Go talk to symbiotica at uwa. Its more bioart but there are overlaps in techniques with diybio. Plus they have some cool and interesting projects like looking at the stromatolites in nearby bay.

Hi, does anyone know if there are any groups in Perth? If not, are there any individuals here from Perth doing DIYBio work by themselves?

I'm not a resident of Perth, but have spent time visiting the bioart and new media communitys there since 2002.
Perth has a wealth of potential partners/collaborators for setting up a biohacker space. Here are one3s I think would be great to talk to. They are North of the river..but will should have contacts south of the river in the universities there.
Cheers

Symbiotica at UWA
http://www.symbiotica.uwa.edu.au/
they make space for Artists like Tissues Culture and Art Project to make artwork using biological systems/materials, and develop apparatus to show their live works in gallery contexts, in a human biology department of UWA.
centre for interdisciplinary arts Studios http://ciastudios.com.au
host interesting interdisciplinary groups and artists
and PVI collective http://pvicollective.com/
one of those groups hosted and instigated CIA that is in the tactical arts (like Critical Art Ensemble)
and PICA http://pica.org.au/
Here I saw the Biennale of Electronic Arts Perth (BEAP) 2002, BIOFEEL: Art and Biology, curated by Oron Catts. and attended the The Aesthetics of care? symposium at Perth Institute of Contemporary Arts (PICA), Northbridge, Western Australia.
Let me know if you need any other pointers.

Making Microbial fuel cells
All aerobic organisms gain the majority of their cellular energy from the movement of high energy electron carriers through their electron transport chains. In humans, as in other animals and plants, this occurs through the electron transport chain located on the inner mitochondrial membrane. In bacteria and other prokaryotic organisms (prokaryotic = cells without a nucleus), it occurs on their cell membrane. There is a lot of interest in finding ways to intercept these high energy electron carriers and using their energy to force electrons through an external circuit1,2. In other words, it is possible to make a battery out of bacteria, or more precisely, a fuel cell. Fuel cells differ from batteries in that they never go flat, so long as they are continuously fed with a source of chemical energy. It is remarkably easy to make a simple fuel cell, using only mud, graphite art pens, wire, and a source of cellulose such as tissue paper. This makes the activity very suitable for a science extension or specialist class, or any class with an integrated STEM focus.
Activity: Stealing electrons from bacteria: making a
microbial fuel cell.
Our extension students researched and made a microbial fuel cell, then visited
Murdoch University to see a lab where such cells were being researched.
Figure 1 Construction of a microbial fuel cell
To Do
Step 1: Collect a polystyrene cup, two 6B graphite art blocks (Koh-i-Noor, www.koh-i-noor.eu, or similar), 2 lengths of 20cm insulated
copper wire("old ethernet wire"), and silicone.
Step 2: Prepare the electrodes: Drill a small hole with a pin or pcb drill into
the graphite. Strip some wire to make approximately 2cm of wire bare. Bend the
bare wire end over so that it presses against the hole you drilled in the
graphite and makes good electrical contact. Cover the bare wire joint, and the
end of the graphite rod with silicone, and allow to dry for 24h. You may optionally
attach a tube and a syringe connector to the electrode so that you can feed the
microbes on it with other substances such as sugar.(Diabetic students (or staff
!) with insulin pumps are great sources of this type of syringe connector!)
(Fuel Cell Figure 1)
Step 3: Place one electrode on the bottom of the polystyrene cup and completely
cover with creek mud, mixed with a small amount of torn up tissue paper (food
for the microbes). You should have approximately the bottom quarter of the cup
covered with mud and paper. (fuel Cell Figure 2)
Step 4: Gently fill the cup up with creek water. Place the other electrode and
wire into the cup. Don't let the two electrodes touch!
Step 5: Connect a sensitive micro-ammeter (eg a multimeter set to read microamps)
to measure the current flow between the two electrodes. It wont be much! It
also is likely to decrease while you are measuring it. How does it change over
time? What is the potential difference (voltage) between the two electrodes?
(Fuel Cell Figure 3)
Possible extensions
Do the cells produce different amounts of energy when they are fed different types of chemicals (eg sucrose versus glucose vesus acetate?)
It is known (R. Cord, pers comm.) that if you “train” the microbial fuel cell by slowly decreasing the resistance of the external circuit, it becomes capable of producing more energy. What visible changes at the electrode surface accompany this? Can you selectively grow organisms that conduct electricity? It is known that such organisms may be important in some sediment communities3.
Can you design a more efficient fuel cell (the one you just made was very weak!)?. Think about flow rates, surface area, and oxygen transport.
Finally, here we all are at Murdoch University, in the lab of Dr Cord, looking at his fuel cells!

There's talk on the slack forum about having a get together this Thursday evening.
We'll post some more details once we sort out a venue.

Oh my goodness! Synthetic bio people in Perth!!!?? I had no idea that there were more of us!
Hello to all, I'm Rhiannon or Rhee. I'm a student in the synthetic biology lab at Harry Perkins. Glad to have found you all. Will have to alert my lab mates as to this forum.

G’day all,
Fortuitously, I’m moving back to Perth today and might tag along on Saturday if that’s alright?

Hi Benedict, Philip, Leon and all other Perth based Outsider Biologists.
This Saturday the 3rd, 2pm at the Artifactory looks interesting.
Oron Catts, Christine, Ito and myself from SymbioticA UWA will be attending to check things out.
Looking forward to it.
Regards
Nathan
