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 ;)

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

This looks very promising!

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

--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.

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

Calc center distance of pulleys:

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