CASDuino (and similar) Compatible Player for Computer Cassettes
Reboot May 02,2023
This hardware runs CASDuino and similar compatible Arduino sketches in an Arduino Nano.The OLED display shows a list of .CAS cassette audio data image files stored on a micro SD card in the on-board card socket.Buttons can be used to navigate the file list and then used to begin playback or stop playback of the desired cassette file.Audio is sent out with a 3.5mm jack, which can be connected to the audio input of retro computers that had a cassette interface connector.There is also a 2.5mm jack ...

Simple ESP8266 NTP Clock on VFD Display VFD256x50 GP1287
Pavleski Apr 28,2023
 A VFD (Vacuum Fluorescent Display) is an electronic display device that is commonly used for displaying numeric or alphanumeric characters. It is similar to an LCD (Liquid Crystal Display) but uses a different technology to display information. VFD displays are known for their high brightness, high contrast, and wide viewing angle, making them suitable for use in a variety of applications, including digital clocks. Exactly such a clock is described in this video. I recently acquired a...

Teapotlabs Feather RAK3172: Low-cost LoRaWAN Development Board
Laboratories Apr 26,2023
Teapot Feather RAK3172 breaks out RAKwireless RAK3172 to an Adafruit Feather-compatible format.At the heart of the device is the RAK3172, a STM32WLE5CC based module with ARM Cortex M4 processor, 48 MHz and 3.3V logic. The chip has a 256K of flash and 64K of RAM. With low-power application in mind, the board is capable to be in sleep mode for as low as 12uA, it also has a built-in voltage divider to sense battery voltage and battery charger.Teapot Feather RAK3172 is heavily inspired by&...

Arduino Tachometer (RPM meter) with IR sensor module
Pavleski Apr 21,2023
 A tachometer is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on Analogue dial, or on digital display. In this project, tachometer is made using an IR Sensor module as unit for measuring the number of rotations. Simply we have interfaced the IR sensor module with Arduino nano and the SH1106 Oled display. The sensor module consists of IR Transmitter & Receiver in a single p...

AY-3-8910 Sound Generator (Arduino Nano Controlled)
Reboot Apr 20,2023
The AY-3-8910 sound generator has an 8 bit address/data bus, allowing access to 16 internal registers.Using Arduino Nano and a library, the registers can be controlled to generate 3 channels of audio tones or noises.Their amplitude (volume) can be set, either by setting a fixed volume or by turning on an envelope feature to make the volume fade in/out etc.YM format chiptune files can also be played, either from program memory or an SD card.

LED Fader Using 555 Timer IC
Adhikari Apr 18,2023
LED Fader Using 555 Timer ICWanted to generate a LED fading effect (fade-in and fade-out) for my upcoming video tutorial using the 555 timer IC.I already have a video where I used LM358 Dual Operational Amplifier IC and another one with Arduino to generate the LED fading effect.YouTube, is full of video showing how to generate the fading effect using 555 timer IC. However, none of them produce a true fading effect. Some just fades-in but never fades-out. And there is literally no explanatio...
