MicroUSB-powered ESP8266 OLED Board (omiker0’s Blog)I created this design as a challenge to make a design under 1″ x 1″ in size.ESP8266 Oled Board Rev3by miker
Briefly: 80-wire IDE cables are *great* for high-speed stuff... But the pinout is a bit more difficult than a straight-through 40-wire IDE cable, because the 80-wire cables have shielding (yay!) which is connected to specific pins designated as ground,...
When it comes to homebrew computer designs, nothing beats the classic microprocessors from 1970s and 1980s. SDC is an idea of a computer bringing together old and new technologies. The SDC consists of some real, classic CPU and a modern microcontrollers...
This project shows how to use the STONE display, STM32 microcontroller, ultrasonic sensors, and a servo. The purpose of the project is to be able to display the distance measured by ultrasound in real-time through the STONE display....
My name is Dmitriy Dudarev. I develop electronics, and I love to create different portable devices. I also love music. A long time ago, in April 2020 or so, when the whole world was shaken by the terrible quarantine, I decided to learn to play...

The novel coronavirus has caused nearly more than 80 thousand confirmed cases nationwide, and the respirators and respirators are in short supply in recent months. Not only that, but the situation abroad is also not optimistic. The cumulative number...
I needed a 7.2V battery pack for an ongoing project. Too lazy to go and buy pre-made packs, I made my own. The cells are bog-standard Lithium-ion 18650s recovered from laptop battery packs. I cycled them twice with an Accucel charger to check the capacity....
ESP32 The ESP32 development boards are not without their problems. Why keep using them anyway? The ESP32 IC only costs €2.31/pce on Digikey. Design a decent breakout board and done! Well, if you don't want to design your own...
Product Overview The STM32F105xx and STM32F107xx connectivity line family incorporates the highperformance ARM® Cortex®-M3 32-bit RISC core operating at a 72 MHz frequency, highspeed embedded memories (Flash memory up to 256 Kbytes and SRAM...
In the age that electrification is undergoing, changes that occur in the lithium battery market will be exponentially increased. Since the introduction of the 4680 battery, the plates associated with the battery have become uneasy. According to...
The LRS-150-24 power supply can operate from a 100–120 volt or 200–240 volt AC network. The manufacturer states it provides an output current of up to 6.5 amperes at 24 volts. The supply measures 5¾ × 3¾ × 1¼ inches (145 ×...
In this article I'm going to go over a 2in diameter omnidirectional sphere I designed. Prior Designs and Builds The design is based of what is shown in this video. This video shows the same design, but scaled up and 3D printed. Requirements...
