beats-babys-boredom/
We would love to be a fly on the wall Christmas morning to see [Wilksyonreddit]’s kid tear the paper off of this adult-level busy box. Can you imagine the unbridled glee? It should certainly make the arduous six-month build worth the trouble. Here’s hoping the walls are sturdy, because we …read more (https://hackaday.com/2019/12/16/busy-box-beats-babys-boredom/)

Lego Machine Uses Machine Learning To Sort Itself Out
https://hackaday.com/2019/12/16/lego-machine-uses-machine-learning-to-sort-itself-out/
In our opinion, the primary evidence of a properly lived childhood is an enormous box of every conceivable Lego piece, from simple bricks to girders and gears, all with a small town’s worth of minifigs swimming through it.

https://hackaday.com/2019/12/16/3d-printed-goggles-let-r-o-b-see-into-the-bluetooth-world/
We admit that a hack enabling a 34-year-old video game peripheral to be controlled by a mobile app wasn’t something we were expecting to see today, but if controlling something with something else isn’t the definition of a classic hack, we don’t know what is.

Humongous 3D Printer Produces Boat And Challenges
https://hackaday.com/2019/12/17/humongous-3d-printer-produces-boat-and-challenges/
We’ve seen some pretty big polymer 3D printers, but nothing quite as big as the University of Maine’s 3D printer with a 22,000 ft³ (623 m³) build volume.

Tidy Board Rework Uses Flex PCBs, No Wires
https://hackaday.com/2019/12/17/tidy-board-rework-uses-flex-pcbs-no-wires/
PCB rework for the purpose of fixing unfortunate design problems tends to involve certain things: thin wires (probably blue) to taped or glued down components, and maybe some areas of scraped-off soldermask.
