I find scoring both sides helps a lot too on thicker boards.

I'm pretty sure this is like 10 times easier than what I had been doing. Thanks!

I have been pulling out my hack saw or Dremel for YEARS. Never thought it would be that easy. Totally using this next time. THANKS!!

Wait, I don't need to ruin my flush cutters??

But, "resizing" suggest both ways! How do you make the boards BIGGER?

Useful tip!

These tips are 👍 great.

So basically the same procedure as drywall, except with a bit more force. Also, voila, ersatz castellated vias (they probably don't work, don't trust them). SparkFun has a "snappable protoboard" which is essentially a pre-scored perf board. I tried it, it's not bad, but you end up with a lot of leftover bits and the quality of the pads wasn't great (they oxidized within a year, ugh). Also if you make a big board out of it, it would tend to bow a little in the vise, so that was fun too. The more I use perf boards like this, the more I appreciate circuit CAD and PCB fab services. Sure, I have to wait a couple of weeks for the boards, but I can size them the way I want beforehand.

Is it better to cut across the center of the pads like shown in the video or between them? I've always done between, but maybe through the center is better

Using a jwellers saw is much more fast and easier

Does no one mention that this white board looks like a breadboard 😂
