Win a Raspberry Pi 4 in Celebration of Our 10th Birthday!

The new Pi includes many new features but the one that excites me the most is the dual HDMI displays.   I would like to use it to build a dual user gaming system.  Where each user has their own monitor allowing us to compete against each other in a game like Battleship.  Alternatively to play a collaborative game  where each player performs a different function to accomplish a goal, such as the pilot and weapons officer in a combat game.

I hear that the new Raspberry Pi 4 is supposed to be a viable desktop replacement, so I would like to make a custom laptop.  I'd 3D print the body and use a bunch of 18650 batteries.  One of the HDMI ports would drive the display (which I haven't chosen yet), and the other HDMI port would be available externally to drive an external monitor.  The ethernet and the two USB 3 ports would be available externally, but I'd probably hook up some kind of USB hub to at least one of the USB 2 ports, because I've always wanted more USB ports on the laptops I've owned.  I'd provide for some kind of external external access to the pin header, so that I could control various hardware gadgets.  It would definitely have a keyboard, but I'm not sure it would have a trackpad - I'd prefer an external wireless mouse that somehow inserts into the case to get recharged.

I'd like to use the new RPi 4 as a "kitchen computer": one HDMI connected to a monitor on my desk in the kitchen, and the other HDMI connected to a TV mounted above the working space in the kitchen, then, will wait for voice commands to come in via Alexa (or voice recognition running on the Pi itself). Example commands: "show bread recipe" to display the requested info on the TV, "play my music in the kitchen" to play my music via the TV's speakers, "play my music on the desk" to play music via the speakers on my desk, or "show pictures in the background" to run a slideshow of all my family photos on both screens at once.

I would use the Raspberry Pi to monitor the water volume in my rain water Butt and to control the irrigation pump to prevent the flower bed's irrigation pump coming on when insufficient water is covering the immersed pump. Also, the Raspberry Pi would sense if it was raining and inhibit the pump to prevent waste of water.  Environmental conditions such as air temperature, black bulb temperature, air humidity, wind speed and water temperature would also be monitored and used to decide as to how long each irrigation session was scheduled.  Soil conditions would also be monitored to see how damp the soil actually is and as to whether irrigation would be required.  All sensor values and water flow volumes (for each session) would be recorded every 5 minutes and stored in a data base file for use at a later date.  This would be a "Skill" learned by Alexa so that I could interrogate the system from anywhere in the world.

My plans for the Raspberry Pi are, to have a home server that performs the following functions:

OpenVPN server

Apache in house web server to provide stats on the Pi's health

A junk call blocker using JCBlock public domain software

A surveillance system using Motion software or a Time Lapse camera

And finally Samba do I can share files with my PC.

I'd leverage the new Pi 4 to be the brains of autonomous rovers guided via Tensor Flow models.

My daughter and I are back the interested in building a variety of projects, but she is pulling me towards some kind of robotics

I’m just starting out with a Pi so I would like to make either autonomous flying drone or a smart mirror.

I would build out two things. One is a Morse Code device that I will hook to my HAM radio. The Pi will receive and translate Morse Code signals and do the reverse when I send text to the Pi. Secondly, I want to set up an automated investment management system for crypto currency. The system would receive pricing and trending information, hold buy/sell orders, and automatically execute the orders when the criteria are met. This would require a display of course, but I think the hard art will be setting u interfaces to data streams … APIs to scoop data from an exchange.

I'll finally finish my arcade emulator+media streamer project. The old-school arcade is almost ready. But my Raspberry Pi 1 model A is a little too outdated for the job...
