I was recently in need of a PWM controller to use with my home automation system for some of my LED strips.
Here’s what I built…
Download: Board design (EAGLE)
ESP8266: WiFi + MQTT
ATtiny85: High frequency (1kHz) PWM modulation
This is a quick guide to cross-compile kernel modules for Android, with particular reference to the J3 2016 LineageOS kernel. The steps outlined work for other devices/kernels as well.
This is a short guide on how to cross-compile iproute2 on Android.
Where the sch_netem kernel module is available, tc – which comes with iproute2 – allows for traffic throttling/packet delay useful to test apps on slower internet connections.
In Home Assistant sensors added to the platform without any further configuration appear in the top bar as rounded icons which can be annoying and not desired at times.
To change such behaviour and have them being displayed as cards it’s sufficient to add those to a group like so:
This is an Arduino routine to check if a button is pressed using the Arduino SDK.
Just brought this dev board from AliExpress: Click here
I’m very excited to learn all about it!
Here’s some docs and examples I found on the internet:
This is my new electronics project, it’s called USB Password Keychain.
It consists of a USB device which is recognized by your PC as a keyboard, through some software I wrote you are able to upload into the EEPROM memory of the chip up to 4 password and with the simple press of a button they are automatically typed in.s
In this tutorial a demo project will be explained, communication is established between PHP and Arduino using a simple intermediate C program which runs as a Linux daemon.
The concept used here is Unix local Sockets, a fast and effective way to perform IPC (or Inter-Process Communication) on Unix based systems.
Basically It’s a weather monitor based on Yahoo! APIs, the Raspberry Pi downloads today weather and the forecast for tomorrow from Yahoo!, this is nicely done through a python script.
