OpenRC Tractor toy model 2

Well, it is not actually RC controlled, it’s a replica of a replica! Video with the real OpenRC tractor HERE

Since I released my OpenRC Tractor, I always wanted to design a smaller version (not radio-controlled). And now it’s finally here! A toy tractor, easy to print and very cool!

My Arduino project

After a couple of weeks working with Arduino and learning how to use different components, it’s time you think about something cool to do with it. It really is up to you, as you can choose any project you like as long as we have all the needed materials.  Be […]

Impossible dovetail puzzle

I wanted to challenge my nephews and nieces for Christmas. While searching the Internet, I stumbled on Clickspring machined impossible dovetail puzzle on Youtube. It is an amazing job and I decided to design one myself. Taking it as an inspiration, I modified it a little and added some extras to make it more challenging.

OpenRC Tractor Cultivator

After a few months, it was about time to release a new OpenRC tractor tool. In this case it’s a spring loaded cultivator. It levels the surface of soil to prepare a perfect seed-bed. As it is spring loaded, it’s suitable for use in stone and root obstructed soil. If one tine strikes a hidden object, the others will continue working at the correct depth.

Encoder and servo 6

In this activity you’ll learn how to control a servomotor with an encoder. A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to an analog or digital signal.



Seven segment display 4

In this activity you’ll learn how to show something on a seven segment display. In order to make it easier to use the display, we’ll use a library. 

Temp and hum sensor 3

In this activity you’ll read the ambient temperature and humidity with a DHT11 sensor brick. In order to use the sensor, you’ll need a library. Libraries provide extra functionality for use in sketches, e.g. working with hardware or manipulating data.



PIR sensor 3

In this activity you’ll learn how the PIR sensors work. A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. We’ll use it to turn a led on or off.
