CD47 (Rodan) Nixie Tube Clock
Build a CD47 Nixie Clock. Power: approximately 100 Watts. Some may question if this is over-engineered, but it will be justified by the project's outcome. The Nixie tubes will be turned off when not in use to prolong their lifespan....
Advanced LED Temperature Indicator
This verified project provides an idea, circuit, and operation of the LED display temperature indicator. It features a digital temperature indicator utilizing a voltage-to-frequency (V/F) converter, along with various electronic projects.
The LED display temperature indicator is designed to provide a...
5x7 LED display schematic
Your 5x7 display is my favourite toy; the tunes and graphics in the elevator display always impress my mates! Since building the display I developed my own 400 dot matrix using a pic and the SN74154 4bit binary to 1...
8x8 dotmatrix scrolling led display
This project involves a scrolling LED display composed of 64 LEDs arranged in a matrix configuration. The anodes of the LEDs are driven by a driver IC, UDN2981, while the cathodes are controlled using the ULN2803. An Atmega8515 microcontroller is...
LED Volt Meter Circuit LM324
This circuit is a practical device that, when installed in a vehicle, displays the voltage of the car battery using an LED dot display. The meter circuit utilizes four comparators formed from a quad op-amp, specifically the LM324. The inverting...
Audio Beat Detect ?« Electronic Product Design
This circuit employs a digital potentiometer to enable the microcontroller to automatically adjust the circuit's gain according to the ambient audio volume. However, a standard potentiometer can be used if automatic adjustment is unnecessary. The low-pass filter design is based...
Propeller-powered IN-12 Nixie Clock
After constructing numerous Nixie Tube Clocks based on online designs, a personal design was developed. This clock utilizes IN-12 Nixie Tubes and an 8-core Propeller Microcontroller. Although the Propeller may be more powerful than necessary for this task, it is...
Common-cathode-led-display
A Teledyne TSC7135 digital voltmeter (DVM) chip is utilized to control a multiplexed 5-digit display. To facilitate common cathode drive, a CD4513BE CMOS integrated circuit (IC) functions as a segment driver, with selection controlled by pins 17-20 of the DVM...
Nixie Clock Project
Before Light-Emitting Diodes (LEDs) and Liquid Crystal Displays (LCDs), the electronics industry utilized cold-cathode tubes for displaying numbers, symbols, and characters. Although referred to as "tubes," they differ from "radio tubes" in that they lack a heater wire to heat...
