Hands-on DIY Engineering

Cheap motors, dead power banks and parts other people throw away, rewired into machines that actually work.

What we build

Four kinds of projects keep landing on the bench.

  • Motors & machines

    Tiny 3V and 480-size DC motors turned into pumps, fans, grinders and little machines that do real work.

  • Power & batteries

    Power banks, chargers and spot welders built around salvaged cells and low-cost modules.

  • Trash to treasure

    Bottles, cans, cardboard and dead gadgets rescued from the bin and rebuilt into useful tools.

  • Toys & vehicles

    Cardboard cars, bottle boats and motorized toys you can put together in an afternoon.

Know your circuit before you build it

Some projects involve mains voltage, high current or lithium cells, which can shock, burn or catch fire. Only attempt a build if you have the knowledge and the right protection: insulated tools, eye protection and a fire-safe bench.
