hey guys, havent been tinkering a lot lately, mostly because I simply enjoyed my topspeed, but during xmas I had some time to fiddle on something I wanted to do in a while now: electrify my loaded cantellated tesseract in a lightweight way.
while my topspeed really is a gorgeous carver, its not a very light board. was using it for more than daily commutes lately and I quite often ran into the issue of carrying it around through shops, crowds, etc.
been using my tesseract for a while now without a motor and I think its a really really great and versatile board. I also felt like 2 motors is actually overkill, never really needed the power and ran torqueboards ESC on lowest acceleration settings. I also feel like beyond 40km/h I actually have to stop carving and then the fun is pretty much gone for me. :lol:
first shot:
first iteration:
final result:
Part list:
Board & Hardware: Loaded Cantellated Tesseract, 80A Kegels (*update: back to 90mm flywheels 75A), 44° Calibers, front wedged by 6° to make it 50°, rear kept at 44°. I like a slightly more agile front compared to rear!
Motor and Mount: 1x 6355 R-Specc & Enertion Aluminum/Carbon mount
Gearing: 15T -> 36T = topspeed of 43km/h. *update: 16/36T with 15mm belt, theoretical topspeed 52kph, reached 45kph *update2: changed back to 15/36T due to heat issues from wide gearing. sk3 6374 168kV incoming!
1x VESC
10S4P DIY Battery, currently lent from TopSpeed build
Described the board here already, the Kegels are more uncomfortable than my 90mm 75A flywheels and less grippy too after they are broken in, but they are quite a bit lighter (200g total)! *update: screw the weight, the abecs ride is so much smoother than the kegels with much better grip on rough surfaces - back to abecs and not looking back!!
After trying torques V1 mount, I tested the enertion mount this time. it definitely is more unique in its approach and for the calibers, its also a great looking and very solid choice - less flexible but if you dont need the flexibility I can highly recommend it too. I didnt weight them, but it feels like the enertion approach is a little lighter than the torque v1 ... and easier to assemble too. the upside of the reduced flexibility.
Finally I got my first VESC. Took me 20min to set everything up, tested the FOC mode too - overall it feels a LOT more advanced than the torqueboard ESCs with 4 major advantages: super smooth spinup, very very silent, a working battery cutoff voltage and lastly its really really small! Im quite in love with that unit, mostly because it allows a much smaller case.
took one off the latest enertion batches - HW4.10 - its well made with the exception of one little detail: needed a different layout of the battery connectors, so I opened up the shrink tube and found that only a fraction of the seemingly thick cable was actually soldered to the capacitor board. corrected that slight oversight with some soldering, also made the connecting cables a little longer to allow the way I want to place the VESC - rest of the assembly has been working flawlessly though. plug in and go basically.
fist spinup in FOC mode after flawless autodetection of all motor parameters:

I also followed the guide on enertion forums here to set up a nunchuck direct connection to the vesc - and put all of it into a neat shrink tube package. think for this board Ill be fine with my nunchuck, curious about a built in nunchuck compared to the wiiceiver, which has no idea about the ESCs. my biggest complaint about wiiceiver has been, that it doesnt actually know about how fast the engine spins for the cruise control button. it only derived the motor rpm from your current lever position. im hoping now with the VESC, that I could theoretically push the board to my desired speed, hit cruise control and stay at that speed. not sure how it works, ill find out very soon.
For this build Im also skipping the quite heavy, quite large and also quite expensive high current switch and just go for a lightweight XT60 or XT90 loopkey from sl33py here. its really perfect - light, sturdy and protects your board against curious colleagues
thanks to the heavily reduced electronic package with the same DIY 10S4P TopSpeed battery, I can run a 45x15cm case instead of the topspeed 60x15cm case!! its insane - check out the comparison of the large topspeed case vs. the tesseract form factor (case not built yet).
comparison of the 2 boards and cases:
my topspeed rear section is 2 giant torqueboard escs, 1x giant high current switch, receiver, cables. my tesseract rear is only 1x vesc with directly attached nunchuck receiver and future loopkey switch:
only the tesseract next to the giant topspeed case
waiting for the last parts to build the tesseract case now, otherwise Im good to go for spring. will weight and report back once its fully assembled. 8)
p.s.: after getting full vacuum bagging equipment I now rebuild the board completely *click*
