    DiaLFonZo - Arduino Launch Controller

    Hi All, This is an on-going project that do not have a clear finish date. Most of it is think through aside the connections for the Battery & Ignitor extension. (most probably banana plugs) Not being a programmer myself, here is a few iteration of the firmware... Some milling of the...

    Arduino Radio Transceiver

    Hi, I am wanting to transmit GPS coordinates and altitude from an Arduino onboard a model rocket that will go 1km high, to another Arduino on the ground. The purpose is just to assist in finding the rocket once it lands. I was needing something cheap but also not too large (about 3-4cm). I was...

    Control oxygen flow hybrid rocket engine

    Hi all, I built a small hybrid rocket engine and I would like to control the arrival of oxygen in the engine with an arduino card. What do you advise me: a solenoid valve? A valve with a servo motor? If possible, could you specify a model? It's been a while that I'm looking for without finding...

    Help Plz. Arduino to calc rate of descent.

    I have a Nano, a Neo-6 GPS, an SD card, and BME-280. I'm wanting to measure rate of descent of different parachute designs I'm working on. What would be the calculations of the data gathered by the BME-080 (for altitude changes). Could I use the GPS for the rtc to timestamp each data...
