    Can the Estes E-class launch controller run 12V?

    I got my first RMS from Aerotech, and am curious if I could just hook up a 12V car battery to the Estes E-series launch controller (This One) and use that, or is the gauge of the wire too small such that the resistance would be too high? I'm not very knowledgeable in electronics, and I don't...

    3d Printed DIY Launch Controller

    My DIY launch controller is done! It is a 3d printed multi use and programmable launch controller. Last time I posted it looked like this pad wireless controller by Yukon@K-9 Rocket Tech posted Jun 21, 2019 at 5:13 PM and it has some changes. The system is made out of a gutted remote relay...

I have included a safety key and indicator lights. My question is the continuity and not setting off the ignitors. Diagram...

    Arduino Continuity Circuit and Low Power Launcher

    I just happened to be working on project to build with my 4H group, when I saw this "Ultimate Arduino Challenge". Since I have the basics roughed out, I thought it was worth an entry. A few parts to procure, and we can build it. I am having the kids do the Arduino sketch, and will add it when...

    20 volt launcher

    Has anyone built a 20 volt launch controller? My idea was to use a Dewalt 20V Battery as the power source There are some adapters on ebay for about $20 that adapt a 20V battery into older style tools, I was thinking of getting one of those to use as the battery holder. I was thinking of epoxying...

    Launch Controller Key Switch w/Non-Removable Key in On Position

    Now that I have found some clear and understandable plans for a single-pad wired relay launch controller (kudos to jsdemar for those plans!), I am going to try to build a launch control system. One stumbling block I have encountered is finding a 12V key switch that cannot be removed when the...
