launch controller

Look what came in the mail today!

I have a home-built launch controller that previously used 6 AA batteries, and has worked flawlessly for several years. I recently upgraded it to a LiPo (2200 mAh 3s 50c) rechargeable battery. It seemed to work fine in testing, so I took it out to the field. First launch attempt, igniter burned...

So the other day, my son Jack (who's 2) and I went out to our local park to fly some small stuff. Because he's 2 and has a short attention span, I had everything read to go. Igniters in rockets, chutes packs, the works. We launch our first rocket (a Der Red Max on a C6-5), goes great. The...

Our local NAR chapter is considering stepping up to HPR launches. Looking for recommendations for pads and wireless launch controllers.

Hello fellow rocketeers, I hope you are doing well. I am currently designing a rocket that will fly with a G or H motor but I have a problem. Because I live in Spain and here, rocketry isn't commonly known like in USA and around, it is very hard to find and buy certain elements. Today I'm...

We’re gearing up for our first rocket launch, and I wanted to test our Estes launch controller, so I got out my voltmeter. I figured I’d probably see zero volts across the clips until I had both the key in and the button down, at which point I’d see around 6-7 V and a light. That is not what...

I built a Ground Control Station for model rockets. To keep cost low, I used a toolbox, and parts from separate controllers and integrated into one unit

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...

Made this Open Source rocket launch computer. It's an arduino uno sheild. https://hackaday.io/project/170367-woof-rocket-launch-computer-v4

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...

Hey everyone! I am new to model rockets and I was building my own launch controller, my issue is that when I hit the button to launch the rocket the igniter slowly smokes but never launches the rocket. is a 9V not enough for the low power rocket igniters? If not, what small batteries would...

I am in the process of building my own launch controller. I have came up with a schematic and am looking for more input on what I might need to make it safe and reliable. I have included a safety key and indicator lights. My question is the continuity and not setting off the ignitors. Diagram...

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...

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...

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...
