Wow. Just happened to run into this post…
Maybe our electrical engineers on the forum have learned their lessons elsewhere, but all my bulds have been taken apart multiple times. We should start a mistakes thread/look what I broke thread, if there isnt already one lol.
Things Ive screwed up:
More VESC’s than I care to admit.
Jacobs hub motors. LOst side plate bolts, shifted the press fit axle sleeve at the center of the stator rippong off the phase leads, shorted the stator winding trying to use it as a 1WD, slipped the urathane wheels(not my fault).
Bent axles on the carvon truck hanger.
Damaged the threads in the rotor of a Torqueboards hub motor when the screws loosened while riding.
Almost died learning over powered dual diagonal drive on a super short board is a bad idea.
Saw white spots for hours after I shorted a battery lead to ground while trying to repair a solder joint on my anti spark switch.
Ran PPM wires too close to phase wires and got intermittant cutouts
Chewed up a belt or two braking from high speed without enough belt tension.
Didnt use grommets on an enclousure and wore through the phase wires.
Broke corners off an enclousure when a couple of fasteners vibrated loose during a long ride.
Blew up a speed controller going down a long hill with a fully charged battery on the Onan X2.
Had both wheels come flying off of 190kv hub motors on 12S voltage when a newb hit the accelerator while holding the board.
Almost died when my boosted board cutout due to full charge going down hill.
Fried multiple CAN transceivers on my VESC’s trying to get a 4WD CAN BUS set up going.
Had a board stolen cjz I left it i the car overnight chistmas eve(theives favorite night).
Things Ive learned the hard way:
A little glue on connectors goes a long way.
Velcro isnt as useful as I thought it would be.
I put shrink tube over bullet connectors to keep them together
I take new parts apart to put loctite all over them.
I use batteries with more current rating and capacity than I think you’ll need.
VESC’s blow up if I skipped any of these steps.
Found out putting your receiver behind your back for a high speed tuck is a bad idea.
The CAN BUS terminal resistor needs to be changed to connect more than two VESC’s via CAN BUS.
How to use a reflow station.
How to brush all mistakes Ive made under the rug to make myself feel better about blowing serious $ on this hobby.
Nothing in this industry was designed for super heavy people :(.
Wear a helmet
Dont leave $2k skateboards in your car.
