    Waste of time or good idea?
    Perfectly doable, I've done basic tests with an SSD USB3 drive, transcoded 264 and 265 fine.

    Don't do that, they're overpriced and underpowered.

    Nice one. Cheers.

    I started playing around with a Raspberry Pi Pico with the aim of building an automated watering system for our potted lemon tree.

    Fucking Hell did I NOT have a clue what I was getting into. But now, two weeks later all I need is my replacement moisture sensor to arrive and I'm ready to put it all together.

    I've learned so much these past couple of weeks, bit of Python, some circuitry, that it's a great idea to put a resistor infront of an LED.

    Also some irritating finds, like how my Powerbank can't be used to power the Pi Pico because the pico draws so little energy that the powerbank will switch off.

    But as a hobby I can definitely recommend getting into this DIY automation stuff.

    Okay, so I know very little about these things, but I want one which will work as a retro gaming thing and a media box - is that possible?

    Basically something that I have stuck behind my telly so I don't have to fuck about plugging my laptop in everytime I want to play or watch something.

    I've seen premade kits that comes with tiny NES cases. They're all small enough to hang behind the TV.

    I've only got links for swedish shops though, but I'm sure you can find them elsewhere.

    @BreadBinLidHero

    Certainly possible, but I'm not 100% on switching between using it as a retro games machine and media player... There will probably be some element of faff involved in switching between the two use cases. A quick search for "retropi and kodi" sounds like the easiest option.

    For retro gaming there are loads of pre-build SD card images out there of varying sizes to accommodate different sized SD cards. Just download, use the Raspberry Pi imager to write it to the SD card and then plug it all in and away you go.

    Adhesive velcro tabs and stick it to the back of your telly, job done.

    Yeah, should be able to have 2 SD cards that you swap in and out...

    Thanks folks. One Pi and two cards seems easy enough.

    Given the DIY nature of it, shouldn't there be a way to add an extra SD card reader, or creating a boot screen that let you decide if you want to game or watch stuff?

    I read there's an IR blaster you can add, so maybe that's an IR receiver as well?

    @Tonka
    It should support HDMI CEC so can be controlled with any modern TV's remote, so no real need to faff about with that unless you need something specific out of it.

    There should be a few options, bit switching SD cards or using Kodi within Retropi are probably going to involve the least fucking about figuring stuff out.

    I have a small veg garden in a raised bed, and I have had this exact idea before. I even got as far as routing in the irrigation system to each square.

    Have you got any notes collected anywhere you could share? Or links to similar projects. Might try and do it over the summer

    @Benno there's plenty on YouTube. My project is in limbo at the moment because my moisture sensor was busted and the replacement is on the way.

    But what I've learned so far (that I had no idea, didn't think of, coming in) is
    * I needed a Relay module where the stronger current for the pump will be controlled without frying my Pi Pico
    * I needed a powersource for the pump (that is now plugged into the relay module)
    * I need another powersource for the Pi Pico and my PowerBank wouldn't do because that cuts off automatically when the power draw is as low as the one that the Pi Pico needs
    * I need to mount all my hobby wiring on something and then put it in some box

    But, the coding is very straight forward and I have really enjoyed the whole learning experience. I will probably end up buying a soldering iron and a through hole circuit board to put it all on

    @Benno I also just found out that a lot of the capacitive soil moisture sensors have a flaw, but that the flaw is easily fixed

    As can be seen here: https://www.youtube.com/watch?v=QGCrtXf8YSs

    Still, that capacitive sensor is the way to go. The two pronged versions corrode and stop working really quick apparently.

    You can fix this by adding more RGB to your build.

    FYI I installed Kodi on a Pi that also had Retropie on it and found the process easy enough, there's a dedicated option in the config screens. However you should be aware that Kodi is basically your only option in this circumstance and there are much better options if you wanted a legit streaming box

    @brokenkey Not bad actually. I do have a tiny LCD screen that I thought was unnecessary for the project. Maybe if I leave that on at all times it would draw enough to keep the juice flowing.

    @Psiloc and for a less legit streaming box?! Uses to use Kodi quite a bit but not anymore. Became too much of a faff

    Same, like getting YT on it involved a third party add-on and it was entirely list based and very flaky.

    Good for local media or media server access, and the "other" stuff of course, but it's no smart device.
