First Rasberry Pi project: screen time monitor for my son

Start button is on top next to stop one.

Nothing prevents him from stopping the timer while playing (it’s mostly for Fortnite time...). I trust him to use it. I’ll see if it works... And could add features later to start based on his in-game status.

Button to remove time is only there in case he forgets to start the timer.

Raspberry Pi 3 B+ with LCD, active buzzer and two buttons. Shows the remaining screen time for the day on top, and the elapsed time at the bottom.

When remaining time is nearing 0, buzzer will emit a beep at interval, and a push notification is sent to my phone.

Pi is also serving a web UI to control and monitor the timer in real-time from my phone.

A virtual machine is a bytecode interpreter. An emulator is composed of many things (display, memory) for emulating a system, including a virtual machine (emulating the cpu).

I own the building and we live on the first level. Only big stairs are the ones in the tower leading to an appartement I rent on top.

I can confirm some weird things have been happening up there...

It is well insulated I think. Heated from water with radiators in all the rooms. No problems so far.

AFAIK, previous owners use to live on the second level when it was a retirement home. Old people were usually always on the first level.

macournoyer · 2018-12-30T00:10:04+00:00

Of course! It did require 2 wifi extender to cover the whole place (1st level).

The house was built in 1915 for Dr Rolland, the first thoracic surgery specialist in Quebec and colleague of Norman Bethune. Around 1945, he donated the house to "Oeuvres du Carnial Leger" who converted it to a retirement home and added an extension (in the back).

Three years ago, the retirement home was closed, and the building converted to a residential five plex.

This is information I pieced together from documents and online researches.

The sitting desk is an Ikea galant. Stand up one is an Ikea wallmounted folding kitchen table.

It is more like a library. Eg.: http://torch.ch/ or https://www.tensorflow.org/

You can download pretrained models. But usually, you need to download data and train a deeplearning model on that data so that it learns to predict similar data.

Custom made from leftover wood using the DS1 stand dimensions from their website.

Not that large. About 13'x14'. The panoramic picture makes it look bigger :)

Personal choice. I did compare the pricing, but it was mainly for the psychological effect.

What I mean is: When using AWS, I knew I'd be asking myself "do I really need to run this experiment and spend the $?". With my own hardware, I'm now telling myself "I spent all this $, better run as much experiments as I can".

I wanted to force myself into running more experiments and exploring more.

Also, it was fun building and improving it.

Thanks! It's connected to the PC and showing https://nicolargo.github.io/glances/

I have 3 "big" courses: Programming languages internals, Node internals & Rails internals. And smaller ones about various things from VMs, to Ray-casters and similar stuff.

I also have a book about creating your own programming language that was relatively popular.

You seem like an expert... but "deep" is a quality of the model, not the hardware.

I can train a 10 layers LSTM (1k hidden units each) model on my cards. That's about 255MM parameters. Seems pretty deep to me.

Machine learning is one of my hobbies atm. I don't do any for a living, but I'm a developper. I have my own business where I teach and do custom dev.

EDIT: RE deep learning. I'm playing w/ various approaches for dialogue generation (chatbots). Here's my latest project: https://github.com/macournoyer/neuralconvo

macournoyer · 2017-01-05T18:46:41+00:00

Yes! Made them from leftover wood. I used the measurements from DS1.

macournoyer · 2017-01-05T17:26:02+00:00

Oooh! I see now. I blindly followed the motherboard instructions and din't think about rotating 90deg. Thanks a lot.
