I have a simple circuit where 5V signal is fed into a buffer (Nexperia 74LVC1G07), then from the buffer into another device. The buffer is fed 5V by a switching DC-DC (R-78HB5.0-0.5/W). After it's been off for a while, the buffer works, the signal is recognized by the receiver. This continues for some time, minutes, to tens of minutes. Then the buffer stops working. The DC-DC still works as well as the source. If I unplug it and let it sit for an hour, it resets back to working for a while until it stops.

Context:

The setup runs on an ebike 36V battery. Theres a hub motor connected to the same battery (via power controller). The signal source is a torque sensor. The destination is a bike computer.

Any idea what could be causing this? I don't know much about electronics. I learn specific bits to do something but I'm ignorant otherwise. E.g. I know what a buffer does, I understand how it works on high level but I have no clue for example how it could be affected by the rest of the system electrically through noise, EMI, etc. My physics intuition here makes me think there must be some charge buildup happening which dissipates with time when turned off. I've no idea if this is remotely valid, or if it is how to fix it. Any ideas are appreciated!

I did support Carney and I hope he does good things, and I don't think the following scenario would occur but I realize this belief is entirely based on my judgement of Carney's character which could be wrong.

I was thinking about the proposed gas pipeline to the east coast. If Carney hopes to be re-elected, he can't ram a pipeline through Quebec using emergency powers if such exist. Or he'd lose his seats in QC. Instead he's gotta give significant concessions to QC, like ownership, high royalties, etc. Stuff that he and Blanchet can sell to the Quebecers. I think this is certainly possible for a gas pipeline.

But then the following disaster scenario occurred to me. He likely has significant Brookfield investments in that blind trust. He likely has a seat open on that board whenever he quits public service. What if he uses emergency powers to ram a whole bunch of infrastructure, through P3s, where the private partner retains ownership, and the partner is Brookfield. Do as many of those as possible, get kicked out of office and sit on Brookfield's board, that much richer, while we get saddled with an even angrier and vindicated CPC fascism.

Thoughts?

Edit: Thanks for wading into my election PTSD nightmare!

I wanted to buy a pair of pants but I can't see Add to card anywhere. Am I blind?

Niagara Falls—Niagara-on-the-Lake is another close LPC-CPC race that could use any help from non-LPC voters. It used to be a CPC seat.

This page shows a nice visualization of the closest races.

I have a unique opportunity to add a node at the Tower LNB ring. However I'm struggling to source a Meshtastic gateway that meets the requirements I'v been given. Any help would be appreciated.

1. Power will be provided over 48v POE ONLY
2. Remote management is a must, consider both internet provided over ethernet and 4G/LTE as backup (fw updates)
3. Maximum 5db gain antenna can be used positioned on the LNB ring facing N-NW, must not exceed 1400mm in length
4. Must be tuned for exactly 915mhz (l'm thinking cavity filter) to help with Rx.
5. Enclosure and antenna must be pole mounted
6. Absolutely no wifi 2.4 or 5ghz
7. 500CND budget I'd like a set it and forget it approach. ls it even worth it?
