This week on Maker Update, an analog 7-segment display, Pi Compute Module 3+, using veneer for bent wood projects, Pictionary for robots, monochrome in a can, and projection mapping your face.

This is review is for the Dremel Versa Tip butane soldering torch (Amazon link). It’s sells for around $38 on Amazon Prime. This is a portable soldering iron/heat gun/hot cutter/wood burning tool, that runs on butane. You click to light it, use the lock to keep the flame on, and then you adjust it for the temperature you need.

We’re going to take a quick look at three very different options in portable soldering irons. The point here is really just to give you a demo of each on the same table and you can draw your own conclusions on what might work best for you. 

This Bernz-O-Matic Micro Flame Torch kit sells for $30 (here it is on Amazon), which isn’t cheap for a butane torch, but let me show you why this one is special.
