VideoOverlayShield is now Creative Commons Attribution-ShareAlike

We’ve decide to update the license on the VideoOverlayShield product. Previously it was licensed under the Creative Commons Attribution-Noncommercial-Share Alike, which says you can copy and remix the product but not for commercial purposes.

We have decided that this is no longer necessary and have changed the license of the VideoOverlayShield to the Creative Commons Attribution-ShareAlike 3.0 Unported License. This allows the copy and remix of the product even for commercial purposes. This also puts the product more in line with the values of the Open Source Hardware (OSHW) Definition.

Slides from my presentation on gEDA

Last year I did a presentation on getting started with gEDA at the 2010 Open Source Bridge conference. I just received an email from someone asking for the slides from that presentation. I thought why not post them for everyone.

I don’t have complete presentation notes but you can view the speaker notes I did make from the action menu at the bottom of the full screen presentation.

Join me tonight at the March PLUG Advanced Topics meeting

I’ll be speaking tonight at the Portland Linux/Unix Group advanced topics meeting. The topic is going to be creating a printed circuit board using the gEDA suite of electronic design automation tools.

Here is the announcement from the PLUG mailing list:

The meeting is at 7PM tonight (Tuesday), March 15th at Free Geek: 1731 SE 10TH AVE, Portland, OR.

Hope to see you there.

Arduino shield board outline in gEDA format

I have been working on a few different shield boards for the Arduino platform. In an attempt to make life easier for myself I created a couple starter files for my future projects. The zip file below includes a schematic and PCB file in gEDA format. The board has the four headers and mounting holes for an Arduino shield board. I’ve decided to release the files into the wild for anyone to use.

Low Voltage Labs now has a wiki at

I plan to use the wiki for product documentation, future product ideas, and listing resources related to electronics. Let me know what you think.
