Does now not the Z-axis on 3-D-printers seem a bit of – underused? I suggest, all it does is creep up a fraction of a millimeter for the reason that printer works through every slice. It may well be nice if it will artwork with the other two axes and in fact do one factor eye-catching. Which is strictly what’s happening inside the (*3*)nonplanar 3-D-printing methods being explored at the Faculty of Hamburg. Printing proceeds normally up until the end, when some changes to Slic3r allow blank toolpaths to fill inside the stairsteps and produce a blank(er) finish. It obviously may not artwork for all prints or printers, then again it’s nice to look the Z-axis finally pulling its weight.

If you want to know how one factor breaks, absolute best to talk to any person who seems inside of broken stuff for a living. [Roger Cicala] from spends a large number of time doing merely that, and he has come to some eye-catching conclusions about how electronics gear breaks. For his money, the excessive offender in camera and lens breakdowns is side-mounted buttons and jacks. The reason why is apparent whilst you think about it: portions mounted perpendicular to the ability needed to serve as them are matter to a torque. That is a matter when the one issue keeping up the part to the board is a few SMD solder pads. He covers some other eye-catching failure modes, too, and all the article is worth a discover ways to learn how not to design a robust product.

Inside the it seems that neverending quest to build the field’s worst Bitcoin mining rig, behold the 8BitCoin. It uses the 6502 processor in an Apple ][ to accomplish the important hashes, and it took a little bit of doing to port the 32-bit SHA256 routines to an 8-bit platform. However therein lies the Mod. However what about efficiency? One thing one thing warmth dying of the universe…

Contributing Editor [Tom Nardi] dropped a tip a few new online magazine for other folks like us. Dubbed (*8*)Paged Out!, the internet per thirty days ‘zine is quite a few contributed stories from hackers, programmers, retrocomputing buffs, and with regards to anyone with one factor to say. Every article is one internet web page and is formatted on the other hand the author wants to, which leads to some eye-catching layouts. You’ll be able to be in a position to check out the prevailing issue proper right here; they’re however looking for quite a few articles for the next issue, so in all probability imagine writing up one factor for them – after you put it on, finally.

Tipline stalwart [Qes] let us know about a captivating building in semiconductor manufacturing. Fairly than focused on making transistors smaller, a bunch at Tufts Faculty is making transistors from threads. Not threads of silicon, or quantum threads, or threads as a metaphor for one factor small and high-tech. Actual threads, like for sewing. Actually, there’s lots further involved, like carbon nanotubes — howdy, it was once as soon as each that or graphene, right kind? — gold wires, and one factor referred to as an ionogel that holds all the factor together in a blob of electrolyte. The idea is to remove all rigid portions and make in fact flexible circuits. The chances for wearable sensors could be endless.

And finally, here’s a neat design for an ergonomic device knife. It’s from our friend [Eric Strebel], an business clothier who has been instructing us all such a lot about his field through his YouTube channel. This knife is a minimalist affair, designed for those circumstances when you wish to have more than an X-Acto then again a whole device knife is prohibitively bulky. [Eric’s] design is a simple 3-D-printed clamshell that holds an ordinary device knife blade firmly while providing very good grip as a result of thoughtfully located finger depressions. We always get a kick out of observing [Eric] design little widgets like the ones; there’s a lot to learn from observing his design process.

As a result of [JRD] and [mgsouth] for tips.
