ESP8266 – Avoid infinite reboot loops w/ NodeMCU
Developing a NodeMCU based firmware for the ESP8266 can be quite annoying. If you cause a bug, the ESP will answer with a hardreset.
Esp 8266 – Alternative Adaptor
For getting started faster with my just arrived Esp-07 module, I’ve used a different adaptor concept to get to a 2,54mm pitch.
jQuery Spellchecker & LanguageTool
Spell checking in web application has always been a big thing. Especially if you didn’t wanted to use available webservices like Google Spell Check due to security concerns.
Esp8266 – Measuring temperature
I’ve started to build a prototype for testing purposes with a temperature sensor.
Esp8266 – 2,54mm Adapter soldering
I’ve ordered the Esp8266 in the form factor or model „03“ which has no standard 2,54mm pin headers. If you want to use it with a breadboard, you’ll need to solder an adapter.
Non-obstrusive Hit Counter
Sometimes you want to measure hits in a non-obstrusive way. In my case I wanted to track how often handbooks which are delivered as hardcopy HTML files at work are actually viewed.
A „Who Am I“-function
You’ll know the game. Someone gets a post-it on his forehead with a name and must find this person by asking e.g. „Am I an engineer?“. The answer is always YES or NO. To handle several Spark Cores with different functionality, I’ve implemented this idea as webservice for all my Cores.
Fritzing „Lochraster“
After all electronics for the Death Star where assembled test-wise, I wanted to create a „Lochraster“-layout. Unfortunately that’s not that easy with Fritzing.
Google Script as Webservice II
After having the webservice to determine the travel time for given locations, it’s time to make usage out of it: As part of an emergency organization I’m curious about how much time we can safe by making use of lights and siren.
Esp8266 – THE IoT MCU
Some time ago I discovered some early information about the Esp8266, a very small and especially cheap WIFI module with serial interface.
