The Diffusion science show has been cut by 2SER, to make room for new
shows by new volunteers.

After 19 years on air, and 15 years of contributions from me, it was the
final Diffusion Science Radio broadcast from 2SER last night.
Now you will only be able to hear the show by subscribing to the
podcast
at www.diffusionradio.com, listening on one of the 14 stations
on the Community Radio Network that broadcast us around Australia, on
the National Science Foundation's Science360 internet radio station in
the USA, and on Astronomy.FM in the UK.

Diffusion has 700 weekly subscribers to the podcast, with 10 000
downloads every month.

Its the end of an era of funny, quirky, weird and wonderful science that
started in 1995. Over 50 volunteers have broadcast more than 180
interviews as captured by the podcast at www.diffusionradio.com, along
with well researched reports, panel discussions, book reviews, science
songs, trivia games and radio plays.

Diffusion has been an institution where volunteers were trained by
fellow volunteers to do all the jobs of producing a radio show, from
operating the panel, conducting interviews, presenting, script writing,
editing and producing.

In 2005 the Discovery show was asked by a cable Science network to
change its name, due to similarities.

In 2011 astronomer Matt Dawson named a planetoid "VictoriaBond". The
Minor Planet Ephemeris Service says:
"Victoria Bond is the name of the popular Australian science show
presenter of "Diffusion Science Radio". Her catchphrase "Planetoid! I
love that word!" and accurate astronomy coverage have endeared her to
listeners worldwide". Ironically, the voice saying the phrase in our
theme music actually belongs to Jacqui Hayes.

Later in 2011, Diffusion won the 2SER Best Talk Show award.

Then in 2012 Diffusion was granted $10 000 for content development from
the Community Broadcasting Foundation.

Here's the final 2SER broadcast, complete with a compilation of our different show themes over 15 years.

I'm now looking to find funding for professional recording gear, courses in marketing my journalism, while singing the words to Jonathan Coulton's "Still Alive".
Diffusion won!

I went to the Red Cross Blood Service in Alexandria, where all the blood donations are sorted and tested before being passed along to hospitals to speak to with Joe Patkes.

Joe Patkes, is Red blood cell serology manager for the Red Cross blood service for NSW. He's had 22 years experience in the blood transfusion business, 7 years with the Australian Red Cross, and before that, 14 years in the United States. He spoke with me about blood types and transfusions. Please excuse the occasional buzzing from the machines in the background.

As I wrote earlier, Heliotropium foertherianum or Octopus Bush is a traditional remedy for Ciguatera Fish Poisoning that was scientifically tested in assays last year as effective against the toxin. While it hasn't been through the clinical trials that would show that it was definitely effective, as a native Australian plant its listed as bush tucker, so its not toxic.

Given that its not toxic, I've discussed this with my doctor, and I'd like to try the remedy of Octopus bush leaves boiled up as a tea. I am concerned about what will happen in my body if the toxin is dislodged as described in the paper, but its the only treatment on offer. The researchers in France are interested that the active compound in Octopus bush is similar to rosmarinic acid which they know how to make, so they've patented the use of rosmarinic acid for treating Ciguatera Fish Poisoning. I'd like to interview them, I hope they speak English.

A fellow CFP sufferer on facebook is trying rosmarinic acid supplements that are extracted from Rosemary, because its available. My problem is that the amounts of rosmarinic acid in the supplements are tiny. I'm after a medically active dose.

So I'm looking for sources of Octopus Bush itself, as I'd rather try the remedy that was proved to work. In the best of all possible worlds I'd wait for the clinical trials to be initiated, funded and completed, and for all the medicinal interactions to be mapped. However I've been sick ten years, and I'm recovering from a really vicious relapse that's lasted 12 months.

I can't find any sales of this plant or its extracts after exhaustive searches, so I've written to the Royal Botannical Gardens and the CSIRO for help. They've directed me to the Australian Tropical Herbarium, and the Northern Territory Herbarium . I'll send my request, and keep eating the rosemary.

Mark Changizi's "The Vision REvolution" is about the latest research into the way humans see the world. Mark uses the metaphor of super-powers to entertainingly communicate how we see, and how our ancestors saw, and the special abilities we possess but take for granted, such as X-ray vision, and colour empathy.

Professor Thomas Borody of the Center for Digestive Diseases is researching which illnesses are caused by the bacteria in the bowel going wrong, and developing bacterial therapies to restore health. In 1999 I spoke to him about how bowel flora affects the brain, and the triple-S, sick flora syndrome.

Since that time research around the world has started to catch up, and for one illness at least, clostridium difficile infection, this poo transplant will become the standard treatment. Other illnesses may follow.

A traditional herbal medicine based on the Octopus bush has been found effective against Ciguatera fish poisoning in bioassay tests. The active ingredient Rosmarinic acid has been patented. Clinical trials are yet to be done, but its the most hopeful news for Ciguatera Fish Poisoning sufferers I've seen in the ten years I've been poisoned. The active ingredient actually seems to work against the action of ciguatoxins and also act to remove them from the body.

