Seamless TV DNS switching with dnsmasq and Home Assistant

Some Black Friday ago, I happened to buy a lifetime subscription to Getflix. It’s a service that allows you to bypass Netflix regional restrictions by using their DNS servers. The advantage is that you don’t get stuck with lower speeds as you probably would with a VPN. The service has been working pretty well apart from a few outages some time ago (looks like Netflix is actively working against…

New ATX Breakout Board PCBs (with some improvements!)

Hello everyone, I’ve got some good news today! I released a newer version of my ATX Breakout Board. After receiving a lot of requests, I also printed some PCBs (10x blue, 10x red) and will print more after thorough testing of the current revision.

NodeMCU library for the TI HDC1000 sensor!

It’s been a while since I received my NodeMCU development board but I have only been able to get my hands on it lately. I soon downloaded the ESP uploader and after reading some Lua docs (and finding out some weird things such as that the “not equal” operator is actually “~=” ) I started writing my own code for the board. Writing and uploading software to the board is easy and fast. The only…

HDC1000 temperature and humidity sensor breakout, with Arduino library!

Some time ago I came across a new chip from TI, the HDC1000. It’s a temperature and humidity sensor with I2C interface and requires little to no additional components. It comes in an 8BGA package: we can all agree it’s pretty small. Some of the peculiar characteristics of this chip are that it has a DRDYn pin which goes low any time there is a new reading from the chip (so you can precisely time…

LSF0204 breakout board: a bidirectional, multi-voltage level converter!

Hello everyone! I needed a small, fast and reliable multi-voltage level translator (mainly for connecting ESP8266 boards to the Arduino, got tired of resistor networks pretty quickly) so I built a breakout board for TI’s LSF0204(D). Datasheet and info here. The LSF0204 is a nice little chip. It can translate up to 4 signals to and from the following values: 1.0 V ↔ 1.8/2.5/3.3/5 V. 1.2 V ↔…
