Beginner’s Method for solving a Rubik’s Cube – Ritger

With 350 million puzzles sold, practically everyone has at one point in their life either played with or owned a Rubik’s Cube. Invented in 1974 by Hungarian mathematician ErnÅ‘ Rubik, the puzzle has over 43 quintillion unique combinations. The popularity of the Rubik’s Cube really took off in the 80s and is still one of the most popular puzzles to date.

This workshop teaches the Beginner’s Method for solving a Rubik’s Cube. The Beginner’s Method requires more turns than other ways of solving a Cube but is a lot easier to get started with and memorize.

When deciding whether this workshop is for you, keep the following in mind:

– Are you not satisfied with the amount of noise made by your fidget spinner? Try a Rubik’s Cube!
– Do you have the spatial awareness of a drunk monkey (or better)? You may like a Rubik’s Cube!
– Is there absolutely nothing else to do? Come solve a Rubik’s Cube!
– Do you want to be able to show off your intellectual prowess by solving a puzzle made for an eight-year-old? Let’s do it!
– Would you like to relax by taking some time for yourself in a room with 20 strangers and solving a cool puzzle? This is it!
– Are you looking for things to throw at people’s heads? Please find something else, as there are only 25 cubes available…

This workshop houses 20 participants (or more, if you’re quiet). Cubes and instructions are provided and someone is on-hand to provide you with some help if you need it.

So come relive how it was to be a kid in the 80s and revel in the glory that is the Rubik’s Cube.

This workshop is organized by ritger, a member of Hack42, the Arnhem (NL) based hackerspace.

Blacksmith Workshop (SparkShack @ HackerHotel) – Gori

Blacksmiths are the original proto-hackers: makers of tools and machines, enablers of civilization. The craft has been around for at least 7000 years, and it is still going strong. This year at hacker hotel, you will have the chance to try it out for yourself! SparkShack, the metal workshop located at RevSpace in The Hague will be present, with an array of materials and tools, providing demonstrations and workshops on steel forging and aluminium casting. If there is interest and we all feel like it, we wil do more advanced things, like pattern-welding steel to make damascus, etching and staining steel, forging aluminium or casting copper and bronze.

The following activities are planned :

  • Forging and casting demos! Times will be announced at the event.
  • Ask Gori for a introduction to forging workshop. It takes about 1 hour, two persons max. Times are random and flexible
  • Have your custom 3D printed design cast in metal! Contact beforehand if you want to do this.
  • Come and play with us anytime the workshop is open!

Most important thing is that if you want to play at the SparkShack, please bring protective clothing. Red hot steel and molten aluminum are very dangerous and can seriously hurt you!
This means :

  • Closed leather shoes
  • Safety overall or jeans and thick cotton shirt
  • Safety glasses
  • Leather gloves
  • Ear protection

Absolutely no synthetic clothing! Synthetics can catch fire and will melt onto your skin!

SparkShack @ HackerHotel is organized by Gori, a scientist and dad by day, hacker and blacksmith at night.

“Introduction to LoRa” workshop
(2 workshops – Saturday Morning)
Thomas Renes – Niels Ardts

This workshop will give an introduction to LoRa.
It starts off with a small presentation what LoRa is, how it works and what it can be used for.
There are a few Arduino boards available with Built-in LoRa chips which the participants can use. The participants can try to send sensor data over the LoRa network to the op The Things Network. We want to make people interested in LoRa, so our target group is people that haven’t done anything with LoRa before.

Participants to this workshop must bring their own laptop, we bring the LoRa gateway for LoRa coverage. We have 10 Arduino boards with builtin LoRa chips, so we can host 10 people per workshop. Each workshop lasts 1,5 hours.

The workshop leaders:

As Lead Cloud Architect Niels Ardts is responsible for the entire infrastructure of Intermax. He makes sure our infrastructure is working 24/7, without any trouble or interruptions. Also, he ensures that our infrastructure continuously meets our needs. Last but not least, Niels is essential for the constant flow of innovation within our company, always trying to figure out ways in which IT can make our work easier.

Thomas Renes works as a Security Engineer for Guardian360, where he works on making the internet a safer place. As a cyber security-specialist his daily life revolves around finding vulnerabilities in code and machines and making sure that these vulnerabilities cannot be used by malicious individuals. Thomas is also interested in the internet of things and home automation, especially in combination with security.
