Creating A PCB In Everything: Upverter

For the last five months, I’ve been writing a series of posts describing how to build a PCB in every piece of software out there. Every post in this series takes a reference schematic and board, and recreates all the elements in a completely new PCB tool.

There are three reasons why this sort of review is valuable. First, each post in this series is effectively a review of a particular tool. Already we’ve done Fritzing (thumbs down), KiCad (thumbs up), Eagle (thumbs up), and Protel Autotrax (interesting from a historical perspective). Secondly, each post in this series is a quick getting started guide for each PCB tool. Since the reference schematic and board are sufficiently complex for 90% of common PCB design tasks, each of these posts is a quick how-to guide for a specific tool. Thirdly, this series of posts serves as a basis of comparison between different tools. For example, you can do anything you want in KiCad and most of what you want in Eagle. Fritzing is terrible, and Autotrax is the digital version of the rub-on traces you bought at Radio Shack in 1987.

With that introduction out of the way, let’s get cranking on Upverter.

A little bit about Upverter

Upverter was founded in 2010 as an entirely web-based EDA tool aimed at students, hobbyists, and Open Hardware circuit designers. This was one of the first completely web-based circuit design tools and Upverter’s relative success has been a bellwether for other completely web-based EDA tools such as circuits.io and EasyEDA.

I would like to take a second to mention Upverter is a Y Combinator company (W11), which virtually guarantees this post will make it to the top of Hacker News. Go fight for imaginary Internet points amongst yourselves.

Upverter is a business after all, so how are they making money? Most EDA suites offer a free, limited version for personal, hobbyist, and ‘maker’ projects, and Upverter is no exception. The professional tier offers a few more features including CAM export, 3D preview, an API, simulation (coming soon), BOM management, and unlimited private projects for $125 per seat per month, or $1200 per seat per year.

To give you a basis of comparison for that subscription fee, Eagle CAD’s new license scheme gives you everything – 999 schematic sheets, 16 layers, and unlimited board area – for $65 per month, or $500 per year. Altium’s CircuitStudio comes in at $1000 for a one-year license. There are more expensive EDA suites such as Altium Designer and OrCAD, but you have to call a sales guy just to get a price.

Upverter is positioning itself as a professional tool at a professional price. There are better tools out there, of course, but there are thousands of businesses out there designing products with tools that cost $500 to $1000 per seat per year. In any event, this is all academic; the Hackaday crowd gravitates towards the free end of the market, whether that means beer or speech.

A big draw for Upverter is their Parts Concierge service. You’ll never have to create a part from scratch again, so the sales copy says. Apparently, Upverter is using a combination of very slick scripts to pull part layouts off a datasheet and human intervention / sanity check to create these parts. Does it work? We’re going to find out in the review below.

Creating A PCB In Everything: Creating A Custom Part In Fritzing

This is the continuation of a series of posts where I create a schematic and PCB in various EDA tools. Already, we’ve looked at Eagle CAD, KiCad, and took a walk down memory lane with one of the first PCB design tools for the IBM PC with Protel Autotrax. One of the more controversial of these tutorials was my post on Fritzing. Fritzing is a terrible tool that you should not use, but before I get to that, I need to back up and explain what this series of posts is all about.

The introduction to this series of posts laid it out pretty bare. For each post in this series, I will take a reference schematic for a small, USB-enabled ATtiny85 development board. I recreate the schematic, recreate the board, and build a new symbol and footprint in each piece of software. That last part — making a new symbol and footprint — is a point of contention for Fritzing users. You cannot create a completely new part in Fritzing. That’s a quote straight from the devs. For a PCB design tool, it’s a baffling decision, and I don’t know if I can call Fritzing a PCB design tool now.

