Miniature hydraulic quad walker

Ingo with Modell Technik Hausl in Germany built this drool-worthy quad walker. I wonder if it’s made with parts from 1:14 scale RC construction vehicles?

All I know is I want to take apart six of those construction backhoes and use the digging arms to make a hydraulic crab walker.

Arduino Tetris 4

Almost there now! What we have to do today is remove rows that are full so the game can be played and “won”. While we’re at it, we’ll add a game over sign. Previously, we got pieces to fall and collide with the rubble.

We’ve got control of our pieces. They move and they can rotate. Today we’re going to get them to fall and stop when they hit the bottom of our LED.

Wednesday’s post

I spent most of yesterday packing kits instead of writing tutorials, so today’s post is going to be around 2pm PST. Sorry for the delay!

Until then, please accept this picture of my boss to hold you over. His name is Bug.

Arduino Tetris 2

Today, we’re going to continue building on our knowledge. Last time we figured out how to get a single pixel moving around. Since we’ve got that covered, we can move on to drawing shapes and connecting pixels. Let’s get started!

In this series of posts I’m going to teach you how to build your own Arduino Tetris game using a few electronic parts from our Arduino Starter Kits. In yesterday’s post we drew a dot moving on the screen, then controlled it’s location by moving a joystick. Now that we have total pixel control we can draw shapes, and soon after that we can move them around.
