If you need to know the exact length of a trace in Eagle — for differential signals, for example, or if you have a high-speed data bus like on SDRAM and you’re not using a buffer so you need to make sure all the traces are the same length, and make sure they’re no too long for the strict timing constraints, etc. — Eagle has a nice little ULP script that will display some basic information on every trace on your PCB, including the maximum theoretical current you can draw through the traces, etc. Just type “run length-freq-ri” in the command window of the PCB view and you should get the displayed info above! (Note that by default this ULP assumes 1oz/0.035mm copper, though this is the most common anyway.)

Cameron tipped us to a circuit simulator for Android devices. It looks a lot like the java based circuit simulator we wrote about a few weeks ago.  Everycircuit seems like a useful tool if you want to play around with electronics anywhere you find yourself. Unfortunately it seems to only support abstract level simulation models, not actual real components.

Component Organizer is a small and easy to use program that lets you search for components, datasheets and application notes in a very easy and practical way.

Ideal to use in a PEN drive, so you could always have all the important data with you. Get Component Organizer and take it for a spin to see what it can actually do for you!

EagleUp is a new way to render Eagle PCBs in 3D. It integrates with Google Sketchup so it’s possible to design cases around the PCB model:

version 4 has been released. Most of the import and export procedures have been automatized to simplify the process, so that you can focus in design, and not in the conversion 2D/3D.

With the version 4, you export from Eagle in 2 clicks, and import into sketchup in 3 clicks. No more tiring image creation and manual import necessary. Give it a try !

Eagle 3D is another way to make 3D board renderings, and it works for non-Windows users too. [via]

Don’t we all have had frustrations galore when we were trying to fine tune the resistor divider for our voltage feedback on PS and LODs? Well, my good friend Art Nace came up with this wonderful tool to calculate the best fit values for the resistors for dividers. It even lets you specify voltage tolerances over temp. give it a try and let me know what you think?

Want a graph of data you’re collecting, or a cool GUI interface for a project? Micset XEdit wants to do that:

XEdit Project Editor is Integrated development environment to configure, develop and manage [supervisory control and data acquisition] applications.  XEdit Project Editor is used to create projects, multiproject, configure devices, tags/points, alarms, users, events, server-side scripts and others

It lets you make cool GUI to control a microcontroller project, or display sensor data. No word on the license though.[via]
