Changing motor and pulleys for 2019 spring, going for lower topspeeds and more torque;

(((22.2*270)/(48/14)*(90*3.1415))/1000/1000)*60=29.65748782500000000000

22.2 = nominal voltage 
270 = 270kv motor
48 = wheel pulley
14 = motor pulley
90 = wheel diameter in mm

Alright, this is overdue!

I rebuild nearly all of it for 2016 summer.

Replaced bearings in wheel with Zealous
Replaced trucks on board with Caliber 50's
Added shockpads
Replaced my motormount with one of AlienDriveSystems.
Replaced printed motorpulley with alu one from beltingonline
Replaced batterybox with a different one
Made a new lighting system, this time with RGBW leds
Recoded entire TX/RX software, now much higher resolution (will publish soonish)
Replaced the 6S 5Ah battery with a fresh one (seems the old one had 1-2 pierced cells , eww)

All and all, superwelcome mods! Check the 2016 gallery up top for new pics.

Yay! Just remade my controller, from a wired into a wireless controller \o/

Features;

zarya's 'NrfSensorNode v1' board ( https://nurdspace.nl/NrfSensorNode ), which has;
- ams1117 regulator
- arduino pro mini
- nrf24l01
adafruit powerboost 500c
500mah lipo (also from adafruit)

powerswitch (soldered into the battery, ha)
potmeter (some random one i found)
housing (charger of some thing, no clue, it fit my hand :D )

--buZz (talk) 23:00, 13 June 2015 (CEST)

Woot! 17 hours printing gave me this as new battery case :D

Tried to make a 3S cell, its currently charging. Not sure how well this is going to feed the many amps required ;)

--buZz (talk) 00:05, 27 May 2015 (CEST)

Added lights \o/ Yay NURDLed

--buZz (talk) 02:55, 21 May 2015 (CEST)

Some maff for max speed;

(((22.2*280)/(44/16)*(90*3.1415))/1000/1000)*60=38.34503476363636363620

22.2 = nominal voltage 
280 = 280kv motor
44 = wheel pulley
16 = motor pulley
90 = wheel diameter in mm

--buZz (talk) 12:23, 18 May 2015 (CEST)

Published some models;

http://www.thingiverse.com/thing:833057 (wheel pulleys, both 44 and 48 teeth versions)
http://www.thingiverse.com/thing:833053 (motor pulley, 16 teeth version)
http://www.thingiverse.com/thing:804463 (updated motor mount)

--buZz (talk) 23:55, 17 May 2015 (CEST)

Some videos of me in movement!!

--buZz (talk) 20:14, 17 May 2015 (CEST)

Made the mount smaller and firmer.

--buZz (talk) 14:24, 17 May 2015 (CEST)

Been trying out a mount and pulleys and the belt. Results thusfar;

This looks very promising!

--buZz (talk) 13:33, 16 May 2015 (CEST)

Belts arrived \o/

--buZz (talk) 18:38, 11 May 2015 (CEST)

Ordered ESC and programming card.

Should arrive in a couple of days.

--buZz (talk) 13:12, 10 May 2015 (CEST)

Used http://www.bbman.com/catalog/belt-length-calculator.html to calculate the center distances. Got to these results thusfar;

12/40 with 270mm gets 66.3
16/40 with 270mm gets 62.1
16/44 with 270mm gets 55.6

12/40 with 295mm gets 79.4
12/44 with 295mm gets 73.1
15/40 with 295mm gets 76.2
15/44 with 295mm gets 70.0
16/44 with 295mm gets 68.9

--buZz (talk) 01:41, 4 May 2015 (CEST)

Ordered belts \o/ 270 and 295mm in size , 15mm wide, from beltingonline.com, should be here in a week :)

--buZz (talk) 02:10, 3 May 2015 (CEST)

Worked on motormount attempt today, released results already on http://www.thingiverse.com/thing:804463

Gotta go mess around with;

--buZz (talk) 16:45, 29 April 2015 (CEST)

Ok, sad, don't see anything on i2c :/ Maybe I should have tested this nunchuk a bit more...

--buZz (talk) 04:21, 26 April 2015 (CEST)

Modding the wii nunchuk receiver onto a 'arduino pro mini' board with a 3.3V regulator combined.

Also adding a i2c breakout (for future addition?) and ~something for WS2812 output.

--buZz (talk) 22:49, 25 April 2015 (CEST)

So, i've started a buildlog here to keep track of order etc.

Mounted the pulley today, and, as i suspected i need longer M5 bolts. About 70mm should do. So, need to grab some of those soon.

Looks and feels proper enough, so will be ordering a HTD belt soon. Need to find a 280/290 5M 15MM HTD belt, any leads? :)

Also, remember to grab this for front pulley; http://www.thingiverse.com/thing:16627

Just some links

http://diyelectricskateboard.com/

http://www.beltingonline.com/

Calc center distance of pulleys:

https://sdp-si.com/estore_cd

Came to about 5.5 to 7.5cm distance, will need to redo when i know actual belt size etc

Printable???

Let's try this :)
