Cheap Arduino Robot with everything you need

I see a growing number of companies marketing Arduino based robots for well over $100 a piece. Most of these bots have limited capability and still utilize the Arduino IDE for programming. I needed a simple programming platform for my IT students, so I designed and built my own robot to save money. If you are willing to purchase components from Ali Express this is the robot for you. I have attached complete build instructions and Curriculum and .stl files will be on there way soon.

BC Tech Ed course outlines 2016

Attached are some course outlines that my students use at the grade 8-9 Level. as more grades are completed I will do more updates. Note these are meant to be a guide and will most likely not be the final version.

Shut the Box Up

Shut the Box Up is a great one or two player game. These instructions will help guide you to build this game with minimal hardware. The  game can be built with 9-12 pieces these instructions are made to help guide you in your build.
   


Instructions to build Shut the box up

the object of the game is roll 2 dice cubes and flip up all the numbers. for example, if you roll a

1 + 6
you can flip up the 1 and 6 or the 7 only.

if all the numbers are up, your score is 0 and you win.  If the only number left is 8 and you roll a 3 your final score is 8 the goal is to get the lowest score possible.

Quattro!!!

Quattro is a mathematical game with the objective to make  4 in a row by using the 16 unique game pieces.

these plans are a guide to build the game board, a stylish box, and the 16 individual game pieces. Because each shop is different and your tools may very, the exact details on how to do each operation are left out.



find the plans here

please provide comments if there is a problem or you require more information.

Quattro is played on a 4×4 board. There are 16 unique pieces, each of which is either:
  • tall or short;
  • red or blue (or a different pair of colors, e.g. light- or dark-stained wood);
  • square or circular; and
  • hollow-top or solid-top.
Players take turns choosing a piece which the other player must then place on the board. A player wins by placing a piece on the board which forms a horizontal, vertical, or diagonal row of four pieces, all of which have a common attribute (all short, all circular, etc.). A variant rule included in many editions gives a second way to win by placing four matching pieces in a 2x2 square.
Quarto is distinctive in that there is only one set of common pieces, rather than a set for one player and a different set for the other. It is therefore an impartial game

123DCircuits and Digispark for Easy Cheap Projects





I have been working with ATTINY chips for some time. When I saw the low cost Digispark that has one on board, I had have 1.

 I have developed this project that utilizes the ease of programming with 123D Circuits and the cost of digispark. It is very similar to the standalone ATTINY circuits posted several years ago but has been simplified, to make it easier to program and easier to manufacture. Check out the instructions bellow.

Autodesk Inventor and the 3D Printed Car

I have had students using Autodesk Inventor and Slic3r to design cars for awhile now. Students can design cars both with moving wheels and stationary. the cars are very easy to design, a 12 year old student has no problem going through the tutorial and producing the stationary wheel car in about an hour. As far as learning goes this project exposes students to a wide range of 3D modeling and printing techniques. Prior to designing the cars in Inventor teachers could go through the design process with the students and have them design their car around a given brief, or just let them have some fun with it. In order to differentiate the instruction of this project as much as possible I have made a written/picture tutorial and a video tutorial.
