As mentioned before, one kit is destined to light up the control panel, the other one will light up the false panel that I am planning.

A few posts ago I mentioned that I had bought some windscreen wiper motors. Here they are cleaned and stripped next to a 12V sealed motor cycle battery.
The steel turn arm was removed by clamping tightly the turn arm in a vice, getting a friend to help hold onto the motor to prevent it turning as I undid the nut. They are well fixed on!! The brass mounting was removed by removing the small nuts using socket spanner.
A bit of CRC was used to ease the nuts off as they had welded on over time. All nuts and bots were retained for future mounting. Then with some more CRC the motor was thoroughly cleaned up.
Just for all you car boffins out there... Here is a photo of what they would have looked like in the original car...
And this is what I sort of hope to achieve with them, like Robert's K-9.

More than 120 artists' dolls will soon be on display at Federation Square, writes Frances Atkinson.

THERE ARE TWO Sayraphim Lothians. One has pale skin, shiny hair and large eyes, the other has shiny hair, large eyes and pale green fur. "I'm so happy with it," the real Lothian says, gently stroking the little monster's hair.
The creature sitting quietly in the corner represents a part of Lothian she'd rather not talk about in detail. "I suppose she represents my own insecurities. She's a monster who is trying to fit into human society. She's wearing a handmade dress and has jewellery that doesn't quite match."
The furry doll is part of Totem, an installation made up of more than 120 dolls that will fill the hollow walls of the atrium at Federation Square as part of the Melbourne Fringe Festival.
Lothian approached artists from Australia and around the world and asked them to create a doll with soul - a piece that "reflected their inner identities". A few found the question so personal they couldn't commit to the project, but many others found the idea of creating a doll that embodies some aspect of themselves an irresistible challenge.
Lothian describes herself as an art mercenary who works in television, film and theatre. She's also a graphic and web designer who is happy to do anything artistic, providing she's paid for it:
"Which is basically what most artists do to prevent working in call centres." Lothian also worked as a puppet technician on Spike Jonze's yet-to-be-released film Where the Wild Things Are, based on Maurice Sendak's classic children's book of the same name.
At her headquarters, the Auspicious Arts Incubator in Southbank, Lothian's studio resembles a surreal mail centre where packages in brown paper and bubble wrap of assorted sizes take up every inch of space. There's a Frida Kahlo-inspired skeleton, a traditional-looking doll with a fabric cigarette hanging from its mouth, a brightly coloured, papier-mache doll featuring Andy Warhol's face.
The latest arrivals are on the desk. One is a small sculpture of a rabbit with large belly, protruding front teeth and what Lothian suspects are real whiskers. It hangs on to a smaller bunny doll, in the same manner a toddler might grasp a favourite toy: upside down, by one leg.
Lothian said the artist, American Carisa Swenson, was initially worried Australian audiences might not like the doll because of our prejudice against rabbits and the damage they can do to the environment. Lothian doesn't really know what Swenson is trying to convey with her doll, but adds, "I'm fine with that. I don't try and interpret them too much." But, she adds, "all art is personal because it comes through this filter of their own experiences".
Of course, dolls don't always equate with sweet. In his book A Room Full of Toys, Alberto Manguel observes, "The body of a doll is always slightly disturbing." He might well be talking about a piece submitted for the project by Melbourne artist Jon Beinart entitled bubbapilla - a stack of five headless baby dolls which are connected with only one head at the top.
With each set of arms and legs pointing to the front, it does resemble a bizarre baby/caterpillar hybrid that is undeniably strange and beautiful. In contrast, artist Madeleine Hoxley drew on her science background to create a free-form quilted skeleton that's anatomically correct. Black stitching provides the shading while caffeine-coloured fabric helps promote a creamy, bone-like pallor.
One of the most captivating pieces is by American artist Beth Robinson. Her doll, about 45 centimetres tall, is a woman wearing a dress made from vintage fabric. She has long, dark hair, a hank of Robinson's own locks, and four arms. One set reaches up to her head in despair or frustration, the other holds tiny dressmaker's pins and a black voodoo doll. Her eyes are entirely silver - sightless and watchful at the same time.
Via email, Robinson says, "I spent a lot of time thinking about who I am as an artist and a person and how the two work together to create me."
No less curious are five large bald dolls made out of simple calico by Melbourne artist Rachel Hughes. Delivered in a woven basket, each face is delicately painted in muted colours. Lothian suspects they are partly a self-portrait of Hughes and each of her four sisters. "I think they're incredible," says Lothian. "Every choice an artist makes tells you something about them."
While some of the pieces are as far removed from a prosthesis-coloured Barbie or pimped-up Bratz doll that you can get, many are influenced by traditional doll-makers. Lothian said she was inspired to create Totem partly because of her own childhood connections with dolls.
Her grandmother Marj was a member of the CWA and spent a lifetime creating dolls for Lothian and her sister. "She knew about the project but developed dementia and died early this year, so I've dedicated Totem to her memory."
Melbourne artist Jade Burstall is making a documentary about Totem that will run on a large screen during the exhibition. "'I'm not a crafty person but I got on board because I was drawn to the idea of dolls with souls. The installation process will take Lothian two days to complete and Burstall plans to capture much of it on film.
The project has also inspired debate between artists about the nature and craft of making dolls, and the process of transformation that turns a doll into a work of art. Lothian believes environment has a lot do with it.
"Some dolls are clearly not playthings. Most of the dolls in Totem are one-of-a-kind art dolls." However, Lothian hopes audiences will connect with the installation. "Totem is not just about self-identity, it's like a vox pop of how a section of society see themselves. Each doll has been created using a wide range of techniques that showcase how varied the craft can be."
Totem will be on exhibition at the Fracture Galleries, the atrium, Federation Square, city, September 25-October 12. www.melbournefringe.com.au

