  This DCC Booster was designed to solve two issues that putting a lot of DCC accessory decoders on your layout brings up. 1) They are a drain on your precious loco amps and 2) When a loco causes a short all the accessories lose power.  To solve this problem we have made a DCC booster that can be used for accessories on any brand of DCC system.  It can provide about 5 Amps of power to run the DCC accessories independent of the track power from your command station.  During a short on the layout, when the DCC signal dies, the booster continues to deliver full power.  This is a so-called "dumb" booster in that it does not need a cab bus - it connects directly to the track output of your existing command station. You can also use the booster as a "powered circuit breaker".  It fills all the functions of a circuit breaker but provides its own power.  Each of your power districts puts no load on the command station as it is fully buffered.  I use sever...

Yun Shield is one of the most powerful shields for Arduino Board. Yun Shield is designed to solve the Internet connectivity and storage issue for Arduino Board.    Yun Shield runs Open Source OpenWrt system (Same system as runs in Arduino Yun) and it is fully compatible with Arduino IDE v1.5.4 or later. Yun Shield is the ideally choice for Arduino Projects which require various internet connections and more storage.    Basically, Yun Shield + Leonardo equally to the official Arduino Yun, but Yun Shield is more flexible because it can work with other Arduino board such as Uno, Duemilanove, Mega etc. And Yun Shield uses external wifi antenna which provides stability and possibility for various environments.   Features •Open source Linux (OpenWrt) inside •Low power consumption •Compatible with Arduino IDE 1.5.4 or later, user can program, debug or upload sketch to Arduino board via Arduino IDE. •Managed by Web GUI, SSH via LAN or WiFi •Software upgradable via netwo...

  DCC-EX, a global contributor to DCC open source software for model railroading, is proud to announce the first of our open source hardware products: the EX-MotorShield8874 providing dual 5 amp DCC and DC PWM (pulse width modulation) output for DCC-EX Command Stations. The EX-MotorShield8874 addresses the needs of DCC-EX users wanting to run multiple locos, across multiple power districts without requiring expensive DCC boosters. A DCC-EX Command Station can now outperform commercial DCC command stations which typically have single 3-3.5A or 5A output capabilities, and doing so at a fraction of the cost and with more advanced features. The EX-MotorShield8874 is the first offering in the DCC-EX open source hardware ecosystem specifically designed for model railroaders, and is a direct result of the strong community engagement DCC-EX strives to inspire. DCC-EX hardware lead Paul Antoine says “the open source vision for hardware designs from the DCC-EX community means individual user...
