Too Much Over-optimization Is Never Enough!

A discussion came up on the Hackaday Discord PCB design channel about resistor networks, and it got me thinking about whether we (the hacker community) use them in designs or not. These handy devic…

Vectorscope KiCad Redrawing Project

When I saw this year’s Supercon Vectorscope badge, I decided that I had to build one for myself. Since I couldn’t attend in-person, I immediately got the PCBs and parts on order. Noting that the Gi…

Try It Out

It’s like Star Wars versus Star Trek at a SciFi convention, or asking creamy or chunky at the National Peanut Butter Appreciation Festival. (OK, we made that one up.) When Jenny reviewed the 1.0 ve…
