This project uses green surface-mount LED’s along with an AVR ATTiny45 microcontroller to simulate the behavior of fireflies in a jar. (note: the firefly behavior in this video has been greatly sped up in order to be easier to represent in a short film. The default behavior has significantly more variance in its brightness and […]

A prototype electric motor that uses a new principle for transforming electricity into rotary force is being developed at C-Motive Technologies, a company co-founded by UW-Madison assistant professor Dan Ludois. Photo: Dan Ludois A tabletop motor using an entirely new driving principle is under development at the headquarters of C-Motive Technologies, a startup business that

When I say simple, I don’t mean use a speed control. But control the motor directly without any external circuitry. Here’s how: How this came about: I recently was working on an instructable about charlieplexing with an arduino. And I was wondering if the same principle would work with motors to some extent. So I came

This week, we’ll finally be using the Arduino to control some motors! First up, we’ll control a standard DC motor running off a 9V battery with the help of an NPN transistor and a PWM (Pulse Width Modulated) signal from the Arduino. Next, it’s onto 180 degree servo motors, which we will power on

This instructable will show you show to build an Arduino shield which can be used to control 3 servos and 1 stepper motor using 4 potentiometers. You will need: access to a laser printer/cnc router/etching chemicals 7 x 3 pin 3.5mm terminal blocks 2 x 2 pin 3.5mm terminal blocks 2 x 8 pin stackable

Stewart platforms are pretty neat, and not seen in the wild all that often, perhaps because there aren’t a vast number of hacker-friendly applications that need quite this many degrees of freedom within such a restricted movement range. Anyway, here’s an interesting implementation from the the curiously named [Circular-Base-Stewart-Platform] YouTube channel (no, we can’t find

Those old enough to have encountered punch cards in their lifetime are probably glad to be rid of their extremely low data density and the propensity of tall stacks to tip over. But obsolete as they may be, they’re a great tool to show the basics of binary data storage: the bits are easily visible

LabRecon allows one to build rich graphical interfaces for “remote” IoT (Internet of Things) or “local” measurement and control applications. A drag-and-drop panel builder and graphical “Wiring” programming environment allows one to easily build an interface and create the operating logic for any project. This operating logic can be further expanded using the “code link” interface

Hephaestus, my own 3D printer I finally did it, I designed and built my own 3D printer. This is in no way “the best 3D printer”. Instead, this was an epic and nightmare project that exercised my ability to engineer and build my own CNC machine. Along the way, I figured out what I did

600V intelligent power modules (IPMs) from Infineon make up the CIPOS Micro IPMs. They are qualified for harsh humid environments, passing 1000 hours of high voltage, high temperature and high humidity reverse bias (HV H3TRB) stress testing. This makes the energy-efficient IPM suitable for power appliance motor drives particularly in circulator hydronic pumps, drain pumps for washing machines, dishwashers,
