I run escape rooms and I am looking for someone to build me a puzzle/game. I need someone to build me a physical board that contains 12 buttons, all linked to the web. The buttons w...web. The buttons will need to flash randomly and the person playing will have to touch the buttons within X seconds. If they get to the button in time, they will score a point - if they get enough points, a video will start to play The board will need to be 1m x 2m in size and ideally be both battery and mains powered. The successful person will be able to advise on the best (and cheapest) buttons and sensors, and manage the programming to ensure the clicks are registered online. This project could suit two sperate people. If you are interested please contact me and we can discuss. Tha...

BE Dot project Stimulating muscles with the use of electrical signals generated by artificial means is not very new to us. In the year 1780, an Italian physicist and biologist discovered that the muscles of a dead frog can be stimulated using electricity. This marked the beginning of a new branch of biology, called the BE bioelectronics. EMS machines are typically portable with a 5V or 9V supply. Very small currents run from the main unit to a set of pads. The frequency of the current and pulse duration can be adjusted by the EMS unit. They have electrodes that come in pairs of two, four or six, that are in the form of pads. These pads contain adhesive gels that help it retain the position where it is placed. These electrodes pass the impulse generated by the EMS unit, with the hel...
