3 line to 32 line output expander - SMT version
Yap Mar 05,2025
This project is described at Hackaday.The minimum lines required to use this board are: GND, SER (data), SRCLK (shift), RCLK (strobe). Vcc depends on the power arrangement. You should jumper the ~OESEL (output enable select) to ground if you don't wish to disable the display by signal, or vary the output with PWM, from a controller. The ~SRCLR input is only needed for resetting the output by the controller.This board is designed with optional aspects you can choose to include or not:As mentioned...

Reflow Hot Plate - Controller Board with Arduino Pro Mini
M Mar 05,2025
Remix of the original Reflow hot plate controller board by Curious Scientist based on Arduino Pro Mini in a smaller form factor (80x80mm).I also added an extra connection for a thermistor on pin A0.Please note that the BOM doesn't include the Arduino PRO Mini and MAX6675 thermocouple module.You will have to source those by yourself.If you like, you can use this project for MAX6675 thermocouple module and source only the probe itself.THE SOFTWARE SKETCH IS THE CREATION OF >CURIOUS SCIENTIST<...

PICO TEMPERATURE GUN Version 1
Arnov sharma Mar 05,2025
Greetings everyone and welcome back. Here's something useful.The PICO TEMPERATURE GUN Project is a do-it-yourself temperature gun project that uses the PICO 2 and the GY-906 Infrared Temperature Sensor to take temperature readings and display them on an SSD1306 124x32 OLED screen.The goal was to create an open-source, functional temperature gun from scratch using a PICO 2 and GY-906 (MLX90614), a non-contact infrared temperature sensor with a high precision of ±0.5°C.It provides two output modes...

AC Power Monitoring Using BL0937 IC
Manoj kumar Mar 03,2025
AC power monitoring is an amazing feature nowadays in IoT related applications, such as smart fans, switches and boards. Some good company boards implement this tech in their products and continuously monitor the supplied output power. Monitoring power at local device level has its own advantages, like now we have data, if current increases and something goes wrong it can turn off the whole system and can save equipment from burning. Moreover power monitoring in IoT uses ASIC based designs, I go...

How to Build a Motorized 3D Scanning Turntable for Your Phone
KILIC Mar 01,2025
In this project, I’ll show you how to make a simple motorized turntable for 3D scanning. It has three main parts: a fixed top plate for placing the object, a rotating middle plate powered by a stepper motor, and a base that holds all the components. The top and base plates are connected and stay in place, while the middle plate rotates independently.To ensure smooth rotation, I’ve added bearings that help the middle plate move more easily. For scanning, I used an iOS app, but you can choose any ...

FloppyBoard: a compact and versatile board
Floppy Lab Feb 27,2025
IntroductionHello everyone! Today I present FloppyBoard, a small development board similar to Arduino but designed to be more affordable and feature-rich. Its dimensions are comparable to a standard Arduino. This is the first version, which was also used in my Pet Feeder project. I later created three more versions with improvements.This article is necessary for the realization of the Pet Feeder, a highly appreciated project that has gained interest from those who want to replicate it. For more ...

Arduino Winkeyer Emulator Based on K3NG code
Gordon L Gibby Feb 25,2025
This project allows you to build a working WINKEYER. See the enclosed MANUAL which includes both operating and building instructions. Be certain to set the computer port to 1200Baud if controlling it from a logger like N3FJP etc. See: https://www.nf4rc.club/how-to-docs/alachua-county-arduino-winkeyer/https://www.nf4rc.club/how-to-docs/arduino-k3ng-winkeyer-emulator-locally-developed-morse-code-keyer-manual/https://www.nf4rc.club/how-to-docs/arduino-winkeyer-packaging-instructions/
