ESP8266 Wifi Module

  • Posted 5 January 2015

The ESP8266 is a great cost effective module to add to any Arduino project for communication.
It is a $3 wifi-to-serial module with minimal parts and a simple command set.
Want to make a remote temperature sensor ? What about remotely controlling a light bulb ?
Possibly checking the status of your train while away ?

I ordered a few of these a while ago and finally got around to setting up a test circuit. Read more to see the circuit and details.

Capacitor Discharge Unit

Welcome to the new blog. I hope to work on starting up an old n-scale model railroad set and bringing it to the 21st century with the use of DCC and other computer technologies.
I will be posting DIY information so that you can build all the parts you might also need.
Circuits, schematics, information, and tips.

Keep checking back often for new posts.

Look for the first post on building a Capacitor Discharge Unit on a breadboard pcb (aka protoboard) to run turnouts/points that use solenoids.
