If you know how to make a silicone mold, you could easily make yourself a record out of chocolate or candy. But would you want to put one on your turntable and gunk up the stylus? Techmoan bought a chocolate record from Etsy seller FoodIsArt to see what it sounds like when played. Freezing the disc helps quite a bit.
THE BEST Techmoan
Techmoan checks out another unusual gadget from the past – though this one only dates back to 2007. For a brief period of time, videogame company SEGA’s toy division made a pricey miniature grand piano with mechanical keys that move in time with the music. You could also play it yourself – if your fingers were really tiny.
These days, everyone carries a videophone in their pocket. But before the days of iPhones and Galaxies, calling someone and seeing them at the same time was difficult and expensive to achieve. Techmoan shows off one of the earlier examples of a working video calling system, British Telecom’s VC 7000, which dates back to 1993.
