I set up OpenVPN on one and now I can Remote Desktop into my home pcs from anywhere, it's pretty comfy. I also have gitlab on another but I'm probably gonna use one pi for the OpenVPN and gitlab to consolidate. Also I'm going to use an Asus tinker board for a nextcloud set up.

I've written a code in Python for pulling weather data from yr.no to a XML file and output the next hours forecast on the display.

I have also connected three DS18B20 sensors that i got for cheap on ebay, and then written a code that alternates between the yr.no forecast and the local temperature sensors data.

Put a photoresistor and a temperature sensor on a breadboard, and made an IRC bot report the temperature inside my fridge on command and report whenever the fridge light went on automatically.

After 15 minutes, the fun was no longer there, I started regretting the whole project and started reconsidering my life choices.

Haven't used the RPi for anything since, actually.

>>62001927
To be fair, I did come up with the project idea after about 4 or 5 beers, but my reasoning was something like that, yes.

It only took me 45-60 minutes to complete (the longest time was spent writing an IRC bot from scratch actually), but yeah. It was fun to do, but the result was quite useless and stupid.

oh.

ive looked at these before seem like a huge hassle to make.

you need to get a one way mirror and either burrow a hole deep enough in the wall behind it to mount a projector or get a monitor the size of the mirror and build a housing around the mirror that will also hold the monitor right behind it.

theres actually very little you do with a raspberry pi for this project, you just have it hdmi'd to a projector/monitor running an app that shows that information.

this project is much more "build a mirror and projector/monitor contraption" rather than a "do something with a raspberry pi" project

i hate these threads because i will see people using Pi boards for overly ridicuous shit. Like using a pi board to regulate temperature or turn a fan on and off. You can do that with a pic or just a basic as attiny 8 pin chip.

3. run an IRC bouncer on your raspberry pi
4. run home assistant on your raspberry pi, hook in all your electronics in your house for a DIY smarthome
5. buy a usb ATSC tuner. Use tvheadend to create a DVR. Stream live and recorded broadcast television to any computer in your house.
6. install and configure all the automated piracy software, assuming you have network storage available for the pi to access.

Hey anons, my Raspberry Pi 3 came with a case, a see-thru RPi logo with a whole to insert and LED (which was also included).

I've connected the LED to the GPIO row, however, it isn't turning on. I've tried connecting it in various different ways.

What must I do to get this simple LED on? I'd like for it to turn on whenever the Pi is on and have it be a stable red color. Thanks.

>>62005276

>>62005276
#1. For the protection of your Pi, stop shoving components into random holes. Some of those are hot and you could legitimately damage the pi.

#2. Stick the anode in a GPIO pin slot and stick the cathode to ground.

Then run the following commands as root.

> Register the pin. Replace $NUMBER with whatever pin you have the anode in. Pic attached for numbering.

# echo $NUMBER > /sys/class/gpio/export

> We are looking to push data OUT on the pin, not read data from the pin. So we put it in "out" mode

# echo out > /sys/class/gpio/gpio$NUMBER/direction

> Turn it on and off

# while /bin/true; do echo 1 > /sys/class/gpio/gpio$NUMBER/value ; sleep 1; echo 0 > /sys/class/gpio/gpio$NUMBER/value ; done

I can't. The LED it came already has its 2 wires connected together with a 2-holed part that allows me to stick it into the GPIO pins (see pic).

>>62005392
Can I do that if my LED came connected like pic related?

Trying home automation. Bought some sockets which work on the 433MHz RF, but the receiver on the PI doesn't register any signals from the socket remote control when I press buttons, so I'm getting nowhere fast.

>>62005528
Yeah, you can bridge wherever a GPIO pin and GND pin are across from eachother.

So
> 5-6
> 13-14
> 19-20
> 25-26
> 29-30
> 33-34
> 39-40

See how they have those alternate functions? If you didn't play with device tree files, your Pi probably isn't configured to use them. That being said, Just use 13-14, it doesn't have any possible conflicts.

Make sure that you know which one is the ANODE and which one is the CATHODE. diodes only pass current in one direction, and LEDs are "light-emitting" diodes. In other words, if you flip them, you won't get blinks.

now you're getting it - but, at the end of the day, gpios are software controlled, so what ever you di its not going to be universal and will require a bit of coding and replication every time you reinstall, which is why I originally suggested pins 1 + 6, 3.3v and ground - that way whenever there is power to the board, led will be on, regardless of software.

now, unless what you've got isn't really a pi case - the led is designed to plug in SOMEWHERE, and since its two fixed adjacent pins, and ones of them must be ground - 4 + 6 is the other place, but, and its a big but, 5v is pretty damn high for an led, especially a red one - if its designed to go somewhere and work without any software, thats the place tho.

This is a really sick component, thanks for the link.

I feel obliged to bring up that you should be a good citizen and be aware of FCC regulations whenever you start playing with radio. You have nothing to worry about because these things are so low-powered that you're not going to get caught or in trouble, but as a ham I just want to bring it up. This page should give you all the information you need, assuming you're in the USA: http://www.arrl.org/part-15-radio-frequency-devices

With that out of the way, let's go back to your original post.

> Trying home automation. Bought some sockets which work on the 433MHz RF, but the receiver on the PI doesn't register any signals from the socket remote control when I press buttons, so I'm getting nowhere fast.

Take a step back. The goal of this is for a signal to go through the air, transmitted by the remote. This receiver then does a lot of hard work. It filters, downconverts, and demodulates the signal and puts 1's and 0's out on the data pin.

Starting from the top of this chain, here are some debugging steps:
1. Be sure that the remote is actually transmitting. Assuming you can control the outlets with the remote, this is a given. If you have access to software defined radio, look at the signals in gqrx or sdr#
2. Be sure that the component is connected properly, specifically be sure that you're giving it enough power. Cheap ATX power supplies with a $10 dangerous prototypes breakout board is the best. If you don't have something like this available, at least be sure that you're giving the pi 5v2a.
3. A scope / logic analyzer would be super useful in sniffing the pins and making sure you see something moving into the Pi.

Assuming the physical side of everything seems correct after a double check, we should focus on the software. It may be the case that the data is coming in too fast for the Pi to handle. What are you using to read packets?

>>62006897
https://github.com/milaq/rpi-rf/tree/master/rpi_rf is linked in the video you posted. I would download this and try to use it to dump traffic.

$ mkdir rfstuff && cd rfstuff && python3 -m venv venv && source venv/bin/activate
$ pip install rpi-rf
$ rpi-rf_receive -g $PIN_INDEX

Also, just to be clear, the $PIN_INDEX referenced here (and in sysfs) is not the pin index 1-40, it's the "GPIO X" index in orange in >>62005402

Assuming you can't get this to work after double checking, my guess on problem points would be as follows:

1. Power supply issues, data isn't coming into the Pi
2. data coming in to the pi, but it's too fast or something

I liked pi-hole's implementation so much I virtualized it. First I ran it on pi but thought that it's kinda wasteful to have a pi to just act as a dns sinkhole so I moved it to my virtualization server.

I use pi's for irc clients and as a remote desktop thin clients at work. I plan to set up one as a temperature/humidity logger, just havent gotten around to it yet.
