ProtoThrottle Auction for Cancer – It’s Done!
To every one who bid or helped us spread the word, we would like to say a big thanks. The two charity throttles brought in over $2300 for the Princess Margaret Cancer Foundation! We can’t say thanks enough!
ProtoThrottle Auction for Cancer
We will be auctioning off two ProtoThrottles and receivers with full proceeds donated to the Princess Margaret Cancer Centre in Toronto, Canada, in honor of Lionel Strang, host of A Modeler’s Life podcast. Lionel received treatment for Stage 4 melanoma and he raises funds each year to help other cancer patients cope with the emotional burden that cancer brings.

Introducing the ProtoThrottle Pocket
Announcing the latest holder for your ProtoThrottle… the ProtoThrottle Pocket!
Store and protect your ProtoThrottle with the ProtoThrottle Pocket. Made from strong and durable black PETG plastic, this holder will cradle your throttle securely and out of the way when not in use, while still providing access to the controls if needed. Three mounting holes in the back make for easy attachment to a wall or the layout fascia. Click here to purchase.
Tsunami2 True Idle
The Tsunami2 True Idle feature can improve the operating realism of your locomotives when used with the ProtoThrottle. Take a look at this video below from SoundTraxx for more information.
With all of the hype around the new Proto Throttle we have had a lot of questions about our True Idle feature. In this video, our product expert explains the feature, shows examples of how it works, and explains how real locomotives operate in these scenarios.To accurately simulate how a real locomotive runs, original Tsunami2 decoders did not change the prime mover notch when going from speed step 0 to speed step 1. We found that it is a common customer perception that the prime mover should notch up when this happens. So in Tsunami2 software version 1.2 we added this in for you!CVs used in this video:CV 112: Enable the E-Stop Idle, Alarm Bell, HEP Generator and True-Idle Modes.

Dead Rail Interface for the ProtoThrottle
We’ve been asked a few times if there would ever be a dead rail interface for the ProtoThrottle. While this is not something we would likely embark on ourselves (Nathan and I are both N-scale modelers), the open source nature of the design has allowed others to do so. Over the last few months, Martin Sant has been busy building a dead rail interface for the ProtoThrottle to run his G-scale trains. Check out the progress on Martin’s blog.
Decoding the ProtoThrottle Notch Settings
One of the key distinguishing characteristics of the ProtoThrottle Realistic Control Stand Throttle is its throttle handle with eight notches plus idle. With those characteristics detents, you can operate your locomotives like the prototype and have the prime mover sounds respond accordingly. Setting this up on the ProtoThrottle is simple and takes just a few minutes, with the help of the ProtoThrottle, to find where your particular DCC decoder transitions between notches. Those transitions can then be used to pick the optimal speed steps to assign to each notch.
