the signs cover the device it took me a while to find it
When you delete the left part, the wifi channel isn't powered anymore, so the explosive gets powered from the NOT gate. So if you have the right parts but not the left, the right will explode. Also, you can probably alter the wifi channel when paused. I allow for this to be copied, but make sure you don't say what you used from me in your save, otherwise people may investigate and still copy it by removing the vital parts.
awesome idea it can be countered but the effort to put into countering it almost makes it not worth
How exactly does it work?
