Here we are in October, improbably enough, and while the leaves start to fall as the goblins begin to gather, Elliot and Dan took a break from the madness to talk about all the wonderful hacks that graced our pages this week. If there was a theme this week, it was long-term projects, like the multiple years one hacker spent going down dead ends in the quest for DIY metal 3D printing. Not to be outdone, another hacker spent seven years building a mirrorless digital camera that looks like a commercial product. And getting a solderless PCB to do the blinkenlight thing took a long time too.

Looking to eliminate stringing in your 3D prints? Then you’ll want to avoid the “pause and attach” approach, which intentionally creates strings in your prints. Wondering if you can 3D print bearings? You can, but you probably shouldn’t unless you have a particular use in mind. And what happens when you have an infinitely large supply of Lego? Why, you build a Turing machine on steroids, of course.

Finally, we take a look at this week’s “Can’t-Miss” articles with a look into plastic recycling and why we can’t have nice things yet, and we take a trip out into orbit and examine the ins and outs of Lagrange points.

And a little mea culpa from the editing desk: Sorry the podcast is coming out late this week. Audacity ate my files. If you’re ever in a similar circumstance, you can probably halfway save your bacon with audacity-project-tools. Ask me how I know.
