Now, if anyone ever approaches you to build a board for them for under $200, tell them to F*** off.
Unfortunately, i didn’t. Why? Let’s not talk about it…
Anyway, to achieve the low price, i had to use items and components that were used or just spare parts lying around.
Here’s the parts that i decided to use. My friend provided two components which was a deck which i made for him a few years ago, Caliber IIs. I provided some 83mm Abec clones.
For the electrical components, i used these.
6s4p LG HG2, (used) and had quite a few cycles, $70
4260 190kv sensorless motor, $10 (used)
Janux belt drive system, 12/44 gearing. Original price was $120 USD but it was mine and sitting in the drawer so i used that.
Psychotiller ‘The Coupe’ enclosure (used)
Torqueboards VESC (used)
Arcboards remote (basically a mini remote casing mod to a thumbwheel)
Loop key to keep the costs down and for more reliability
Mt60 connector is awesome for sensorless motors, so clean!
Now you might be wondering. Wtf 6s on 190kv? This is gonna be slow.
Yep, my friend wants this board to be a ‘grocery run’ board. The 15km/h speed is good enough for him, and that’s something i can’t control since changing the gearing will affect the torque, especially since on such a small motor.
Specs wise, it is slow, at 15km/h top speed, but torque is really good, since the gearing is 12/44 on 83mm wheels, and on a 190kv motor. Small yes, 4260s are somewhat rare to be used on DIYs, but let me show you this diagram that i swear by.
Although the build was bottlenecked by the budget, this does not discourage poor craftsmanship on my part, i would still do the best job as i can do make sure the board looks as good as it can get, with its components.
