This is a version of Philcraft's Penny Engine which has it's own USB (5v) powered air compressor built into the base. It is a simple engine using an old UK penny for the base. This example has the normal turned brass flywheel. The penny is dated 1962.
It has a tiny single acting oscillating cylinder, 3mm bore x 4mm stroke. The engine block is supported on two ornate brass pillars, one of which carries the air feed. Air is supplied by a miniature air compressor inside the wooden base. The compressor is powered by a 5v DC supply from a standard USB socket. Exhaust is through a hole in the top of the block. The pillars are mounted on a 1962 UK penny, which is supported on three brass feet fixed to the wood base.| Make | Philcraft |
