Ninja Warrior Button

Ninja Warrior Button tied to wifi controller
Over the last few weeks I've been playing around at Ape Index Leicester, it's like a ninja warrior training gym with a climbing wall. I'm mostly playing but I've certainly been getting fitter because of it, I was talking to the owner who discussed a big red button project like they have at the end of the ninja warrior course. Wiring one up is tricky because the place is so big so it sounded like a perfect match for some of my ESP8266 work.

It's a simple browser based stopwatch app written with javascript, this is served up from the ESP8266 as an access point. A websocket is opened to transfer data too and from the browser without refreshing the page. When you press start on the screen the light on the button becomes illuminated, when you push the big red button the timer stops counting, so you can start the system from one end of the course and see what time they get at the other end.


This is very much a fun project I threw together in an hour this evening while cutting useless machines. The internals definitely reflect this, thrown together with sticky tape and bits. I used a rechargeable battery for a power supply but some strain relief on the cables would be preferred. Ultimately this system should tie into a larger screen to show the current time but that's future work.
