I adopted a cat a couple of weeks ago (Figure 2&3). To celebrate, I wanted to make a cat whisker sensory extension puppet that looks like my cat! This project will show you how to create a computationally enriched puppet that has whiskers. The Puppet (who I call Mr. Bits) has four flex sensors attached […]

In this tutorial, I’ll show you how to use a wireless PlayStation 2 (PS2) controller and an Arduino Uno pilot a robotic tank. Story An Arduino Uno board was used at the core of this project. It receives commands from the wireless controller and sets the speed of the motors. Other development boards might also […]

If you’ve ever looked at prices for prosthetic hand, you may have noticed that they can cost upwards of $5000, with more advanced myoelectric controlled arms priced at over $20,000. Such prices are not ideal considering that over 80 percent of amputees are from developing countries where access to prosthetic limbs is limited by lack […]

In this tutorial, I am going to show you guys how to control the TM1637 4-Digit 7-Segment displays using an Arduino. If you want to displays sensor data, temperature and humidity, or want to design a clock, timer or counter, you will need this 4-Digit Seven-Segment Display.  Step 1: Topics Covered In this tutorial […]

If your IT systems are completely or partially managed by an external managed service provider (MSP), then you should see a boost in your company’s performance and a reduction in annual expenses, as compared to statistical data from before. If none of that seems familiar, then that in itself should be the first red flag. […]

In this tutorial we are going to show you how to make an interactive sound wave print within a picture frame, so you can see and hear your favourite song at the same time! When you touch the print through the glass of the frame, it will play the song shown in the sound wave […]

I always wanted to make a PCB and this is my first professional circuit board attempt. So before you decide to start this project you should know there could be some mistakes or it could be more reliable and compact. This design is not the most efficient and cheapest way to make a DIY MPPT […]

Follow the instructions below to build the remote control car. This project is ideal for science fair, robotics competition and university projects. The design is highly adaptable, you can modify it easily and add your own components. Table of contents Step 1: video demo Step 2: circuit diagram Step 3: Arduino code (software) Step 4: […]

Ever wanted a box that opens in a super cool way? We thought it would be fun to create a box that can be unlocked using the correct fingerprint! If we had more time, we would make the box more secure. In the mean time, we have learned a lot and had a lot of […]