Convert that Cheap Laser Engraver to 100% Open-Source Toolchain

laserweb-on-cheap-laser-squareLaserWeb is open-source laser cutter and engraver software, and [JordsWoodShop] made a video tutorial (embedded below) on how to convert a cheap laser engraver to use it. The laser engraver used in the video is one of those economical acrylic-and-extruded-rail setups with a solid state laser emitter available from a variety of Chinese sellers (protective eyewear and any sort of ventilation or shielding conspicuously not included) but LaserWeb can work with just about any hardware, larger CO2 lasers included.

LaserWeb is important because most laser engravers and cutters have proprietary software. The smaller engravers like the one pictured above use a variety of things, and people experienced with larger CO2 laser cutters may be familiar with a piece of software called LaserCut — a combination CAD program and laser control that is serviceable, but closed (my copy even requires a USB security dongle, eww.)

LaserWeb allows laser engravers and cutters to be more like what most of us expect from our tools: a fully open-source toolchain. For example, to start using LaserWeb on one of those affordable 40 W blue-box Chinese laser cutters the only real hardware change needed is to replace the motion controller with an open source controller like a SmoothieBoard. The rest is just setting up the software and enjoying the added features.

Creating A PCB In Everything: KiCad, Part 3

This is the third and final installment of a series of posts on how to create a PCB in KiCad, and part of an overarching series where I make the same schematic and board in dozens of different software tools. A few weeks ago, we took a look at making a schematic in KiCad, and more recently turned that schematic into a board ready for fabrication.

For our KiCad tutorials, we’ve already done the basics. We know how to create a PCB, make a part from scratch, and turn that into a board. This is the bare minimum to be considered competent with KiCad, but there’s so much more this amazing tool has to offer.

In part three of this KiCad tutorial, we’re going to take a look at turning our board into Gerbers. This will allow us to send the board off to any fab house. We’re going to take a look at DRC, so we can make sure the board will work once we receive it from the fab. We’re also going to take a look at some of the cooler features KiCad has to offer, including push and shove routing (as best as we can with our very minimalist board) and 3D rendering.

Revealed: Homebrew Controller Working in Steam VR

[Florian] has been putting a lot of work into VR controllers that can be used without interfering with a regular mouse + keyboard combination, and his most recent work has opened the door to successfully emulating a Vive VR controller in Steam VR. He uses Arduino-based custom hardware on the hand, a Leap Motion controller, and fuses the data in software.

We’ve seen [Florian]’s work before in successfully combining a Leap Motion with additional hardware sensors. The idea is to compensate for the fact that the Leap Motion sensor is not very good at detecting some types of movement, such as tilting a fist towards or away from yourself — a movement similar to aiming a gun up or down. At the same time, an important goal is for any added hardware to leave fingers and hands free.

Creating A PCB In Everything: KiCad, Part 2

This is the continuation of a series where I create a PCB in every software suite imaginable. Last week, I took a look at KiCad, made the schematic representation for a component, and made a schematic for the standard reference PCB I’ve been using for these tutorials. Now it’s time to take that schematic, assign footprints to parts, and design a circuit board.

Life on Contract: How to Fail at Contracting Regardless of Skill

I believe higher quality learning happens from sharing failure than from sharing stories of success. If you have set your mind to living on contract, I present this cheat sheet of some of the most simple and effective ways to muck it all up that have surprisingly little or nothing to do with your technical skill, knowledge, or even deliverables.

The previous installment of Life on Contract discussed how one might find clients as an engineering contractor or consultant while also taking a bit of time to pull apart the idea of whether life on contract is appropriate as opposed to, for example, bootstrapping a business instead. Assuming you are set on working as a contractor, let’s talk about what happens after you have found a prospective client (or perhaps more likely: after they have found you.)

WARNING: this article features an utter lack of success tips and tricks. Partly because those can be found in any seminar or business self-help book, but mostly because I do not have a foolproof recipe for success, and cheat codes to unlock easy mode still elude me. But I have witnessed (or committed) and reflected on many excellent ways to fail at contracting; or at the very least succeed in not being invited back.

Just because I won’t be sharing success stories doesn’t mean success has no learning value. Got a success story, or a better way to fail? Tell us about it in the comments!
