In July we purchased a 2012 I-miev ex-demo (Dec 2012 rego) from booths motor group Gosford for $25000 it’s now November so in 3-4 months we have done ~5000km. it’s had its 1500km service and the next service is at 15000km or 1 year.
Driving a EV is like driving a classic car, you rarely see them on the road and there is a nice community around them.
Like I said this is post number one more are coming !
To upload I’m using the fronius easy card talking serial to a spare laptop ( will replace laptop with a raspi when i get a wireless card for it), because the sunpower inverter is a re-badged fronius i am using fslurp to do the serial commands
The only thing which needs to be changed is my device type is 0x97 Sunpower SPR-3501F-2, which is listed by fslurp as a unknown device.
So I decided to build a quad mainly the one designed by the diydrones.com people, there are 2 suppliers of the kit jdrones and udrones. one is based in Asia the other in the US.
I decided to be slack and buy the pre-soldered kit, I can solder and it’s not like it was anything hard like surface mount. Big NOTE when they say pre-soldered they don’t mean the entire kit has be soldered you still have to solder 24 bullet connectors and the power distribution board, and for some reason they give you the magnetometer attached by cable not soldered directly to a header on a board like they recommend.
What I forgot to buy is some headers: http://store.jdrones.com/product_p/conhead20angle.htm and http://store.jdrones.com/product_p/conhead20str.htm
Ok so this isn’t enough to make it fly and yes you’ve just spent nearly a AU$1000 you’ll also need to get a Battery, and a radio. For that I tried the hobbyking.com shop. Note: if it’s not in stock in the Australian warehouse delivery times seem a bit slow.Also LiPo battery’s can not be shipped by air, make sure you buy in Australia for those.
Lastly is the radio the most expensive single item after the kit. I’m trying to get my hand on this but apparently the queue is long and the might take months. why so popular you ask well it cost like $60. and something with that many channels cost normally around $200+ so If nothing ships soon I’m looking at buying one of these Futaba 7c and probably from the more local hobby store dune planes
What you need to know about the TX RX radio is basically get 2.4 GHz otherwise the local model aircraft club will not let you fly near them. and you need at least 6 channels and any more than 8 channels is pointless
The diydrone has a very smart and easily programmable flight controller if you want cheap and no as intelligent have a look at kkmulticopter
Actually got around to looking a CUDA on Nvidia cards at work yesterday.
Got the SDK and sample code up and running on the mac pro, next thing to do is find some maths problem to do on it which will be faster than on a CPU / Grid. well at least that it will be faster given a better GPU the NVIDIA GT 120 isn’t that fast considering there is 2 Xenon quad core chips 2.4ghz. on the mac then there at 6 macs connected to the Xgrid. so it will be a bit hard to do a direct comparison.
Also had a informal meeting with the lab manager from physics we discussed how that for ever increasing amount of remote courses at the university how he plans to do physics labs for the astronomy course next year.
Ended up sending him to have a look at the UTS remote labs http://remotelabs.eng.uts.edu.au/ and told him to keep us posted since it’s all of interest.
So any ideas how to show that CUDA and GPU computing is useful ? or how to conduct an astronomy lab when your students are in Queensland ?
