Bought a 3D printer!

Finally I bought a 3D printer – an almost complete kit for popular Creality Ender 3.

It happened to be a decent printer that produces fairly quality prints.

Some test prints:

Some things I tried to model:

Created a new instagram account and post stuff related to 3d-printing and general DIY: @shu.makes

The journey continues!

TicTacToe as a coding test task

One of my most fun interviews was with DI.FM in 2018.

On the coding lab I was asked to make a tic-tac-toe game in one hour.
I was later given some time to refine it afterwards, but the core thing was done in time and it was interesting.

Play with someone.

Repurposed an old iPad as a home status screen

Here is my new small project – TableStatus/StenGazeta (Daybook.buznik.family as of November 2020).

I have been thinking about creating some kind of a status screen for my home and family for a long time.

Our friends have recently donated an old iPad 2 to us. It runs iOS 9.3.5, so I can barely install a handful of apps from Appstore. That’s where this idea started.

I could never gather all the details until this Christmas, when I got some time and slapped together a preact web app.

Demo

Features

It’s a web page that displays widgets:

  • daily weather – temperature, conditions and humidity, and lunar phase
  • agenda – events from our shared calendar for the day (events are also togglable, so you can use it as wishlist)
  • photoslider with pictures from selected google photos albums
  • simple notes

Nothing particularly interesting about those – mostly leveraging a couple of APIs.
I used openweathermap.org for weather, and Google APIs to retrieve the calendar and photos.

The notes are just a text area that stores value in localStorage, not synced across sessions.

Usage

You can just visit Daybook page on your iPad and it will work.

In order for Calendars and Photos to work, you need to login with your Google account.

Source and Setting Up

Right now, I’m happy with the result, though I’m adding some ideas as enchancements on Github.

Source code on Github

It has a readme which has some notes on the API keys that you need to get and some other vars to set up.

The project is build with webpack and can be hosted on any kind of hosting. I use Netlify for it.

You can set up one for youself, too.

Anyway, let me know if you’d like to use it, but it lacks something via this form.

A note to React gurus and beginners

The project is definitely not to show off my React skills, rather the opposite – I wanted to slap some stuff together in a very limited timeframe and also to try preact.

Also if you are a beginner and want to learn by its code – it’s not the best specimen.

preact

I wanted to go really minimal and was lured by preact’s promise of 3kb gzipped size.

However I ended using the preact CLI to create the project boilerplate together will the webpack and compilers and other stuff, and 260Mb node_modules.

Also tried to start with React Native, but its toolchain is still not clear to me. Ran into a couple of issues with the suggested solutions as “reinstall all your node_modules and cocoa pods”, not cool.

diPlayer – Raspberry Pi-based player for DI.FM

This is a desktop player for DI.FM that I made for the 20-year anniversary.

I gathered a lof of experience during this proejct:

  • learned how to solder (again)
  • familliarised myself with Python
  • wrote and debugged firmware for an Arduino Nano
  • learned to model in Fusion 360
  • found out that 3-d printing don’t happen right on the first time

Details

Desktop player based on Raspberry Pi, that can play DI.FM channels (IceCast streams to be exact).

It is controlled with photoslides frames that have NFC-stickers on them, the stickers point to certain channels.

The player can also play other sources like Spotify, Google Play Music, Soma.fm thanks to MusicBox software.

It has a physical Play/Pause button, volume knob and a small screen that displays current track. Sound output is through audiojack or HDMI (Raspberry Pi standard).
