Dots on Schematics

Jun 11 2012, 4:00 PM PDT · 4 comments »

CircuitLab schematics now include connection dots to show when wires intersect. This behavior makes it more clear where components are connected or not, especially in busy schematics, and it's been a highly requested feature on our forums. These dots appear when 3 or more lines (wires or component terminals) intersect at a single point:

In the 15 weeks since we first launched CircuitLab, our users have saved more than 16,000+ circuits in our system. Stay tuned for a blog post about how we used 64 CPUs to re-render them all with our new rendering engine (including connection dots, plus publication-quality schematics).

Publication-Quality Schematics (PDF, PNG, EPS...)

Today we're pleased to release our new rendering backend, providing publication and presentation-quality schematic images in a variety of formats. For printing, we now provide true vector PDFs which look sharp on paper and on-screen. For presentation or inclusion in documents (such as when using Microsoft Office, OpenOffice / LibreOffice, or Google Docs), we offer PNGs at any size. For publication, we provide EPS files to insert into LaTeX, TeXmacs, or similar typesetting systems. And for the web, we provide SVG files that look sharp at any size.

All of these options can be found by clicking the arrow next to the new "Print/Export" dropdown menu on a circuit page:

Some example schematic exports from the NerdKits Sous Vide Controller can be found here: PDF, PNG, EPS, SVG.

We hope you find that CircuitLab is now the easiest way to produce schematic images for reports, presentations, publications, and sharing!

Unlisted Circuits: Easier Sharing of Schematics

Jun 07 2012, 10:45 AM PDT · 1 comment »

We previously provided two simple access control modes for circuits saved in CircuitLab: private and public. And while we have a growing library of public circuits, our statistics still indicate that the overwhelming majority of circuits saved are being kept private. However, we've heard from our users that a more fine-grained ability to share a circuit and simulation -- without sharing it with the entire world -- was needed. As requested on our forums, we've now released an "Unlisted" access control mode.

Unlisted means that anyone with the URL to your circuit can access and open it, and can save a copy for themselves with any changes they make. However, the circuit remains otherwise unlisted on the CircuitLab website, and doesn't show in the activity feeds around the site, your CircuitLab user profile, or via the browse public circuits interface. This means you can easily share an unlisted circuit with your collaborators by simply sharing the URL via e-mail, IM, or your own website. The recipients of your link don't even need to have a CircuitLab account in order to view your schematic and run any simulations.

We've added an access control selection on the circuit page. Just click the little triangle next to the "Make public" or "Make private" button to show the full set of privacy options:

Please let us know how you use CircuitLab to collaborate with your co-workers, classmates, and fellow hobbyists.
