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!
Archiving Emails and Attachments to PDF from Thunderbird in Linux
I have a couple of businesses, plus my own personal transactions, and every year come January I have to make sure I have all of the appropriate financial documentation for them, including copies of invoices and receipts. Fortunately, most of my invoices and receipts are now in email form, though I still get some paper ones (which go straight into the ScanSnap). Unfortunately, emails and attachments can’t go nicely in a reference folder in my Dropbox.
Thunderbird to the rescue!
I use Mozilla Thunderbird for my email for mostly the same reason I still use FireFox to browse the web: there’s a plugin for almost anything I want to do. Also, in Linux it’s easy to use a CUPS-PDF virtual printer to print to PDF. Combining this with the attachment extractor Thunderbird plugin allows me to dump all of the attachments and emails to files on my hard drive in just a few clicks.
I have ‘Invoices’ and ‘Receipts’ email folders that need to be dumped, so I just go into each folder, select all messages, print them using CUPS-PDF, and then right-click and tell AttachmentExtractor to dump any attachments as well. Done, in about 5 minutes. Trying to do this manually would take countless hours, meaning in reality that I would just never do it, and if my taxes were audited, it would be a total nightmare.
Hopefully if you have this same problem google + this post will help you out. Enjoy!
Power Supply Mounting Bracket – Found
I had to buy a new power supply for an old case recently, but when I went to install it, I realized that it was smaller than the previous one. I was able to mount it on one side with two screws, but it wasn’t really stable.
It took a phone call to Antec to find what I needed, and even knowing what’s on the page, I can’t find it with Google, so here it is:
Antec Power Supply Mounting Bracket
Hopefully that’ll save someone else the trouble I went through.
ADDENDUM: The commentor is correct. It has been moved. If you call Antec and find the new location please post it here.
