Cheers Richo, It's been really good even though it's output is just over 300W. (It's a 500W 36V motor running at 24V with 2 x 9Ah 12V SLAs..) I haven't had any trouble cutting the lawn unless I leave it way too long or it's too wet, then you just have to go easy but it still works well enough that I...
Saw this today at our depot. Can't wait to take it for a drive!... it was *flat* at the time of the picture ;( but 140km range it pretty good I thought! Yet another EVworks creation :) http://bjblaster.com/forum-pics/aeva/13062011%28002%29.jpg http://bjblaster.com/forum-pics/aeva/13062011%28004%29.j...
Here is the new technology! I just bought some string lights from Red Dot and they come with 3 "AC" batteries :) http://bjblaster.homedns.org/forum-pics/IMG_7283.JPG AC batteries at last :) Bung a few of these in series/parallel and hook 'em straight up to an 3PIM http://forums.aeva.asn.au/smiley...
I suppose it depends where you live, as most councils won't let you have wind as it is classed as noise pollution! Also the safety aspect of a 5m pole in your backyard has to be questioned. That was why I built a VAWT and put it straight on top of my shed. It works, but does it discretely.. I think ...
I have a Latronics Inverter. I love it because it's made from "real" Australian stuff (acquirable), in Australia. Tough as nails. http://www.bjblaster.com/projects/renewable/grid_feed/IMG_2723.JPG and some kyocera panels http://www.bjblaster.com/projects/renewable/grid_feed/IMG_2728.JPG they seems t...

Very nice job :) What annoys me is that we can't build these sort of "affordable" EVs and ride/drive them on the roads "legally". They are much more suitable for an EV than a ~1-2 tonne converted car! Well done again on a awesome build! What sort of range do you get in Lesmurdie? That is some pretty...

I asked my self this same question when building my mains power logger. I decided that even a 1 second intervals, it was accurate enough to work out what my house is using a year. You need to scale the project according to time. If you want to smash a cell in 5 minutes, then you need more points to ...

I can't wait to build another one! The Big Red Car is still going strong, and I gave up on the Mk3 Big Blue Car for the time being as the frame is too heavy. I took the kids to school the other day in the BRC... What a blast! 24V is the future of school transportation! 48V would be awesome for big k...

I never really thought about this until now, but how does an AC induction motor actually do regen? Does it have to have some sort of "back emf" or do you excite one of the other phase windings to get a magnetic field to generate power with? I have seen many people modifying the rotor to except perm ...
Hey that's cool, how did you get that micro symbol in there coulomb? Here is a pic of my logger. http://bjblaster.homedns.org/blog/fp-content/images/img_3422.jpg I got the Current Transformers from RS for $3 each. They output 1V for 1A using a 1K snubber resistor so it's easy to do the calulations. ...
I tried for hours to get it to work under linux, no go. It seems M$ haven't released all of the transport info for mms so you can't view wmp9 mms streams just yet Let the hacking begin!

Do they ever! It was great watching them "bust a nut" (no pun intended for the previous photo!) to beat their mates on a crank off
