The Grow Cube / Grow Box is an indoor hydroponic setup which can be used to plant and grow seedlings, micro-greens, lettuce, and other plants up to a height of about 75 cm (around 3 ft).Ideally, the system will monitor temperature and relative humidity...
A while ago I needed a quick and dirty way to see what's going on in a clocked down design of mine and found myself with no appropriate tools around (and I was like "oh, shift / carp, digging into something as simple as this with an MSO / logic...
The story so far... Update: Row scanning working.Known/working: Building and loading via JTAG new firmware into the main FPGA. This firmware is starting from scratch, we don't understand much yet about the default Barco firmware, although we've dumped...
Hardware ESP-32: The ESP32 makes it easy to use the Arduino IDE and the Arduino Wire Language for IoT applications. This ESP32 IoT Module combines Wi-Fi, Bluetooth, and Bluetooth BLE for a variety of diverse applications. This module comes fully-equipped...
In the Maker community there are projects to make Virtual Reality headsets to use with the PC, but these are for wired use, so there is room for a wireless solution that does not involve using a cell phone. Currently the best: https://hackaday.io/project/187343-easy-pancake-lensesAnd...
For lack of a better place, the Instructions project section gives a detailed description of the system. Last update September 25, 2018. If you would like more information on the custom Raspberry PI board that controls the system, there is another...
The main differences between the E6400 and the T400 are the SuperIO, the EC, and the use of DDR2 RAM instead of DDR3. The SuperIO is supported by coreboot, so it should just be a matter of including it in one of the files, but I may have to write new...
Blinking LEDs, what can be easier, right? For a recent project I needed to multiplex 2 sets of 6 LED each. The circuit schematic has the LEDs driven by 6 pins on an Arduino plus two pins to activate one bank or the other. LEDs are these ones from LCSC....
The JP-QR701 specifications indicate that it has GB2312 support. I think this also applies to similar products that all seem to come from the same OEM or at least from the same design. Most documentation - especially that found on English-language distributors...

This project consists of two components: A Windows utility to retrieve, process and send system statistics in a simple string of characters to a serial port. An STM32 connected to a TFT screen to receive the serial data and display a smooth scrolling...
I came up with a nice (from my own standpoint) circuit arrange that tester each and every pin of my Arduino-compatible board:- Pins 0 and 1 = Serial communication with a PC, through the "Serial.print()" command- Pins 2 and 3= an LED connected between...
