i am going to make 2 small ebikes for a camper van, but i want to run them at 36v so they have a bit of power. what do you think the best way to charge them from 12v would be. do you think it would be best just to use a 12v inverter to 240v then to a 36v charger iam in the uk so 240v, or do you thin...

had the kart wheels come i ordered so thinking of something like this.
i might run 13s 10p for now but i will see what i can fit into it when i start building.

so i am looking at building a scooter something like this one on youtube https://www.youtube.com/watch?v=3UdEitMz0Ew i have been looking at 10x4.50 gokart rims. don't no how i am going to sort out the braking yet. i have a 80-100 rc motor also 3000w controller. but i really want to use a esc so i ca...

its because they use cheap crap cells thats why they was having such a bad problem with voltage sag which led to having eco mode lol.
just buy the best you can afford.

email sent. i put a 3d print stl aswell if you can get it printed out you could test the fit before you get them cut.

the connection on these is crap and its just a matter of time before it face plants you, your best off with a gt2b and 3d printed housing.
trust me going 20mph and having no brakes is no fun.

pm me your email. i have put a 8mm hole in the center but i can put what ever size the want.

the gt2e sucks you can swap the connectors over inside the remote. but your best just to get a gt2b then you can use a 3d printed case.

cheers- well thats my problem at the moment- i gave to have the parts fabricated by a company at a cost ...so im limited really..and hence why they are not that cheap to make- (and sell on) xadmx-That housing is nice- whats the scooter you based it on? i made it myself. it did have a balanceboard w...

i used your gtb2 housing on my daughters scooter. it did have a 63mm motor until it broke so now has a 50mm until i get the 63mm one fixed.

how is the alien drive controller have you had any connection or set up issues. could you post a couple of pics of it in your hand. i am thinking of ordering a couple of these.
thanks

i have just bought a few of these below in the link htd 5m, 17.5mm but only 12 tooth. so the next belt size down is 3m but you might have to go with 20t is 18mm. the next size down is 3m 16t thats 15mm http://www.ebay.co.uk/itm/262632205507?_trksid=p2060353.m2749.l2649&var=561532094975&ssPageName=ST...

found this link so will put it here for reference, its a cheap foam flyer but the controller looks like a good cheap case for putting electronics in.

i have been looking to improve the remote for my electric skateboard. the one i have at the moment is made from a gt2e controller http://i113.photobucket.com/albums/n213/oadamo/IMG_0922_zpsdr3rxglb.jpg but i have seen a few small bluetooth game controllers on the bay, has anyone had a mess about wit...

could just use some server power supplys.

why not just wait for the 6 to come out.

your better off just making one of these to suit your needs its a lot cheaper. https://endless-sphere.com/forums/viewtopic.php?f=3&t=40142#p586436. i printed out a box and to put it in with no heat sink and never had a problem. http://i113.photobucket.com/albums/n213/oadamo/IMG_2013_zpsbtuvbhc4.jpg ...

i thought that esc is for a heli, has it got a brake or just a drag brake when you let off the throttle.

Hi there, I'm not finished with my project yet, but have started to write about it: https://endless-sphere.com/forums/viewtopic.php?f=35&t=84487 Have a look at what I am using - it should be suitable.. Keith i have bought a castle creations esc so i am sorted now. but will keep an eye on your build...

surface area for the friction, the small shaft is not trying to move that much per revolution, so the force transferred works out well. If you keep it down below 3-600 W per motor, that's a fun vehicle. Maybe you missed this. The gear ratio is around 30 to 1 If you use an 83 mm wheel, it makes sens...

...what is the weight and how many $$$$ s in material is in that housing ? the complete box it is about 100gram with no batteries in it or fitting, 1kg of wire i get for about £8 so its about 80p each or i think thats about a dollar each just for the printing. i was thinking of using them to make a...

good idea for rigidity against vibration but heat disipation :shock: this was only just to test the idea, but if you look at the layout of the batteries in the box i have left the battery part not fully enclosed for air cooling later on, i just need to print out a few and see there is best to imple...

after seeing the thread for the modular box i thought i would have a go at making my own. this is what i come up with so far 8s per pack. i have designed it for short rivnuts on copper plate but i didn't have any so i have just used copper clad board for now with some nuts solered to it. i still hav...

i designed this a while ago but just found the drawing out and uploaded it.

this was just a prototype i hav never put it together because i am just lazy lol.

funny you should put this on here as i have been designing and making a exo-skeleton suit for the past 3/4 years. i am using hydraulics driven by an electric motor with circulating system and proportioning valves of my own design. so far i have only run it off a power supply but soon i hope to make ...
