The largest change in the announcement is the removal of Upverter’s paid professional tier of service. Now, the entirety of Upverter is free. Previously, this paid professional tier included CAM export, 3D preview, BOM management, and unlimited private projects for $1200 per seat per year.
Hackaday has taken a look at Upverter before in an book-length series of posts describing how to build a PCB in every software tool. While Upverter is a web-based PCB design tool that doesn’t respond to a right mouse click, the experience was pleasant overall. There are some interesting features in Upverter that make PCB design work fun — snap-to alignment of pads, a phenomenal number of ways to export your data — and it’s more than capable enough for the electronics hobbyist.
With the Altium announcement, [Zak] says Upverter will continue on its mission to create a system to design a complete product, from schematic to enclosure to firmware to BOM management.
The [BBC] is reporting that driverless semi-trailer trucks or as we call them in the UK driverless Lorries are to be tested on UK roads. A contract has been awarded to the Transport Research Laboratory (TRL) for the trials. Initially the technology will be tested on closed tracks, but these trials are expected to move to major roads by the end of 2018.
All of these Lorries will be manned and driven in formation of up to three lorries in single file. The lead vehicle will connect to the others wirelessly and control their braking and acceleration. Human drivers will still be present to steer the following lorries in the convoy.
This automation will allow the trucks to drive very close together, reducing drag for the following vehicles to improve fuel efficiency.”Platooning” as they call these convoys has been tested in a number of countries around the world, including the US, Germany, and Japan.
Are these actually autonomous vehicles? This question is folly when looking toward the future of “self-driving”. The transition to robot vehicles will not happen in the blink of an eye, even if the technological barriers were all suddenly solved. That’s because it’s untenable for human drivers to suddenly be on the road with vehicles that don’t have a human brain behind the wheel. These changes will happen incrementally. The lorry tests are akin to networked cruise control. But we can see a path that will add in lane drift warnings, steering correction, and more incremental automation until only the lead vehicle has a person behind the wheel.
There is a lot of interest in the self driving industry right now from the self driving potato to autonomous delivery. We’d love to hear your vision of how automated delivery will sneak its way into our everyday lives. Tell us what you think in the comments below.
There was a third-party multiplayer upgrade pack for one of the Quake games back in the ’90s that included a whole slew of non-standard weapons. Among them one of the most memorable was a gravity well, that when thrown into the middle of a crowded room full of warring players would suck them into a vortex. Assuming its user had made it to safety in time, they would then be left the victor. The hyper-violent make-believe world of a first-person shooter is probably best left in a Pentium server from the ’90s, with few direct parallels in the real world. Maybe laser tag, or Nerf battles, are the closest you’ll get.
If you are a Nerf enthusiast, then you’ll appreciate [Giaco Whatever]’s CO2-powered remote-control Nerf bomb as an analogue of that Quake gravity well. It fires twelve darts at the press of a button on an infra-red remote control. The firing tubes sit in a nicely machined manifold connected via a solenoid valve to a little CO2 gas bottle. In the hectic world of a Nerf war it is slid out into the field of combat, its operator takes cover, and the other participants are showered in foam darts. There are probably kids who would sell their grandparents to own this device.
The build is detailed in the video below the break, along with a wonderfully tongue-in-cheek movie segment demonstrating it in action.
We’ve always been fascinated at the number of ways logic gates can spring into being. Sure, we think of logic gates carrying electrons, but there are so many other mechanical means to do the same thing. Another method that sometimes has a practical use is fluidic or pneumatic logic. We guess [dAcid] has a similar interest since he’s written two posts on how to construct the gates. One post covers making them with ordinary tools. The other requires an SLA printer.
According to [dAcid], the design is effectively the same either way, but the SLA printing is more precise. Silicone is an important component, either way. Fluidic logic has applications in some mechanical systems, although digital logic has made it less important than it once was. However, it is very possible that nanotechnology systems will implement logic mechanically, so this is still an interesting technique to understand. You can see videos of how a D latch looks using both methods, below.
