Good to know.
What does Minyatür Mühendislik produce?
Minyatür Mühendislik designs and manufactures giant piano stairs, electricity-generating smart bikes, the LED Race light race, interactive 3D camera games, smart beach coolers, park and playground equipment and brand-specific products in Bursa, Türkiye.
What are piano stairs and how do they work?
Piano stairs are stairs or a flat floor given a piano look with a black-and-white floor covering. Touch-free sensors play notes when you step on them. The sensors are unaffected by rain, snow and dust, and there are two modes: normal piano and playing songs stored in memory.
What is the electricity-generating smart bike for?
People pedal to generate energy and use it to charge their phones. Time, distance and earned rewards are shown in the mobile app, and collected points can be turned into promotions and gifts.
Which park and playground products do you have?
Children’s excavator play equipment, speaking tube, xylophone, telescope and periscope, plus the interactive 3D camera game. They are designed for parks, playgrounds, kindergarten gardens and viewing terraces.
Can products be customised for a brand or venue?
Many of our products are adapted to the brand and the venue. For example, the giant piano system is customised to the brand without structural changes, and napkin holders are produced to match your logo and colours, and figurative sculpture lamps are developed for each venue through 3D design.
