Cool projects to do with raspberry pi 3?

My goddaughter is 8 and just finishing up the school year. I thought it'd be cool to do some cool projects with her over the summer. Anything Sup Forums recommends? She's into minecraft, but I know nothing about it.

tell her shes a faggot and give her some meth

Will coke do?

Stick it up her ass.

Turn it into a colon exploration device.

make a little minecraft themed robot/automated thing and teach her to program it.

Arduinos or even better ESP8266 / ESP32 are much better for this.

8 is pretty young for programming, but you can build some console with emulation station and buttons and a display?

I use arm dev boards for servers, so maybe I just lack imagination.

How difficult is it to Google?

Pretty much this:
Also: There is Minecraft: Pi Edition you can add or Armagettron

sorry i meant this

automatic porn crawler and archiver.

I wish I knew how to do this...

Is it like a python script or what
How does it work

Yeah, crawl through porn sites with BeautifulSoup, save the video, open all related or just go through each category.

To save videos you'll probably want something with Gbit ethernet though. And maybe a SATA port.

I have a ryzen 1700 server at my disposal, just not smart enough to build all l this from scratch

Hijacking the thread with a related question:

I'm a mechanic who knows very little about electronics, would something like a raspi be usable as an ECU?

It would need to be able to receive inputs from (at least) a camshaft angle sensor, manifold air pressure sensor, air intake temperature sensor, throttle position sensor, wideband oxygen sensor, coolant temp sensor, and a knock sensor or two.

Outputs would be 4 fuel injectors, 4 ignition coil packs, and some kind of information display.

I know there's products like Megasquirt on the market, but I figure this would be a good way to learn how to do it myself.

Call me when those things have separate usb and net connections. The only use i have for one of them is nextcloud and similar shit, but i will not tolerate shared bandwidth.

>She's into minecraft

she's doomed. give up on her and move on

Probably. You may want to look at a microcontroller instead for faster responses from the sensors and hardware interrupts, but your biggest issue is supplying it with constant, level voltage. Cars are a pretty bad environment for low voltage devices because they can easily surge up to 20V or more, so you need to run it through something to manage the voltage.

for the inputs if all this sensors are 3v3 or 5v you will be fine, if lower or higher you will need extra stuff, either DIY or you can buy them it depends.

For the output same thing goes, but most likely you will need some kind of driver motors or something and an external powersupply for the ignition coil packs(whatever htat is, but the max output rpi3 can get is 5v at around 1A and it fails if it doesnt have at least 1.5A going to it. so 2.5A powersupply for the RPI3 alone is mandatory)

It is quite possible, but I think you are better off with some industrial grade arduino or something that can be powered with variety of ways and can output better stuff. It wont hurt to try and prototype, learn in the process and eventually do something professional. We are talking around $ 100 down the shitter for a lot of experience in exchange if you are all up for this - go for it, if you lack money/time and cannot experiment for too long, go ask an expert and don't waste your time.

> Cars are a pretty bad environment for low voltage devices because they can easily surge up to 20V or more
The highest I've seen any car hit was 16 volts, and that was because the 12v sense wire for the alternator was unplugged, forcing it to run at maximum output. The battery acts as a buffer for voltage fluctuations, or so I've been told. Normal operation is between 13.7 to 14.4v on the majority of cars I've worked on.

That kind of spike would kill pretty much any car's electronics made in the last decade or so anyway, and most have been running electronic fuel injection since the mid-80s without issue. New shit is pretty delicate.

>for the inputs if all this sensors are 3v3 or 5v you will be fine
Pretty sure that most of the resistance-type sensors run between 1-5v, the others are usually inductive sensors that put out something like 1-2v.

As for cost, $100 is peanuts compared to an aftermarket ECU, even a secondhand unit can cost upwards of $500 without an accompanying wiring loom, so that's definitely a bonus.

I'm honestly not sure what kind of amperage a coil pack draws, but they typically step up the 12v battery voltage to 20,000+ volts. If the ignition side of things is too difficult I can always run a mechanical distributor instead - the main advantage of EFI is being able to control fuel flow, and that basically just involves switching solenoids on and off very quickly.

Thanks for the replies.

IOT door stopper

I was wondering would it be possible to build a 3d printer with a pi. I have an old printer i cna slavage servo motors and stuff. All the tutorials online are about using audrinos. I want to fully control the printer with a pi

Help her build an IR camera for her bedroom window or in a garden and get her interested in nature and astrology. Then stream the camera to a computer overnight recording and play it back for her.

Or take it to a preserve and tape it to a tree and see what comes investigating.

Buy a case that makes it look like a brown brick

>but I figure this would be a good way to learn how to do it myself.

It's not as easy as you probably think, but if you want to learn something, there are better ways out there than a Raspberry PI. A AVR would be a good way to start (I would recommend a 8 bit type which you program in assembler, you don't need hundreds or thousands of Mhz if you are smart), also get yourself a oscilloscope, a multimeter and time... much time.

As a mechanic you already know what are the essentials to get the engine running, but how much do you know about electronics/programming/hardware?

btw. about what timeframe you are talking?
