Motorizing speed championos cars

A LEGO fan and electronics enthusiast is exploring the possibility of motorizing Speed Champions cars using custom-built electronics, potentially replacing the standard Powered Up Technic hub with a smaller, more efficient microcontroller. The user, identified as /u/tottero123, shared their thoughts on the LEGO subreddit, sparking a discussion among fellow LEGO and tech enthusiasts.

The core idea revolves around the size disparity between the Powered Up Technic hub and modern microcontrollers. The user notes that the hub, which includes four ports, a light, and a button, is quite large compared to the size of a microcontroller, which can be as small as a fingernail. This observation led to the concept of creating a custom solution to drive DC motors, servos, and other components within a smaller space.

The post invites community input, specifically asking for ideas on alternative methods for driving DC motors beyond using transistors. This open call for suggestions highlights the collaborative spirit of the LEGO community, where members often share their knowledge and expertise to improve and innovate.

For those interested in experimenting with LEGO and electronics, you might find a LEGO Technic set helpful for learning and experimentation.