I also have a couple pieces in the GLC exhibition 19 Sep - 2 Oct at the Moonah Arts Centre. I managed to sell the photo on opening night :-)

Here is a little about the Sabertooth 25A system I am getting. A bit of overkill, but I have read in a few places that under stress that wiper motors can produce 30A peak current! So I don't want to take any risks.Out of the box, the Sabertooth can supply two DC brushed motors with up to 25A each. Peak currents of 50A per channel are achievable for a few seconds.
Overcurrent and thermal protection means you'll never have to worry about killing the driver with accidental stalls or by hooking up too big a motor.
Sabertooth allows you to control two motors with: analog voltage, radio control, serial and packetized serial. You can build many different robots of increasing complexity for years to come with a Sabertooth. Sabertooth has independent and speed + direction operating modes, making it the ideal driver for differential drive (tank style) robots and more.
The operating mode is set with the onboard DIP switches so there are no jumpers to lose. Sabertooth features screw terminal connectors - making it possible for you to build a robot without even soldering.
Sabertooth is the first synchronous regenerative motor driver in its class. The regenerative topology means that your batteries get recharged whenever you command your robot to slow down or reverse. Sabertooth also allows you to make very fast stops and reverses - giving your robot a quick and nimble edge.
Sabertooth has a built in 5V BEC that can provide power to a microcontroller or R/C receiver. The lithium cutoff mode allows Sabertooth to operate safely with lithium ion and lithium polymer battery packs - the highest energy density batteries available.
Sabertooth's transistors are switched at ultrasonic speeds (32kHz) for silent operation.
Sabertooth 2X25 uses 1.3 milliohm MOSFETs in its bridge. Going by other's ridiculous rating schemes this would make it a dual 190A motor driver!

I finally found a place that sells wiper motors in Hobart that have a long shaft! Yeah! :-) Sadly though I couldn't find a left and right motor and will have to flip one over and reverse the polarity to make one run.
This is what they say about it:
