Has anyone created anything cool with the RP or RP2? I'm thinking about creating a couple simple automation devices for my parents for christmas..I'd like to make a home weather station for my dad who is always going fishing and doesn't always pay as much attention to the weather


Get my RP2 in from Amazon today and gonna start brainstorming

I know you can throw Kodi on one and make a decent "HTPC."

Just had a couple of them that I put XBMC on.

Oddly enough, both of them had the HDMI ports break on me right around the same time no more than 2-3 months after I got them, so I didn't bother with it after that.

But otherwise, most of my friends that have used it love it.

I've had an arduino for a few years, and the only thing I ever did with it was make an LED blink

I really need to get back into it. I've been thinking about getting an RPi + camera module to build my own security cam.




In the middle of writing this post, I went ahead and bought an RPi2, SD card, camera module, wifi dongle, power supply and dummy security camera for $107

There are cheaper wifi cameras (especially considering the time I'm going to put into this one), but none will be as flexible, upgradeable, repairable, or as fun to install as this one.

I've done several over the years. The ones I've got the most use out of have been a HTPC running Kodi, I created a smartphone controlled garage door opener/monitor, and some smartphone controlled relays to turn on Christmas lights. Some other things I've dabled in was temperature monitors for each room in my house and a snailmailbox monitor that would shoot out a text when the mail arrives. How far you can take it depends on your knowledge or willingness to learn coding. There are a few guides out there that will give you the codes they use but I've found that they still needed some tweaking for what I wanted to do.

My "pie in the sky" project I want to do is to rig up my lawn mower with some Pi controlled wheel motors, proximity sensors, and GPS tracking so I can just fire it up, click a button, and kick back on my back porch with a beer in hand as I marvel at my laziness.

They have some good projects on the official RPi site or you can check out instructables.com. They have some good stuff there for beginners.

You know you can buy an automatic mower from several different companies, right? Most are like $1k+, but still..

Still a neat project, but I would probably go all electric with a wireless charging dock. Also, for added safety (in case all your prox and other safety features fail), I would probably go with a three rotor trimmer/edger with string setup instead of a metal blade. It would still frick you up, but at least you'd still be in one piece.

I do a lot of projects with Raspberry Pis and Arduinos.



I've been using this Pi to fool around with an ESP8266 WiFi module





I use several Raspberry Pis as security cameras around the house.
I use a program called 'motion' that records video to disk when motion is detected and you can always get a live stream from port 8081.




I recently bought an 'Arduberry' which is basically an Arduino that plugs into the I/O pins of the Raspberry Pi.
You can then program the Arduberry directly from the Pi and any Arduino shields are usable as well.




This is the Arduberry by itself. The MCU is on the underside.




I have a NooElec R820T USB receiver that I use with this Pi. It (with a small antenna) can be tuned to detect radio frequency bands and I am using it to scan for nearby aircraft transponders.
I'm using that data to feed into a program called Dump1090 that will display the aircraft information on a map over port 8080.

I built a heatermeter to control my electric smoker.

I could get into that kind of project

It's a pretty easy build, was original designed for keg type smokers using a blower to control temps. So you could use it on big green eggs and their clones. I swapped the blower for a solid state relay to control my heating element.

Already phone/tablet apps for it too, so I can control my smoker/see temps from anywhere.

Not raspberry pi but I just finished an arduino and particle photon build that texts me when my dog's water bowl is empty. Just have a breadboard setup right now.

What'd you use for the enclosure? I can never find any suitable for what I need.

Next project: build a RepRap so you can print your own custom enclosures.

3D printed. Heatermeter is a completely public domain project over on the weber forum. They have all the files you need to get one 3D printed based on which RPi you use.

They have people who will build the whole thing for you. You can buy one completely built already from someone on the board or even through auberins.com. Or you can buy kits or buy every part individually. It's all up to you about how in depth you want to go with it. I used a parts list and bought everything from mouser and digikey, few items from Amazon. Had a friend 3d print the case for me.

All in all it's been one of my most useful projects.

Awesome thanks man. I figured I'd eventually have to go the 3D printing route.

My stuff came in today. I took the dummy camera apart, and it looks like it will be perfect for this. The hardest part is going to be mounting the pi camera so that it gets a good view.

Now I'll try to find time this weekend in between football to put it together.

Well, I ending up getting called into work half the weekend, so I didn't get to assemble anything. But I did get Raspbian installed, setup wifi, plugged the camera in and took some pictures. I installed 'motion' and it seems to capture motion pretty well, but I'd like to find something with a more friendly web interface to admin the camera with. Maybe this?

I plugged the Pi up to my TV when setting it up, and I was really surprised by how fast it boots, and it got me wanting to buy another to put Kodi on (among other things). I may be addicted.

This thread has motivated me to jump on board with ordering a Raspberry Pi. I have a micro-USB charger and HDMI chord, but what other peripherals are needed besides just the board in order to get it off the ground? I do not have any specific projects in mind, although I would like to be able to connect to the board from multiple devices.

You're going to need a microSD card or USB drive for storage, and a wifi dongle (unless you just want to leave an ethernet cord plugged into it).
