Electrobloks, the interlocking DIY electronics learning kit built on PrintABloks. They add common hobby electronics components like Arduino, servos, buttons, LEDs, and others, for rapid electronics prototyping allowing you to make printablok creations that can play with you!
Electrobloks require electronics components that are then modified and inserted into the bloks. If you do not have these common components, the list below will give you suggested sources for them. But a simple starter kit like the Elegoo Uno Basic Starter Kit (Affiliate link in the PDF) will usually get you started (and there are pre-plated STLs specific to the Elegoo Uno Basic Starter Kit that you can use to get started easier) There's also pre-plated STLS for the Sparkfun's Inventor Kit (Affiliate link also in PDF) if that's more your style. https://www.sparkfun.com/products/15631
Or you can just search the parts.zip for the specific components you may have laying around. If there's a component you want to put in an Electroblok, but isn't already made, leave a comment and I'll try to add it.
Most components will simply need jumper cable leads soldered to them. So in addition to basic soldering knowledge and equipment, you’ll probably want to pick up some extra breadboard jumper wires (Affiliate link in PDF) to cut up and solder to the leads:
You would also benefit from having some basic PrintABloks on hand. At least print some extra connectors, and maybe a tall blok plate to connect things together.
Be sure to check the PDF for the complete list of components.
