Fresh hacks every day
[Christian Aurich] wanted to use his Eagle CAD circuit board design in a proper CAD program in order to design enclosures. There are already a few options along these lines, but they didn't quite fit his needs so he developed a script to import Eagle boards into FreeCAD. The script is packaged as a python macro for FreeCAD. In describing the shortcomings of what's already out there [Christian] … [Read more...]
There's a lot of ways to burn up your time when designing PCBs, but renaming components can be one of the most frustrating. [Joe Pinzone] wrote in with his solution to the problem. Instead of hunting for each part on the schematic to change them one at a time, he makes a list of the substitutions and then uses a script to make all the changes in the XML files. He didn't publish a post about his … [Read more...]
[Svofski's] latest hack seeks to do no more than look cool on his desk. We'd say mission accomplished. He doesn't even need anyone around to be proud of the small round CRT display unit he put together. Just having it hum away next to him will be more than enough to keep him going when regular work gets a bit tedious. One of the biggest challenges when working with a cathode ray tube is the … [Read more...]
When working on his quadcopter project [Matt] decided it would be best to build a robust controller for the device. He had never sent off a PCB design for fabrication, but took the plunge and ended up with a compact and reliable PCB on the first try. One of the first things that comes to mind when we hear about quadcopter controllers are the feedback sensors. The accelerometers which are used … [Read more...]
Learning to lay out a printed circuit board takes some time. But after you've churned out a few it's really pretty easy. If you find yourself at that point it may be time to learn about more complicated board fabrication. We think a good primer is this multi-layer PCB layout guide which [Rik te Winkel] recently put together. It's one of the results of his internship experience. One of the major … [Read more...]
Look at it. Just look at it! This board is a lie. It doesn't exist (at least not what's seen in the image here). Instead this is a lifelike rendering made from Eagle CAD files. We've already seen that it is rather easy to pull Eagle CAD files into Google SketchUp thanks to the EagleUp package. You'll get a 3D model that looks quite nice but it's hardly photo-realistic. This process starts … [Read more...]
[Koogar] came up with a useful tool for checking the measurements of your layouts in Eagle CAD. He calls it the Gridrunner; a custom part that adds a 200mm ruler to your design. Tick marks are in 1/10th of a millimeter increments for great accuracy when used with the zoom feature of Eagle. Once you've got the layout just right, delete the ruler from your design and export it for fabrication. … [Read more...]
