The Magic Touch: A 555 Touch Switch

https://invidious.privacyredirect.com/watch?v=IfS6JmnjBhQ

There seems to be nothing a 555 can’t do. We’ve seen it before, but [electronzapdotcom] reminds us you can use a 555 and a few parts to make a reasonable touch switch in this video, embedded below.

The circuit uses some very large resistors so that noise from your body can overcome the logic level on the trigger and threshold inputs. You can easily adapt this idea if you need a simple touch switch. Though we imagine this circuit wouldn’t work well if you were in a quiet environment. We suspect 50 or 60 Hz hum is coupling through your finger and...

LILYGO T-Deck Pro – An ESP32-S3 LoRa messenger with e-paper touch display, keyboard, and 4G LTE or audio codec option

LILYGO T-Deck Pro is a LoRa messenger based on an ESP32-S3 WiFi 4 and Bluetooth 5.x SoC, and offered with a 3.1-inch e-paper display with touchscreen, a Blackberry-like QWERTY keyboard, a GPS module, speaker, microphone, and a 3.5mm audio, as well as IMU and light sensors. It builds upon the T-Deck Plus design, but replacing the 2.8-inch IPS display with a 3.1-inch e-paper display allows for a slimmer design and should offer longer battery life despite the smaller 1,400 mAh battery used in the new model. Two versions of the T-Deck Pro are available: one with a Simcom 4G LTE...

Batteryless 7.5-inch NFC-powered e-paper display V2 gets new NFC chip and “fast flashing method”

Back in 2020, we wrote about Waveshare’s Batteryless NFC e-paper display, which can work without a battery and draws power and data from an NFC-enabled smartphone or the company’s ST25R3911B NFC board. Waveshare has now released a V2 version of this display with a new and improved NFC chip, a “fast flashing method”, and enhanced contrast. The new batteryless, 7.5-inch NFC-powered e-paper display features an 800×480 resolution and updates via an NFC-enabled smartphone or reader. It offers a 170° viewing angle and comes in a durable ABS plastic shell. The ST25R3911B NFC board allows updates via USB, SD card, or...

P42 Pico2 M.2 – A Raspberry Pi RP2350 board in M.2 form factor

The P42 Pico2 M.2 may look like an M.2 module, but it’s actually a Raspberry Pi RP2350 development board in M.2 2230 form factor whose edge connector exposes USB, UART, I2C, and control I/Os. The board ships with a 2MB SPI flash and complies with voltage levels defined by the M.2 specification, with some of the interfaces running on 1.8 V. The SWD interface, +3.3 V, GND, and 16 IOs are accessible on castellated pins, and there’s also a QWIIC connector for I2C modules, but it’s not populated by default. The board also comes with a microSD card slot on...

NV8600-Nano AI Developer Kit features NVIDIA Jetson Orin Nano 8GB, quad GbE, Raspberry Pi Camera Module 2

AAEON NV8600-Nano AI Developer Kit is based on a 67 TOPS NVIDIA Jetson Orin Nano 8GB and ships with a carrier board with quad GbE, a Raspberry Pi Camera Module 2, a fan kit (heatsink with fan), and a 60W power adapter. The carrier board is also equipped with a 256GB M.2 2280 M-key NVMe SSD, a SATA connector, HDMI 1.4 video output, two MIPI CSI connectors compatible with Raspberry Pi Camera Modules, six USB 3.2 Gen 2 Type A ports, a few serial interfaces, a 40-pin GPIO header compliant with the Jetson Orin Nano (Super) developer kit, and two...

10-cent WCH CH570/CH572 RISC-V MCU features 2.4GHz wireless, Bluetooth LE 5.0, USB 2.0

Patrick Yang, CTO at WCH, has recently unveiled the CH570 RISC-V SoC with 2.4GHz wireless and USB 2.0 (host & device) as an upgrade to the popular CH32V003 general-purpose RISC-V MCU with more features at the same low price (10 cents). CH570 also comes with 12KB SRAM and 256KB flash (vs 2KB SRAM and 16KB flash for the CH32V003), offers up to twelve GPIO,  six PWM, I2C, UART, SPI, and a 20-channel key detection module. There’s also the CH572 with the same features, except it also supports Bluetooth LE 5.0. As a side note, I wrote about the CH572 RISC-V...

Совершенно секретно. На самом деле Linux — это не просто операционная система, а …

Что, если Linux — это не просто операционная система, а гениальный психологический эксперимент, созданный тайной организацией «Кодекс Нова»? Их цель — заставить людей массово перейти на Windows, сделав Linux настолько сложным и запутанным, что пользователи в отчаянии выберут «удобство» Microsoft. Случайно ли ядро Linux названо «ядром»? Это метафора: оно скрывает истину, как ядро в плоде. Торвальдс, якобы создатель Linux, на самом деле — агент Кодекса Нова, внедренный для создания иллюзии свободы выбора. Почему документация Linux такая запутанная? Чтобы оттолкнуть новичков. Почему так много дистрибутивов? Чтобы вызвать паралич выбора. Истинная цель — заставить людей поверить, что Windows — единственный «простой» выход....
