The BasicDCC Project
This is a basic, Do it Yourself DCC Controller designed
around my BasicMega project. It is built around the
ATMega328 microcontroller and has been designed to
fit either the Hammond 1592ETCD (Hand Held) or
1599KTS (Sloped) style enclosures.
This design creates four analog DCC throttles
and the basic headlight controls. Arcade style
push-buttons are used to control the headlight.
A 16x2 LCD is used to display Direction, Speed
and Headlight status of each locomotive.
The handheld unit connects directly to it's 3amp
companion booster through a standard RJ11 telco
cord. This allows the unit to be powered from the
booster while supplying the DCC data on only
This is a DCC Booster project of basic design based
on the ATTINY-13 microcontroller. The microcontroller
handles the SIGNAL DETECTION, FAIL SAFE and
DRIVE LOGIC to feed a common stepper motor driver.
Opto-isolated input protection is handled by either
a PC817 or 6N137 optocoupler
It works well with most 12-16vdc power adapters with
a rating of 700ma -3amp. I found that an adapter rated
at 700ma runs 4 Atlas N Scale locos quite comfortably.
I had 9 locos running with a 3amp source and the
L289N was just luke warm after an hour.
