From Booze to Bots: How a Drunken eBay Bid Created a Real-Life Dalek on Wheels

It started, as so many stories do, with a few drinks and a reckless eBay click. The morning after, a wooden Dalek-Doctor Who’s iconic villain-was en route to a bewildered new owner. But for Tony Goacher and his friend, this impulsive purchase didn’t just gather dust in the garage. Instead, it became the centerpiece of a remarkable DIY transformation: a remote-controlled, motorized, speaking Dalek large enough to fit a human.

What began as a joke quickly evolved into an ambitious robotics project. The wooden Dalek, substantial enough to trap a person, was originally powered by human effort: a captive could shuffle it awkwardly, but the effect was more clumsy cosplay than sci-fi terror. Goacher saw potential for something far more menacing-and mobile.

The technical challenge was formidable. Wheelchair motors were chosen for their torque and reliability, but mounting them to the Dalek’s wooden frame was anything but plug-and-play. Different shaft sizes, mismatched hubs, and awkward mounting points forced Goacher into a crash course in metalwork and welding. Each bolt and bracket brought the Dalek closer to a seamless, rolling menace.

The brains of the operation came courtesy of an ESP32 microcontroller, a favorite among hobbyists for its wireless capabilities. Goacher designed a custom, CNC-routed PCB to house the electronics. The ESP32 acts as a wireless access point, letting operators control the Dalek through a web interface. Two H-bridges drive the motors, while a separate sound board gives a second operator the power to trigger iconic Dalek catchphrases-“Exterminate!” included.

While many build plush, pint-sized Daleks, this one looms with an imposing presence and smooth, motorized movement. The project is a testament to what can happen when mischief, technical skill, and a bit of alcohol-fueled bravado collide. In the age of throwaway online shopping, Goacher’s Dalek is a rare example of buyer’s remorse transformed into engineering triumph.

In the world of DIY robotics, few projects capture the imagination quite like this. It’s a reminder that sometimes, the best adventures begin with a bad decision and the determination to make something extraordinary out of it.
