The new version of Eagle is on out! The biggest changes coming are a new design feature and an improved autorouter. We are both veterans of Eagle and PCB board design so this blog is intended as both a review and a tutorial of the new features that Eagle v7 brings. Let’s dive right in.

To make the design process more real, we decided to design a circuit from scratch. A simple circuit that Sophi has worked with is one that uses an audio signal to control a hobby servo, which could be used to control an animatronic. It’s a little early for Halloween, but Sophi had used this circuit before and planed on using it again in October. Many thanks to Scary Terry who gave us permission to use his design.

by cadsoftusa.com:

The award winning EAGLE is a powerful and flexible PCB design software offering high level functionality of expensive commercial circuit board design software at a fraction of the cost for over 20 years. EAGLE offers the three modules: Schematic-Editor, Layout Editor and Autorouter embedded on one single interface. EAGLE is easy to learn, easy to use and easy to buy. It runs on Linux, Mac and Windows and allows feature enhancement, such as simulation, 3D-visualization, data import and export and self defined commands, through User Language Programs (ULP’s) which are partly integrated in EAGLE and available at the download area.

In this post I’ll be going over how to cut out solder stencils for both ExpressPCB and EagleCAD designs on a laser cutter. I recently had a need to create some stencils from both of these programs and spent quite a bit of time at the Dallas Makerspace working with their laser cutter to get the settings just right. I’ll be cutting some designs that are mostly 0603/0805 package sizes, so don’t expect ultra-tight pitch stencils from this technique!

Mentor Graphics, in conjunction with Digikey, has announced the public beta of their $299 Designer Schematic, joining companies like CadSoft (Eagle), RS (DesignSpark), and DipTrace in offering entry-level software in the triple-, double-, or even single-digit price range. Designer Schematic is a scaled-down version of DX Designer, and features integration with Digikey’s massive part inventory.

Ben is always looking for new tools and processes to help with all the projects he builds. He’s got a CNC mill, laser cutter, and a 3-D printer, but hasn’t found a way to whip up a PCB at his shop. He’s hand wired many circuits, but this can be tedious. He’s designed PCBs in Eagle and sent them off for production at a board house, but this doesn’t help when he wants a PCB the same day. In this episode, Ben experiments with three methods of PCB etching and shares the results.

Anyone who has learned a layout package like EAGLE and sent a board off to a fab knows the trepidation felt when submitting the final gerbers. It doesn’t matter if the order is for 3 PCBs or 3,000 PCBs. The time lost from an error can ruin a project’s momentum, especially if it is a boneheaded error.

There is a better way to check all of the footprints with a layout: Paper PCB Protos. This low-tech technique only takes an hour, but can provide 100% confidence in the footprints checked. Thanks to proper scaling of the PCB, it is possible to create a PDF and print out an exact representation of the board. The designer can then place parts on the paper to quickly determine if a component’s footprint will be suitable, at least for a pilot production build.

At Dangerous Prototypes we have a team of amazing PCB designers. We crank out a lot of boards publicly and privately, but even we can’t keep these hungry routing addicts busy all the time. Now we’re lending our routing skills to you for your open hardware project through a new site: Dirty Circuits.

If you have an open hardware project and would like help routing the PCB, we’re here to help.

With Texas Instruments’ WEBENCH Schematic Editor, engineers can customize power-management designs and simulate the circuit created within the WEBENCH environment. According to the company, the new feature reduces design and verification time from hours to minutes. The editing and simulation package maintains a library of over 40,000 components. As a result, it’s possible to incorporate multiple mixed output capacitors, filtering, board parasitics, and snubber circuits into WEBENCH power-supply designs. Then those customized power designs can be simulated (using the WEBENCH Power Designer’s Spice simulator) before they’re exported to CAD development platforms like Cadence OrCAD Capture CIS, Mentor Graphics Xpedition xDX Designer, CADSoft EAGLE, and Altium formats (e.g., Altium Designer). The WEBENCH environment consists of online tools such as Designer and Architect that enable end-to-end analog circuit design.

Creating a solder paste stencil for a toaster reflow oven or hot plate is simple when you have access to a laser cutter. I used the Laser Cutter at my local TechShop to create this and other PCB stencils.

This Instructable assumes you have created a PCB and are able to generate the Gerber Files for it. Specific directions will be given for EAGLE, but other PCB software can be used. The board used in this example is an Arduino RTC Shield based on the DS3231. Follow the link for the EAGLE design files if you want to follow along.
