  • Yep, My prediction was more the idea of a first try. Cash and run is normally the type of criminal more willing to try with less planning, etc.

    To work with machinery needs both the ability to move it in a way cops won’t notice. So take minimal organisation. Cops confronted with an assumed ICE agent taking expensive machinery are much more likely to draw their own gun then accept it’s a ICE agent.

    Stuff small enough to fit in a white van like generators or tools, though. Yep, would just look like immigrants are being removed.

    Heck, could even kidnap Musk that way and likely get away with it with a little thought.

    I am in no way recommending anyone start kidnapping billionaires to help defund trump. (Nudge nudge). Nope you should not do that (very obvious unsubtle wink) .












  • Much depends on the house. Traditional UK family housing with 2 plus stories and fron and back windows are far easier then modern subdivided multi flat buildings.

    The older building allowed concentrating on air flow by opening highest widows and drawing curtains that face the mid day sun. While opening lower windows on the low sun side. During the night crated a natural flow of air.

    Modern housing means the internal divisions and often lack of non concreted areas. Often prevent cooler air being able to flow. Or existing if the concrete hass 0 shading from the days sun,

    Single level can still do it. But much less effective as the temp difference is less. But when the internal layout limits airflow from the high sun to low non sun side. Way harder.

    Downstairs fans running overnight while sleeping with upstairs top windows open. Can be a huge difference.

    Or just remembering the direction goal of fans. iE removing higher air while pulling in from lower.

    It’s common for folks to place the fan between them and the window blowing at the bed. This is the worst thing as you are preventing hot air from leaving. Assuming you are not on the lowest floor.






  • Yep that can work. But ignores all the well documented and supported development community comments I pointed to while also indicating other options exist.

    As for.

    Turning some switches on and off while monitoring input values doesn’t sound very computationally intensive.

    You realise IO wise that describes your keyboard and mouse interaction on the most powerful gaming PCs.

    It’s what you do with the results that matters.

    GPIO supports a fair bit more then the on and off input and output. It’s slow compared to other systems. But has multiple serial protocols of differing types. Simple GUI displays can also be run via gpio connections. Low Res Lidar devices are available connected via the spi connections with all the data processed on that host PC.

    So no gpio use can require all levels of processing power post connection. It is after all designed for experimentation and prototyping.

    For my project. You clost to correct. I just use a simple GUI displays with xorg. So a pie 0 is plenty. And way lower power then the other options. It links to a pwm controller to power 2 12v 200w water tank heaters a relay for a 750w AC heater. Bluetooth connection to a BMS and solar MPPT. While operating multiple temp sensors measuring at different levels. And warning of legionaries risk. If the tank has not been over 65c in 14 days (actually 10 days but I’m over careful given the health status of my brother and I).

    So much less then the tiny Pie 0 would not be able to cope but mainly due to the need for the vision impaired interface. Speaking functions dose not take much. But doing so without being unusably slow is about the limit of a pie 0.



  • Not simple to remove. They can all be taken out.

    But the fire risk is a very valid point. All laptops should indicate they should not be left alone when charging. While many do. Setting one up in a unobserved location to run permanently should be batteryless or Lifepo4 adapted. So laptops may not be best suited to this environment. A used thin client or other DC input option may be much easier. Or an old desktop if batts and not wanted.


  • Add use of gpio to reasons to use pie.

    While gpio adaptors are available for pc. The software architecture is not as well rounded and documented.

    So for any complex hardware project development. Gpio based SBCs are often essential.

    So space, low power and gpio development.

    Otherwise yep old laptop or even desktop can be cheaper and more able.

    But overall. The wide software support and documentation for hardware connectivity is a bloody good reason to keep pie supported.

    I’m setting 2 up to control the hot water and solar dump system on my shared little boat. As I want to link 12v Lifepo4 batt charging with the solar dump and visually impaired control for AC and diesel heating of the water.

    Pies really are the best option to play with. While low power and easy to design a unique low vision interface.

    Also UK boat safty. Is issuing warning about permanently connected li ion batts on boats. So it is likely setting up a laptop to manage this while not on the boat. Will be banned in the near future.

    Only an issue for UK boating but worth considering the risks of leaving laptops to run when not observed.
