Does not the Z-axis on 3-D-printers appear a 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 could be great if it might paintings with the opposite two axes and in reality do one thing attention-grabbing. Which is precisely what is taking place within thebeing explored on the College of Hamburg. Printing proceeds generally up till the tip, when some adjustments to Slic3r permit clean toolpaths to fill within the stairsteps and convey a clean(er) end. It clearly would possibly not paintings for all prints or printers, however it is great to peer the Z-axis in spite of everything pulling its weight.
If you wish to understand how one thing breaks, very best to speak to anyone who appears within damaged stuff for a residing. [Roger Cicala] from LensRentals.com spends numerous time doing simply that, and he has come to. For his cash, the high wrongdoer in digicam and lens breakdowns is side-mounted buttons and jacks. The explanation why is plain while you take into consideration it: parts fastened perpendicular to the power had to function them are topic to a torque. That is an issue when the one factor maintaining the element to the board is a couple of SMD solder pads. He covers any other attention-grabbing failure modes, too, and the entire article is price a learn to be told how to not design a strong product.
Within the apparently neverending quest to construct the sector’s worst Bitcoin mining rig,. It makes use of 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 couple of new on-line mag for folks like us. Dubbed, the web per month ‘zine is a number of contributed tales from hackers, programmers, retrocomputing buffs, and just about any person with one thing to mention. Each and every article is one web page and is formatted alternatively the writer desires to, which ends up in some attention-grabbing layouts. You’ll be able to take a look at the present factor ; they are nonetheless on the lookout for a number of articles for the following factor, so perhaps believe writing up one thing for them – after you place it on , after all.
Tipline stalwart [Qes] tell us about an enchanting construction in semiconductor production. Relatively than targeting making transistors smaller, a group at Tufts College is. No longer threads of silicon, or quantum threads, or threads as a metaphor for one thing small and high-tech. Precise threads, like for stitching. In fact, there is masses extra concerned, like carbon nanotubes — whats up, 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 in reality versatile circuits. The probabilities for wearable sensors may well be never-ending.
And in spite of everything, here is a neat design for an ergonomic software knife. It is from our buddy [Eric Strebel], an commercial dressmaker who has been educating 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 software knife is prohibitively cumbersome. [Eric’s] design is a straightforward 3-D-printed clamshell that holds a normal software knife blade firmly whilst offering excellent grip because of thoughtfully situated 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.
Because of [JRD] and [mgsouth] for guidelines.