At the Open Source Developer's Conference 2012, Gavin Smith gave a talk "How to make anything. Or: Robots, Paint, and Lasers". Gavin is from Robots and Dinosaurs, the Sydney Hackerspace http://robodino.org, where he can make anything using 3D printing, laser CNC and electronics.

This video was shot on my Looxcie Point Of View camera, mounted on my left ear. The advantage is that my head moves the camera. The disadvantage is that my head moves the camera. I tried the camera stabilisation on youtube, and it seemed wrong. Let me know if you can think of ways to improve the quality. The link up the top is to an OGV 100megabyte video file. The original MP4 is available on the Internet Archive but its over 400 Megabytes. Email me or leave a comment if you'd like the link.

I need that Arduino inventor kit, along with a 3D Printer, and to be able to make those amazing laser cut wooden boxes.
Below is the video Gavin showed of "My little piece of privacy"

At the MooresCloud product launch, inventor Mark Pesce spared 10 minutes in the stairwell to talk about his networked lamp platform.  MooresCloud, is a playful lamp with a LAMP stack, which means it runs Linux, Apache web server, MySQL database and Python or Perl programming language -L.A.M.P. - it can talk to other networked things.

This is my first interview using my POV wearable Looxcie camera, and my apologies, but it wobbled a lot. I'm also new to video editing on linux, so I used Openshot until it failed, and then exported video to avidemux to edit the final version. Unfortunately I lost quality in the process. I'll put up a better edited version later. For future videos I'm looking at mounting the camera on my glasses instead of on my ear. It should wobble much less.

Today I did a firmware update for my twin tuner DTV2000DS TV card, and was soon prompted for the latest Ubuntu 12.04LTS kernel firmware update. I updated, and rebooted. Now all my tuners work! MythTV sees 4 tuners, and Kaffeine sees 3 tuners. A test recording on MythTV was weirdly slow and wrong, so I might stay with Kaffeine for now.
Three TV tuners working, I just have to wait for something worth recording like Derren Brown Investigates next week on SBS1.


I bought a Leadtek Winfast DTV2000DS twin TV tuner DVB-T PCI card for $55 in August 2011, in order to make my desktop a Digital Video Recorder, or DVR. I'd researched online that it was supported by Ubuntu, and PCI seemed safer than USB. I figured a USB dongle could be knocked as it sticks out, whereas PCI is safely inside the case.

The LeadTek Winfast DTV2000DS twin tuner has the af9015 chipset, and worked really well.

MythTV is an all-singing, all-dancing, super-duper TV recording and playback centre, which has a backend that runs all the time, ready to record. It also has a frontend that only runs when you want to record stuff, or play video. Its supposedly like a free TiVo.

I followed the tutorials, and I made it work. The test was to run VLC, open a channels.conf file which had TV station frequencies for Sydney, and see TV show up on my PC. Then I just had to install MythTV, which was again, just following an online tutorial.

Then, after 2 weeks of DVR heaven, I got sick. While I was stuck in bed, I realized that MythTV can be set up as a network service, which would let me watch TV on my laptop, in bed. I changed one line in the configuration, and restarted it. MythTv refused to start up again. I changed everything back exactly as it was, but that didn't make it work. In fact it would never work again for over a year, but I'd get it out every now and again and tinker. I cleaned out the mysql database and tried weird advice from the forums, but it never worked.

I gave up, and tried other software. Kaffeine was the best. It doesn't have all the cleverness of MythTV, but it has a simple interface and just works. So I've been using it all the time, while occasionally taking a poke at solving my MythTV problems. I managed to get MythTV to see the TV guide from the shepherd utility, but no signals. I didn't mind, I had a $55 DVR, and I could save the recordings and edit them, delete them, transcode, archive, whatever I wanted.

I bought a USB digital TV tuner with an IT9135 from DealExtreme for $11.20, and then paid $5 on ebay for an aerial socket converter so I could connect it to an outside aerial. I bought this for my parents, but linux was too hard for them to use, no matter what the interface. I could get it working on my desktop as a 3rd tuner by following the tutorial.

Then the Ubuntu 12.04 update came out, and killed my device drivers. No TV recording has been possible since then. I've also been very ill for the last 4 months, so I haven't had resources to put into solving it.

I finally had the time and energy to attack the problem again last week, and I can get the USB IT9135 tuner working. Amazingly, not only does it now work with kaffeine, but MythTV now works. I can hardly believe it! Kaffeine sees a single tuner, but MythTV sees two tuners.

The DTV2000DS has the error message in /var/log/dmesg:

[ 11.257035] dvb-usb: found a 'Leadtek WinFast DTV2000DS' in cold state, will try to load a firmware
[ 11.268782] dvb-usb: downloading firmware from file 'dvb-usb-af9015.fw'

[ 13.380200] usbcore: registered new interface driver dvb_usb_af9015


I seem to have some kind of firmware problem, but I don't understand it yet. The firmware is the most recent, just downloaded last week with the firmware for the working IT9135 tuner.
Can anyone help me make my DTV2000DS work?

It might be good to get the whole media centre hived off onto a Raspberry Pi $35 computer, but that could be messy if I can get my PCI card going again.
