Low Cost Constant Current/Constant Voltage power supply
Lots has happened in a year, but in the mean time let me tell you about this great low cost ($24) variable power supply with LCD. The DP30V3A
In Development: Throttle with LCD
In development, an arduino based JMRI throttle with LCD Screen, physical speed throttle (Forward/Reverse on the same knob) and up/down/left/right arrows for changing engine, and possibly other settings.
Arduino DCC Monitor
Build a simple DCC monitor with an arduino to help in your decoder development or track troubleshooting. Sketch code and details included.
MRRwA NmraDCC Library
Details on an excellent Arduino library for making your own DCC decoder.
Converting an old MRC Santa Fe to DCC
Some information and pictures on a DCC conversion of a MRC Santa Fe circa 1970-1980.
ESP8266 Wifi Module
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
In this post I explain what a capacitor discharge unit is used for and how to build one using stripboard.
Welcome
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.
