It’s time for a Cool Tool review. This week, I’m going to show you the tagger’s alternative to the Sharpie, the Krink K-70 permanent marker. I got this for $8 on Amazon, and if you’re curious to try one out, the Amazon link in the description helps support my videos and the Cool Tools blog.

I learned about the Robert Larson 800-2875 Plastic Center Finder (Amazon link) from maker Ben Light, who uses it to drill out the center in the tin can robots he builds. Online, I see a lot of videos of jewelry designers using these. Woodworkers use them on finding centers on dowels or centering up work to chuck into a lathe.

This week on Maker Update, an automatic dice spinner, a desktop CT scanner, what taggers can teach us about permanent markers, and powering your Raspberry Pi from lithium iron phosphate. This week’s Cool Tool is the Krink K-70 Permanent Ink Marker.
