Dashboard4Ewon vs Thrustline Rocket Toolkit

PROBABLY THE COOLEST VISUALIZATION FOR YOUR EWON® Dashboard4Ewon is a local visualization, which will be hosted on your Ewon device. Your machine data will not be transferred to any cloud. But of course, you can open your Dashboard via Talk2M, M2Web or directly via LAN connection. Yes: We save your Dashboard files on our servers so that an update of any dashboard is easy as possible and done in seconds. Means: Once a dashboard visualization is uploaded to an Ewon device, you never have to touch that Ewon again, to update your dashboard. We continuously develop the Dashboard Designer and always provide our users with the latest version. No visualization software needs to be installed. The biggest advantage: no matter what operating system you use, you can use the Dashboard Designer for Ewon on any device with a browser. The Dashboard Designer is the tool to create your Visualization for your Ewon.

Thrustline Rocket Toolkit is a fully offline design and stability companion built for model rocketry hobbyists — from Estes starter kits to high-power NAR/TRA builds. No live data feeds, no sensors, no gimmicks: just real physics you can trust before every launch. Enter your airframe dimensions, fin geometry, and nose cone type to get an instant Barrowman-equation Center of Pressure calculation. Add component masses and positions to compute your Center of Gravity, then see a clear, color-coded stability diagram in calibers so you know at a glance if your rocket is stable, marginal, or unstable. Predict performance with a numeric drag-based altitude and velocity simulator, using your rocket's mass, motor impulse, and frontal area to chart altitude, velocity, and time-to-apogee. Browse a bundled offline motor reference library spanning A through O impulse classes with thrust-curve charts, or add your own custom motor data. Keep your build organized with a parts and inventory tracker for tubes, fins, nose cones, motors, parachutes, and wadding, complete with low-stock reminders. Attach build photos and notes to each rocket, and update weigh-ins to automatically refresh your stability calculation. Before heading to the pad, run a customizable NAR/TRA-style pre-flight safety checklist covering igniter, recovery, and range-safety steps. Then export a clean, shareable one-page PDF flight card summarizing your design specs, stability margin, and predicted altitude for your range safety officer. Thrustline Rocket Toolkit works entirely offline, with no account, no subscription gimmicks, and no network dependency — just a dependable engineering tool for hobbyists who care about doing it right.
