Build a simple 3D printed CNC plotter machine
KILIC Nov 03,2024
Hi friends, do you remember this Mini CNC Plotter machine that uses hobby stepper motors and a few 3D mechanical components, now meet its big brother. This new machine includes two linear rails and two Nema 17 stepper motors for the X and Y axes. It also uses a mini servo motor for the Z axis to lift the pen. There is also a wheel with mini bearings to support the linear rail on the Y-axis. In the circuit part, I used an Atmega-based printed circuit board that I designed, which enables...

Stanley A Meyer Switch Arduino PWM Esp32
Donatelli Nov 02,2024
Much like the 2N3904 Simplified approach, we can do the exact same with a small N-fet. This circuit expects 4 input signals, 2 from the ESP32, or from any other signal generator you have that can be constrained to 0-5V. Since the FET needs a B+ and load at its Drain, the TIP42C Darlington is chosen for its 100V rating and hfe=1000, similar to the TIP120 (60V rated). The Darlington transistor allows a linear mode operation during T1, up to 5mA.Each leg is a separate AND gate, and could be broken ...

160 Channel Configurable DAC Controller
Joseph Nov 02,2024
The DAC controller board features 160 individually controllable 16-bit DAC output. It can output voltage ranging from 0-20V on each channel.The PCB contains 10 DAC81416RHAT- 16-channel 16-bit high-voltage output DAC with integrated internal reference from Texas Instruments. All ten DACs are daisy-chained and controlled using a single central microcontroller. All outputs are accessible from the 20 IDC connectors placed at the edges of the PCB. Each IDC connector will have 8 DAC channel outputs an...

Offline Voice-Controlled Home Automation System
Maa Nov 01,2024
In this project, we’ll explore an offline voice-controlled home automation system that allows you to control appliances without relying on the internet. This system is ideal for places with unreliable internet connections or where privacy is a priority. It uses a custom PCB, an offline voice recognition module, a microcontroller, and relay modules. Let's dive into how it works, how to build it, and the programming behind it.How the System Works;)The core of this project lies in the offline voice...

Arduino HPDL1414 Retro Clock with Set and Alarm Functions
Pavleski Oct 31,2024
 The HPDL-1414 is a 16-segment LED display with four printable fields that is over twenty years old. It has a red GaAsP screen to which we can add the epithet "smart", because it is capable of printing alphanumeric characters on its fields. The screen is controlled by a CMOS integrated circuit embedded in a plastic housing.This circuit contains RAM, ASCI II decoder, multiplexer and LED drivers. Thanks to these features, no additional components are needed to connect this display to the...

LEDs Stars
🙂 Oct 31,2024
Hello everyone!  I'm signing up for this competition with a small project designed to attract your attention (if it really can do that  to adults, rather to children), like the stars in the sky. This project that I named "My Galaxy" is the result of some attempts that date back some time, but I will talk about it during the presentation.In short, the list of components is something like this:- 1 card with ATMega8AU-TH;- 4 rings with WS2812B LEDs;- 1 IR detector module;- 1 pus...
