  1. Multicopter Megathread

    Time for an upgrade to hall effect gimbals?
  2. Multicopter Megathread

    Yeah I'm in the CBD, on that group already and do keep an eye out, I'm just not sure how often I would be able to get out and fly a 5" and don't see much smaller stuff 2nd hand
  3. Multicopter Megathread

    Yeah, is that the rotorcross one? I have been keeping an eye on that for a little while
  4. Multicopter Megathread

    Yeah it's far from perfect but for NZ$50 (about $35 US) and a bit of soldering you can't expect much better, to take the next jump I'm looking at spending easy 4x that on TX and a battery charger before I even buy a quad so at least now I own goggles it separates that cost and I can enjoy them while I save for the next bit of kit
  5. Multicopter Megathread

    Yeah one thing I hadn't considered was that adding fpv cut my flight times down to about 1 minute. But for 1/5 the flight time I have 1000X the fun so I think it balances out
  6. Multicopter Megathread

    Just joined the FPV master race! 😁 It probably Show's but I'm on a fairly tight budget and also live in the middle of a city so a full 5inch build isn't really on the cards but I do want to build a 110ish brushless when I have a bit more cash in the bank. Anyway just though I would stop in and introduce myself 👋
  7. USB Raspberry PI proximity sensor?

    If you are worried about soldering you could get a PIR sensor on a board with pins and use F-F jumper wires to connect it to your PI

    The Arduino will power off a 12v source, although you are probably better getting something to Step down the voltage to 9v as 12v is the top end of what they can handle.
  9. Motorized Door Lock Help

    Correct however you could use one relay and have it going live trigger a change of state, so in sudo code: If door = locked & button = pressed Unlock door Else if door = unlocked & button = pressed Lock door There are a lot of beginner tutorials that show pressing a push to make switch turning an led on and off, that code could easily be adapted for your needs
  10. Motorized Door Lock Help

    This page on the Arduino website is a good place to help you with the very first few things you need to do. Then if you look up Jeremy Blum on YouTube he has quite a good set of beginners tutorials.

    Servos use PWM signal inputs to represent a position the servo should be in. So if you are trying to have button a = locked and button b = open you would need button a to send the PWM signal representing 0° and button b send the PWM signal for 180° (or whatever values give the range of movement you need) This Article gives a brief overview of how servos work. The second item you have linked seems to be a relay box of some kind although looking at the listing I'm struggling to understand exactly how it functions but I don't think you could use it to control a servo directly. However if the A and B on the remote are closing two relay circuits you could use an Arduino to detect when one of those relays are closed and then send a PWM signal to your servo either locking or unlocking it I hope this helps
  12. Getting started

    Don't be expecting quality but This corner of banggood is a great place to find some cheap practice just keep an eye out for listings in good English or that show the instructions so you can check they make sense.
  13. My Not So Private Network

    Thank you! That was exactly the missing link I was struggling with I was thinking something along those lines, I could always just connect directly to use Skype and Netflix without the VPN Thanks again for your help 😁
  14. My Not So Private Network

    I have just moved apartment and in my old place I had a very simple network setup of a modem\router serving wifi for most of our devices and a raspberry pi connected by Ethernet serving as network storage, basic server type stuff and as a box for me to ssh into and just generally play around with. Now in my new apartment building there are a series of wifi hotspots spread out through the building that I have to use for my internet connection with the one closest to me only giving good coverage to about 75% of my apartment. So what I am trying to do is connect into that hotspot (login via captive portal) then share that connection into my own private network set up in a similar way to how I had before, with the aim being to give wifi coverage to my whole apartment and also to be able to host network storage that other people connecting to the hotspot can't see Also as a bonus I wouldn't mind being able to rout all my internet traffic through a VPN Can any of you Network gurus help me or point in the right direction? Any kind of help would be very much appreciated as I am at a total loss

    Could you broadcast on a carrier wave from the tower then decode and stream it from a location with a broadband connection? If not with some tweaking I think you could get ffmpeg on a raspberry pi streaming at quite a low rate as a low cost / low power solution. This digikey article gives an example of streaming to YouTube or Facebook. Also it might be an idea to check your cell carriers terms of use as they might take offence to a near 100% uploading connection
