When our Netgear CM2050V started flaking out and lost internet connection daily, our ISP just kept advising us to power cycle the modem. Despite a strong signal from the ISP, the cable modem would not reconnect by itself without a power cycle.
We found that inconvenient, so I designed this electronic gizmo to automatically power cycle the cable modem if the connection is lost for a (configurable) time period, using a LED on the front of the cable modem to determine if the connection was lost.
The 3D-printable photocell clip in this design is specific to the CM2050V cable modem. Our modem is located in a dark closet so I don't need to worry about light leakage from other sources, but the clip is in black PLA to limit light intrusion as much as possible.
Parts I used for the electronics (see photo) were as follows:
* Male power plug (matches the one on the cable modem's 12V power adapter)
* Female power connector (matches the one on the cable modem)
* Arduino Nano (availabl
