Feather ULN2003 Stepper Wing
Details from Feather ULN2003 Stepper Wing
This Feather Wing was designed solely with through-hole components, which are easier to put together by hand for small runs. In the future I may make a version with SMD components as well for professional manufacture. I made this to control...

NEJE PCB Exposer
Details from NEJE PCB Exposer
The "NEJE Diy Mini Engraver" (google it or aliexpress it) is sold in basically different forms: Open Gantry style and Framed Enclosre style.To my knowledge there is no official manufacturer for it. The hardware design seems to be derived from this project...

ESP8266 Stepper Driver
Details from ESP8266 Stepper Driver
Forth The first Forth I found that runs on the ESP8266 is PunyForth. I am still exploring it, but it seems to have lots of tools to work with ESP8266 capabilities. A Forth environment is so extensible that the line between what is the system and what...

Nixie IN-3 Matrix
Details from Nixie IN-3 Matrix
The display is driven from two large PCBs. Each board contains a high-voltage power supply and two 32 bit shift registers. The shift registers, Microchip HV5122, have a logic level of 12v so a ULN2003 transistor array is used to level shift the signals...

Home Automation Using Cortana

Antarctic Time Lapse GoPro Panoramic Mount
Details from Antarctic Time Lapse GoPro Panoramic Mount
A Friend of a friend was going on a trip to Antarctica and was looking for a way to take 360 degree photos with his GoPro to create a Time Lapse video. Because I'm always looking for a way to create content for my YouTube channel, I said I'll make the...

DIY Arduino 3D Printed gear Clock
Details from DIY Arduino 3D Printed gear Clock
Today I will show you how to make a 3D Printed Arduino clock. In fact, it is not a precise clock, but a visually interesting device. It consists of a set of gears powered by a small stepper motor. ...

Details from Peters 7-seg all mechanical display prototype 2
This is a prototype !I am already working on prototype 3 so i won't put more time into this one.But by request i uploaded the current prototype to thingiverse all files ar located there :-)And remember its not a polished finished project.. First...

Arduino Ultrasonic Radar
Details from Arduino Ultrasonic Radar
With a small modification of the ultrasonic sensor module, this radar is capable of detecting multiple objects with each ping, which means that it can also detect an object behind an obstacle. Points on the radar display, representing primary...

Darth 3.0, A Stepper Motor Driven Darth Helmet.
Details from Darth 3.0, A Stepper Motor Driven Darth Helmet.
I'm still experimenting with stepper motors on this prototype, and I'm quite pleased with the facet alignment of the Darth Vader styled helmet, quite impressive for 3D printing. To make animating the model easier (for me at least), I wrote a very simplistic...

Chiming Clock
Details from Chiming Clock
Chiming Here are some videos of the sound after mounting the tubes better. Here is a version using 3 gongs (steel bowls from a thrift store) ringing 6 o'clock. This is using the "All Quarters - 3" mode (see below). Here is my test setup, with 2 bells...

BCD-Clock with RPi zero W
Details from BCD-Clock with RPi zero W
Easy to Build Reducing the electronic components to one RPi, the LEDs, and the wires between them allows you to concentrate on the form and design. LEDs Using standard LEDs with a maximum of 3.1 volts. Any color and shape you like. The current to the...

Automatic Water Level Indicator using Arduino
Details from Automatic Water Level Indicator using Arduino
Working of Automatic Water Level Controller We have used the Ultrasonic sensor module which sends the sound waves in the water tank and identifies the reflection of sound waves that is ECHO. First of all, we need to trigger the ultrasonic sensor module...

Interfacing Stepper Motor with Arduino Uno
Details from Interfacing Stepper Motor with Arduino Uno
About ProjectStepper Motor (28-BYJ48) : Not like a normal DC motor, this one has five wires of all superior colors coming out of it. Steppers motors do not rotate, they step and so they also understood as step motors. Which means,...
