William Anders, astronaut who took the famous ‘Earthrise’ photo, dies at 90William A. Anders, the astronaut behind perhaps the single most iconic photo of our planet, has died at the age of 90. On Friday morning, Anders was piloting a small plane that dove into the water near Roche Harbor, Wash. His son Greg confirmed his death. Anders retired from the Air Force Reserve as a […]

And if you think you’re free of them because you have an AMD chip, that’s just Intel’s instruction set with a different badge on the silicon. At least AMD licenses it, though — in the 80s there was another game in town that didn’t exactly ask for permission before implementing, and improving upon, the Intel chips available at the time.
The NEC V20 CPU was a chip that was a drop-in replacement for the Intel 8088 and made some performance improvements to it as well. Even though the 186 and 286 were available at the time of its release, this was an era before planned obsolescence as a business model was king so there were plenty of 8088 systems still working and relevant that could take advantage of this upgrade. In fact, the V20 was able to implement some of the improved instructions from these more modern chips. And this wasn’t an expensive upgrade either, with kits starting around $16 at the time which is about $50 today, adjusting for inflation.
This deep dive into the V20 isn’t limited to a history lesson and technological discussion, though. There’s also a project based on Arduino which makes use of the 8088 with some upgrades to support the NEC V20 and a test suite for a V20 emulator as well.
If you had an original IBM with one of these chips, though, things weren’t all smooth sailing for this straightforward upgrade at the time. A years-long legal battle ensued over the contents of the V20 microcode and whether or not it constituted copyright infringement. Intel was able to drag the process out long enough that by the time the lawsuit settled, the chips were relatively obsolete, leaving the NEC V20 to sit firmly in retrocomputing (and legal) history.Can a Toy Printer Be Made Great?Now that the bottom end of the 3D printer market has been largely cleared of those garbage “Prusa i3 clone” models which used to infest it a few years ago, a new breed of ultra-cheap printer has taken their place. EasyThreed make a range of very small printers pitched as toys, and while they’re no great shakes by the standards of most Hackaday readers, they do at least work out of the box. For their roughly $75 price tag they deliver what you’d expect, but can such a basic machine be improved with a few upgrades? [Made with Layers] has taken a look.
These printers have an all-plastic snap-together construction with a 10 cm by 10 cm bed and a set of small geared stepper motors driving their axes. He concentrates on stiffening the structure, upgrading those motors, and because he’s sponsored by a 3D printer electronics company, upgrading their controller.
The motors were replaced first with some NEMA 11 steppers, and then by some over-sized ones which maybe push the idea a little far. By moving the motors to a bracket he was able to free up their mountings to secure a 3D printed insert to stiffen the arms. Perhaps he’s pushing it a little for the video with the electronics upgrade, but we think there’s a happy medium with the smaller of the two motor upgrades and the stiffening.
So if you have an EasyThreed in your life it’s possible to upgrade it into something a little better, but it’s worth asking whether that $75 might be better spent in saving for a better machine in the first place. We’ve been curious about these tiny printers for a while though, and it’s interesting to have some more of our questions answered.AJ Releases FREE Qsynthi Quantum Synthesizer Plugin

However these creations aren’t perfect, particularly when it comes to the adhesion between their layers. Aside from structural failures along the layer lines there is also the question of those joins being permeable, limiting the possibility for waterproof or gas proof prints. It’s something [German Engineer] has tackled in a new video, in which he’s looking at the design and preparation of small propane tanks.
This is the frame at which the 3D printed tank explodes
The attraction of propane as a fuel is that it liquefies easily on compression, so a propane cylinder or tank will be an equilibrium of liquid propane with pressurized gas above it, whose pressure depends on the ambient temperature. This means that any tank must be expected to have a working pressure somewhere between 150 and 200 PSI, with of course a design pressure far exceeding that for safety reasons.
Filling a 3D printed tank immediately results in the propane escaping, as he demonstrates by putting one of his prints under water. He solves this with a sealant, Diamant Dichtol, which is intended to polymerize in the gaps between layers and create a gas-tight tank. A range of three tanks of different thicknesses are treated this way, and while the 1 mm thick variety bursts, the thicker ones survive.
It’s clear that this technique successfully creates gas-tight prints, and we can see the attraction of a small and lightweight fuel tank. But we can’t help worrying slightly about the safety, for even when the material is a lightweight 3D print, high pressure equipment is not to be trifled with. Tanks do burst, and when that happens anyone unfortunate enough to be close by sustains nasty, even life-threatening injuries. Use the technique, but maybe don’t hit it with high pressures.UniMagic effects plug-in from Rob Papen Rob Papen's latest plug-in is an incredibly simple processor that has been designed to offer a quick and easy way to ‘thicken up’ just about any sound source.

Reverse Engineering Keeps Early Ford EVs RollingWith all the EV hype in the air, you’d be forgiven for thinking electric vehicles are something new. But of course, EVs go way, way back, to the early 19th century by some reckonings. More recently but still pretty old-school were Ford’s Think line of NEVs, or neighborhood electric vehicles. These were commercially available in the early 2000s, and something like 7,200 of the slightly souped-up golf carts made it into retirement communities and gated neighborhoods.
But as Think aficionado [Hagan Walker] relates, the Achille’s heel of these quirky EVs was its instrument cluster, which had a nasty habit of going bad and taking the whole vehicle down with it, sometimes in flames. So he undertook the effort of completely reverse engineering the original cluster, with the goal of building a plug-in replacement.
The reverse engineering effort itself is pretty interesting, and worth a watch. The microcontroller seems to be the primary point of failure on the cluster, probably getting fried by some stray transients. Luckily, the microcontroller is still available, and swapping it out is pretty easy thanks to chunky early-2000s SMD components. Programming the MCU, however, is a little tricky. [Hagan] extracted the code from a working cluster and created a hex file, making it easy to flash the new MCU. He has a bunch of other videos, too, covering everything from basic diagnostics to lithium battery swaps for the original golf cart batteries that powered the vehicle.
True, there weren’t many of these EVs made, and fewer still are on the road today. But they’re not without their charm, and keeping the ones that are still around from becoming lawn ornaments — or worse — seems like a noble effort.
