Need hardware (and software) to reset power when internet connection is lost
wraith808:
I do have a soldering iron. I'm almost completely inexperienced with soldering, but I have replaced a couple of microswitches in my computer mice a few times.

If you want to get familiar again before trying on your actual parts, there are a few kits on there. I used to pick them up to hone my skills when there was a lapse in my soldering. And they make cool gifts. :)

I do have a soldering iron. I'm almost completely inexperienced with soldering, but I have replaced a couple of microswitches in my computer mice a few times. And I do have an old modem power supply which probably has the same rating as the current one, which I think I could cannibalize for this project. So it looks like that list includes just about everything I'd need, but wouldn't I also need some kind of breadboard wires (jumper cables?) for connecting the RasPi directly to the relay?

If you've got a soldering iron I'd order 2 or 3 of the transistors, (they're the only really temperature sensitive parts), just in case and a small protoboard instead of the breadboard.
Yes, you'll need a lead to plug onto the RasPi GPIO header, (I'd probably butcher an old IDE, SCSI, or floppy cable plug), but for simplicity a purpose made pack of leads is probably cheap enough.
Does the plug on the old PSU match the socket on the modem?
It needs to be a secure fit like the current PSU plug ... and then you need to find a matching socket.
Next time the modem needs a reboot can you take a good pic of the plug end on with a metric ruler for scale?
Actually, if the old PSU is still in working condition, has the same plug, and has the same voltage/current rating as the current one, it'll be easier to cut the cable and insert the relay board into it ... no socket required.

The reason this is a problem anytime I'm not immediately available to spring into action is because I also keep my RasPi connected to at least one cryptocurrency peer-to-peer network in which I can be penalized or deemed less trustworthy if someone tries to connect to my device and it doesn't respond. It's not making me rich, but it's earning me a decent amount of money simply for keeping a device running/connected that I'm already leaving running/connected 24/7 anyway as my personal media server and whatnot.

You buried the lede. What is that, and how does it work? Maybe on a new thread. That sounds interesting...

Considering I have two RasPi 4B's on 24/7 running Docker services, (and spare 2B, 3B, & 3B+), I'm also interested in this. :P

Sorry for my delayed response. I got kind of overwhelmed and stressed out over things, so I decided to take a break from the thread to give myself time to process the information and not act too hastily.
I can report that the Keep Connect suggested by mouser seems to be working nicely since I installed it last Wednesday. It has reset my modem 6 times so far. 3 or 4 of which happened just yesterday alone.
That definitely puts my mind more at ease and allows me to feel less stressed and rushed about putting together my own device to do this for me.

Thanks. That's a good idea. It didn't occur to me to train myself using kits which seem geared toward children. I guess it's more appropriate to think of them as kits for beginners. :Thmbsup:

My old PSU is from a previous model of the same brand of modem, so I'm almost certain they're exactly the same. I'll of course double check before I tear anything apart, but that's the assumption I'm operating under at the moment.
Thanks for the links to the jumper wires and protoboard. It looks like I now have links to everything I need to build the device.

I should clarify that my definition of "a decent amount of money" is really not a lot. I usually start to question whether or not I really need/want something when the cost reaches the $25-50 range.
I tried to write a really brief summary of what it was, but I just kept feeling the need to add more details. So I think making a new thread about it would be appropriate. I'll try to get to that sometime over the next few days. :D
