I'm very likely receiving a box of 10 computers soon. Maybe this week. My teenage self would be absolutely thrilled and I'm feeling pretty good about it.

I ordered some Mango Pi Mq Pro to try and run some Nerves workshoppy hack things with the local prospective Elixirists.

Just might get them in time for the January meet.

@fhunleth any recommendations. I'm thinking starting at Nerves Livebook with some extra libraries packed in (evision for example).

Maybe this? https://github.com/wojtekmach/mix_install_examples/blob/main/phoenix_live_view.exs

@lawik If you're looking for hardware ideas, many RPi hats work with the MangoPi. The MangoPi's built-in LED is attached to a PWM output, so it's a little more fun to control. See https://github.com/smartrent/delux. If you can't do something with Nerves Livebook, let me know so I can add it.

@fhunleth evision and Phoenix don't ship with it do they?
Show threadFrank HunlethDec 29, 2022
@lawik Livebook pulls in Phoenix, so Phoenix and a bunch of Phoenix libraries are available. Evision isn't included. It could be included, though. It's a large library so I was wanting to know whether it worked well enough on the devices to be useful.

@lawik Nerves is good for hardware toys. You can play with evision on a big computer. With nerves is more fun to connect some wires. Example: everything that has i2c should work and if it's not out of the box and if not it's even better because you can make the library for it.

@dkuku @fhunleth Thanks. I'm pretty well aware of what it can do though.

I want to start pretty focused on the board and what can be done without adding more hardware. Partially for practical reasons.

If the interest is good I might just order 10 breadboards, bunch of components and cables and some fun peripheral stuff. Do more sessions with the group.
Evision would let people experiment on a picture taken with their phone and then use it in Livebook :)

@fhunleth I'll likely give it a try when I get them then :)

@fhunleth didn't realize the pins were so compatible. Is it 1-to-1 mostly?
Show threadFrank HunlethDec 29, 2022
@lawik It depends on the hat. It's close, but you need to check and GPIO numbers are different.

@fhunleth Thanks, figured there would be differences

@lawik I have two Raspberry Pi Pico and a bunch of electronics stuff laying around for a week now. Plan is to do some microcontroller action and use them as sensors for some poor mans smart home stuff. The central brain will of course be @NervesProject driven.
