It may not get as much attention as NASA, Roscosmos, or even CNSA (China National Space Administration), but India’s space program has achieved some impressive goals. Just last year, in August of 2023, ISRO (Indian Space Research Organisation) completed their first soft landing on a celestial object with the Chandrayaan-3’s moon landing. That understandably inspired […]
Designing, constructing, and launching your own model rockets is a great hobby for learning more about the world of aerodynamics, computer simulations, and physics as a whole. But when it comes to actually lighting the solid rocket fuel to achieve ignition, the user normally lights a fire directly on a fuse or lays out a […]
Conventional hobby model rockets get their thrust from disposable motors containing an explosive propellant, like black powder. But unlike the gun powder in a firearm’s cartridge that uses a concussion-activated primer to ignite, model rocket enthusiasts ignite their motors using an electric arc. Simple launch controllers consist of little more than a battery, boost converter, […]
Eddy Robinson has spent the last six months building a model rocket complete with a thrust vector control system for stabilization, along with a correspondingly epic launch console. His “extremely overkill” controller is packed inside a rugged case and flips open to reveal an array of buttons, switches, and displays. Controls include an arm key […]
If you enjoy model rocketry, you may wonder just what the thrust curve of the motors you’re using looks like. In order to answer that question, YouTuber ElementalMaker decided to construct his own test stand using an Arduino Uno coupled to a 10Kg load cell with an HX711 amplifier board. The test procedure is started with […]
