When forgetting to take medication on time can lead to a bad day or night, having a helper to keep you on track can greatly improve your life. [M. Bindhammer] faces this scenario every day, so he built his own robotic pill dispenser. The core of the project is a 3D printed dispensing drum with individual […]

Grizzled veterans of the computing industry will relate stories of submitting projects on stacks of punched cards, something those of us who stored their 8-bit works on audio cassettes could only imagine. But for those who fancy experimenting with the format it’s still possible to make a basic card reader using LEDs and light sensors, as

Robot humanoids are cool, but also a bit hard to make work as they only have two legs to stand on. Four-legged robots can be a bit more approachable. The Dingo Quadruped aims to be just such an open-source platform for teaching and experimentation purposes. The robot is based on the Stanford Pupper, a robot platform we’ve

Having a computer that locks its screen after a few minutes of inactivity is always a good idea from a security standpoint, especially in offices where there is a lot of foot traffic. Even the five- or ten-minute activity timers that are set on most workstations aren’t really perfect solutions. While ideally in these situations

In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting for an altogether simpler desktop fire control solution. This fun build uses a common off-the-shelf USB “missile launcher” that fires foam darts. To supply targeting data

HW9 – Arduino The Task: In our Arduino project challenge, we were free to create anything of our liking, with the only requirement being that the circuit must either read a sensor or control an active component. During a class session, a practice example was demonstrated, involving a humidity sensor, LED, potentiometer, and LCD screen.

CHOOSING A DIRECTION For this assignment, I embarked on my inaugural solo experience with Arduino. After facing some challenges during the in-class tutorial, I felt apprehensive about dealing with the breadboard once more. Consequently, I made an early decision to work on a simpler circuit. While exploring the components of the Arduino kit, the IR
