How To Get Involved

There are many ways to contribute to the DorkbotPDX community. Some of us are information junkies, so we have adopted a wealth of ways to share between ourselves and any passersby. Here are a variety of things you can do if you are interested in being a part of this crowd (we are most definitely non-exclusive!):

  • Present on something interesting you're doing/working on/interested in at an upcoming meeting! Let Thomas or Jason know if you have some ideas.
  • Sign up for the mailing lists.
  • Join us on IRC.
  • Sign up on this site and create a member page.
  • Join the DorkbotPDX Flickr group and post pictures you think we should see. The last five of these will appear in the righthand sidebar of the site.
  • Tag your del.icio.us posts with "dorkbotpdx" if you'd like others in the group to see them. You'll notice that these links appear in the low part of the sidebar of the site just like the Flickr pics.
  • Sign up for our Vimeo group and share your Dorkbot videos.
  • Best of all: join us at our bi-weekly meetings.
  • If there's some other way you'd like to get involved or you'd like to make DorkbotPDX aware of something you're working on, feel free to contact us via any of these means.

One final note: please post comments where they are appropriate. If you just have general communication for the group, please post to the mailing list or join the IRC channel.

   Looking for help testing / troubleshooting a project I've been working on; it's a CNC machine I built from a kit (http://www.mydiycnc.com).  It's assembled and wired, but doesn't respond properly when connected to a PC (via parallel port).  Either I've mis-wired it, or something is defective...

   Help me get this working, and I may be able to make some custom parts for you!  e.g. circuit boards - see video of the same machine in action here: http://www.youtube.com/watch?v=GmqRq4SNpeY

   The circuitry consists of three controller boards (each running to a stepper motor for X/Y/Z axes); nothing too complicated, but I don't have the background to figure out why it's behaving the way it is...

Located information and simple way of making you project possible with the materials you have limited your self to.


http://www.youtube.com/watch?v=VqdcU9ULAlA  Shows you how to make a simple real simple tune able Capacitor to improve you system. This I also believe fits in you needed paremeters.


 


And this site by using two diodes will give you a little more power to drive a "Speaker" Don't used a transfomer wind a speaker like was discussed in the meeting using you ohm meter to get the resistance needed ( less loss ) and use a large flat diaphram to create the sound cone http://hibp.ecse.rpi.edu/~john/xtal.html ( concept and instructions to increase power without amp here)


Good Luck
