Pocket Temp Meter
Arnov sharma Mar 12,2024
Greetings and welcome back.So here's something portable and useful: the Pocket TEMP Meter project.As the name suggests, this is a compact, useful temperature and humidity meter made of an ESP32C3-based development board, an SSD1306 OLED display, an AHT10 sensor, a LiPo cell, and 3D printed parts.Here, TEMP values are taken using the AHT10 temperature and humidity sensor, which displays the data on the OLED screen. We were able to reduce the device's size to a tiny 25x25x48mm formfactor, whi...

LocoConnect I2C Loconet Interface card - Trough hole
Kluit Mar 08,2024
LocoConnect I2C Loconet Interface card - Trough hole versionThe LConnect is a low cost efficient Loconet feedback and accessories decoder for model railroad. It is created to allow extensive but affordable interaction between the loconet bus and model railroad equipment. It has far more features than most commercial of the shelve devices. However, due to the limits of the relatively cheap ATmega328p cpu, the possibilities are not endless. The controller has the following features:Native S88/S88n...

Universal Arduino Staccato controller for SSTC and VTCC Tesla Coils
Pavleski Mar 08,2024
 The VTTC Staccato Controller was developed in the attempt to create longer sparks from VTTCs while at the same time reducing the input power. The Staccato Controller achieves this by operating the VTTC for a full AC half cycle, then disabling the VTTC for a selectable number of AC half cycles. Basically the controller consists of an oscillator with adjustable parameters and a triac or thyristor at the output of the oscillator, which is connected between the cathode of the vacuum tube and g...

High-performance 3-axis stepper motor control panel
Curious Scientist Mar 05,2024
In this project, I show you my new development which is a high-performance 3-axis stepper motor control board. It is high-performance because it uses the super-fast Teensy 4.0 microcontroller and it also uses a modern TMC429 stepper motor ramp generator controller together with three TMC2209 stepper motor drivers. The board can be controlled via buttons and a joystick, and I also programmed it to be fully controllable by sending commands and parameters via the serial terminal.The board is origin...

Pico Powered DC Fan Driver
Arnov sharma Mar 04,2024
Hello everyone and welcome back.So here's something cool: a 5V to 12V DC motor driver based around a Raspberry Pi Pico Board and a couple of electronic components.The Raspberry Pi Pico is the heart of this project.In order to drive the DC motor load, we have integrated the AO4406 N-channel Mosfet IC, a high-power Mosfet used in SMPS for fast switching purposes. Its Vds is 30V and it can withstand a maximum of 13A of current.In a future project, we will use this arrangement in a PC project t...