If you are an American, you’ll probably now find yourself in one of three camps. People who are going to see the upcoming solar eclipse that will traverse your continent, people who aren’t going to see the eclipse, and people who wish everyone would just stop going on incessantly about the damn eclipse.
Whichever of those groups you are in though, there is an interesting project that you can be a part of, an effort from the University of Massachusetts Boston to crowdsource scientific observation of the effect a solar eclipse will have on the upper atmosphere, and in particular upon the propagation of low-frequency radio waves. To do this they have been encouraging participants to build their own simple receiver and antenna, and make a series of recordings of the WWVB time signal station before, during, and after the eclipse traverse.
This is an interesting and unusual take upon participation in the eclipse, and has the potential to advance the understanding of atmospheric science. It would be fascinating to also look at the effect of the eclipse on WSPR contacts, though obviously those occur in amateur bands at higher frequencies.
If you are an EclipseMob participant, we’d love to hear from you in the comments. Does your receiver perform well?
If you have a shortwave receiver, tune it to 4625 kHz. You’ll hear something that on the surface sounds strange, but the reality is even stranger still. According to the BBC, the radio station broadcasts from two locations inside Russia — and has since 1982 — but no one claims ownership of the station, known as MDZhB. According to the BBC:
[For 35 years, MDZhB] has been broadcasting a dull, monotonous tone. Every few seconds it’s joined by a second sound, like some ghostly ship sounding its foghorn. Then the drone continues.
Once or twice a week, a man or woman will read out some words in Russian, such as “dinghy” or “farming specialist”. And that’s it.
If you don’t have a shortwave handy, you can always try one of the many web-based software defined radios. Search for 4.6 MHz, and pick a location that should have propagation to Russia and you are all set.
The latest release of EAGLE builds a bridge between mechanical design and electronic design. Version 8.3 rolls in the ability to synchronize between EAGLE and Fusion 360. You can now jump between mechanical design and PCB layout without the need for extra steps in between. This is the first release of EAGLE that highlights what the Autodesk purchase actually means.
Just over a year ago, Autodesk bought EagleCAD which is one of the more popular PCB design suites for students, electronic hobbyists, and Open Hardware engineers. While there were some questions about the new license structure of EAGLE under the Autodesk banner, there was a promise of a faster development schedule and the possibility for integration of EAGLE with Autodesk’s CAD programs. Now it’s finally time for EAGLE and Fusion 360 to become besties.
The EAGLE and Fusion 360 integration update includes an online library editor with managed libraries. These online libraries are the ‘cloud’ solution to a folder full of custom EAGLE libraries filled with parts. These libraries package 3D models with the EAGLE libraries, simplifying mechanical design. You can place components on your PCB, then pull that layout into Fusion 360 to see how the board will work with your enclosure. Component placements that collide with the enclosure can be adjusted in Fusion before jumping back to EAGLE to fix the routing.
Embedded passive designs. The resistors *are* the PCB.
There are a few other interesting items in the release notes for EAGLE 8.3. At the top of the list is a new ‘board shape’ object. This is more than just a milling layer for a board outline — the board shape object can now be checked with DRC to ensure components aren’t too close to an edge. This also allows for new features like customizable cutouts and embedded passive designs, or putting resistors and caps in the layers of a PCB instead of placing them as discrete components.
With this release, there is a new Single Layer Mode. This mode only highlights the active layer of the PCB, leaving all other layers grayed out. To be honest, this feature should have been in EAGLE ten years ago, but late is better than never.
For the last year, those of us not complaining about the new EAGLE licensing situation have been watching the updates to EAGLE creep out of Autodesk. There has been a lot of speculation on what Autodesk would bring to the table when it comes to electronic design. This is it. It looks like Autodesk is fulfilling their promise to integrate electronic and mechanical design. The latest EAGLE release looks great, especially with the addition of walk-around routing and something resembling push and shove traces added earlier this year, combined with this update for the mechanical side of design projects.
