MakerGear Mendel Prusa Started


I got this Mendel Prusa RepRap kit from MakerGear a month ago but I just finally started working on it last night. I’m going to try to get it working before Heart Rhythm so I can hand out little printed heart models.

The Heart Rhythm Podcast Without iTunes

The Heart Rhythm Society has an interesting podcast, wherein the author of an article in each issue is interviewed, often by Dr. Doug Zipes. I tried to sign up for it here, but it only gives directions for subscribing with iTunes. I don’t care for iTunes these days, so I went about finding the real RSS feed for the podcast.

If you want it, here it is:

Hopefully the webmaster at HRS will wise up and post this link as well. Enjoy!

Using a bluetooth headset with SIP on Linux

After hours of banging my head against the wall, I have finally got my bluetooth headset working with my SIP accounts in Ubuntu Linux 10.04 LTS (Lucid Lynx).

Assuming bluetooth is already working, and you’ve paired your headsets, do the following things:

1. Download the x-lite 4.0 software for Linux
2. Run the softphone with ‘padsp xtensoftphone’ (this will wrap it’s audio i/o with pulseaudio
3. Change the audio settings in the x-lite phone to use the PulseAudio virtual device
4. Make sounds in the x-lite phone, call an 800 number or something, then while sound is being made run ‘pavucontrol’
5. In the output and recording tabs, find the padsp streams and select the bluetooth headset inputs/outputs.

Caveats: I haven’t tested whether this is remembered between logins, and I think if you are using padsp to wrap other applications this will send them all through bluetooth.

Let me know if this helps you or if you get stuck!
