Thanks Addy, I have been doing a bit more research and came to the same conclusion. I have picked up a spare Hammond aluminium enclosure that was going at work, it should be big enough for the VESC and some small 25mm fans to push some airflow through the inside. I will probably mill the...

Hello all. I built this at the end of 2014 https://endless-sphere.com/forums/viewtopic.php?f=35&t=64407 I used it for about a year but disassembled it due to other commitments and not really finding the time for it. Back then i used a 120A 12s hele esc that had no break function. I want to...

Ran the board a couple of times round the block today while using a GPS tracker on my phone... I think i will get some larger pulleys, at the moment i am running a 12/36 this gives me... with a 14/36 i should get... This is all at nominal voltage. Im not 100% sure that a 14t pulley will...

You can get the cells out of dewalt battery packs this site gives a tutorial http://www.slkelectronics.com/DeWalt/packs.htm There are also a few places that sell the individual cells, however there are a lot of fakes you need to do your research. Datasheet...

Yeah i know i learnt the hard way but i know i can fix it, there are a few threads on forums about reprogramming the atmel chip on the esc i just have to work out if it is worth the effort/risk. At the end of the day the board is not used for commuting and i feel comfortable with it at speed, i...

Got the radio gear in and starting to test it And this thing is an absolute torque monster....i have played around with the esc settings and got the throttle response where i want it. BRAKES - there is none .... the brakes for this heli ESC is on the moment the throttle is returned to...

I love the dirt scooter, i would like to see an option for disk brakes. Do you think it would be possible to just put standard vbrakes or ubrakes on an aluminium rim, assuming it had a large enough sidewall. The brakes should therefore be easy to mount on the base deck....foot room would not be...

Just pre ordered Brunos TX :) it looks good, i cannot seem to find many photos of it tho. I will run initial tests on it, i will probably run with the brake off for a while before doing any mods. Im fairly sure i can hack the chip with some home brew pogo pins directly on the atmel......but i...

Worked out the resistor needed for my cap bank... 1 time constant = CR = 8010uF*470R = 3.8 S ............ after 2 time constants (7.6 seconds) the cap bank should be at roughly 85% capacity total instantaneous current (at max voltage) = v/r = 43.2V/470 = 92mA instantaneous power = v*i =...

UPDATE time ! For some reason this project has become a trickle build, i have been doing little and often to this and am getting closer to the finish. Firstly the wii nunchuck i have received is crap, i have had two so far and neither dongle will power on :( yet the receiver from homann...

They are going to be run in 12s2p configuration, 40V ish at 4.6Ah .... i hope to get at least 8miles of range although i am not entirely sure on what i will get.

Got some more bits ! I found some scrap aluminium plates that i will use to make the Velcro brackets/hold downs they look about 4mm thick. I also cut the keyway on the motor shaft, not bad since it was done with my dremel. + some fancy braiding i had about from my RC stuff.

Hello all, rs4race - They are A123 systems cells they are kinda hard to get hold of (legit cells that is) i got a bulk buy of many cells. These were cells that were deemed dead i got 50 cells cheap then just took the good ones out. I will try recover the bad cells, unlike other lithium...

Batteries are done... Now its time for the next issue, i went looking for enclosures but none are going to be big/slim enough. I am thinking that velcro straps round the cells will be adequate, i see people doing this with lipoly's im not sure i would want a soft cell pack unprotected and that...
