  • Tangentially related: we’ve got an electric sit/stand desk that sometimes needs the controller resetting, but the only way to do so is to unplug it and wait for the capacitors to discharge, which takes at least 12 hours or so. I wonder if I can just add a push button and a resistor… 30 seconds is annoying, but would be a huge upgrade from can’t-move-desk-until-tomorrow…


  • The solar/battery models don’t run 24/7 - you can trigger them remotely (so you can check the live feed whenever) or they can trigger with motion. Still perfectly useful for a bunch of use cases (e.g. just checking if you closed something, or installed somewhere that motion sensing is reliable like a low-traffic corridor) but not super useful for, say, a front door.


  • Just to second this - I’ve upgraded all but one camera to Reolink RLC-810A a few years back and they’re rock solid. All offline (no internet, but connected to Home Assistant on a separate LAN), all powered by a cheap unmanaged PoE switch from PB Tech. (Edit: this one).

    They’re recording 24/7 to their local memory, but I almost entirely use them via Home Assistant’s ability to pull a JPEG directly from the camera (because it takes a fraction of a second at 4k vs the unbearable pain of waiting >10s for video to buffer even at SD resolution).



  • tips on soldering

    In addition to the other comments - if you’re soldering to something that can sink a lot of heat (a great big copper connector, or the ground plane on a circuit board), you will probably need a fairly broad tip. A finer tip can’t transfer heat fast enough, so you end up having to hold it in contact for far too long to get hot enough to melt the solder and (counterintuitively) you end up melting plastic or overheating components. Doubly so if you’ve cranked up the heat to help.


  • FedEx have their own drivers in Auckland?

    I can confirm that they have at least one.

    To be fair though, our supplier invests a fairly large chunk of money in freight, and in the past ran their own dedicated flights when the previous carrier (maybe TNT? Can’t remember) wasn’t reliable enough. I have no idea if FedEx is that good in general or if it’s only for these sort of high-priority customers.











  • I use a dumb 433MHz wireless doorbell (apparently this one on Ali Express, but the exact one doesn’t matter) with a Sonoff RF Bridge running Tasmota. It’s far faster and more reliable than anything with the smarts built into the button, and the battery lasts at least a few years.

    I’ve got it set up to take a snapshot on the front door and driveway cameras, send a push notification with the front door camera, announce on the speakers that someone’s at the door, and turn on the outdoor lights at night.

    The doorbell was $8 shipped, the RF Bridge was somewhere in the mid $20s but I already had it for some door sensors, and if you don’t already have a camera, a decent Reolink is under $150 shipped directly (or under $250 from a physical shop in NZ like PB Tech).


  • I’ve had a Chromecast and not apple tv and its quite decent.

    The main thing that bugs me about my Chromecast is the gradual loss of functionality over time, presumably as a part of planned obsolescence or deliberately crippling features to make you pay for premium options.

    Next time I need to replace/upgrade something, I think I’m just going to skip streaming at all and just hide a full desktop somewhere and pirate everything.


  • I’m thinking I might go without PoE and just meet my current need, then add a PoE switch to support cameras if or when I get them.

    That’s more or less what I did when the dirt cheap AliExpress cameras died - just got a PoE switch from PB Tech and a small pile of Reolink cameras (RLC810A). Definitely the best value-for-money, and works well with Home Assistant. Way better than those stupid splitters or having a pile of individual POE injectors.
