    AspireONE- New Kid on the block

    Hey Fellow Rocketry Geeks 🤓 I've recently joined this addiction and can't stop. I'm new to Rocketry but not new to electronics, programming and mechatronics. Rocketry allows me todo all of the above. I live in Canada and LPR is my only choice. But that should not be a limitation. As a result I...

    Question about igniting backup B.P. charges

    Hey all, I had a quick question, So I am intending to have a backup black powder charge for the drogue and main parachute deployments. I have two altimeters that I am going to use. The first question is: I was going to have the main altimeter (an RRC3) fire the main charges. Then have the...

    Continuity Check Circuit Issue

    Hi All, I am attempting to make my own altimeter. I designed an ematch firing circuit which I believed should have worked and allowed the microcontroller I am using to detect continuity when activated (Like a commercial altimeter). However, when I assembled the PCB and tested it, the ematch...

    Altimeter Survey

    Hello, I am a student in the engineering magnet at Middleton High School. For our senior capstone project, we are making a telemetry capable altimeter. I recently posted a survey on this forum about current altimeter designs and we got excellent results so I figured we might as well post this...

    Temperature relation to electronics

    Does anyone have any experience with the effects of temperature on components in an electronics bay during a flight to say, 25,000 feet? The temperature at higher altitudes becomes low at 25000 feet, and I would like to know if there are any ways I can find out how components such as an...

    Eggtimer Quantum - No continuity but deployment test fires.

    Ive got a strange issue with my latest Eggtimer Quantum. It’s my 3rd and not seen this problem on the previous two. FWIW I’ve prob built around 10 kits with no major issues on initial startup. It boots up ok and the WIFI Connects. But when I put a load on the deployment channels, I dont get...

    What happened to Altimeter Three??

    Hello, For the last two years, myself and a group of people from my high school have been working on an experimental rocket and were using altimeter three because of the easy to use interface (and relative small size). We lost ours during our last launch and need a new one to continue the...

    Can someone identify this?

    Got this from a friend, he got it from one of his friends and had no idea what it is. Anyone have any info on it? If nothing else it's a cool piece to collect but I'd love to be able to fly it.

    Most Accurate Way to Measure Velocity: Accelerometer vs Barometer vs ?

    I need to be able to precisely measure a high-powered rocket's velocity after motor burnout. There is an onboard altimeter, as well as an accelerometer available to me. Which would yield a more accurate result? Also, any recommendations for implementing this with a real time system? If I...

    Ebay with Metal Bulk Plates - Wildman

    I received an electronics bay from Wildman Rocketry. It is a very basic kit, 1 32mm fiberglass coupler and two bulk plates (See Pictures). I have never worked with metal bulk plates before. I was wondering if I could get some ideas on how to pass the electrical signal from my altimeter inside...

    Altimeter vent holes

    About halfway finished with my new EZI-65 build. I am going to utilize a Jolly Logic Altimeter 3 for this rocket. Any ideas for vent hole sizes in the main air frame and how many? Also, my friend suggested rather than use air frame vent holes why not drill small holes in all 3 centering rings...
