electric lawn mower

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...

Here is the new technology!

Grid Connect PV systems

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 ...

Custom Built Rat E-Trike

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 ...

Soapbox on regenerative braking

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 ...
