Extra background information

Who has done what before

And what can we learn from it?

When I got the question to make a giant breadboard, my instinct was to open a search engine and look up what already exists. There were 2 big players online: Sparkfun, OSH Park and Hackaday

Sparkfun

The SparkFun video was not only fun to watch, but also interesting. As they are making a time lapse, you can clearly see all the materials that they used.

Pro
  • Basic materials (isomo, metal plates, wires...)
  • Clear building instructions
Con
  • Where are the giant components? Note: we found them much much later

OSH Park

During my search I found a tweet form OSH park and the fact that they made a giant breadboard that looked quite resistant to children. We looked further into it but we didn't find more info on it. We reached out on twitter, but only got info about the 555 kit and nothing about the board.
Turns out this will be look and learn documentation.

Pro
  • Clear and understandable
  • Good connections to the breadboard
Con
  • Only documentation is the twitter-tweet

Hackaday

The search also led us to the hackaday website. They have an article about a Minneapolis/St Paul based hackspace that made a giant breadboard. Sadly it only stayed at one article and some 404 links.

Pro
  • A useful picture.
Con
  • No extra information

Class info

During the class we also learned that Fiori made a giant arduino.

As we send out emails after the final presentation to thank our advisers in the industry, pretty fast we got the question if we'd keep developing the breadboard in the furture. Some changes have already been made (plexi on the kids breadboards instead of wood), but other changes will be made in the future. Therefore the latest version and updated version of the BOM can always be found in the link below.
