We’ve all have had to reset our routers or modems at some point because they were acting up. The typical scenario is; unplug the device, wait 30 seconds, plug it back in and wait for it to boot back up. While not hard, this can be an annoyance, especially if accessing the router or power cord is inconvenient. [Taylor] wrote in to tell us about his wireless router that seems to need to be reset more than he’d like. Although the simplest solution may be to get a new router, he thought it would be fun to do something a little more exciting by making a wireless reset controller.
[Taylor] started with an ordinary power strip. He spliced in a relay to the hot side of the AC line, connected to the common and normally-closed pins of the relay. That way, when the relay is not activated, the power strip is powered. Next, a wireless doorbell was re-purposed to act as the transmitter and receiver. The speaker was removed and the output lines connected to a mono-stable 555 timer circuit that [Taylor] made. When the circuit receives a signal from the door bell speaker lines, it will activate the relay for about 30 seconds. Since the relay was wired to supply voltage to the power strip when not activated, activating the relay cuts the power for 30 seconds effectively resetting the router. Now, whenever the router needs a reset, doing so is as easy as pushing the door bell button from anywhere in the house.
