Does not the Z-axis on Three-D-printers appear a little bit – underused? I imply, all it does is creep up a fragment of a millimeter because the printer works thru each and every slice. It will be great if it will paintings with the opposite two axes and in reality do one thing fascinating. Which is precisely what is going down within the nonplanar Three-D-printing strategies being explored on the College of Hamburg. Printing proceeds most often up till the top, when some changes to Slic3r permit clean toolpaths to fill within the stairsteps and bring a clean(er) end. It clearly may not paintings for all prints or printers, however it is great to look the Z-axis after all pulling its weight.

If you wish to know the way one thing breaks, perfect to speak to any individual who seems to be inside of damaged stuff for a dwelling. [Roger Cicala] from spends a large number of time doing simply that, and he has come to some fascinating conclusions about how electronics equipment breaks. For his cash, the high wrongdoer in digicam and lens breakdowns is side-mounted buttons and jacks. The explanation why is apparent if you consider it: parts fixed perpendicular to the drive had to function them are matter to a torque. That is an issue when the one factor retaining the part to the board is a couple of SMD solder pads. He covers any other fascinating failure modes, too, and the entire article is value a learn to be told how to not design a powerful product.

Within the reputedly neverending quest to construct the arena’s worst Bitcoin mining rig, behold the 8BitCoin. It makes use of the 6502 processor in an Apple ][ to accomplish the essential hashes, and it took somewhat of doing to port the 32-bit SHA256 routines to an 8-bit platform. However therein lies the hack. However what about efficiency? One thing one thing warmth loss of life of the universe…

Contributing Editor [Tom Nardi] dropped a tip a few new on-line mag for folks like us. Dubbed Paged Out!, the net per thirty days ‘zine is a selection of contributed tales from hackers, programmers, retrocomputing buffs, and just about somebody with one thing to mention. Each and every article is one web page and is formatted on the other hand the creator needs to, which results in some fascinating layouts. You’ll be able to take a look at the present factor right here; they are nonetheless in search of a host of articles for the following factor, so possibly believe writing up one thing for them – after you set it on, in fact.

Tipline stalwart [Qes] tell us about a fascinating building in semiconductor production. Quite than targeting making transistors smaller, a crew at Tufts College is making transistors from threads. No longer threads of silicon, or quantum threads, or threads as a metaphor for one thing small and high-tech. Exact threads, like for stitching. In fact, there is masses extra concerned, like carbon nanotubes — hi there, it was once both that or graphene, proper? — gold wires, and one thing known as an ionogel that holds the entire thing in combination in a blob of electrolyte. The theory is to take away all inflexible parts and make really versatile circuits. The probabilities for wearable sensors might be never-ending.

And after all, here is a neat design for an ergonomic application knife. It is from our good friend [Eric Strebel], an commercial dressmaker who has been instructing us all so much about his box thru his YouTube channel. This knife is a minimalist affair, designed for the ones instances when you want greater than an X-Acto however a complete application knife is prohibitively cumbersome. [Eric’s] design is a straightforward Three-D-printed clamshell that holds an ordinary application knife blade firmly whilst offering excellent grip because of thoughtfully located finger depressions. We all the time get a kick out of staring at [Eric] design little widgets like those; there is a lot to be told from staring at his design procedure.
