DIY Sensitive STM32 Pulse Indiction Metal Detector (Arduino IDE)
Pavleski May 05,2023
 This time I will show you how to make a sensitive Pulse Induction metal detector which is based on ARM STM32 microcontroller, which has significantly better features than Arduino and is also cheaper. It can detect metal coih at distance of 30cm, and big metal object at distance of more than 80 cm. The positive thing is that you can install an Arduino bootloader on it, after that you can use it as a regular Arduino. This is my first project with this microcontroller and the experiences...

OverEngineered Phone Stand
Arnov sharma May 04,2023
Greetings everyone, So here's something super useful and awesome: "THE OVERENGINEERED PHONE STAND" made completely from scratch by using Custom PCBs and 3D Printed part.Fusion 360 was used to create this phone stand. The main body is entirely 3D printed, with PCBs covering both sides. The PCB contains an IP5303 setup that converts the onboard lithium cell's 3.7V to 5V, which is then used to power 5 RED LEDs that illuminate the entire phone stand.Why were red LEDs used? for no part...

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&...
