I upgraded ROKR marble run set with a 12V motor + speed controller

#marblerun #rokr #diy #modification Since the existing motor on the ‪@rokr_official‬ marble run link pack was struggling and was too slow, I had decided to upgrade it and modify the kit by replacing the motor and adding a speed controller with a switch. In this video I will walk you through on how I have done it and what is the best motor you can use to achieve that ultimate speed and power. It is also entirely up to you if you would like the motor to be plugged into mains or use a 9V battery of which I believe would be perfectly enough for most people here. You will see at the end of the video how well it all is running and what difference does that speed and power makes. Here is the list of items that I used, but not all may be available in all countries: Motor: https://amzlink.to/az0IOc6DJBGhg Speed Controller: https://amzlink.to/az0rZQaG3w4et 9V Battery: https://amzlink.to/az0C51nOVX8NQ Battery Connector: https://amzlink.to/az0ttymumPAzk If you enjoyed this video, please leave a like, subscribe and click the bell icon so you don’t miss out on more build videos and check out this and other amazing diy kits by ROKR​⁠/Robotime here: https://tidd.ly/4kAJTGW and remember to save this link and use my promo code ‘martins15’ to receive 15% off on everything.
