Blunami vs Poor Man's Throttle

The Blunami train control app by BlueRail Trains let's you control any locomotive equipped with a SoundTraxx Blunami DCC decoder.

FREE DIY Wireless Model Train Control — Built for Hobbyists, **Poor Man’s Throttleturns your smartphone into a wireless throttle for model trains. Designed formodel railroad hobbyists, makers, and DIY builders**, the app allows you to control a locomotive using inexpensive electronics instead of costly commercial control systems. With simple ESP32-based hardware, your phone becomes asmooth, responsive wireless throttle**. --- Smooth Motor Control Many traditional DC transformers struggle with low-speed operation. Locomotives often: • hum at low speeds • start with weak torque • move in jerky steps Poor Man’s Throttle solves this by usingPWM motor control (Pulse Width Modulation)instead of simply lowering voltage. This allows locomotives to: • start smoothly • run at extremely slow speeds • maintain strong torque • eliminate most transformer hum --- Wireless Smartphone Control Control your locomotive directly from your phone. Features include: • Speed control • Forward direction • Reverse direction • Stop • Additional command support Because control is wireless, you canwalk around your layout while operating trains**, just like with professional wireless throttle systems. --- A Major Upgrade for Traditional DC Layouts Poor Man’s Throttle works especially well with classic DC transformers. Instead of using the transformer to regulate speed, the transformer is set tofull powerwhile Poor Man’s Throttle performs the motor control using PWM. This approach provides: • smoother slow-speed operation • higher starting torque • reduced transformer noise • modern wireless control for classic layouts --- Perfect for Dead-Rail Builders The system also works extremely well withdead-rail locomotivespowered by onboard batteries. Builders commonly use: • cordless tool batteries (DeWalt, Milwaukee, Ryobi, etc.) • lithium battery packs • LiPo or lithium-ion cells • NiMH packs • other hobby batteries This flexibility allows hobbyists to useinexpensive, widely available power sources**. --- A DIY System That Costs Around $20 A typical Poor Man’s Throttle hardware build costs about: • ESP32 development board • IBT-2 motor driver • 5V logic power module Total hardware cost is oftenaround $20 per locomotive**. Many builders already have some of these parts available. --- Built for the Model Railroad Community Poor Man’s Throttle was created to makewireless train control accessible to everyone**. Instead of expensive proprietary systems, this project focuses on: • simple hardware • open DIY building • affordable components • sharing knowledge with the hobby community The goal is simple: **Give model railroaders a powerful wireless throttle they can build themselves.** --- Who This App Is For This app is ideal for: • model railroad hobbyists • dead-rail builders • DC layout operators • electronics makers and tinkerers • DIY train control enthusiasts Bothbeginner buildersandadvanced hobbyistscan use the system. --- Learn More Hardware build guides, documentation, and project information are available through the Poor Man’s Throttle project resources. https://github.com/jamocle/PoorMansThrottle-DIY/blob/main/README.md Build your own throttle.
